Sleep is always insufficient, sleep too long, always feel fatigue and weakness, because the poor quality of sleep or deep sleep time is reduced, mainly light sleep, resulting in the brain and body can not get enough rest, resulting in symptoms of poor sleep. There are the following reasons for this situation: 1. Patients should be clarified whether their sleep environment has any problems, if the environment is poor, there is noise, bright light stimulation, stuffy heat, lack of air circulation, etc., it will seriously affect the quality of sleep. 2. Patients should be clarified whether they have high stress, mental tension, anxiety, which often leads to excessive dreaming. Depression often leads to early awakening and poor sleep quality. Perfecting anxiety self-assessment scale and depression self-assessment scale can help clarify the diagnosis, and if the score is above 40 you need to use anti-anxiety and anti-depressant medication. 3. It is necessary to clarify whether the patient has any physical organic diseases, such as sleep apnea syndrome, which is also the most frequent cause of poor sleep quality. Patients after falling asleep because of poor airway leading to body ischemia and hypoxia, the brain is especially sensitive to hypoxia, which will lead to poor sleep quality, although enough time but always easy to wake up, and always drowsy during the day.
