Circadian Rhythms, Sleep, and Well-Being

Our bodies run on internal clocks called circadian rhythms, which influence sleep, energy, mood, and overall health. But artificial light, irregular schedules, shift work, and constant stimulation can throw those rhythms off balance.

In this lecture, UC Berkeley psychologists and neuroscientists Dr. Lance Kriegsfeld and Dr. Sheri Johnson explore how circadian rhythms shape both mental and physical health, what happens when they become disrupted, and why staying aligned with natural day-night cycles matters more than we realize.

Blending neuroscience, psychology, and practical strategies, this lecture offers an accessible look at the hidden systems regulating our daily lives, and how small changes to sleep, light, and routine can help us feel healthier and more balanced.
