1. Hip and knee joint diseases: Hip and knee joint will be pulled when lying in mixed position. If there are hip and knee joint diseases, such as arthritis and synovitis, it may cause additional traction or compression on the damaged joints, further aggravating discomfort. Therefore, such people should try to avoid mixed lying.

2. Acute waist injury: For people with acute waist injury, mixed lying position may lead to excessive stretching of waist muscles, thus aggravating the existing injuries. Therefore, this kind of people should avoid taking a mixed lying posture.

Although it is beneficial to harmonize qi and blood and relax muscles and bones, it is not suitable for everyone. If you have any related health problems, you must consult a doctor before lying down. Moreover, for those who are suitable for mixed sleeping, they should be gradual according to their physical condition to ensure safety and avoid possible injuries.

Wrong sleeping position is harmful to health;

1. Sleeping on your stomach will oppress your heart.

People who sleep on their stomachs drool easily. At the same time, if the chest is flat on the bed, it may be a depression in the chest. The biggest drawback of sleeping on your stomach is that it oppresses your heart.

If the time is too long, it may be due to obesity and other reasons, and the chest compression is too heavy, which affects the blood circulation of the whole body, leading to heart discomfort and difficulty breathing. Chinese medicine believes that heart failure is due to deficiency of qi and blood. Therefore, it is necessary to ensure a good breathing state when sleeping.

2, curled up to sleep, will hurt the back of the neck.

A survey shows that in the past six months, one in five people has suffered from back pain and neck pain. The main cause of back pain or neck pain is poor sleeping posture. The most comfortable time for a person's back is when it is straight. Chinese medicine says that deficiency syndrome will appear if blood vessels are not smooth. Therefore, whether you are sitting, standing or lying down, you should do the most comfortable posture, and don't always bend over.

Lying on your back will hurt your lungs.

When sleeping in this position, the enlightened parts of the face are more upward, while qi and body fluid are downward. For example, when sleeping, because the face is facing upwards, saliva flows into the trachea or falls at the root of the tongue, which may easily lead to snoring or coughing, and even cause qi stagnation, which will affect the blood circulation of the lungs, thus affecting the function of the lungs. So it's best to turn over and change your sleeping position when you sleep.

Sleeping on the pillow will block your blood.

Put your arms under the pillow and sleep. You won't move for hours. When you wake up, you will feel that your arm is not your own, and you will feel paralyzed from your shoulders to your fingers.

This is because the radial nerve of human upper arm is injured by compression, which leads to paralysis of forearm, wrist and fingers. During sleep, our qi and blood and breathing gradually enter a stable and regular state. In deep sleep, if we put our arms on the pillow to sleep, and our limbs can't be adjusted because of qi and blood blockage, we will soon enter paralysis.

5, lying on your side, you will get a cerebral infarction.

Experts surveyed 2000 patients with cerebral infarction and found that more than 95% of them have such a sleeping habit, sleeping completely on their side with half of their bodies pressed. This sleeping position will aggravate the blood flow disorder, resulting in slow blood flow in the neck, which is very easy to gradually gather in the injury of the intima of the artery and form a thrombus.
