Question

Define the term "circadian rhythm" and the impact on bodily temperature, cortisol secretion, and wake and sleep cycle.

Answer 1

Circardian rhythm is a cycle which regulates such physiological processes in our bodies as sleeping, waking up and eating. It is also known as the "body clock" as it regulates what to do when.

Circardian Rhythm is responsible for the regulation of body temperature when subject to rise and fall. It is also essential for cortisol secretion which is seen the most in the morning after waking up and low when one goes to sleep. Cortisol secretion is essential for the proper functioning of the human body. Otherwise, stress may increase and even lead to death. Finally, circardian rhythm also determines when a person sleeps and for how long and when he or she wakes up.
