What reason is always tired to want to sleep recently

summary

In life, people often want to sleep. Generally speaking, the emergence of the old want to sleep is also caused by a variety of factors. Next, let's understand the specific reasons for the old want to sleep.

What reason is always tired to want to sleep recently

First: the first reason is: lack of sunshine. People who rarely bask in the sun are also prone to symptoms of persistent fatigue syndrome. Sunshine plays an indispensable role in mediating human emotions. It is not easy to feel depressed or tired in the sunshine. Lack of sunlight can lead to a lack of serotonin, a chemical component in the body that controls happiness, which is also related to the lack of vitamin D intake. Vitamin D helps us absorb sunlight and is a major source of serotonin.

Second: the second reason is that the water supply is insufficient. If people's body is short of water for a long time, it will have a serious impact on their mental work. Because the body is short of water, there will be less body fluid that can supply the brain, and the oxygen and nutrition that brain cells can absorb will be reduced, so they will not be able to work normally and efficiently. Even a slight lack of water makes it impossible to concentrate.

Third: the third reason is: lack of exercise. Although exercise is very important to human health, remember that if you don't exercise regularly, you will feel 10 times as tired as usual. Exercise can help you deliver oxygen and glucose to your whole body. Another advantage is that within an hour after exercise, you will feel energetic. This is because the strong contraction of the heart makes more nutrition and oxygen flow in your whole body, and the energy level of the human body rises.
