Long-term night shift work and staying up late lead to a decline in autonomic nervous system function, leaving the brain unable to stop thinking.

Long-term night shifts and staying up late can indeed adversely affect the autonomic nervous system, leading to functional decline. When subjected to continuous psychological stress and unhealthy lifestyle habits, the autonomic nervous system may become dysfunctional, manifesting symptoms such as palpitations, chest tightness, and increased heart rate.

For this condition, patients should first adjust their作息 (作息 should be translated as "作息" here to maintain the original meaning in Chinese, which refers to one's routine or schedule) schedule and ensure adequate sleep, avoiding staying up late as much as possible. Learning to properly balance work and rest periods, and engaging in relaxation techniques such as yoga and meditation can help alleviate psychological stress. In terms of diet, maintaining nutritional balance and consuming more foods rich in protein and vitamins can aid in nervous system recovery. Engaging in appropriate physical exercise can improve physical fitness, enhance cardiac function, and also help improve sleep quality and reduce psychological stress.
