In this Huberman Lab Essentials episode, I explore how different wavelengths of light affect the human body and how light exposure can improve sleep quality, mood and daytime alertness while supporting healthy hormone regulation. I also discuss the therapeutic use of ultraviolet and infrared/red light for a wide variety of benefits, including improved skin health and offsetting age-related vision loss. I explain the biological mechanisms behind these light-based therapies and offer practical tools that listeners can use to improve both their mental and physical well-being.
