The causes of the patient's recent total insomnia are complex, and the analysis should be combined with the patient's predisposing factors: 1. Changes in the working environment or living environment can lead to insomnia and sleeplessness. 2. Pay attention to whether it is caused by psychological factors, such as whether the patient is in a state of anxiety and depression due to high mental pressure, and is easily nervous, which leads to anxiety insomnia, difficulty in falling asleep, insomnia and dreaminess. 3. If the patient is engaged in work such as night shift for a long time or stays up late, it is easy to lead to biological clock disorder, and also easy to make the patient always lose sleep. 4. Patients should pay attention to whether it is caused by menopause.
