Episode description
Story at-a-glance
- Photobiomodulation therapy utilizes specific light wavelengths — including 660 nanometers (nm), 850 nm and 1,050 nm — to stimulate biological processes, each offering unique tissue penetration and therapeutic benefits
- The optical window (600 to 1,100 nm) allows effective light penetration into tissues by avoiding absorption from hemoglobin, melanin and water, optimizing PBM efficacy
- Red light at 660 nm enhances skin health, collagen production and wound healing, reduces neuropathic pain and boosts cellular energy (ATP), ideal for dermatology and wound-healing applications
- Near-infrared light at 850 nm penetrates deeper, aiding muscle recovery and pain management, reducing inflammation and improving skin complexion, suitable for sports medicine and rehabilitation
- Light at 1,050 nm reaches deep tissues and brain structures, supporting cognitive function, brain health, ophthalmic uses, stroke recovery and detoxification processes
