Why can't girls sleep?

Night is the time for our body to rest. After a busy day, sleep can restore the body to full energy. But some women have trouble sleeping. What’s going on? In fact, sleep problems do not only occur in women. Many elderly people and men also suffer from insomnia. There are many reasons for insomnia, most of which are caused by physical factors and habits.

1. Personal factors: I have insomnia or depression, which makes me not sleepy at night, or I feel sleepy but still can't fall asleep;

2. Environmental factors: Sometimes it is because of the change of sleeping environment, including the influence of indoor environment and outdoor noise;

3. Life factors: Adults or middle-aged people often suffer from insomnia because of work or some trivial matters in their family;

4. Psychological factors: For example, teenagers cannot sleep because of the pressure of going to school, or middle-aged people cannot sleep because of the psychological burden caused by the life goals;

5. Other factors: Being too nervous, excited, or eating or drinking too much before going to bed may cause insomnia at night.

Insomnia can be divided into primary and secondary types according to its cause.

1. Primary insomnia

There is usually no clear cause, or insomnia symptoms remain after excluding possible causes of insomnia. It mainly includes three types: psychophysiological insomnia, idiopathic insomnia and subjective insomnia. The diagnosis of primary insomnia lacks specific indicators and is mainly a diagnosis of exclusion. When the possible causes of insomnia have been ruled out or cured, but insomnia symptoms still remain, it can be considered primary insomnia. Clinically, it is found that the causes of psychophysiological insomnia can be traced back to the impact of a certain or long-term event on the functional stability of the patient's brain limbic system. The imbalance in the stability of the limbic system function eventually leads to the disorder of the brain's sleep function and the occurrence of insomnia.

2. Secondary insomnia

It includes insomnia caused by physical illness, mental disorders, drug abuse, etc., as well as insomnia related to sleep apnea, sleep movement disorders, etc. Insomnia often occurs at the same time as other diseases, and it is sometimes difficult to determine the causal relationship between these diseases and insomnia. Therefore, in recent years, the concept of comorbid insomnia has been proposed to describe insomnia that is accompanied by other diseases.
