1, people who can sleep can live longer.
Traditional Chinese medicine has always attached importance to sleep and health preservation, believing that "sleeping and eating are important tasks of health preservation" and "those who can sleep and eat can live forever". There is a cloud in Li Yu's Collected Works of Li Weng in the Qing Dynasty: "The key to health preservation is to sleep first. Sleep can restore essence, nourish qi, strengthen spleen and stomach, and strengthen bones and muscles. "
Two American scholars have studied 7000 people for five and a half years. They think that there are seven reasons that can affect people's life span, the most important of which is sleep.
Modern medical research shows that energy can be accumulated again after sleep, which can compensate the energy consumed in one day's activities and reserve new energy for the next day's activities.
A good sleep can eliminate general fatigue, rest brain nerves, endocrine, substance metabolism, cardiovascular activities, digestive function and respiratory function, promote the growth and self-repair of body tissues, enhance immune function and improve resistance to diseases, which is very important for health preservation.
2. What habits make you sleep well?
1, sleeping as a child is the most nourishing yin.
It is suggested to rest at midnight (9: 00 ~ 1 1: 00) and go to sleep at midnight (11:00). Chinese medicine believes that when Yin Qi is strong, you will fall asleep, but when Yang Qi is strong, you will wake up. Children are when the yang is the weakest and the yin is the most prosperous. At this time, sleeping is the best way to nourish yin and the quality of sleep is also the best.
It is best to get up at 5 o'clock in the morning, which is helpful for the generation of yang. If you go to bed late the night before, you have to get up before 5 am, and you can take a nap during the day.
2. The effect of sleeping like a bow is good.
"Sleeping like a bow" can reduce the force of the center of the earth on the human body and make people feel relaxed and comfortable. Because people's hearts are mostly on the left side of the body, lying to the right side can reduce the pressure on the heart.
People who love snoring are also suitable for bow sleeping position, because snoring is prone to apnea. If you take the supine position, small tongue will fall backwards, which will easily lead to airway collapse, leading to poor airway circulation and aggravating snoring symptoms.
3, the bedroom can gather yang.
When choosing the orientation of the living house, you should try to choose the house facing south. The sunlight of the house should not be blocked by the building in front, and try to avoid the cold and humid room, which is beneficial to joint health. In addition, for the elderly, it is suggested that the sleeping room should not be too big, mainly in Juyang.
Traditional health care pays attention to closing doors and windows when sleeping, because people will form a protective layer of yang on their body surface when they fall asleep, and ventilation at night will easily blow away the yang. It is recommended to take a bath before going to bed, or turn on the air conditioner in advance to cool the bedroom, but close the window and wear pajamas when sleeping.
4, sleep orientation is particular.
Sun Simiao, a famous medical scientist in the Tang Dynasty, mentioned in Qian Jin Fang that "mortals lie down, facing east in spring and summer, and facing west in autumn and winter". In other words, spring and summer belong to the sun, and the head should lie east; It is cloudy in autumn and winter, and the head should lie facing west, in order to conform to the principle of "nourishing yang in spring and summer and nourishing yin in autumn and winter".
5, eat too much, sleep well
If you eat too much for dinner, you will consume more gas. If you consume gas, you will get angry and disturb the yang. Lack of yang at night may lead to indigestion, food accumulates in the stomach, which will be converted into heat when it is suppressed for a long time, which is easy to produce stomach heat, so it is difficult to sleep well and affect the quality of sleep.
In addition, overeating at dinner will increase the burden on the gastrointestinal tract, and the information of intense work will be continuously transmitted to the brain, causing insomnia and dreaminess, which will easily lead to neurasthenia and other diseases over time.
If middle-aged and elderly people overeat for a long time and repeatedly stimulate a large amount of insulin secretion, it will often cause the burden of insulin B cells to increase, leading to failure and inducing diabetes.
3. Precautions before going to bed
First, avoid eating before going to bed: after people fall asleep, the rhythm of some activities in the body slows down and enters a state of rest.
If you eat before going to bed, your stomach will be busy again, which will increase their burden, and other parts of your body will not get a good rest, which will not only affect your sleep, but also damage your health.
Second, avoid talking before going to bed: because talking too much will make the brain excited and active, making it difficult for people to fall asleep.
Third, avoid excessive brain use before going to bed: If you have the habit of working and studying at night, you should finish the more nerve-racking things in advance and do something easier to relax your brain before going to bed, so that you can easily fall asleep. Otherwise, the brain is in a state of excitement, and it is difficult to fall asleep even when lying in bed. After a long time, it is easy to lose sleep.
Fourth, avoid emotional excitement before going to bed: people's emotions can easily cause excitement or disorder in the nerve center, making it difficult for people to fall asleep and even cause insomnia. Therefore, before going to bed, you should try to avoid being overjoyed or worried about anger, so as to stabilize your mood.
5. Avoid drinking strong tea and coffee before going to bed: Both strong tea and coffee are stimulating drinks, which contain substances that can make people excited, such as caffeine, and it is easy to fall asleep after drinking before going to bed.
6. Avoid sleeping with your mouth open: When sleeping with your mouth open, viruses and bacteria in the air can easily take advantage of it, causing "illness from the mouth", and the lungs and stomach are also easily stimulated by cold air and dust, causing diseases.
Seven, avoid sleeping with your head covered: Old people are generally afraid of cold, so some old people like to sleep with their heads covered. In this way, because of inhaling a lot of carbon dioxide exhaled by oneself and lacking the necessary oxygen supplement, it is extremely harmful to the body.
Eight, avoid sleeping on your back: sleeping posture, lying to the right side is the best, so that the whole body bones and muscles are in a natural state of relaxation, easy to fall asleep, and easy to eliminate fatigue. Lying on your back makes the bones and muscles of the whole body still tense, which is not conducive to eliminating fatigue, and it is also easy to cause nightmares caused by putting your hands on your chest, which affects the quality of sleep.
Nine, avoid sleeping under the light: when people sleep, although their eyes are closed, they can still feel bright. Sleeping in front of the light is easy to make people uneasy, it is difficult to fall asleep, and even if they fall asleep, they are easy to wake up.
Avoid sleeping when the wind is strong: keep the air circulating indoors, but don't let the wind blow directly on your body. Because people's adaptability to the external environment is reduced after falling asleep, if they sleep in the wind for a long time, cold air will invade the body, causing diseases such as colds and chills.
