Oh hey, it's your invisible aligners. You don't wear anywhere near twenty two hours a day and they know it and you know it. Alli Ward back with another episode of Ologies. I'm alive, y'all. I slept so many hours over the last couple of weeks dealing with this slu Who When are you listening to this? Are you turning the coffee pot on and feeding the dog? Are you on the seven a m. Train to work? Is it your lunch break and you have half a burrito spinding
slowly into microwave? Maybe the sun is setting while you walk to your car. Are you nursing a human who has decided to snack on your boobadge at four am? At least once a day. It seems we look at a clock and we're cranky about it, myself very much so all the time. So we are here to talk about why. But first we're gonna talk about you saying thank you so much for supporting via Patreon dot com slash Ologies, for sending in your questions that way, for
wearing Ologies shirts and hats from ologiesmerch dot com. We have some great new designs up by the bye, and for telling friends and maybe foes in laws about ologies, keeping it up in the charts by rating it and subscribing on all of your devices, and of course for leaving a review. You know I'm gonna a lurk them just like a gentle happy creep so I can read one back to you, such as this week's Megan Wint left for review and said I'm in bed with my What Is Real book and my binoculars to look out
at the moon all because of this podcast. Just when I thought I couldn't develop hobbies outside of my career, this podcast came along and made me love science again. I attend star parties, bake bread, got my flu shot for the first time because of this podcast. Everyone should give it a try, even if you hate podcasts like I did, because everyone should question, examine, and value our
little blips of existence in the world more often. Thanks for helping my serotonin receptors, dad word, Megan Win, thanks for getting a flu shot as someone who was just in bed for a week with it. I should have gotten one also well. Also shout out to rvecat Daddy who's going through a rough time in a tiny house with a few felines. May your next birthday not involve a divorce. I tell you, I read all of them, folks. Anyway, Crona biology comes from you guessed it, Greek friends always
putting things in our word holes. So kronos means time. Biology means the study of life. So it's a very real branch of science dedicated to understanding how temporal rhythms affect life. And that can be such as daily or weekly or seasonal or annual rhythms and circadian rhythms. I'll break that down. Circa means around da a day. So those are the kind that a lot of us might be most bent about because those are the daily rhythms. So we're going to get into it. So this ologist
I know from Twitter. She hosts the podcast Endocrine Disruptors, which dives into things like your adrenal glands and your ovaries and your nerds and how your hormones get jacked. So she got her bachelor's degree in biology at the University of Tennessee focusing on biokem, and her masters at Northwestern's neurobiology program with the focus You're ready for this sex Differences in circadian influence on alcoholic induced cut lakiness
and implications for alcoholic liver disease. She loves this stuff so right now, she's in the middle of her PhD at the University of Illinois at Urbana Champagne, and she says her first research love is circadian biology, but she's also fascinated by how hormones affect and are affected by daily patterns. So we get into it now. I wasn't able to make it to Illinois to record this, but I was thirsty as hell for this topic. Quite frankly, I needed to be scared straight when it came to
my shitty sleep patterns. They're so shitty, they're so bad. So she graciously crammed herself into the world's tiniest sound booth in Illinois on a hot July day, and we chatted over video screen about what happens in our brain when we sleep and when we don't sleep. We talk about jet lag and alarm clocks and how rest affects your gonets and chronotypes and giraffes and eyemasks and early
birds and night owls and botox and light pollution. So go tuck yourself in and let's wade together into the comfortable darkness with chronobiologist Catherine Hatcher.
Hi, you're here.
Hi, We've put you in a tiny booth across the country. Yeah, and it's Midwest summer, which means it's hot as balls outside.
I'm so sorry. It's all right. Bolt's character.
Yeah, brain brains, brains brains. And so now you are a neuroscience student. Correct?
Yes?
Are you? You're getting your PhD in neuroscience?
Yes, I am.
Oh my god, how did that happen?
Oh jeez. So I was one of those kids in college who thought I wanted to go to medical school. And I joined this lab that they were studying the impacts of different compounds on circadian rhythms and looking at very basic science questions. And so I joined this lab and I just wanted to do it to boost my resume. And I got about halfway through that semester and I was like, screw medical school. I don't like people. And
I realized how much I really enjoyed scientific research. Well, the world did not agree with me, and I didn't get into graduate school. When I first applied. I lied to like six schools and nobody accepted me. And that happens. And so I went and taught high school actually for a couple of years and then decided to go back
to school to get my masters. So I did a master's in neurobiology, and during that time I applied to PhD programs again and got in to two out of the flour I applied nice and one of them was one that I had applied to originally, and I was like, you guys didn't accept me the first time. I'm the same person, but I knew that I wanted to. This was actually my top program. So I'm at the University of Illinois down in Urbana, Champagne, which is basically just a bunch of corn fields and soybean fields.
So Catherine's worked on various neurobiology projects while there, but her PhD dissertation, by the bye is studying this class of compounds found in plastics and polyvinyl chlorides and makeup and fragrances to see how exposure to them affects sleep quality and depression in women who are starting to go through the menopause or like myself, whose ovaries quit early randomly. So these compounds are called tholates, and that word starts with a phdh and thalates appear to be just potentially
terrible for your body. And your endocrine system. But they are awesome for a game of scrabble. When you just have so many h's going back, you couldn't have always been interested in neuroscience has a toddy because you can't really poke brains as a we one, And did you get interested in science?
So I'll be one hundred percent honest. I was like the worst, one of the worst people for this story because I hated science for a very long time.
So this is good.
Yeah, I guess it's interesting. But I've always been fascinated by animals and I've always loved animals, and I should have realized. I think my sophomore year of high school at my school district, we took biology, and so I remember taking biology and doing dissections and stuff and we got to dissect fetal pigs and this is gross but whatever. So it was myself and two other people in a group dissecting this fetal pig, and then the teacher was like, if you get the brain out and like good quality,
then you get bonus points. So there I have, like challenge accepted. And then I just the two guys that were in my group, they were like, Nope, not touching that. I was like, fine, it's gonna be me. So then it was me doing it. But then I thought at the time or by the way, I did get the brain out and it was beautiful and my teacher was impressed.
How did you do it? Did you have to crack it like a coconut?
Yes, there's like an art to cracking skulls.
Are you ready for Katherine Hatcher? Get ready for Katherine Hatcher? So you got this pig brain out?
