Don't commit the six taboos when sleeping

1. The pillow is too high

From a physiological point of view, the best pillow size is 8 to 12 cm. If the pillow is too low, it may cause a stiff neck or excessive blood flowing into the brain, causing a swollen head and swollen eyelids the next day. If the pillow is too high, it may affect the smooth flow of the respiratory tract and cause snoring. Moreover, a high pillow for a long time may cause neck discomfort or hunchback.

2. Sleep with your hands as pillow

Putting your hands under your head when sleeping will not only affect blood circulation and cause numbness and pain in the upper limbs, but it will also easily increase the intra-abdominal pressure, which may cause "reflux esophagitis" over time. Therefore, it is not advisable to use your hands as a pillow when sleeping.

3. Cover your head with a quilt

Being masked can easily cause breathing difficulties; at the same time, inhaling the carbon dioxide exhaled by yourself is extremely harmful to your health. This is especially unsuitable for infants and young children, otherwise there is a risk of suffocation.

4. Mouth breathing

Sleeping with your mouth closed at night is the best way to maintain your vitality. Breathing with your mouth open will not only inhale dust, but also easily irritate the trachea, lungs and ribs with cold air. It is best to breathe through your nose. The nose hair can block some dust, and the nasal cavity can warm the inhaled cold air, which is good for your health.

5. Sleep facing the wind

The ability to adapt to environmental changes during sleep is reduced, making it easy to catch cold and get sick. The ancients believed that wind is the root of all diseases and that it can change frequently. Those who are good at regulating themselves should avoid wind and sleep in the dew even in the hottest summer. Therefore, the sleeping place should be away from drafts, and the bed should be a certain distance away from windows and doors.

6. Sleeping while sitting

Some people sit on the sofa after a meal, turn on the TV and make a pot of tea, which is very comfortable. Maybe you are too tired from work and fall asleep while watching TV, which leads to the second major hidden danger! Because sleeping while sitting will slow down the heart rate, dilate blood vessels, and reduce the blood flow to various organs. In addition, the stomach requires blood supply for digestion, which aggravates brain hypoxia and causes dizziness and tinnitus. Some people say that you can just take a break at noon. Who would bring a quilt to the company? Just find a place to stay. It saves you trouble, but your body will protest.
