Sleeplessness is usually manifested in two aspects. Firstly, some patients do not sleep well at night because they do not feel like sleeping, which is a kind of sleep disorder, often related to patients’ emotional tension, anxiety or some bad lifestyles, such as sleeping too much during the day or taking overly excited drugs, which may lead to sleeplessness at night. Another kind of insomnia is called subjective insomnia, in which some patients feel that they have not slept the whole night, but their mental condition is fine during the day, and by asking their companions or family members, they all say that the patients will have even snoring at night, which means they are in the sleep state. In this case, if sleep polysomnography is performed, it can be found that the patient has more complete sleep waves suggesting that he is in the sleep state, which can be called subjective insomnia. If it is for the former case, such as the inability to sleep, it is recommended to adjust the lifestyle by not sleeping too much during the day, and then try to eat less stimulating food, if it is the latter case of subjective insomnia, it is necessary to inform the patient about sleep hygiene education, and if necessary, to go to the hospital for sleep polysomnography, and then explain to the patient that they are actually in a sleep state at night, and that the criteria for determining good or bad sleep If the patient is in good spirits during the day, it can be judged that the night sleep is also good.