Yes? So I got this pig brain out. That's like my first remembrance of like anything related to brain that fascinated me. But it was more from a curiosity mechanical standpoint. But I was also one of those hits that was super fascinated by like weird medical mysteries and stuff. So I had this interest in medicine and physiology and this curiosity about it. But I thought that I didn't think that science was anything beyond medicine, Like I didn't understand
what science was. My parents and like my dad's a lawyer, my mom's an art teacher. They have no idea like anything about science.
So Catherine loved writing and being creative, but took an undergrad class in how muscles work and thought, well, this shit's cool. I'll just go to medical school, which turned into I'll study biochemistry, which turned into wait, I love psychology and human behavior too, so maybe neuroscience is like all of that. Yeah.
I thought the questions were fascinating. I have some people in my family who have alcohol addiction, and so this concept of like how does alcohol affect the brain has been something that's been really interesting to me, just as from a more personal standpoint, and so I was kind of trying to slowly pursue those questions and then realize, Like it was this realization that oh, science can be a career. You don't just have to be a medical doctor or a veterinarian or you know, a pharmacist or
something to be in science. You can do so many other things.
So time as a whole is ticket. So let's get to the nitty gritty of chronobiology. What is a circadian rhythm? How do you describe that to someone?
So my favorite way to describe circadian rhythms is that they are their behaviors or biological processes that exhibit some sort of twenty four hour pattern, which means we see the same approximate peak and prof in that pattern every single day. So some examples of what these would be. I think the most common people think of as sleep and wake activity, because that's obviously the most interesting to us.
Just immediately, we quote unquote sleep at the same time every day and quote unquote get up at the same time every day. Humans are weird because we can be conscious and make choices about when we get up or go to sleep. But generally most species they get up and go to bed at around the same time every day.
Is that just because that's when night falls and they're kind of more vulnerable.
Yeah, So there's some thought that you know, your circadian rhythm, at least with a lot of wild species or wild animals, is going to depend on whether or not you're a predator or prey and what you are hunting, what food is of interest to you. So an owl is going to be awake at night because it hunts mice, which are also up at night for the most part, most of them, and so the owl is going to of course be nocturnal because that's when it's food is available.
Goad soups on humans, you know, I think we have not adapted to be functional at night. Most of we're kind of weird. We've evolved to be able to make the choice of when we want to get up or go to bed. But for the most part, our food we were able to hunt during the day or you know, at the late parts of the day.
Or now you just take the yell aap and you just toggle open. Now you're like, what are my options here?
Seven eleven? Fine?
Yeah, what's on Uber eats today? What's whose delivery fee is the cheapest right now?
I know. I wonder if that means that people, say in New York, where they have more open late options, tend to have a different sleep cycle than people in say Sedona, which I visited, and their late night eating options are shit. I ate fruit salad from Circle K after a wedding sucked Sedona on blast.
But like, dif you get.
Married in Sedona, have a late night food option at your wedding.
Oh god, yes, oh my god. Starving, y'all.
I drove around Sedona, Arizona at ten pm. Nothing was open. I went back to my hotel. I had to eat the inside of a soggy tuna wrap with a spork in a cocktail gown. It was a beautiful wedding though they're still married, I still like them. Also, a circadian rhythm is something internal driven, but diurnal rhythms are just
regarding the day or night cycle. So an outside factor like light or temperature that affects your internal circadian rhythms, that's called a zightkeeper, which sounds like an Austrian word for like a wool bonnet or an antelope saddle. But yes, okay, light, But do you think that our environment, even in a city versus a rural area, changes the way that we sleep?
Absolutely?
Really, I think, and I don't.
I there's probably some evidence in some research done looking at the differences between rural and urban populations, but I think there's kind of two major drivers, one of them being light and then one of them being food availability. But I think probably the biggest difference, especially with humans,
is going to be the difference between light exposure. While there might be some light out in the country, it's not going to be as intense and bright as you know in the city, where it's everywhere you can't get away from it.
Okay. So I ventured into the wilderness of research, and I stumbled onto one twenty fourteen Portuguese study titled Differences in Circadian Patterns between Rural and Urban populations an epidemiological study in the countryside. So after analyzing sleep questionnaires of a few thousand people, these Portuguese scientists found that compared with the urban population, the rural population had earlier sleep
patterns Nadai. Rural folks also tended to have less what scientists call social jet lag, which is when you sleep in later on your days off and then you feel wrecked on a Monday morning. But they did find higher light exposure in the rural population, a higher prevalence of psychiatric disorders in the rural population, but fewer metabolic diseases. There was also a Bengali study and their sleep questionnaires revealed that urban adult populations had crappier sleep than the
rural ladies slipt the worst. So here we are thinking that the youth, with their gaming devices and meme screens and late night shenanigans have the crappiest sleep, But really we got a world of zombie moms and woozy women hormones to blame. Who knows now. Worst city in the US for light pollution. I looked into it and according to a study done this year by the website sleep Chunkie, Washington,
DC is the most light polluted sound pollution. You're wondering, look no further than my home, Los Angeles, which was rated the least peaceful place to live in America. I'm no data scientist, but is it any wonder that LA also ranks and I look this up the highest in the number of groupons sold for botox. Let's just stay up all night tossing and turning, and then easy peasy, inject botulism in our faces to look rested. What could go wrong?
There might be more of an inclination, or maybe people who are night owls are more attracted to city life because there's.
Nowhere to do.
Yeah, that's good point. Correlation, non causation.
Yeah, And so why do we need circadian rhythms? So?
Do they? Does regularity make us healthier?
So I'll answer first question. So why do we need circadian rhythms? We know that our bodies have evolved, All species have evolved with this twenty four hour pattern of light and dark, and circadian rhythms are more so related to the twenty four hour day. We think of this twenty four hour pattern of sunrise and sunset, and so
we've evolved to these conditions. So really we think that it's a way to optimize our biology and our behavior so that we can be the most successful in fitness and the most successful in terms of our reproductive ability, in terms of our survival. But the biggest thing is that we know that there's some sort of indirect or direct connection between circadian disruption and health.
What kinds of.
Say, negative effects happen when your circadian rhythm is screwed up?
How am I going to die?
So there's thought that there's increased risk of cancers, and yeah, I'm mainly interested in like reproduction and reproductive capacity. So I know that there's some changes in fertility. There's changes in increased risk of reproductive cancers. There's increased risk of metabolic disorders like type two diabetes. There's increased risk of obesity, but whether or not that's a bad thing, we're not one hundred percent sure. There's increased risk of stroke and
heart attack. So I've even seen things as crazy as if we disrupt and these are an animals, of these are in animal models, But when we disrupt circadian rhythms before an animal gets pregnant, the offspring has immunological deficiencies.
