sun simiao
Sun Simiao, a medical scientist in the Tang Dynasty, was praised as the "King of Medicine" by later generations. He is also a Taoist figure with a high status. There are "Wang Yaotang" in many Taoist temples. He has a noble medical ethics, attaches importance to health preservation and helps others.
Sun Simiao 100 is still healthy, and he can write a book because he has a set of methods of physical and mental conditioning, including his rich thoughts on healthy sleep. Sun Simiao said in the book: "Don't sing if you want to sleep. This is a bad omen. Don't make a fire near your head, it will cause long-term anger. Your head is heavy, your eyes are red and your nose is dry. I don't have to lie down in summer. I have a thick skin and feel tinea. Live long without covering your head at night. Don't lie on the wall, the wind will drive you crazy and make you heavier. "
"If you want to sleep, don't sing. This is an ominous sign. "
What does this sentence mean? Many readers like to hum a song before going to bed, but Sun Simiao thinks it is not good for sleep. Because this kind of singing entertainment will make people more excited. It is the protective response of brain nerve cells from excitement to inhibition during sleep. If you are too excited before going to bed, it will inevitably affect the inhibition process, which is manifested as difficulty in falling asleep or dreaming after sleeping, so that the brain can not get enough rest. So you can't create excitement half an hour before going to bed, you can't sing loudly, you can stop entertainment as soon as possible, and you can't watch TV or movies too late. Similarly, students should not read books or use their brains before going to bed. They should try to avoid thinking about difficult problems, listening to thrilling stories, worrying about other things or dreaming, so as not to keep the cerebral cortex excited. In addition, environmental factors that are not conducive to falling asleep, such as noise, lighting, noise or vibration, should be excluded.
"Don't put a stove beside your head. Over time, it will lead to anger, heavy head, red eyes and dry nose."
The ancients needed stoves to keep warm. Sun Simiao believes that if a person sleeps with a stove beside his head, his head and body will be sleepy, his eyes will be red and dry, and even his nose will be dry after a long time. Although many people don't use stoves to keep warm at home now, this tip is still useful. Because many people like to put oil slices on the bedside when they sleep in cold season, although it is warm, the temperature is a bit high. From the point of view of human comfort, it is most appropriate to control the indoor temperature between 18~20 in winter. Because people wear a lot of clothes in winter, if the indoor temperature is higher than 20, they will feel a little hot. If the air conditioning temperature is set above 26 in winter, or the temperature generated by oil exceeds this value, the indoor air will be extremely dry, which will harm people's yin and body fluids, make people feel hot and dry all over, and dry eyes, nose, mouth and throat, thus reducing the quality of sleep and damaging their health. From the perspective of health care, when sleeping in winter, besides being careful not to put it on your head, you should pay attention to at least two problems. First, the temperature difference between indoor and outdoor should not be too large, and it is advisable to keep indoor 8 higher than outdoor. If the temperature difference between indoor and outdoor is too large, people can easily catch a cold in a sudden hot environment. For the elderly and hypertensive patients, the indoor and outdoor temperature difference should not be too large, because the indoor temperature is too high, which will relax the human blood vessels. If you go outdoors suddenly, the blood vessels will suddenly contract, which will hinder the cerebral blood circulation of the elderly and hypertensive patients and easily induce a stroke; Secondly, the doors and windows are closed when the oil is opened, which will lead to long-term indoor hypoxia and a large number of bacteria and viruses accumulate. Therefore, oil supply should be stopped.
Many readers and friends will feel strange after reading this sentence. Can't they show up to sleep in summer? How can sleeping be "thick-skinned, ringworm-like, or superficial"? Since Sun Simiao is honored as the King of Medicine, he will never be unworthy of his name. "Lying naked" here does not mean that you can't sleep with your face exposed, but that you can't sleep with your body exposed. For example, in summer, many people like to blow air conditioners and fans with bare arms, but even sleeping in the yard is not suitable, because it will be invaded by common cold. When we sleep, our pores are relaxed. Think about it. If our skin "city gate" is opened, will the cold wind directly invade our bodies? Will it increase the probability of beriberi and facial paralysis? "If you don't cover your head in winter, you will live a long life" means that when you sleep in winter, don't cover your head with a quilt or sleep with a quilt, so you can live a long life. Why do you say that? Due to the low oxygen content in the bed, there are many exhaust gases such as carbon dioxide, which will affect the normal respiratory movement, easily induce cardiovascular and cerebrovascular diseases, and even cause suffocation, especially for middle-aged and elderly people.
"Don't lie against the wall, the wind will blow people, make you crazy and make you fat."
The main meaning of this sentence is to remind you not to sleep against the wall! Many families put their beds against the wall. Everyone thinks it saves space and won't fall off the bed when sleeping. However, experts believe that sleeping too close to the wall is actually harmful to health. The best distance between the bed and the wall is more than 20 cm. Because the temperature of the wall can differ from the room temperature by 3~8, if there is no distance of more than 20cm in the middle, or there is no barrier of wooden materials, the cold of the wall is likely to induce some diseases, such as arthritis, rheumatism, rheumatoid, dysmenorrhea, and even serious cardiovascular and cerebrovascular diseases and digestive tract diseases. Especially in summer, sleeping against the wall is more harmful, because people's pores are open at this time, and sleeping against the wall for a long time is more affected by cold, which will greatly increase the probability of various diseases. In addition, if the wall next to the bed is a neighbor's TV wall, it will cause radiation hazard. Generally speaking, the bed and wall should be kept above 20cm, and movable passages should be set aside on both sides of the bed to facilitate access to the bed, so that the moisture in the bedding can be distributed more easily.
