Why do I want to sleep but can’t fall asleep?

When you want to sleep but can't, we say you have insomnia. Insomnia is divided into primary and secondary. Primary insomnia is due to psychological reasons. Too much stress, thinking too much, etc. can cause insomnia. Secondary insomnia is caused by the indiscriminate use of drugs or mental disorders, sleep disorders and other diseases. No matter what the reason is, you must learn to relax and relieve stress, and you will feel much better.

1. Primary insomnia usually lacks a 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.

3. Clinical manifestations The clinical manifestations of insomnia patients mainly include the following aspects: 1. Disorders in the sleep process, including difficulty falling asleep, decreased sleep quality and reduced sleep time. 2. Daytime cognitive dysfunction: Decreased memory function, attention function, and planning function lead to daytime drowsiness and decreased work ability. Daytime sleepiness is prone to occur when stopping work. 3. Dysfunction of the autonomic nervous system and its surrounding areas. The cardiovascular system is manifested by chest tightness, palpitations, unstable blood pressure, and peripheral vasoconstriction and dilation disorders; the digestive system is manifested by constipation or diarrhea, stomach bloating; the motor system is manifested by neck and shoulder muscle tension, headache, and low back pain. The ability to control emotions is reduced, and people become easily angry or unhappy. Men are prone to impotence, and women often experience decreased sexual function. 4. Other systemic symptoms are prone to short-term weight loss, decreased immune function and endocrine dysfunction.
