As insomnia is a growing problem in our lives and in our work, here is a little bit of psychology related to insomnia. Many books mention that worry is the cause of insomnia. In fact, if worry is the direct cause of insomnia, personality may be the determining factor in whether or not you are prone to worry. The same thing, such as “can’t sleep” thing, will be overly negative evaluation of the restless people. In fact, lying in bed and can not sleep but 30 minutes, but he will feel an hour, or even longer. And optimistic people will think “just a little sleepless, it’s no big deal.” Not only can not sleep this thing, easy to restless people think more than ordinary people about everything. If they are not feeling well, they think about the worst aspects (catastrophic cognitive patterns). They will feel distressed in the face of most things. Therefore, instead of saying that worry is the cause of insomnia, “sentimental personality (anxious personality)” is the real culprit. Treatment: 1, psychological cognitive therapy: release the worries, can not solve the problem, learn to give up or slow solution, 2, relaxation therapy: ① EEG biofeedback therapy, ② meditation before bed: let the muscle release helps to improve sleep. 3, drug therapy: medication under the guidance of a specialist.
