What causes talking in one's sleep?

The causes of sleep-talking are complex and varied, mainly including the following aspects: 1. **Psychological factors**: Excessive mental stress, stressful events, emotional tension, or anxiety may lead to increased neural excitability, which can manifest as sleep-talking during sleep. 2. **Environmental factors**: An unfavorable sleep environment, such as exposure to noise or bright light, may also increase neural excitability and trigger sleep-talking. 3. **Lifestyle habits**: Consuming stimulating beverages such as strong tea or coffee before bedtime, or engaging in vigorous exercise, may overexcite the brain and increase the likelihood of sleep-talking. 4. **Medical conditions**: Certain diseases, such as neurasthenia, autonomic nervous system dysfunction, and depression, may also cause sleep-talking. These conditions can affect sleep quality, making individuals more prone to talk in their sleep. Sleep-talking has multiple causes and involves various factors including psychological status, environment, lifestyle habits, and medical conditions. To reduce episodes of sleep-talking, it is recommended to maintain healthy lifestyle habits and a positive mental state. If necessary, seek assistance from a healthcare professional. If discomfort occurs, timely medical consultation is advised for proper diagnosis and treatment.
