More than one-third of one's lifetime is spent in morpheus, and need to keep the right amount of sleep daily, otherwise, people are prone to physical or mental illness, this means that is how important sleep is for people.
Sleep is also the most important, periodic physiological process in a limited life.Why is sleep so important to life?Here's how important sleep is.
After observation, sleep may have six functions:
(1)Promote brain function growth and development. It is mainly related to REM sleep. REM sleep is still active in the brain, and the brain is still in the process of integrating information from various memories, constantly adjusting the connections between the brain's nervous system.
(2)Conserve brain and body energy. It is mainly related to REM sleep. NREM sleep is a relatively quiet stage in the brain and body, with a significant decrease in total body metabolism, especially in the deep sleep period, the pulse slows down, drop 10 to 30 times per minute, and the breathing becomes slower and slower. Basal metabolic rate and brain metabolism decreased by 10-15%, blood pressure decreased by 10-30mmhg, brain blood flow decreased by 25%, and the amount of nutrients in the brain increased significantly. Therefore, sleep preserves the brain's energy and allows the body to recover.
(3)Consolidate memories and ensure that the brain works best. If sleep deprivation or sleep deprivation can cause attention and memory loss, it's easy to forget what you already remember. In the event of a car accident, the U.S. space shuttle challenger, and the three mile island nuclear power plant accident, it was related to insufficient sleep and lack of response.
(4)Strengthen the body's immune system
During sleep, the body can regulate the production of more immune cells and substances, which are beneficial to the human body against disease.
On the contrary, lack of sleep or sleep disorders can also lead to immune disorders, leading to the occurrence and development of diseases.
(5)Promote body growth and delay aging
Most of the growth hormone is produced in the deep stage, but the growth hormone promoting body growth and slow the aging of the material, so sleep can promote growth and slow the aging, in fact, many patients with chronic insomnia often appear the phenomenon of premature aging, is also a kind of validation.
(6)Protect the central nervous system
During sleep, the blood-brain barrier is weakened, preventing harmful substances from entering the brain and protecting the central nervous system.
