What Circadian Rhythm/ Body clock is ?

Circadian Rhythm, also known as the body clock, refers to the internal process that regulates the 24-hour cycle of physiological and behavioural processes in living organisms. This includes the sleep-wake cycle, hormone production, and metabolism.

The body clock is controlled by a small group of cells in the hypothalamus called the suprachiasmatic nucleus (SCN). The SCN receives information about light and dark from the eyes, which helps to synchronize the body clock with the external environment.

Circadian rhythms are found in most living organisms, including animals, plants, and even some bacteria. In humans, disruptions to the body clock can lead to a variety of health problems, including insomnia, depression, and an increased risk of certain diseases such as diabetes and cancer.

To maintain a healthy body clock, it is important to have a consistent sleep schedule and exposure to natural light during the day. Additionally, avoiding bright screens and artificial light in the evening can help to promote the production of the sleep hormone melatonin.

Overall, the body clock plays a crucial role in regulating our daily lives, and understanding and maintaining it can lead to better overall health and well-being.
