Circadian Biology

Circadian biology studies the natural, internal processes that follow a roughly 24-hour cycle, influencing sleep, mood, metabolism, and hormone release. These rhythms respond to environmental cues, primarily light and darkness, helping organisms adapt to day-night cycles. In humans, circadian rhythms regulate sleep-wake patterns, making it easier to feel awake during the day and sleepy at night. Disruptions to these rhythms, such as shift work or excessive screen time, can impact health, leading to issues like insomnia, depression, and metabolic disorders. Understanding circadian biology can enhance well-being by promoting better lifestyle choices aligned with our natural cycles.
