People who sleep too much will feel dizzy and weak. Too much sleep will endanger human health and cause insomnia.
When people sleep, most of the blood will flow to digestive organs such as gastrointestinal tract, while the brain is at rest, so the blood will be less. For example, people will feel dizzy and weak after eating at noon, because most of the blood will flow to digestive organs such as gastrointestinal tract. You said that if you sleep too long, you will feel dizzy, which is why if you sleep too long, your brain will have less blood supply for a long time and will be relatively oxygenated. You will also feel dizzy. Of course, it is also related to the environment in which you sleep, such as whether the air is circulating, whether the environment is quiet, and whether the quality of sleep is good. There is a limit to everything. The average person can sleep for about 8 hours, not as much as possible. This may also be the embodiment of dialectics.
Kate Fox, a British social expert, said that for most people, lack of sleep the night before means drowsiness and anxiety the next day. Now there are two diametrically opposed views. One is that people generally lack sleep, so their physical and mental health is being damaged to varying degrees, and the incidence of hypertension, coronary heart disease, heart disease, stroke, diabetes and obesity has greatly increased; On the other hand, only a few adults need at least 8 hours of sleep, and they are always worried that lack of sleep will lead to habitual insomnia. A survey published last year showed that people actually don't need as much sleep as we thought. Too much sleep will actually harm our health, which is the chief culprit of insomnia. Researchers from the University of California, San Diego and the American Cancer Society have investigated the sleep habits of more than 654.38 million+00,000 Americans in the past six years. They found that people who usually sleep six to seven hours a night (which is also the sleeping situation of most people) live longer than those who sleep at least eight hours a night. Studies have shown that people who sleep the longest can increase their death probability by 15% at most. Even people who sleep for only five hours live longer than those who sleep for eight hours according to the usual health standards. In addition, it is generally believed that women are more sleepy, but the survey results show that women live longer than men under the same conditions of less sleep time. In short, both men and women have an unchanging conclusion: the longer they sleep, the greater the probability of death.
Trying to use drugs to prolong sleep time is particularly dangerous. People who claim insomnia often live as long as healthy people, while those who regularly take sleeping pills have a high probability of premature death of 25%. It can be seen that taking sleeping pills to prolong sleep time is not beneficial to human health.
Of course, real lack of sleep does have a negative impact on the human immune system. However, more and more experts engaged in the study of sleep problems believe that the public's excessive concern about lack of sleep is a double-edged sword, with both advantages and disadvantages. Even if you really think you need more sleep, the latest advice to improve your sleep quality is to drive away as much sleep as possible and keep yourself awake. This view seems ridiculous to the extreme, but if you stop trying to put yourself to sleep and try to stay awake and stop worrying about lack of sleep all day, you will find that the sleep system controlled by the brain is fully capable of automatically adapting to your sleep situation.
1, the best sleep time is 9- 10 at night, because from a scientific point of view, it is just before the arrival of biological low tide (according to the determination, biological low tide appears before10-1pm). If you can follow the rules, you can have a good sleep.
2. The average adult sleeps for 6-7 hours. After this period of time, the mind and body will automatically repair and reach the best state.
3. 5-6 am every day is the first climax of the biological clock in a day, and it is the most appropriate time to get up.
Second: lunch break is very important.
Lunch break is very important for human health. A proper lunch break can relieve fatigue and restore energy and physical fitness. It can also reduce the occurrence of diseases such as cerebral hemorrhage and coronary heart disease. It should be noted that the lunch break posture should be correct, generally lying flat for half an hour to 1 hour, so that the muscles of the whole body can be relaxed and the energy can be restored.
Third: stay in bed for 3 minutes.
After waking up, lying in bed for 2-3 minutes can complete the conversion and alternation of biological clock activities under different static and dynamic conditions. Conducive to the relative acceleration of activities of limbs, muscles and organs, and prepare for activities after getting up. But stay in bed for too long.