Oh my god, Oh my god. Yes, why is this happening?
What types of protein messengers?
Like?
What is Do you have any idea from a structural chemical standpoint why this is?
So there's this this idea of internal synchrony among our different clocks. So we like to say clocks in the field, of course, because we're talking about time.
It's about time.
So it's thought that each like, there's one part of your brain that's considered the quote unquote master clock that is called the super chiismatic nucleus. So if you saw me on Twitter, my name is super chiismatic. There's a reason for them. I am a little bit of a nerd.
Again that Twitter handle at super chismatic. She's committed to this tidy, tidy piece of brain anatomy, and I respect that.
So this part of the brain actually sits right above the optic chiasm, and so it's in the part of the brain called the hypothalamus, which is involved in regulating a lot of very basic systems in the body. So this little brain area receives direct information from light, it receives direct information from the retina, which gets stimulated when light hits it, so then that communicates chemically to that
part of the brain. Then that part of the brain sends signals all over to other areas in the hypothalamus, to other areas outside of the hypothalmis and the brain to the brain stem, which then those brain areas communicate to the body.
So the hypothalmis side note, is a small area in the center of the brain that's partly responsible for hormone release, and the super chismatic nucleus SCN is a teeny tiny part of that and it registers info about light and dark and it sends signals everywhere just to let your body know what's up out there.
So there's this main clock in the super chismatic nucleus or SCN, and that is thought to orchestrate everything going on in the body when it comes to light exposure. But then yeah, yeah, so when light exposure goes wrong. But then outside of the body, there are outside of the brain, there are other clocks, Like there's a liver clock, there's a clock in your gut, there's a clock in
your stomach, there's a clock in your muscles. And when we talk about clocks, we're generally referring to a set of proteins and genes that have been shown to be rhythmic, and almost every single cell in the body expresses these same genes, but we don't know their function in every area of the body. In the part of the brain I mentioned before, the SCN.
Again, super chismatic nucleus SCN.
We know that they respond to light, and then their rhythms change and respond to light, which is thought to lead to downstream changes in other proteins and hormones and other signals that would communicate to the brain the rest of the brain, but we don't know exactly their role in other body parts. So that's one thing that a
lot of people are trying to figure out. So the concept of internal synchrony is that this SCN is at a specific pattern, and all of your other organs and tissues are at a specific pattern every day, but when something goes wrong, they get out of whack and they quote unquote desynchronize, And so it's thought that this desynchrony is somehow kind of tugging body certain body functions to be performing when they might not supposed to be performing, or the brain is trying to do something when the
brain shouldn't.
Be doing something, please not.
Now it's probably much more complicated than that, but we don't. And I like, I know there's some hormones that are thought to be involved in regulating it. Some melatonin is a big one that a lot of people hear of. So when your circadian rhythms are when light, you're exposed to light at night, your melatonin rhythms get screwed up. When you're exposed to light at night, your cortisol or what's thought is your stress hormone that gets messed up.
So it's thought that those signals can also attach to different body areas and signal, hey, something's going wrong. And it's likely that the chronic exposure to circadian disruption is what's pausing all of these issues. So pretty much anybody in a city or suburban area it's exposed to light at night.
Oh god, Yeah, wait, what is your tell me about your sleep hygiene?
Out with it?
Oh god. So it's kind of ironic because I actually like run an Instagram account that's like dedicated to self care and like mental health for graduate students, and I'm like one of the worst people to ask about this.
Oh that's the bad news.
First of all, like, I have what I like to call sleep procrastination, and I don't I didn't make up that term. I think this is a problem with a lot of people where we're like, oh, my god, I have so much to do, and so you watch Gray's Anatomy for twelve hours instead of doing anything, and then all of a sudden you're like, oh, it's ten thirty eleven o'clock at night. I need to get stuff done. So then you work until two or three or four in the morning.
Yes, I've read my diary. You're reciting my diary.
So I'm definitely one of those. I try to sleep better, and honestly, like my sleep hygiene only needs to be adjusted when I start to get stressed out. That's when I tend to need to hone in. But most of the time I'm in my I'm on my phone in bed, I'm watching TV in bed. I'm so bad.
But I'm so much like blue light.
Yes, it's everywhere, it's everywhere.
Okay, so big cities have more light pollution, but what about the light you curl up with and personally jam into your retinas before bed? The blue stuff? Should we all be wearing glasses like Bono. Catherine says that the SCN is most sensitive to blue light.
Whereas red light. It's not picked up as well in the brain, so you you still sense it, but it's not going to stimulate those cells that contribute to this light signaling in the brain, so we see it. It probably has a minor effect, but it's not as dramatic and as intense as blue light.
Now, what happens if, let's say, hypothetically, you're a person who falls asleep with the lights on five nights a week, it's great, What is how opening in your coconut?
So I was thinking about this because I saw your question, and I think it would be because when we close our eyes, we still see the light. The light is still coming through our thin little strips of eyelids. So you're probably being exposed to dim light at night, which is maybe not as bad as bright light at night, but it's bad. So all the things that you would expect to come from light at night are going to be coming from having your light on while you sleep.
So there, Yeah, and the fact that you're doing it, like the fact that you're doing it all almost all of the time. Yeah, yeah, maybe you could get around it and like put the orange lights or whatever they are in your bedroom instead and it wouldn't be us. But then it's hard to see things.
That's very generous that you think this is occurring in a bed and not on the couch with a laptop under my face. So sleep procrastination, I'm gonna okay, I'm gonna research and aside on how to stop sleep procrastination. Okay, so side note. About five years ago a group of scientists from the Netherlands identified this phenomenon of sleep or bedtime procrastination, and they defined it as quote, failing to go to bed at the intended time while no external
circumstances prevent a person from doing so. So that last half the sentence is like it's your own damn fault.
So what causes this?
