Circadian Rhythms

Circadian rhythms are natural cycles of physical, behavioral, and mental changes that occur in a 24-hour period in many living organisms, including humans. These rhythms are controlled by an internal clock and are affected by environmental cues such as light and temperature. The significance of the circadian rhythm lies in its ability to regulate sleep, appetite, hormones, body temperature, and other bodily functions. Disruption of the circadian rhythm can cause serious health problems, including insomnia, obesity, diabetes, and depression. The use of light and dark to modify the circadian rhythm can have therapeutic effects on people with sleep or mood disorders. It is important to maintain a regular sleep pattern to keep the circadian rhythm functioning properly.
