Do not sleep 'head east, feet west'? Does it make sense or is it 'pseudoscience'? need to know
Many older generations always correct their children and grandchildren's sleeping positions from time to time, which makes them very boring. They think that the old man is really making a fuss over a molehill. That's because there is an old saying in the countryside that if you can't sleep, your feet face west and east. Many old people believe this, so is there any scientific basis for this statement? Or simple feudal superstition? Let's take a look today!
01 You can't sleep facing west and facing east. Where is the saying?
Many people on the Internet say that it is best to choose the north-south direction for sleep, because the sleep direction corresponds to the north-south magnetic field of the earth, which can correspond to a straight line. The human body is affected by the magnetic field, which is beneficial to the blood circulation of the human body and helps people sleep better. The sleeping direction only passes through the earth's magnetic field. Breaks the balance and, if prolonged, even causes insomnia and dreams.
In addition to being related to the earth's magnetic field, some people say that the east-west direction even violates the direction of the earth's rotation, because the earth's rotation is from west to east, and the sleeping position of head, east, feet, and west will make people's blood surge, which may cause Brain bloating, stomach pain, slow blood circulation and other problems.
02 Are the above two statements correct?
First, we must first understand the Earth's magnetic field. As we all know, the earth we live in is a huge natural magnetic field. Electromagnetic wires disperse from the North Pole and flow into the South Pole through the atmosphere. The human body is also a complex and precise biomagnetic field. When the human body is in a sleep state with feet on the west and east on the east, the biomagnetic field of the human body intersects with the earth's magnetic field to form a strong electromagnetic resistance, which is difficult to eliminate. In addition, when people sleep, they need to continuously obtain energy from the outside to help various tissues and organs in the body to function normally and release energy at the same time. Electromagnetic influence just hinders the way the human body releases energy, so the heat consumed by the human body cannot be dispersed, which can easily lead to elevated body temperature and blood disorder, specifically manifested as headaches, brain swelling, psychological depression, insomnia, dreaminess and other diseases.
But if it is in the north-south direction, the biomagnetic field of the human body is in line with the direction of the earth's magnetic field, the bioelectric current of the human body will be parallel to the entire earth's magnetic field, the biological cells can be active normally, and the normal operation of the organs can be adjusted, which not only helps to improve the blood circulation of the human body, accelerate metabolism, and improve sleep quality. Therefore, the elderly often say that there is a certain scientific basis for not sleeping eastward and westward.
The second is the relationship between the rotation of the earth and the direction of sleep. From the perspective of traditional Chinese medicine, Lao Tzu recorded in the "Tao Te Ching": Man follows the earth, the earth follows the sky, the sky follows the Tao, and the Tao follows nature. This sentence means that the rising and falling laws of human qi and blood are related to the rising and falling laws of water and fire in the five elements of the earth. In other words, various periodic changes in nature will affect the circulation of Qi and blood in people. The law of the earth's rotation is from west to east, and it takes 23:56 minutes and 4 seconds to rotate, which is what everyone calls a day. On this day, the sun and the moon alternate wrongly, and the circulation of qi and blood corresponds to the phases of the sun and the moon. During the day, the blood fluctuates, and at night the deficiency and excess increase and decrease. "Suwen Bazhengshen Theory" also mentioned that the best time to treat the human body's qi, blood and lungs is generally related to seasons and time. Therefore, it is correct that the rotation of the earth has some influence on human sleep.
Generally speaking, the earth's magnetic field and autobiography will indeed have a certain impact on the human body, but it can only be said to be very small. After all, the factors that affect the operation of Qi and blood meridians are not only sleep direction, such as staying up late smoking, drinking, overeating, Different regions will have various effects on health, so we don't have to worry too much about the so-called correct direction and overall layout of the family.
03 What can you do to get enough sleep?
About diet. Common sleep drinks generally refer to milk, because milk contains a lot of tryptophan, which can effectively relieve mental fatigue, calm the brain, and inhibit brain excitement, which is of great benefit to sleep. In addition to milk can help sleep, household vinegar and sugar can also help the brain relieve fatigue. Before going to bed, you can take out a spoonful with a small spoon and put it in warm water to drink. The substances in the vinegar and sugar travel along the bloodstream through the cerebral cortex, helping you get a good night's sleep.
About exercise. Since everyone is busy with work and family and has no extra energy to go to the gym to exercise, it is recommended that you use moderate walking exercises. After scientific research, the best time for people to walk is about 30-40 minutes, and it is recommended to walk after dinner. Effective walking can not only enhance people's cardiopulmonary function, promote blood circulation, but also burn fat in more than 40 minutes, so walking is also a good way of exercise.
about the sleeping environment. Now most people can't play mobile phones for half an hour before going to bed. Some people may think about saving electricity bills and turning off the lights to play with mobile phones, but in fact, this approach is not correct. Turning off the light and playing with mobile phones will not only cause damage to the eyes, but also affect the function of the cervical spine and disrupt the quality of sleep. Long-term decline will also reduce the body's immunity and increase the possibility of cardiovascular disease. Here, it is recommended that when you lie down and play with your mobile phone, you can put a natural light lamp on the bedside, and you only need to adapt to the light when you sleep.
If you want to have a good sleep quality, good living and eating habits are the key. Sleep will have a slight impact on the body, which is negligible, so we should also have our own judgment ability, truly identify all kinds of network information, and follow the doctor's advice. After all, it is best for us.
