The biological clock: Respect the program God created for your body

Help your body, respect your biological clock, conform to the program God has created for your body: “We made your sleep a slumber, and made the night a dress, and made the day a nest.” In humans, this clock is located in an area under the brain's crib gland. It consists of two nuclei each containing about 10,000 neurons that show electrical activity that oscillates over a period of approximately 24 hours. This electrical activity is controlled by periodic expression of about 15 "hour" genes. The most important thing to maintain is the secretion of melatonin: “The hormone of the body clock, which is excreted after the brain converts tryptophan to serotonin and then to melatonin. Social factors and physical activity affect the secretion of melatonin, which is also called the happiness hormone,” and this hormone is subject to the influence of light Melatonin is a hormone that is usually excreted every day. Its production increases at the end of the day shortly before bedtime, which helps to sleep. It reaches its peak secretion between 2 and 4 am. After that, its concentration does not stop declining to become almost non-existent in the early morning, shortly after waking up. The rate of secretion of this hormone is controlled by the internal clock, as it is identical in individuals located in total darkness. However, external light can affect its production. The light perceived by the retina goes directly to the suprachiasmatic nuclei that transmit information to a small gland, mites or pineal gland, which secrete melatonin. Exposure to light at night causes the body clock to be delayed, which in turn delays the production of melatonin and sleep. On the contrary, the light show in the morning will present the clock. — Source: Posted on Dr. Mohamed Bourbab's Facebook page on 2020-12-20 https://www.facebook.com/bourbab.m/posts/pfbid0WXUtQkQqPs8hVCbHGfcpUbacFoT8cS97tsXwFtwQ6BPxYBaSEvqRrN3ZbtbCmGQhl
