Is premature ejaculation related to poor rest?
Generally speaking, whether premature ejaculation (rapid ejaculation) is related to poor rest depends on a comprehensive assessment of factors such as the severity and duration of inadequate rest, as well as individual physical conditions. The specific analysis is as follows:

If the lack of sleep or staying up late is only short-term and no other physical discomfort occurs, the resulting rapid ejaculation is mostly temporary. Short-term sleep deprivation puts the body in a state of fatigue and causes temporary dysfunction in nervous system regulation, thereby affecting sexual performance. As long as sufficient sleep is restored and daily routines are adjusted promptly, this transient symptom of rapid ejaculation usually gradually improves.
However, if there is long-term disruption of sleep patterns and severe chronic sleep deprivation, accompanied by symptoms such as lower back and knee weakness, low energy, and endocrine disorders, then rapid ejaculation may not be solely due to poor rest. Prolonged熬夜 (staying up late) depletes bodily functions, disrupts hormone secretion, impairs reproductive system health, and may even trigger organic conditions such as prostatitis or abnormal nerve sensitivity. In such cases, simply catching up on sleep is unlikely to fully resolve the symptoms.
In daily life, it's important to develop regular sleep habits, avoid staying up late whenever possible, and ensure adequate sleep each night. Reduce screen time from phones and computers before bedtime, and create a quiet, comfortable sleeping environment. Combine this with moderate exercise, such as jogging or squats, to strengthen overall physical health and improve bodily function.