They think deficits in self regulation or having ADHD, or anxiety or perfectionism or work compulsion. I did some digging and one twenty nineteen Turkish study entitled Life is Short, Stay awake, death, anxiety, and bedtime Procrastination found that a fear of being a corpse eventually is one cause for sleep procrastination. So less time awake means less time to be conscious to experience life's rich pleasures, such as watching dog videos and going down social media rabbit holes to
see where your ex boyfriend went on vacation. So I read roughly seventeen thousand different blogs and websites about how to stop, and there was advice like take a nice bath at night and stop using your devices in the evening, give yourself an hour window to get ready for bed or on your to do list for the day, set a bedtime first, and then work backwards scheduling your entire day. In essence, the advice is like, suck it up, realize your brain hates you for doing it, and then knock
it off. Tipshit. Or maybe you could just go banish yourself to the woods for a while. What about people who go on like circadian cleanses and they go camping or they don't use artificial lights for like a week.
Does that reset anything? Does that help at all?
It probably temporary resets things, But let's be honest, if you go straight back to what you were doing before, you're the purpose of circadian rhythms is to be able to adapt to changes. So we don't quite know if like one small disruption of circadian rhythms has lasting effects on the body. It probably doesn't. It's probably the chronic exposure.
Like I mentioned before, this is the chronic So if you only go away for a week and you're living in the wilderness with the moonlight, it's probably not gonna be as beneficial as just making more permanent changes at home on a regular basis.
That makes sense. Yeah, Now what about animals.
Are there any animals that have really weird circadian rhythms that are like up and down and up and down.
Cats basically don't have They have circadian rhythms, but not in sleep wake activity.
Really, how does that work?
They just sleep all the time. They're carnivores. They don't have to worry about it. They eat whatever the heck they want. Well, house cats they're they're lazy and they'll eat whatever food you give them. But like, if you think about cats, they you know, they've evolved to be just eat whatever the heck they want whenever they can get it. They're kind of at the top of their food chain. They don't have to worry about what food is available and when, so they can kind of just
be lazy and sleep like all the time. I think they sleep like sixteen hours a day or something.
God, I know, right, but they're like koalas or something, don't Koalas and sloths sleep like sixteen eight twenty hours a day.
They sleep a lot. I don't know the exact numbers, but they do sleep a lot.
Yeah. Side note, of course, I google the animals that sleep the most, and giraffes apparently all have cocaine problems because they sleep four to five hours at night. Get up and take a spin class or some shit. I don't know. But giant armadillos get this, apparently sleep eighteen hours a day, and koalas and little brown bats have
been observed snoozing for almost twenty hours a day. But they were curious about sloths, so they fitted wild ones with little fitbits or something, and they showed they only sleep nine and a half hours a day. It's not too shabby sloths. Slaws are like, yeah, remember that time you needed a word for laziness, so you just called it usip.
What about some circadian flim flam any pervasive lies?
Yeah?
Than soap?
Get on so excited.
About this question. So let everybody know circadian rhythm is not a thing. There is not a circadian.
Rhythm, not singular.
It's not singular circadian rhythms. Like the words circadian literally means about a day. It's referring to rhythms that occur about a day. It's any rhythm in the body. You don't have a circadian rhythm. You have circadian rhythms because there's so many different rhythms in the body that act on completely different patterns. So we can't just refer to one thing. Now. I get most people are referring to sleepwake activity. That's generally what people think of. But that's just one example.
So if you say goo potty at the same time every morning, that's a circadian rhythm in and of itself.
Yeah, there is. Actually, there's like circaian rhythms in a lot of things you think of it. There's probably one.
Oh my god, can I ask you Patreon questions?
Yeah, oh my god. Okay, I'm getting to them a little bit early because we have so many and I highlighted a lot and there are so many questions that I want to ask, but I want the patrons to be able to ask them, so I'm just like, let's get into it. Okay, okay, But Before we get into your questions, we'll take a quick break to hear about some sponsors of the show who make it possible for us to donate to a charity of theologists choosing this week,
Catherine chose Stem Advocacy Institute or SIA. SIA is a global community of scientists, science communicators, and professionals who are passionate about strengthening the network of access to science, education and engagement. They give fellowships to scientists like Catherine, and they believe that EDU with a strong foundation in science is a critical component for global economic growth, social advancement,
and ultimately global peace. So a donation went to STEM Advocacy Institute, and there will be a link to them in the show notes, as well as to the sponsors who you may hear about right now. Okay, your questions, Okay, Patreon questions, so many millions of them. Forest dots high forest says why is mine so fucked up?
And what can I do to fix it? Just straight up?
So I have to say hashtag same. So I would say our circadian rhythms, most likely referring to sleepwake activity, Like I was just saying, they can get really screwed up. For a lot of reasons, but I think the most common for most people is lack of structure. So this
might be an answer to a lot of questions. But having a very consistent routine, especially with when you're getting up and when you're going to bed, and then when you eat food, those are going to be like the biggest two most important scheduled things to have to help improve your rhythmicity.
This just in I looked it up in Rhythmicity is a real word.
Our body loves consistency, our brain loves schedules, even a lot of us think that we don't, but like, yeah, our circadian rhythms. Do you know you have similar circadian rhythms to a moth. So you're not going to be like you're You're not as incomplex as you want to think you are. So having a consistent schedule, especially with light and food and sleep, those things are going to be the most beneficial for fixing your rhythms.
Oh my god, I feel very attacked.
Very see uh, Ellie Robert wants to know what's the best way to get blue light in the mornings when you wake up before the sun comes up. Is blue light in the morning good for waking us up.
It looks like there's some evidence for what they call a dawn simulation, So it's similar to those fancy alarm clocks that you can buy that like slowly bring light or using like a bright light simulator, so you can have those desktop ones that people use for a seasonal effective disorder. Using something like that in the morning can kind of trick your brain into thinking, Oh, the sun's up,
it's morning, It's time to like do stuff. So there's been some evidence to show that that actually improves our attention and improves our cognitive performance in the morning, as opposed to not using them.
Are alarm clocks kind of evil when it comes to circadian rhythms? Or are they just a tool we need to stay on track to circadian rhythms?
I think they're a tool we need.
Now.
I've noticed mine has a really bright light that I can't dim, so I should probably get rid of it and get a new one because I actually like can see it through my eyelids when I'm har sleep. But but yeah, I think they're more so a tool to kind of keep you consistently on schedule, especially when you have to get up and go to sleep at a specific time of day and you don't have as much flexibility.
Man, we need what we really need, hear me out.
We need alarm clocks that are sleep clocks that are like, and you're in bed.
You know what I mean.
Yeah, Like, we need a ten thirty alarm that's like, okay, all right, fucker, time to brush your teeth.
Have you tried doing that on your phone?
No, but tonight's might be night number one.
