First of all, we should know that the human body spends almost 1/3 of its time sleeping every day. If you don't get enough sleep, you will be very listless the next day, all because sleep can cultivate your mental state well. If you don't have a good rest and lack of sleep, you will be nervous, and there will be factors such as depression, terror, anxiety and irritability.

These factors often cause insomnia or sleep disorder, so you must put an end to sleep disorder insomnia, otherwise, your body will lose more than you gain. Sleep is a very important key for people. Sleep can improve our brain development, because brain development usually develops at night when the brain is relaxed.

While the brain is developing, it will also consolidate our memory and help us recover our energy and physical strength. Physical development also has a lot to do with sleep. Our immune system and nervous system both develop when we sleep at night. Just after entering sleep, our nervous system will protect itself, because at this time, we can't accept any external interference, and it is at this time that our nervous system is thriving and perfecting.

If the nervous system is injured, he will also repair himself. Almost all the repair functions of our body work after sleeping at night, just like the immune system. When you are sick, for example, a cold virus is eroding your body, you will feel very tired during the day and sleepy at night, precisely because your immune system is removing bacteria and viruses from your body bit by bit.
