Episode description
- Your immune system doesn't simply weaken with age; it reshapes itself in ways that change your risk for infections, cancer, and autoimmune disease, which affects how well your body recovers and stays resilient over time
- Women develop a more reactive and inflammatory immune system as they age, which strengthens defense against infections but raises the likelihood of autoimmune conditions where the body attacks its own tissues
- Men experience fewer overall immune changes but are more likely to develop silent high-risk cell patterns linked to cancers, allowing disease risk to build without obvious warning signs
- Your lifelong exposures to infections, stress, diet, and environment create a unique "immunobiography" that determines how effectively your immune system responds to threats later in life
- Daily habits such as nutrition, sleep, stress management, and sun exposure directly influence how your immune system ages, giving you a practical way to lower inflammation and improve long-term health outcomes
