After busy and stressful work the whole day, we finally go to bed for a rest. If you can be asleep quickly, congratulations! However, many people are another cases! Why? What cause insomnia?
From a clinical point of view, the number of insomnia cases caused by factors of physiology, disease, drug and diet, is far less than the number of that by psychological factors. To sum up, there are six categories of psychological reasons which lead to insomnia.
1. fear of insomnia
Many insomnia patients worry not to be asleep at night, or try to make their best to fall asleep, but they can not reach their dreams successfully. Higher nerve activity of the human cerebral cortex has two processes: excitability and inhibition. During the day brain cells are in the excited state. After a long day work, the cells need to rest, and to be suppressed to sleep. They will naturally turn sober after a good rest..
The excitation and inhibition of the cerebral cortex coordinate to alternately form a rhythm of sleep cycle. When you are afraid of being wakeful during bedtime, your brain are forced to be excited, which will really let you be sleepless. So, do not think much about whether you can be asleep or not.
2. self-accusation
Some people feel guilty and remorse themselves due to a fault made at daytime, whey they go to bed, they will reappear the scene in their mind and imagine another handling methods. There is no time left during the day, so everything go to mind at night, which excite the brain cells. As a consequence, sleeplessness is unavoidable.
3, expectation
This situation refers to early awakening caused by the expectation or worries of something. For instance, some people are too excited to fall asleep before the announcement of further education admission, job invitation, promotion, job classification results, etc.
4. helplessness
Stimulated by emergencies, some people can not react correctly, and do not know what to do, so that they can not fall sleep at night quickly after much thought.
5. Fear of dream.
Many insomniac people do not have a correct view of the dream, and argue that dream is the performance of poor sleep, and harmful to health, even some people mistakely believe that more than a dream is just a symptom of insomnia. These misconceptions often make people anxious, which affect the quality of sleep.
In fact, science has proven that everyone will make dream at night, dreaming is not just a normal psychological phenomenon, but also a way of working manner of the brain. A repeat of the experience of the day in a dream helps memory and clear out useless information. The dream itself is not harmful to the human body, the psychological state of “bad dream” is harmful which causes psychological burden.
