The video traces the birth of the circadian rhythm to the earliest life forms, highlighting how exposure to the Earth's 24-hour light-dark cycle shaped biological processes.

This video introduces the Lume App, a revolutionary tool that harnesses light science to make your body's natural circadian rhythms visible, enabling you to track sunlight exposure in real time and receive personalized insights to optimize your hormonal balance and overall well-being.

Learn how syncing your meals with your body’s insulin rhythm can boost metabolism, prevent late-night energy crashes, and protect long-term health.

This video explains social jet lag, the misalignment between weekend and weekday sleep patterns, and how even small shifts in light exposure and wake times can disrupt circadian rhythm. It highlights the physiological effects on energy, mood, and sleep, and offers practical strategies to restore balance through consistent light timing and recovery habits.

This video explains the two-process model of sleep, distinguishing between Process S (sleep pressure) and Process C (circadian rhythm). It shows how adenosine buildup and the body's internal clock interact to create the sleep gate, the ideal window for falling asleep, and how caffeine, late naps, or poor light exposure can shift this alignment and disrupt restorative rest.

This video explores the skin’s circadian rhythm and how its internal clock regulates protection, repair, and cell activity across the day. It explains how melanin production, UV defense, and nighttime recovery follow precise timing, revealing how sunlight exposure, sleep, and daily rhythms shape skin health and resilience.

This video explores how growth hormone follows a daily circadian rhythm and how timing influences recovery, performance, and energy. It explains when growth hormone peaks during sleep, how consistent sleep and exercise schedules enhance repair, and how cortisol balance, light, and meals work together to optimize recovery and growth.
