To understand what is the correct way to go to bed early and get up early, we need to understand two knowledge points first.
1, what is a healthy sleep?
2. How to define the best sleep time.
A correct understanding of sleep knowledge plays an important role in ensuring sleep health, so everyone must pay attention to sleep.
If you want to explain what sleep is, I think most people will find it easy to understand, but it is actually incomprehensible. Medical textbooks describe sleep in this way: "Sleep means that the brain and physical strength of people are in a relatively stagnant or unresponsive state. At this point, perception is divorced from the external environment, but it can be awakened at any time. This may be due to the inhibition of the brain stem on the awakening impulse of the cerebral cortex, or the special central inhibition caused by the sleep center of the brain. " This is an operational definition of sleep given by doctors.
So, what is sleep? What is sleep health?
The health standard put forward by the World Health Organization is: "A person is sound in four aspects: physical health, mental health, social adaptation health and moral health". These are the four elements of health.
Diet and sleep are that basic guarantee for physical health, mental health and social adaptation. Conversely, physical health, mental health and social adaptation health also have obvious effects on diet, sleep and sexual function. Sleep is something we must do every day. Someone once called it a "sleep bank" figuratively, because it is similar to the rules of a bank, and you have to deposit it to get it.
But the quality of sleep is more important than the length of sleep. If you sleep for five or six hours every day, you can achieve the effect of relaxation and energy, indicating that enough sleep time is not good for your health.
As long as you feel comfortable, you actually meet the requirements of high-quality sleep. Sleep emphasizes quality, not the length of time, which is also the premise of defining healthy sleep.
For normal people, it is necessary to know the best sleep time, which is necessary for good health.
The best sleep time for adults is generally 10 from night to 6: 00 a.m., for the elderly from 9: 00 p.m. to 5: 00 a.m. and for children from 8: 00 p.m. to 6: 00 a.m. It is a habit that human beings have developed since ancient times to work at sunrise and rest at sunset.
The nightlife in modern society is getting richer and richer, and the time for sleeping is getting later and later. Less and less sleep time will have a negative impact on physical and mental health. For example, some people often go to bed early, such as being obsessed with mahjong and even playing all night.
Although I slept again the next day, the disorder of sleep-wake biological clock will lead to sleep disorder, drowsiness during the day, difficulty in concentration, insomnia at night and inability to sleep, which is obviously harmful to physical and mental health.
However, the length of sleep should be appropriate, not the more you sleep, the better.
People who sleep for 7 to 8 hours every night are the best.
People who sleep too long often have symptoms such as difficulty in falling asleep, easy to wake up in the middle of the night, waking up too early, feeling that their physical strength has not been effectively recovered after waking up, and easy to doze off during the day. Those who sleep seven to eight hours a night have fewer sleep problems.
The sleep time needed by the human body is related to the recovery of spirit and physical strength. If you deliberately prolong or shorten the sleep time, it will affect this recovery process and thus fall into a strange circle of sleep uneasiness. It's best not to deliberately change this time. So everyone should know how to sleep, and can't sleep upside down!
