For most people, they should lie on their backs. When lying on your back, all the muscles in your back are relaxed and your neck is relaxed. There is no excessive pressure, but there is a key premise: the pillow is facing the pillow. A good pillow has nothing to do with the price of natural fillers, new materials and new materials. The key is to see the width and height of the pillow. The width should be shoulder-width, the pillow should be mainly placed under the neck, and the height of the pillow should be similar to that of the fist. If you have a friend, you have long been used to pillows without pillows, pillows with low pillows or pillows with high pillows. Do you feel comfortable? Maybe your neck is a little deformed in silence.

Ordinary people refer to people with relatively standard height and weight. A more scientific sleeping position is lying on the right side with legs slightly bent. In this way, the heart position is high, it is not oppressed, the liver position is low, the blood supply is good, and it is beneficial to metabolism. Food in the stomach is pushed to the duodenum by gravity, which can promote digestion and absorption.

Fat people are more suitable for sleeping on their backs. Their huge bodies are scattered on their broad backs, and the pressure on each part is light, so they can sleep for a long time. If fat people want to sleep on the side of ordinary people, being overweight will oppress the other half of the body and oppress organs such as the heart and internal organs for a long time, which is not conducive to their health. It is generally believed that supine, back and hands and feet straight is the best way to sleep. Generally speaking, the most relaxed sleeping position is lying on the left. When lying on the left side, your legs are slightly bent, and your body can completely prevent loosening. However, it is not advisable to lie on the left side for a long time, so as not to squeeze the heart, and it is also easy to oppress the gastrointestinal tract and slow down the gastric emptying. Lumbar disc herniation is generally suitable in supine position and lateral position.