Okay. Side note when it comes to waking up, if you're in the market for a new morning alarm clock, I looked for the weirdest for you, and there's one called Clockie that's on wheels and it runs away from you until you catch it and turn it off or I guess set it on fire if you want to. There's another that requires you to shoot a laser pointer at a target before the alarm shuts off. There are bedside mats you have to stand on before they'll stop wailing.
There's the terrifying sounding shot clock that seems to zap your wrist, maybe with an electric current, until you accept that it's a new day. There's another that's called the sleep Squad that utilizes a police siren every morning. I don't know why they called it sleep Squad when they
could have named it the Wakey Brigade. Also, I found a four hundred and fifty dollars option that makes poured over coffee at your bedside, and I don't know why you couldn't just use like a thirty dollars Black and Decker coffee pot with a timer instead. It's done in
my business. But in terms of the most potentially sculptural, there is a contraption called a dream Time water alarm, and it relies on you filling it at night and then a steady drip of water all night changes the balance on a scale until, like a soft bill thing gets hit in the morning. It does not, however, spray you in the face, which is what I was looking for when I stumbled upon it. Oh. When it comes to light based solutions, there are all manner of sunrise alarm clocks.
They have great reviews.
There are higher end ones by Phillips that are a couple hundred bucks to like the twenty dollars home Labs options, because all of us know too well that the sound of an iPhone alarm brings deep terrible morning dread. Now, what about if you use it the night before you wanted to know. Logan Levo asks, is using my phone
for a while before sleep actually fucking me up? Like my dad insists, mister, Honestly, because we also have light and TV on, just your phone is probably not as bad as we want to think it is.
There's a lot of other light factors that are fucking us up. Let's be honest. But there is some thought that because of how bright it is and how close it is to our faces, that it might be more stimulating than a TV like across the room or a dim white light in your lamp with a lamp shade. So it is possible that it's more fucking upness, but we're not one hundred percent sure.
New words rhythmicity and fucking upness, so put those in your pocket now. A few of you had sleep mask questions. I'm looking at you, Emily Read, Julie Bear and Amanda Jay while I'm looking your direction, but I don't see anything because of the mask thing.
Do you have a sleep mask that you prefer? Do you sleep with a sleep mask?
I do sleep with a sleep mask, and I bought whatever was relatively affordable on Amazon as long as it blocks out all the light and doesn't like fall on my face. I sleep with a blanket on top of my head, though, to be honest with my partner snores. So and a machine and two fans because I'm a mess. I have a travel fan that I actually fly with me when I go places.
Oh my god, I love how prepared you are.
I'm very picky when it comes to sleep, so I try to do as much as I can to make it happen.
There's this great invention.
I covered it on Innovation Dation and it's called a bee fan, and it's a fan that sits at the foot of your bed and it goes up in the bottom of your covers and it targets just one person in bed, so if one person isn't hot and the other is, and it goes up and it just like goes under your covers. It's so magical. It feels like you're in a marshmallow. And yeah, it's called a beefan. The guy who invented it invented it for his mother in law who is going through menopause. That was like awesome, Yeah,
I know. And it's like I've been in a bed with it and I'm like, oh, that's running nice.
Yeah, this is a side note, but it's relevant to what we're talking about. Temperature is very important for sleep, Like people who are like, oh, I like to be hot when I sleep, and like, no, your body actually decreases its temperature at night time so you sleep better. Like, it's actually better to have a slightly cooler space when you're trying to sleep.
Do you think that's because evolutionarily we just got used to night being cold.
Probably, like it's always relatively cooler at night than it is I shouldn't say always, but most of the time relatively cooler at night than it is during the day.
Okay, some of you wanted to know if sleeping under a tree outside might help your screwed up circadian rhythms, like Anna Thompson Monster Cat and Anita Starzynski ass at Home, I'm a night out. When I go camping, I so easily fall into the rhythm of sleep when it's dark, awake when it's light. Why does this happen so readily? And is that what my body actually wants?
Yes? Ah, And you're probably away from a lot of light pollution, and you know you're Our bodies developed with this. Our brains developed with this light dark cycle. So if we go back to again where we can easily adapt to the light cycles. But this is like naturally what we would normally be around now. Will it be the same in a thousand years if the planet still exists,
when when you know we've adapted to light pollution? I have no idea, But at least for now you know we adapted and we evolved to normal light dark cycles being the sun and the moon and the sun and lack of sun. So of course we're gonna feel comfortable and happy and at least our sleep will when we're back with nature.
Mm hmm. That makes me want to go camping and cover myself. Indeed, just do me a favor.
Check your crevisers.
Thank you. Now all of us, I'm sure want to know about the blues and the blue light and anxiety and sleep, such as Evan Jude, Chris bur Or, Heath Allen, Becca Bee, Meghan Lucien, and Sarah Wingfield, Cranilation Hassan and Sarah Clock, Casey Rose and Becky Baker says why do I need to sleep fourteen to eighteen hours a day when my depression flares up? Also asking for a friend. Is that why some people have clean houses and obedient children?
So, oh, this is a good question. I think that I'm not one hundred percent sure, but I think that with depression, one of the symptoms is fatigue. So it might be that we're trying to combat fatigue with more sleep instead of our normal whatever. If you're Alley, probably three hours of sleep, if you're me, like maybe six or seven hours of sleep. You know, normally that's what we get, but then we try to make up four
feeling fatigued when we're depressed by sleeping more. Depression and sleep are very, very very tightly tied together, and so it's really hard to figure out which comes first. Are you depressed because you're lacking sleep, or are you lacking sleep and feeling fatigued because you're depressed. It's likely a some combination of the two.
Okay, side note, I looked into this, and I'll give you just the gist. Mental health and sleep are very linked. Sometimes issues are a symptom of mental illness, and sometimes they can cause mental troubles. Often they just keep cyclically making the other worse. So what can you do? You'd see a doc, but before you go in. You might want to keep a sleep journal for two weeks to show them when you slept for how long, what troubles
you had. Doctors also suggest a bedtime schedule and a routine, of course very helpful, as is limiting stimulants all together, or at least in the afternoon. They suggest getting plenty of sunlight or using a light box that mimics the sun if you have seasonal depression, especially up here in
the US where we're in the darkest days. And I'm not talking politically, I just mean winter in the northern hemisphere, speaking of which, some patrons had seasonal and latitude questions, such as Misty Clardy, my Montana cousin, Nathan Bronick, Hi, Michelle Lee Deli Dames, and first time question asker Evan Jude asks how many humans, plants and animals who live closer to the poles and experience continuous daylight and nighttime around the winter and sss like white nights in Russia?
