Many people are getting more and more sleepy. What are the reasons for this phenomenon?

The quality of sleep is not good, and many people get more and more sleepy. After a sleep, they feel like a fake sleep. The main reasons for getting more sleepy are as follows: first, sleeping for too long and the concentration of carbon dioxide in the body is too high. Second, mental stress is too great. Third, the quality of sleep is not good.

First, we sleep for too long, which leads to the high concentration of carbon dioxide in our body, which inhibits our brain activity. After we go to sleep, the breathing frequency will drop, and the concentration of carbon dioxide in our body will gradually increase. The increase of carbon dioxide will inhibit our brain activity and make us feel groggy. So when we sleep for more than 8 hours, we will feel very tired and uncomfortable as if we didn't wake up. Second, the mental stress is too great, which leads us to sleep without real relaxation. Nowadays, the life pressure of adults is very high, so our mental pressure is also very high. When we sleep, if we are relaxed and calm, then we will fall asleep quickly and the quality of sleep is relatively high. However, if we are particularly stressed, we will not be able to sleep well. At this time, even if we sleep for a long time, we will still feel sleepy after waking up.

? Third, the quality of our sleep is too poor. How to judge your sleep quality? Sleep can be divided into deep sleep and shallow sleep. When we enter deep sleep, our bodies can be completely relaxed, and we will be full of energy after waking up. But if most of our sleep is light sleep, even if we sleep for a long time, our bodies still can't rest.
