Circadian rhythms are regulated by the suprachiasmatic nucleus (SCN) in the brain, located in the hypothalamus. The SCN receives input from light-sensitive cells in the retina, helping to synchronize internal body clocks with the external environment.
Melatonin
Pineal gland is involved in adjustment to biological clock. It is located on the dorsal aspect of the brain. It get frequently ossified. Once you are adjusted to biological clock, then it is not needed probably.
Melatonin is the hormone that is involved in the rhythmic activities. The melatonin hormone is secreted by the pineal gland that plays a central role in the coordination of the circadian system and circadian rhythms.
Exposure to red spectrum light can disrupt human circadian rhythms by suppressing the production of melatonin, a hormone that helps regulate sleep-wake cycles. This can lead to difficulty falling asleep and can disrupt the body's natural sleep patterns.
Melatonin is a hormone that helps regulate sleep patterns and circadian rhythms. It is produced by the pineal gland in the brain and is released in response to darkness, signaling to the body that it is time to sleep. Melatonin levels typically rise in the evening and peak during the night, promoting sleep. This hormone plays a crucial role in maintaining the body's internal clock and ensuring a healthy sleep-wake cycle.

Melatonin is a hormone primarily produced by the pineal gland in the brain that helps regulate sleep-wake cycles. It is not an enzyme, but rather a signaling molecule that plays a key role in controlling circadian rhythms and promoting sleep.
