Which direction is the best way to sleep? sleep
Scientific research shows that when people sleep, they should use the direction of the head north and the foot south. This is because the earth itself has a geomagnetic field. The direction of the geomagnetic field is north-south (divided into south and north poles). The magnetic field has the properties of attracting iron, cobalt, and nickel. The human body contains these three elements, especially the blood contains a large amount of iron (in the hemoglobin of red blood cells). Selecting the head north and foot south to fall asleep can conform to the magnetic field lines of the earth, so that the magnetic field lines pass through the human body smoothly, minimizing the interference of the earth's magnetic field on the human body and making sleep sweeter.
Chinese medicine also believes that people should sleep in a north-south direction, with their head north and feet south. The explanation is that if you take this sleeping direction, the direction of qi and blood in the human body is consistent with the direction of the earth's magnetic field lines (that is, the biomolecules in the human body will change from a messy arrangement to a directional arrangement), which makes it easy to make qi and blood smooth, reduce metabolic rate, and reduce energy consumption. When you wake up, you will naturally feel refreshed physically and mentally.
The sleeping position of the head north and the foot south virtually requires us to place the bed in the bedroom with a north-south orientation, and try not to face east-west. This is because the way the bed is arranged in an east-west orientation will directly cause people to face east-west when sleeping. As a result, it is easy to change the distribution of blood in the human body, especially the blood distribution in the brain, which can cause insomnia or dreaminess and reduce sleep quality.
Many medical scientists in ancient and modern times believe that lying on the right side and slightly bending the body is the best sleeping position for both men, women and children. This is mainly derived from the human physiological structure. The human heart is located on the left side of the chest cavity, the opening of the gastrointestinal tract is on the right side, and the liver is also on the right side. If you lie on the right side, you can reduce the pressure on the heart. When the pressure on the heart is small, it is conducive to blood outflow and increase the blood supply to the stomach, liver and other organs. At the same time, when lying on the right side, the stomach contents are easier to flow into the duodenum and small intestine, which is conducive to the digestion and absorption of food and the metabolism of the human body.
In addition, sleeping in this position can also relax the muscles of the whole body during sleep, ensure smooth breathing, and minimize the physiological activities of the heart, lungs and stomach. Since the heart is not compressed and the lungs breathe freely, it can ensure the oxygen supply needed by the whole body during sleep, so that the brain can be fully rested and improve sleep quality.
Other sleeping positions have one or another drawback. When lying on the back, the base of the tongue falls back, which can easily make breathing difficult and make snoring sounds. After sleeping, it is easy to put both hands on the chest to press the heart socket, resulting in nightmares and making people sleep very "tired"; when lying on the stomach, the chest and abdomen are under pressure, the mouth and nose are easily covered by pillows, and it is also easy to cause "stiff pillow"; when lying on the left side, the apex of the heart is easily compressed, and the ear is attached to the pillow to hear the beating of heart sounds, which affects sleep. Over time, it can also lead to neurasthenia and cardiovascular diseases
For most healthy people, there is actually no need to worry too much about their sleeping position. This is because during a night of sleep, the human body flips a lot, and it is impossible for people to maintain the same sleeping position until dawn. Our body is very smart, and in order to relieve fatigue and restore physical strength, it always makes people change their sleeping position unconsciously during sleep.
For people with certain diseases, it is necessary to pay attention to the sleeping position and not mechanically force the right side of the bed. Adopting some protective sleeping positions on your own is beneficial for preventing the occurrence of diseases or alleviating the symptoms of diseases. You know, many diseases are caused or aggravated by improper sleeping positions.
The correct sleeping position
1. Patients with heart disease: avoid lying on the left side or prone
Those with good cardiac compensatory function can lie on the right side. If heart failure has occurred, a semi-recumbent position can be used to reduce breathing difficulties.
2. Cerebral thrombosis:
If arteriosclerosis adopts the side lying position, it will inevitably aggravate the blood flow disorder, and it is advisable to change to the supine sleeping position.
3. Pulmonary diseases:
For people with diseased lungs on both sides, it is best to sleep on your back. If the left lung is diseased, it is suitable to sleep on the left side; if the right lung is diseased, it is appropriate to sleep on the right side.
4. High blood pressure:
In particular, elderly patients with hypertension should sleep in a semi-recumbent or side position, and use a rectangular pillow to place their head and shoulders on.
5. Cholelithiasis: It is not advisable to lie on the left side
Because the gallbladder is located in the upper abdomen and is shaped like a small wine bottle. When the human body lies on the left side, the gallbladder "bottle mouth" faces down and the "bottle bottom" faces up. In this way, gallbladder stones can easily fall into the "bottle neck" under the action of gravity and become incarcerated, causing biliary colic attacks. Therefore, you should sleep on your back or on your right side as much as possible.
6. Low back pain:
It is recommended to sleep on your side, which can completely relax the muscles and avoid muscle tension, irritation or compression of nerves, causing or aggravating low back pain.
7. Otitis media:
The pus will fill the ear canal of the affected side. In order to make the pus drainage smooth, the affected side can be taken to lie down to promote the discharge of pus.
