Whether chronic all-night insomnia leads to sudden death cannot be generalized, but depends on the specific situation. Long-term all-night insomnia is not a complete lack of sleep, but a relatively short and scattered sleep, and may also have a certain amount of compensatory sleep during the day, which usually does not cause sudden death. Only if you do not go to sleep for 24 hours in a row for more than 3 days, you will seriously endanger your body functions. In addition, some patients with cardiovascular and cerebrovascular diseases are at risk of sudden death due to mood swings and rapid increases in blood pressure, which can cause serious life-threatening diseases such as strokes in a long-term all-night insomnia state. Therefore, people with long-term insomnia need to consult a hospital neurology department to remove the causes that trigger insomnia, which can effectively avoid deterioration and prevent the adverse consequences caused by insomnia.
