The homeostatic factor regulates the transition from wakefulness to sleep and from sleep back to wakefulness. The homeostatic factors are called the sleep balance and the circadian factor, which is also called the circadian rhythm or the body’s biological clock.
The sleep balance helps to regulate your need for sleep and the depth of sleep you need such that if you do not get enough sleep, you get an increased proportion of deep sleep. Moreover, if you sleep during the day, it can affect your sleep balance to the extent that you find it difficult to fall asleep during the night until you regain your sleep balance.
The body’s biological clock regulates the time and duration of sleep. However, your habits and behavior greatly influence this biological clock. The biological clock also controls various physiological processes such as hormone secretion and body temperature.
Factors Affecting The Body Biological Clock:
Light: This affects the body’s biological clock by affecting the retina of the eye.
Time: During the dark hours of the day, the secretion of melatonin from the brain is important in inducing sleep.
Why Should You Sleep?
Several studies show that the most important function of sleep is to maintain brain function. It has been shown that sleep deprivation leads to impaired memory and impaired responsiveness. Sleep is also of great importance for your physiological and mental reconstruction after illness and operation.
Sleep is needed for rebuilding the body cells and tissues. It is important for the immune system, the secretion of vital hormones, and body temperature regulation. Sleep also causes changes in the autonomic nervous system. It affects blood pressure, pulse rate, and respiration.
To get the best sleep cycle, you must have control over the sleep balance and circadian rhythm.
