Browsing: Circadian Rhythm
Circadian Rhythm refers to the internal process that regulates the sleep-wake cycle and repeats roughly every 24 hours. These biological rhythms are found in most living organisms, including humans, plants, and microbes, and are influenced by external cues like light and temperature. In humans, the circadian clock is located in the suprachiasmatic nucleus (SCN) of the brain’s hypothalamus. It plays a crucial role in determining the timing of various physiological processes, such as hormone release, eating habits, and body temperature regulation. Disruptions to this rhythm, such as those caused by shift work, jet lag, or poor sleep habits, can lead to various health problems, including sleep disorders, depression, and metabolic syndrome. Understanding and maintaining a stable circadian rhythm is important for overall health and well-being.
