We were built to live in rhythm with the natural world, yet many of us now spend most of our days under artificial light and behind closed doors.
In this webinar excerpt, Zaid K. Dahhaj explains why he believes that disconnect may have important consequences for health. Our circadian system responds to powerful environmental signals such as daylight, darkness, sleep timing, movement, and when we eat.
When those signals become chronically misaligned, the effects can extend far beyond feeling tired. Circadian disruption has been associated with changes in metabolism, hormone regulation, inflammation, sleep, and other processes involved in long-term health.
It raises an important question: what happens when an outdoor, light-responsive species starts living almost entirely indoors?
Join Zaid K. Dahhaj and Dr. Ron Ehrlich for the full conversation as they explore circadian biology, light, modern lifestyles, and the relationship between our internal clocks and health.
