What is biological sleep?

Sleep mechanisms Your body’s biological clock, which is based on a roughly 24-hour day, controls most circadian rhythms. Circadian rhythms synchronize with environmental cues (light, temperature) about the actual time of day, but they continue even in the absence of cues.

What is your sleep rhythm driven 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 is meant by biological rhythms?

Biological rhythm is a phrase often used interchangeably with circadian rhythm. These rhythms are a series of bodily functions regulated by your internal clock. They control cycles like sleep and wakefulness, body temperature, hormone secretion, and more.

What is biological clock PPT?