How have they adapted or evolved differently?
How do they deal? And have you seen Midsummer?
I haven't seen Midsummer? Do I need to see it?
I think it's about a white night.
I think it's a horror movie that it takes place, you know, like a continuous daylight night wraw.
So my friend is actually one of those people that's lucky and gets to go to Antarctica. So I've tried to ask her, like, yes, yes, she's boss. I tried to ask her, you know, what is it like there in terms of because they go during the Antarctic summer, which is our winter, but then it's light all the time down there, and you know, she said that, yes, it's harder to get sleep, but most of the time they you know, they have ways to control the light
and dark in their facilities. But there's really not a lot of research done on the people that live in these polar areas. And I think I recently saw an article that they're finally starting to do studies on the resident scientists that live in Antarctica, which is like, that's the perfect population of people. It's very controlled environment, very
controlled food, a lot of controlled factors. So I think they're finally going to start looking into it because my educated guess would be that there is probably higher rates of depression, there's probably higher rates of things that we associate with continuous light exposure. We haven't adapted to those
areas yet as far as I know. I could be wrong, but there's probably increased risks of all these morbidities that we associate with light at night exposure in these people that are at the higher or lower ends of the earth. Also like during the long or during the winter their respective winters. I think that's probably where the increased depression might poke itself through, because they're not getting enough light. Like we need light even if it's not warm outside. We need light exposure.
Crick aside. I poked through some reports about mental health and latitude and found one really fascinating study which looked at how rare suicide was in pre colonization Greenland versus modern lifestyle, and apparently birth month and birth season tended to affect those kind of mental health issues. And while those types of deaths increased a lot post colonization, the seasons had less of an impact because of the introduction
of artificial light. So knowing the amount of light and darkness that our super chismatic nucleus receives can have major impacts on our hormones and mental health. What about what we futs with the clock itself and throw the whole system off twice a year. Julie Bear asks daylight Savings Time abolish or keep a ball as okay, she says, we can't be friends if you say keep Actually.
The Society for Research on Biological Rhythms, they just released a statement about why we should abolish the daylight savings time. But they so the people who are in charge of studying circadian rhythms and other biological rhythms are like, get rid of it. So it's a waste, like we don't need it anymore.
Mm hmm. And don't they say that when they kind of shave off an hour of sleep, there's a lot of heart attacks and a lot of health problems occur that like the following week after I've read that somewhere.
It's basically jet lag. We're forcing jet lag on people.
That sucks.
Oh and I know that there are questions about jet lag. Okay, we're gonna get to those in a sec But first, another very important question. Julie Bert also wants to know do you giggle and snort when you hear and say the word diurnal because it sounds like a pair of journals next to each other.
Yes, okay, good.
It's a fun word.
It's a fun word that makes you feel better.
Patron Alyssa also asked his next question at Simmons says, I have read that folks who are blind, even with no light perception, still have melatonin cycling and diurnal rhythms. So what alternate mechanisms other than visual perception do our bodies have to regulate our circadian rhythm?
Like does our skin know that it's light out?
Our skin doesn't know. But I'm actually really excited about this question because we didn't get to talk about these little guys. So it's not actually the visual cells in our retinas that recognize light. So they do obviously, but not for circadian rhythms. They are just doing it for
visual perception. So there's actually these other little guys. They're called intrinsically photosensitive retinal ganglia cells what ip rgc's basically thank god, but there are these I think they make up less than five or ten percent of the cells in your retina, and they sense light, which most of the cells in your retina do, but they sense light and send it specifically to that super chismatic nucleus or SCN. So they're the ones that are like, hey, masterclock, light
is happening right now. So they're the ones that are communicating directly to that brain area. Now, depending on why an individual is blind, there are different reasons why a person might be blind. If those cells are still intact, they're still going to have circadian rhythms, They're still going to be fine when it comes to perceiving light and dark in the sense of regulating biological rhythms in that way. So if there's some different reason and those cells are
no longer intact, they will actually no longer exhibit circadian rhythms. Well, they will, but their bodies are basically constantly in what we call free running, which is as if you were to throw somebody in a cave in the back of a cave and have them be completely isolated from environmental cues. Oh wow, So it depends on why in individuals blind. But some individuals who are blind can still have sensing of light through those specific cells.
Oh, whoa, that's that's crazy. That's cool.
New question asker Lauren Marie asks, why do I feel like a sack of shit in the mornings when I've had eight.
Hours if oh jeez, I mean, there could be lots of things, So things that make you feel like sacks of shit. Even if you get enough sleep, or what we think of is enough sleep, maybe you consumed something, some substance that made your sleep crazy. So alcohol puts you to sleep but does not help your circadian rhythms at all, so it makes your sleep cycles kind of wonky. I don't know the specifics, but I know it's not good.
Hella fast. I looked this up, and alcohol can inhibit rem sleep, which is the most restorative type of rest. It can also wake you up in the middle of the night and make you go potty.
I mean, it could be that this person needs more or less sleep. That could be a fun experiment to give a try. Some people do better with exercise. I get specific times of day, so depending on when this person's exercising. I've read some places that like heavy exercise in the evening is not good. But then I can I know anecdotally I can go to a boxing class and be fine. But I think it just depends on
your needs. I don't think there's a straightforward answer for why eight specifically eight hours of sleep makes you feel screwed up. It probably depends on a lot of factors.
That's a good call.
And so many patrons asked, and I will put their names in an inside and I will read them quickly. These folks are Elise Knowles, Don Schwartz, John Yurick, Renee Jennings, Megan B. Pearson, Catherine Harshman, Mark James, Michelle, Lee Becadecker, Celia Ford, and Hallie who all asked about naps and about segmented sleep.
Hmmm.
And this notion of like sleeping and then waking up in the middle of the night for a couple hours and going back to sleep, is that really a thing.
