Don't sleep 'head east, feet west'? Does it make sense or is it 'pseudoscience'? need to know
Many of the older generation are always correcting their children and grandchildren's sleeping positions from time to time, which makes them very bored. They think the elderly are really making a fuss. That's because there is an old saying in the countryside that you can't sleep without your feet facing west and facing 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 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 and can correspond to a straight line. The human body is affected by the magnetic field, which is conducive to human blood circulation and helps people sleep better. Upsetting the balance, if prolonged, even leads to insomnia and dreams.
In addition to being related to the earth's magnetic field, some people say that the east-west direction even goes against the direction of the earth's rotation, because the earth's rotation is from west to east, and the sleeping position of the head, east, feet, and west will make people's blood surge, which may cause Brain bloating, stomach pain, slow blood circulation, etc.
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 lines scatter from the North Pole and flow through the atmosphere to the South Pole, and the human body is also a complex and precise biomagnetic field. When the human body is in a state of sleep, the biomagnetic field of the human body is interspersed with the earth's magnetic field, which will 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 of the body function normally, and release energy at the same time. Electromagnetic influence just hinders the way the human body releases energy. Therefore, the heat consumed by the human body cannot be dispersed, which can easily lead to increased body temperature and disorders of qi and blood. The specific manifestations are headache, brain swelling, mental depression, insomnia, dreams and other diseases.
However, 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, and the bioelectric current of the human body will be parallel to the entire earth's magnetic field. quality. Therefore, the elderly often say that there is a certain scientific basis for sleeping not to face east and west.
The second is the relationship between the Earth's rotation and the direction of sleep. From the perspective of traditional Chinese medicine, Lao Tzu states in the Tao Te Ching that people follow earth, earth follows heaven, heaven follows Tao, and Tao follows nature. The meaning of this sentence is that the rising and falling laws of human qi and blood are related to the rising and falling laws of water and fire of the five elements of the earth. In other words, various cyclical changes in nature will affect the circulation of Qi and blood. 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 are alternately wrong, and the circulation of qi and blood corresponds to the appearance of the sun and the moon. During the day, blood fluctuates, and at night, the amount of blood increases and decreases. It is also mentioned in "The Theory of the Eight True Gods" that the best time to treat the qi, blood and lungs of the human body is generally related to the season and time. Therefore, it is correct that the earth's rotation has a certain effect on human sleep.
Generally speaking, the earth's magnetic field and autobiography do 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 the blood meridians are not only the direction of sleep, such as staying up late smoking, drinking alcohol, overeating, Different regions can have various effects on health, so we don't have to worry too much about the so-called right direction and overall home layout.
03 In order to get enough sleep, what can you do?
About diet. Common sleep drinks generally refer to milk, because milk contains a lot of tryptophan, which can effectively relieve mental fatigue, soothe the brain, inhibit brain excitement, and be of great benefit to sleep. In addition to milk that can help with sleep, household vinegar and sugar can also help the brain relieve fatigue. You can take a spoonful with a small spoon and put it in warm water to drink before going to bed. The substances in vinegar and sugar travel along the bloodstream through the cerebral cortex to help you get a good night's sleep.
About exercise. Since everyone is so busy with work and home that they don't have the extra energy to go to the gym, it is recommended that you use a moderate walking workout. 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 to exercise.
about the sleeping environment. Most people these days can't play their phone for half an hour before going to bed. Some people may consider saving electricity bills and playing with their phones by turning off the lights, but in fact, this practice is not correct. Turning off the lights 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 also reduces the body's immunity and increases the likelihood of cardiovascular disease. Here, it is recommended that when you lie down and play with your mobile phone, you can put a natural light on the bedside, and you only need to adapt to the light when you sleep.
Good living and eating habits are key if you want to have a good sleep quality. Sleeping will have a slight impact on the body, which can be ignored, so we should also have our own judgment ability, truly identify various network information, and follow the doctor's advice. After all, it is best for us.
