The common reasons why patients wake up in their sleep are as follows: 1. Physiological reaction: Patients may have sudden external stimuli, such as noise and bright light, during their sleep, resulting in sudden awakening. Therefore, patients should keep the bedroom in a state of light and sound avoidance as much as possible to reduce undesirable external disturbances; 2. Poor sleep quality: for example, excessive mental tension and anxiety, or excessive thinking before bedtime, can also cause patients to wake up in their sleep; 3. Dietary influence: if patients ingest foods that excite the nerves before bedtime, such as coffee, strong tea, or indigestible meat or chili peppers, it can lead to gastrointestinal indigestion, resulting in awakening in bed.
