Studies have found that people who sleep only four hours a day have much higher blood pressure and a much higher incidence of heart disease than those who sleep eight hours a day. Long-term lack of sleep also increases the risk of stroke, obesity, type 2 diabetes, cancer, dementia and depression.
The first step of health preservation is to follow the laws of nature.
Bai Yan, an expert in qi and blood management, said that whenever it comes to health preservation, many people love to ask, "What should I eat? In fact, health care should be a habit, and cultivating a correct habit that conforms to nature is the first step of health care.
The ancient people's work and rest were based on "work at sunrise and rest at sunset". They get up at dawn and rest at dark. According to the viewpoint of "meridian circulation" in traditional Chinese medicine, it is a time for human cells to rest and innovate from Shihai (9 pm) to Yin Shi (5 am). At this time, people are on the side of the earth's rotation to the back of the sun, and the yin is dominant. Only with enough rest can they have a good physical condition.
With the development of modernization, people sleep more and more late, even upside down day and night. They don't sleep at night and can't get up during the day. Teacher Bai Yan emphasized that people's work and rest deviate from the natural laws of heaven and earth, which is harmful to health. She said: "The sharp increase of hyperlipidemia and fatty liver in modern people is absolutely directly related to sleep; Especially people who often stay up late, work night shifts, or sleep badly are the most common. It is actually very simple to cure these problems, that is, to sleep well at the right time. "
Decompression, anti-aging, good sleep, the more sleep, the healthier.
From the point of view of modern medicine, melatonin is secreted most vigorously from 1 1 in the evening to 1 in the morning, which will promote the secretion of growth hormone, so you should sleep during this time. In addition, sleeping at night 10 to 6 am can regulate the secretion of stress hormone cortisol. In other words, going to bed early and getting up early can eliminate chronic stress.
Our liver is responsible for monitoring the secretion of cortisol, that is to say, if we don't sleep at night, our body will continue to secrete cortisol to cope with stress, and the liver can't rest and relax, which coincides with the view of Chinese medicine that staying up late will hurt the liver.
Long-term late sleep or poor sleep, loss of liver yin, can also cause excessive liver fire and burn the lungs. Weak lung qi deficiency can cause symptoms such as dry cough and expectoration; Skin pores are controlled by the lungs, which not only leads to skin deterioration, but also causes various skin diseases, such as headache, anxiety and boredom.
Teacher Bai Yan emphasized that a good sleep will make people sleep healthier, especially if women don't want premature aging or endocrine disorders, it's best to go to bed early and get up early. It is suggested to do qigong before going to bed to help sleep, which is different from the general exciting exercise that makes people unable to sleep. Qigong focuses on gentle breathing. When the body is relaxed, it is easier for people to fall asleep and sleep better, which is the most important way to invigorate the body.
For example, calming the nerves and helping sleep have a very good effect on improving sleep quality. In a short time, you will find that your sleep is better, your physical strength is increased, and your stress is reduced. Miss Cai insists on practicing for 3 months before going to bed every day, and still has obvious rejuvenation effect. Her complexion has improved, her skin is shiny and she is full of energy.
