How many people toss and turn and have trouble falling asleep at night?

How many people are there who never wake up from sleep all day long, not to mention sleeping until noon on weekends?

We don’t need to say much about the importance of sleep. Too little sleep can be very harmful to your body and mind, but did you know that too much sleep is also not good?

How bad is it to sleep too much? Why is that? Let’s find out!

Generally speaking, as long as you rest on time and after a night of recovery, all body functions have returned to normal levels and you will be full of energy.

However, if you often sleep in, the sleep center will be in an excited state for a long time, and other nerve centers will be suppressed for too long, and their function of recovering activity will become relatively slow. This will not only make you feel groggy instead of energetic, but will also affect the memory area, causing you to be slow to react and dull, and your intelligence will decrease.

In addition, the body's muscle tissue has missed the best opportunity to exercise. After getting up, you will find that your arms and legs are soft and your whole body is weak.

So, it is not good to sleep too short or too long. An adult only needs to sleep 7-9 hours a day.