I have not found any definitive evidence indicating that that is actually beneficial. At the same time, I haven't found any definitive evidence saying that it is hurtful. Now, the only thing that I could think of that would make this bad would be as if you're exposing yourself to more light at night because you're waking up in the
middle of the night. So if you're getting up in the middle of the night, it probably is not a good idea to then get on your phone or like go watch TV for three hours and then go back to sleep. I don't know what you could do well I do know a few things that you could do in the dark, but you know, you know, I think you know, you'd have to maybe try something that's not
getting you exposed to more light. There is some evidence that things like napping during the day, as long as you don't take long naps, that that is like a normal aspect of like human sleep patterns, especially because we eat a lot during the day. It's hotter during the afternoon generally, and so those types of cues are like making us sleepy, and so we take a little quick nap and then we're fine, we can get up and move on. But I haven't seen a lot of evidence
about segmented sleep, especially at night. Thing that I've heard a lot of people talking about lately. I think it was a historian or somebody who brought this concept up.
Mm hmm.
And then that's kind of all we've gotten since.
Yeah, Okay, So alongside rhythmicity and fucking upitness, this is another good pocket word, and it means of the dawn or dusk of the gloaming. It's great crepuscular. I regree wants to know what is up with crepuscular animals. How does that work? And how is that cycle advantageous to them?
I think it comes back down to what are these animals eating, what are they foraging for?
I love this question from Vitiepong.
Does going early to bed and early to rise actually make you healthy, wealthy, and wise?
I'm gonna say it depends, so depending on what your chronotype is. My chronotype is whether or not your traditionally we say night owl or daylark, whether or not you are a person who functions better during the evening or functions better during the morning, or somewhere in between. That's probably gonna make you more wise sticking to that schedule healthy probably depends on your light exposure. Again, it's all coming back to light and then wealthy, good luck, That's
all I say. But yeah, I would think the biggest thing is going to be related to chronotype. But then also depending on what job you choose, and maybe there's some correlation between our chronotype and what jobs we tend to gear toward. But yeah, I would say chronotype is probably going to be the biggest determining factor, which is a thought to be potentially genetic.
So yeah, and so many patrons asked that question.
Many of you little birdies had chronotype questions i e. Night owls versus morning larks, such as Stephanie Berherdies, Sarah Jane James, Chelsea fruit Fly, Molly Henning, Jasmine McLean, Michelle Miner, Anna Thompson, Hannah Claire, Rachel Mount, Sophie Cosino, M mcglide's game, Teresa Pasanova, Justin M. Gifford, Charlotte Field, Keguard, Henny Bergstrum, Kelly Brockington, Aaron Pandora two first time question asker Lara Durkovich,
Erica Butler, Madeline Winter, Bree Johnson, Charlie Wong, Heather Wood Bird, Beatrice Bilacuava Heath Allen, Cayla Perez, Sarah Sexton, and Erica. Is there such a thing as a night owl in an early riser? Is that a thing?
It is a thing, and it's a thing too depending on age, So our chronotype actually does change as we age. So obviously, like children tend to be more daylarks, teenagers are night owls. That's not a lie. It is act like a thing. And then as we get older, we move more and more toward daylarks, and older individuals tend to wake up earlier in the day, but their sleep is all screwed.
Up anyways, Why is their sleep screwed up?
So one thing is changed in hormones, So lack of hormones or extreme levels of hormones compared to what would normally be occurring during quote unquote reproductive age. But then also it's thought that the areas that are most involved in regulating circadian rhythms age as well. We don't know what that aging looks like, but it's thought that those brain areas, just like other brain areas, could potentially be aging and not function as properly as they normally would.
Oh wow, Yeah.
Because one patron asked about older folks and why they get up so early, Greg Wallack asked, Ever since I got a weighted blanket, I fall asleep with the lights on constantly?
Is that bad? But Greg Wallack wants to know.
Also, do you like the song day Sleeper by Rim where Michael Stipe actually kruns about circadian rhythms?
The kind of.
Is it bad that I haven't heard it?
I'm gonna have to send it to you. How dare you?
How dare you not getting a pH d until you can karayoke that entire song? I know?
Like the really popular rim song, but.
Well this is about to be perhaps your favorite. I'm gonna send it to you. Oh I do want to get to one more that? So many patrons asked patrons, I'm looking at you. Barb Wilkinson, Amanda Inkn, Sarah the CHESSI, Sam McCarthy, Jim Spicker, Danny Cue, James Capaldo, Riley mckinnis, Emily Tudorace Raymond j Deutsche, Rachel Fallon, Jana Vuznowski, Joey Todb, Heather Densmore. Y'all had some real jet laggy questions, mainly
how not get this? What strategies for combating jet lag are there without using medication?
Do we just have to suffer through it?
Or are their behaviors we can to adjust faster and more easily, Like what is jet lag?
What's happening?
So jet lag? I think is generally thought to be again the desynchrony between our internal pattern and what we are used to versus whatever is happening outside of us. We are basically going from hey, I'm used to East Coast time or Central time or whatever you're used to that light pattern and then all of a sudden, literally within a few hours, You're in a completely new lighting pattern and completely new social cues, completely new food cues. So all of a sudden, your body is like, oh shit,
what's happening? And so you know that's the actual scientific term that's true. And so it's thought that maybe there's this the brain is slowly but surely trying to catch up, and different parts of our bodies can catch up with this new timing at different rates. So I would say there's kind of two, maybe three things that seem to hold the most weight in terms of resynchronizing yourself to your new environment, depending on how long you're going to
be there. Honestly, if you're only going to be somewhere for a couple of days, it's not worth your time. Just deal with it and go back home and go to normal. But if you're going to be somewhere for like a week or so, I would recommend trying to resynchronize your schedule to whatever your new schedule is, but doing so in smaller increments, like if you could change your schedule every fifteen minutes every couple of days, that's probably going to be more beneficial than you just trying
to make it all happen at once. Yeah, there's some thought that we can adjust to fifteen minutes of some magic number, that it's easier to adjust to that change than like an hour or two hours or three hours. Now, that's hard to say. When you jump from like New York to Sydney, Like God, your brain is probably a mess.
But and then eating on a regular schedule, trying to sleep on a more regular schedule, even socializing on a regular schedule, that will help cue your brain and your body to know what time it is or what the new time is.
