Is it superstitious to say “you can’t sleep with your feet facing west”? The doctor teaches you how to have a good sleep

Sleep is a major event in life, every day to ensure enough sleep, in order to ensure energy. There are also many people who love to sleep very much. As long as they have a holiday, they can lie in bed for a day and eat without getting out of bed. There are many folk sayings in China. Old people often come here with their mouths open. I wonder if you’ve ever heard such a saying: “you can’t sleep with your feet facing west.”. < / P > < p > why is there such a saying? Many old people may not be able to explain themselves. They are slang words handed down from mouth to mouth, and they may not know what it means. Today, I’d like to explain to you that in ancient times, there was a saying that people drove the crane to the west, which is a kind of honorific name for people’s death. Therefore, if they sleep with their feet facing the west, the ancients were superstitious. In this way, they might drive the crane to the west when they sleep. < / P > < p > this is a superstitious saying. Anyway, it sounds a little unreliable. However, there is a scientific explanation, which is quite interesting. We all know that the earth has magnetic fields and magnetic induction lines, and is divided into North and south poles. There is also a magnetic field in the body. From the perspective of the human body, sleeping in the north-south direction can reduce the influence of magnetic induction line on the body, which is more conducive to our sleep. There is a certain reason. < / P > < p > generally speaking, sleeping is a very important thing. You must go to bed in the right way. Here, the doctor will teach you how to get a good sleep. < / P > < p > first of all, if the human body is viewed from the side, it’s not straight, it’s s S-shaped, the belly is convex, and the hips are convex, forming a big s. Therefore, the most correct sleeping position is to sleep side by side, and the left side of the body is the best. According to relevant statistics, 65% of the people are used to sleeping on their side, one third are used to sleeping on their back, and a few are used to sleeping on their stomach. The first two sleeping positions are relatively healthy, and the last one is more harmful to the body. < / P > < p > let’s take a look at prone sleep, that is, sleep on your stomach. Long term prone sleep will increase the curvature of the lumbar spine, and a small joint on the spine is easy to be crushed by this kind of pressure. In addition, in such a sleeping position, most of the weight of the body is pressed on the ribs and internal organs, which may compress the lungs and cause dyspnea. Therefore, many people in this position wake up with backache, dizziness and tiredness. This is caused by improper sleeping position. < / P > < p > therefore, sleeping on the side is a better sleep method, which helps to improve the quality of sleep. Why is side sleeping a better position? Lateral lying is also divided into left lying and right lying, the correct sleeping posture should be right lying, legs slightly curved. This advantage is that the heart is in a high position, unlike the left side lying is oppressed, the liver is in a low position, which is conducive to its blood supply and improve its metabolic efficiency. At this time, the stomach food enters the duodenum due to gravity, which is also conducive to the digestion of food. In addition, the posture itself is easier to relax, the lungs will not be oppressed, and the breathing is relatively smooth. At the same time, the oxygen supply is sufficient, and all organs and cells of the body get a good rest. < / P > < p > however, the sleeping posture is not invariable, and it is a good choice to sleep with various postures changing, which can also prevent muscle stiffness and better relieve fatigue.
