30% of the time in life is spent in the process of sleeping, and only by ensuring adequate sleep can it be conducive to the repair of various organs and tissues. Although sleep is simple, poor sleep habits can also induce a variety of diseases.

What sleep habits affect health? Pay more attention to these 4 kinds

1. Close doors and windows when sleeping

Most people, when sleeping, will sleep with the doors and windows closed, which is a bad sleep habit. Because when we sleep, we inhale oxygen in the room and exhale a lot of exhaust gas. If the doors and windows are always closed, fresh air will not enter the room, the oxygen content will be reduced, the air will become dirty, and there will be a large number of bacteria and viruses, which is not good for your health. The smaller the room, the greater the harm, so when you go to bed at night, you can open the doors and windows slightly to keep the air circulating in the room.

2. Sleep with the lights on

Our human body will have a certain biological clock, only when it is dark, the body can secrete melatonin, if this routine is broken, it will disrupt the biological clock, in the process of sleep, it is easy for people to feel the pressure of light, affecting the basal metabolic rate, which will make people's blood pressure, pulse and heartbeat abnormal, which will lead to disease. In addition, if you sleep with the lights on all the time, it will reduce the immune function and stimulate the visual system.

3. Sleep with your head covered

In summer, it is very pleasant to turn on the air conditioner and sleep with a thin quilt, but some people like to sleep with their heads covered and think they have a sense of security, but the air in the quilt is relatively turbid and has low oxygen content. For a long time, it will also lead to breath-holding, chest pain, people will be awakened in the middle of the night, and wake up on the 2th day with headache and dizziness, which reduces the quality of sleep. In addition, if the quilt is not washed for a long time, a large number of parasites and bacteria will enter the body through the mouth and nose, and people will suffer from respiratory diseases.

4. Sleep with your arms on your pillow

Sleeping with your arms on your pillow will lead to insufficient blood supply to your arms, causing temporary loss of sensation and local numbness in your arms, and even muscle contractions. It can also cause chest pain and reflux esophagitis. Because when the arms are raised, the muscles are pulled and the diaphragm is displaced, which increases the pressure in the abdominal cavity and compresses the stomach, and the food will enter the esophagus with the digestive juices, so that the esophageal mucosa is in a state of congestion and edema, and eventually erosion occurs. When the diaphragm rises, it puts pressure on the lungs, making it difficult for people to breathe, resulting in general fatigue and chest pain.

Tips

The best sleeping position to stop poor sleep is to lie on your side, which reduces the pressure on your heart and ensures that you get enough sleep.
