Scientific research has shown that people should sleep with their heads facing north and feet facing south. This is because the earth itself has a geomagnetic field exists, the direction of the geomagnetic field is north-south (divided into the South Pole and the North Pole) magnetic field has the nature of attracting iron, cobalt, nickel, the human body contains these three elements, especially the blood contains a lot of iron (in the red blood cells of hemoglobin), choose the head north feet south orientation to sleep, can comply with the geomagnetic lines of force, so that the magnetic lines of force smoothly through the body, minimize the earth’s magnetic field on the The human body’s interference, so that sleep more sweet. Chinese medicine also believes that people should sleep in a north-south direction, and head north and feet south. The explanation is that by taking this sleeping direction, the direction of Qi and blood running in the human body is consistent with the direction of the Earth’s magnetic lines (i.e., the biological molecules in the human body will change from a chaotic arrangement to a directional arrangement), which makes it easy for Qi and blood to flow smoothly, lowering the metabolic rate and reducing energy consumption, and when you wake up, you will naturally feel good physically and mentally. Head north feet south of the sleeping posture, invariably require us to place the bed in the bedroom, to north-south orientation is appropriate, try not to east-west orientation. This is because of the way the bed facing east and west, will directly cause people to sleep in the east and west, so that it is easy to change the distribution of blood in the body, especially the distribution of blood to the brain, thus causing insomnia or dreamy, reducing the quality of sleep. Many ancient and modern medical doctors believe that both men and women, young and old, lying on the right side, the body is slightly bent is the best sleeping position. This is mainly deduced from the physiological structure of human beings. The human heart is located on the left side of the chest, the opening of the gastrointestinal tract are on the right side, the liver is also located on the right side. If you sleep on the right side, you can reduce the pressure on the heart, the pressure on the heart is small, it is conducive to blood pulsation, increasing the flow of blood supply to the stomach, liver and other organs, at the same time, the right side of the stomach when lying easier to flow into the duodenum and small intestine, thus facilitating the digestion and absorption of food and human metabolism. In addition, the use of this position to sleep, but also to relax the muscles of the whole body in the sleep process, and to ensure smooth breathing, and can make the heart, lungs and gastrointestinal physiological activities to a minimum. Because the heart is not compressed, the lungs breathe freely, so it can ensure the supply of oxygen needed by the whole body in the sleep state, so that the brain gets sufficient rest and improve the quality of sleep. All other sleeping positions have one or another disadvantages. Supine, the tongue root back, easy to make breathing and snoring, after sleep, hands are also easy to put on the chest pressed heart fossa, resulting in nightmares, so that people sleep very “tired”; prone, chest, abdomen pressure, nose and mouth easily covered by pillows, but also easy to cause “pillow “; when lying on the left side, the apical part of the heart is vulnerable to pressure, ear pressed to the pillow can hear the heartbeat, affecting sleep, over time, can also lead to neurasthenia and cardiovascular disease. For most healthy people, in fact, do not have to be overly concerned about their sleep position. This is because during a night’s sleep, the body turns over more times, and it is impossible for people to maintain the same sleeping position until dawn. Our body is very smart, it will always let people in the process of sleep and unconsciously change the sleeping position in order to relieve fatigue and restore strength. For people suffering from certain diseases, it is necessary to talk about the sleep position, not mechanically forced to the right side of the bed. Take some protective sleeping position on their own, to prevent the occurrence of disease or reduce the symptoms of disease are beneficial. It is important to know that many diseases are induced or aggravated by improper sleeping posture. Here we will specifically introduce the appropriate sleeping position for several common diseases 1, tuberculosis: both lungs are sick people, it is best to sleep on your back. If the left lung disease is appropriate to sleep on the left; right lung disease, it is appropriate to sleep on the right. 2, myocarditis, asthma, heart failure: take half lying half sitting sleeping position, can improve the blood circulation of the lungs, reduce pulmonary stasis, increase the amount of oxygen intake, conducive to the relief of symptoms and rest. 3.Otitis media: Generally, the pus will fill the affected ear canal. In order to make the pus drainage smooth, the affected side can be taken to lie down in order to promote the pus discharge. 4.Gastric ulcer: Patients with gastric ulcer should be advocated to lie on the left side. If lying on the right side, the flow of acidic fluid back from the stomach to the esophagus is much more than normal and persistent, which can cause burning pain in the stomach. 5, heart disease: the compensatory function of the heart is still good, can lie to the right. If there has been heart failure, you can use a semi-recumbent position to reduce respiratory distress, do not lie on the left side or prone. 6, hypertension: hypertensive patients, especially the elderly hypertensive patients, sleeping position should be semi-recumbent or side lying, can use a 15 cm high pillow, too high or too low will produce discomfort. 7, cholecystitis, cholelithiasis: it is appropriate to take the right lateral position, which is conducive to the excretion of bile, to prevent stone embedment, obstruction, thereby relieving pain. 8, low back pain: it is appropriate to sleep on the side, so that the muscles can be completely relaxed, to avoid muscle tension, stimulation or compression of nerves, and cause or aggravate low back pain. 9, cervical spondylosis: the pillow should be placed under the neck when sleeping, do not let the neck dangling, and do not suddenly and violently turn over. If you can pillow with cervical spine health pillow naturally better.
