The extent to which staying up late can cause sudden death cannot be specified, and is related to the individual’s physical condition and the presence of underlying diseases. Staying up late can be harmful because it leads to increased sympathetic excitability, which in turn leads to heart damage and increased blood pressure, so it eventually increases the risk of sudden death, but it is difficult to specify the extent to which staying up late can lead to sudden death, which may be related to individual physique and the basic state of the body. If poor health, and recently often stay up late, there may be some sudden death aura, such as chest tightness, palpitations, dizziness, etc., if at this time still do not pay attention to adequate rest, will increase the chance of sudden death. For people who have been physically fit in the past, the chance of sudden death from occasional late nights is relatively small. It is recommended to pay attention to the combination of work and rest, try to avoid staying up late, and ensure at least 8 hours of sleep every night.
