About Sleep

The exact definition of sleep has different connotations as the times change. Initially, French scholars believed that sleep is a state in which sensory and motor activities are temporarily stopped due to the body's internal needs, and that appropriate stimulation can cause immediate awakening.

Later, people became aware of brain electrical activity and believed that sleep was a low level of physiological activity in animals caused by the functional activities of the brain, and that appropriate stimulation could bring them into a state of complete wakefulness. After years of research, modern medicine generally believes that sleep is an active process. Sleep is the rest necessary to restore energy and is beneficial to mental and physical recovery. Proper sleep is the best rest. It is not only the basis for maintaining health and physical strength, but also the guarantee for achieving high productivity.

Deep sleep meaning

Experiments have shown that even a short-term lack of sleep or lack of sufficient sleep time can cause the human body to age rapidly and significantly reduce immunity. Deep sleep at night, through the action of the hypothalamic nerve center, actually regulates the metabolic activities of various tissue cells to affect the physiological activities of the human body. It is mainly used to repair cell damage and restore the integrity of tissue function. The biological clock is controlled by the suprachiasmatic nucleus (SCN) in the hypothalamus of the brain, which sends "time signals" to the central nervous system through the secretion cycle of endocrine hormones, thereby affecting the body's time biological effects. This means that the body's repair mechanism must be carried out at night.
