Pineal melatonin is a hormone that regulates the body’s daily (circadian) clock and so melatonin is commonly used in human research to understand the body’s biological time. There is a rhythm to the biology of the pineal gland and melatonin is secreted according to the amount of day light a person is exposed to.
Just so, can biological clock affect sleep?
Without the proper signaling from the body’s internal clock, a person can struggle to fall asleep, wake up during the night, or be unable to sleep as long as they want into the morning. Their total sleep can be reduced, and a disrupted circadian rhythm can also mean shallower, fragmented, and lower-quality sleep.

The hypothalamus helps in the production of releasing hormones and regulation of temperature, hunger and thirst. Hypothalamus is located above the pituitary gland and below the thalamus. It regulates endocrine functions through the pituitary gland.
What is the biological clock controlled by?
How does our body clock know what time of day it is? The circadian biological clock is controlled by a part of the brain called the Suprachiasmatic Nucleus (SCN), a group of cells in the hypothalamus that respond to light and dark signals. When our eyes perceive light, our retinas send a signal to our SCN.
What part of brain is biological clock?
In mammals the brain’s circadian clock is manifest in the activity of neurons in a small portion of the hypothalamus, the suprachiasmatic nucleus (SCN).
