What will happen if I sleep too much? Will it be harmful?

It is well known that lack of sleep is bad. The normal sleep time for people is 8 hours. Some people think that sleeping longer is good for the body, but the result is just the opposite. If people sleep for a long time, it will cause great harm to the body. Sleeping too much will not only make you fat, but the brain also rests when you sleep, and less blood circulation will cause brain hypoxia.

The longer people sleep, the lazier they will become. When the human brain is in the relaxation stage, they will feel listless and more sleepy.

A study by physiologists found that when people sleep, their breathing slows down and the accumulation of carbon dioxide in the blood increases. If they sleep for more than ten hours a day, the carbon dioxide accumulated in the blood will become an anesthetic in the human body, making people drowsy. This is why people want to sleep more and more as they sleep. At the same time, long sleep time will reduce the excitability of the cerebral cortex due to long-term inhibition, leading to slow reaction and decreased memory. In addition, since the basal metabolism decreases during sleep, excess calories will be converted into fat and accumulated in the body, making people fat.

This is why people feel groggy the more they sleep. At the same time, long sleep time will reduce the excitability of the cerebral cortex due to long-term inhibition, leading to slow reaction and decreased memory.

Experts from the China Sleep Association pointed out that sleeping too long, like not getting enough sleep, can lead to mental fatigue, physical tiredness and a decreased metabolic rate. Because after sleeping too long, the human heart beat will slow down, the metabolic rate will also drop very low, and the muscle tissue will relax. Over time, people will become lazy, weak, and even their intelligence will decline. Therefore, the idea of ​​increasing sleep time to gain health is not only incorrect, but also counterproductive and shortens life.