Oh, and I realized later that we didn't touch on circadian rhythms and shift work enough. And a bunch of you, many of you, too many of you to list, had questions Mcmanusaur, Michael, don Eweld, Nelson, Vietorro, just a few of you. So many others asked essentially what can shift workers do? Or how bad is shift work? And I wish we'd talked about it more. So email Catherine, and I asked, how fucked are shift workers? She wrote right back, and I shall read it verbatim. She says, generally speaking,
shift workers are fucked. We don't quite understand why. But when looking at disease risk. Shift workers have increased risk of developing a multitude of diseases, including cancers, metabolic disease, cognitive decline, etc. We don't know why. It's likely a mix of our physiology going out of whack, like your hormones go crazy, your immune system goes nuts, so on. This is obviously mediated by sleep disruptions, but we don't
know to what extent. Another interesting tidbit she says is it's not just the light exposure during shift work that's fucking us up. So our brain and our body are like, ah, what time is it? So your liver thinks it's noon because you're eating, but your brain thinks it's two am
because it's a dark outside. And yeah, we don't know exactly what's going on here, but shift workers are a mess physiologically speaking, at least, so shift workers heart goes out to you and your heart, I know, it's so hard.
Now.
We did a two part Zonology episode last year, and as we noted in that one, shift work is listed as a carcinogen. The yikes, And I don't know what the answer here is because shift workers are literally saving people's lives and oftentimes you don't have a choice as to what your schedule is for work. You have to go where they pay you, so be nice to a shift worker. I think there should be a national shift
Worker's Day. We should all have to get up and give you presents in the middle of the night, just to see what it's like one time. So I don't know, but I want everyone to take care of themselves as best they can. So the main point, let's get control of our sleep. People, do what you can. A lot of folks asked about how much control, though is too much?
Like what about sleep hacking? Rebecca Wendell, Joey Tabb, and ron LeBlanc wanted to know, what do you think of all the tech bros that are trying to hack their sleep and intermitten fasting?
Are you like, come on, I'm.
Sure there might be some small benefit to it, but it's I've heard recently of like people trying to hack for till using light, and I think I'm like, maybe maybe I would say if it doesn't hurt you, sure, why not, But there's not enough evidence to say that it actually works. So that would be my one caveat is go into it knowing that we don't know if it works. At all. I've heard of people like trying to hack circadian rhythms or force themselves to be one
way or another. To some extent, we can, but we only have so much control over what our body naturally wants to do.
PS. I just went down a rabbit hole reading about people who sleep on magnetic pads and they takee electrodes to their face and nap for a few hours at a time, all day and all night. Folks who strap ice packs to their body. Sounds like a giant pain in a biohacker's ass. PS. Do you need to fall
asleep quickly? I shared this in the Somnology episode. But my mom taught me a brain trick where you think of a category like fruits or movie titles or things you'd find in a purse, and then think of something that starts with an A, and then something starts with a B in a C and on and on alphabetically until you drift off. We call this the fancy nancy, So I hope it helps. If you need a tactic to lull you into dreamland, I use it all the time.
Thanks mom. Okay, moving on m HM and last patroon question, Ali Cooper wants to know blackout shades, friend or foe?
I would say, friend, Okay, so.
Even if the light doesn't come in in the morning, is it better if use blackout shades and then you just like wake up at six like all right, light here we come.
I would say, if you could, maybe in an ideal world, if you could have blackout shades, red or amber light bulbs in your house at night, and then maybe one of those fancy sunrise alarm clocks uh huh and things like that that can slowly simulate an normal light dark cycle, that's probably gonna be the most beneficial to us than just like one thing. If you just put blackout shades, you're right, you're gonna be blocking out the daylight in the morning, so it might be harder to wake up.
But then if you add a little sunrise simulator, that's gonna wake your little butt up easier in the morning.
So you know where we can all just sleep on the porch with no light pollution.
This big old, ugly street lamp that's like right outside my bedroom window that just makes me sad every time I see it. Kill me slowly?
What else just kills her?
Okay? Worst thing about your job.
Shittiest thing about your job? What sucks? Okay, other than me cramming you into this like tiny hot recording booth in July.
Honestly, the recording booth isn't that bad. It's the literal I don't know if you can see it, but like footstool that they put it there, my butt it is so sore. It's fine. It's basically like simulating a squat for an hour and a half, but my thighs will be glorious. So I wanted to say emails because they suck, but I'll be honest. I'm somebody who I check my email like thirty times a day because there's something satisfying
about getting an email. I feel like I'm wanted. So really, the thing, and this is, you know, anybody who's potentially interested in doing circadian rhythms research. There's this running joke that in order to study circadian rhythms, we have to fuck up our own So my master's experiments, I would have to go in from like ten to eleven at night and then be back in lab at six am
in order to run my experiments. I've done experiments here at Illinois where I had to be in lab from like seven pm to like five am, checking animals circadian rhythms research be prepared to not have any more circadian rhythms, like just oh my god.
So that I mean this is like doctors. Doctors have like the worst health yep, what is the best thing about what you do? What do you love the most about it? Or about circadian rhythms?
So I'll answer this with two things, so I'm gonna cheat. So my favorite thing about being a scientist in general is like that moment where like your data start to slowly make sense, and they never really fully make sense, because that's life. But when you start to create a story with your data, it's some of the most exciting
exciting moments of your life as a researcher. And then you get to talk to people about it, either through podcasting or through social media, or through conferences or writing papers. It's some of the most exciting times of being a researcher. And then also you start to develop new ideas and new questions because science now or ends about circadian rhythms
in general. We didn't get to talk about this, but circadian rhythms don't just regulate hormones, but they are also regulated by hormones themselves, So like things like estudial or estrogens in testosterone and cortisol and all those fun hormones we like to talk about, those actually feedback and regulate circadian rhythms too, So like circadian rhythms don't just do things, but they also then get feedback and get regulated by not just environmental cues but also internal cues too. And
I think it's just so fascinating. It comes back to my love of homeostasis again. I don't know why, but it exists.
So I'm realizing in summation, I can't treat my body like a robot. I'm a human organism, and I have to treat it at least as nicely as I would my dog.
Yeah, love your dog, Love.
You, right?
I mean I would never expect poor dog to like, not eat for most of the day because it was like working, and then just give it a bunch of doughnuts and pepsi and then keep it up all night and be like, what, why do you feel like shit?
You would never do that to an animal.
Though, No, we're not machines.
This is interesting.
I feel like the takeaway from this is it we're fragile beings.
We need tenderness and sleep and food schedule in schedules and routines, even though we hate them. Oh my god, so routines are our friends. Oh oh.
Sleep and now insomnia is a completely different beast. Insomnia's needs tender love and care from a different perspective. But just like sleep procrastination, general sleep difficulties like trouble getting to sleep that's not related to insomnia, Get a damn schedule.
Get a damn schedule.
Thank you almost doctor, doctors orders.
Yeah.
