Insomnia refers to difficulty in falling asleep, such as over 30 minutes, intermittent sleep, such as waking up 2-3 times a night, or waking up early, and the whole sleep time is less than six hours a night, and this phenomenon exists more than three times a week, lasting for 2 to 4 weeks. Long term insomnia can affect our physical and mental state, so if there is insomnia, we should pay attention to find out the reasons. First, whether it is due to jet lag, second, whether it is due to the pressure of work or life, and third, whether there is some anxiety that leads to emotional stress insomnia. If the insomnia can not be corrected after the above reasons are removed, it is suggested that medical treatment and intervention should be carried out in a specialist department.
