A data survey shows that nearly 300 million people in China have sleep disorders. This data shocked the netizens, people did not expect that there are actually so many people can not sleep, there are sleep disorders. Many people say that their insomnia feels like an extremely small number of existence, I did not expect that there are so many people in the country and they have the same symptoms. But more netizens are looking for the causes of sleep disorders. Indeed, there are so many people who have sleep disorders, about which there should indeed be concern. So what exactly causes the problem of sleep disorder? I think there are mainly the following reasons.

One, psychological and mental stress caused by sleep disorders

The biggest reason why many people have sleep disorders is because of excessive psychological and mental stress. These pressures mainly come from life and work, and even some people from the study. Every day's work is busy until very late to do not finish, life in a variety of annoying things stacked, learning to keep up with the speed and so on, these problems over time will inevitably add endless pressure, so that even if people want to sleep well even if they are tired can not sleep.

Second, depression patients generally have sleep disorders

There are also many people who have sleep disorders, is caused by depression. So far, there are many reasons for depression, but many people with sleep disorders do not know that they suffer from depression at first, because they go to the hospital to check why they can't sleep, only to realize that they have a serious depression.

Three, long-term stay up late to cause disruption of the biological clock and thus sleep disorders

There is also a group of people with sleep disorders because of long-term stay up late to cause disruption of the biological clock, that is to say, this type of people are ? The reason for this is the fact that they are not the ones to blame. The long term can not help but to stay up late, a long time to the biological clock disrupted, so want to sleep well found that can not be done. This group of people is easier to treat for sleep disorders than those with other causes of sleep disorders.
