Sleep with your head covered and tell your fortune.

There are all kinds of proverbs circulating among the people, including the wisdom of ancestors, the feelings left to future generations and various warnings. Some proverbs are widely circulated because they were recognized by people at that time, otherwise they would not be circulated.

Sleeping is an indispensable daily activity for people. Some people say that one-third of a person's life is spent in bed. Although it is a bit exaggerated, sleeping does take up a lot of time in a day. So as the saying goes: people sleep for three times, and their lives are thinner than paper. What does that mean? What are the three senses?

1, you can't sleep until your hair is dry.

Some people take a shower after a busy day and fall asleep before their hair is dry. In fact, if you sleep before your hair is dry, it will do great harm to people's health and even bring serious consequences.

First of all, a person is in a relaxed posture when sleeping. If the hair is not dry, it is easy to catch cold, leading to dizziness, headache and other consequences, and may also cause a cold. Moreover, the humid environment is easy to cause bacteria to breed, and the pillow is easy to be moldy and easy to cause diseases.

Not to mention the slight consequences of damaging hair, it may even lead to facial paralysis. Because when people are playing, because their hair is not dry and they are stimulated by coldness, it is easy to cause nerve spasm, muscle twitching and facial paralysis.

So everyone must wait for their hair to dry before going to bed, otherwise it may be harmful to their health.

You can't sleep with your head covered.

Some people like to sleep with their heads covered. They think it is quieter and easier to fall asleep. In fact, this is just a psychological effect. Sleeping with your head covered is actually an unhealthy behavior and of course harmful.

First of all, people need to breathe all the time, and sleeping is no exception. Therefore, if there is no smooth breathing environment, it will cause physical harm. Sleeping with your head covered is an unhealthy breathing environment, because the quilt is a relatively closed area, and fresh air cannot circulate, which may cause harm to your body.

In the quilt, the air can't circulate, and the exhaled carbon dioxide can't come out in the quilt. When inhaling, these wastes are sucked back into the lungs, which eventually leads to higher and higher carbon dioxide concentration, which may cause hypoxia. Breathing such air for a long time is naturally bad for your health.

So why do some people wake up the next day and feel backache and poor spirit? That's probably why. Although there is plenty of time to sleep, even if you sleep for a long time, you will not get a good rest in a bad sleeping environment.

3, can't sleep upside down day and night

As the saying goes, work at sunrise and rest at sunset. Most people work during the day and rest at night. Once sleep is reversed day and night for a long time, it may break the balance of human biological clock, causing physical dysfunction and serious consequences.

Some people have to stay up late, but they still have to take care of themselves. Every living thing has its own specific rules of life, and once this rule is broken, it may bring harm to the body. If the day and night are reversed for a long time, it will lead to decreased immunity, easy to get sick, easy to get angry and grumpy.

Therefore, as the saying goes, a person's life is thinner than paper after three senses. There is still some truth. Sleep is a very important time for a person to replenish energy. Only with good sleep can we have the energy to meet the challenges of a new day. What do you think of this?
