Sleep and Circadian Rhythms

Sleep and circadian rhythms are interconnected biological processes that regulate when we feel alert and when we feel sleepy. Circadian rhythms are internal, roughly 24-hour cycles influenced by environmental cues like light and darkness, guiding various body functions such as hormone release and body temperature. Sleep is a natural state of rest that aligns with these rhythms, helping the body restore energy, repair tissues, and support brain function. Disruptions in circadian rhythms, such as shift work or jet lag, can impair sleep quality and overall health. Maintaining consistent sleep-wake times and exposure to natural light helps keep these rhythms synchronized.
