The most common cause of cerebral hemorrhage is hypertension, which can lead to vascular sclerosis of small blood vessels in the skull and vitreous changes of arteries, and emotional excitement and exertion can lead to rupture of blood vessels, thus causing cerebral hemorrhage. Frequent late nights can lead to excessive mental stress, hardening of blood vessels, plaque formation, resulting in the formation of hypertension. In addition, the immunity of the body decreases when staying up late, and mood swings may trigger hypertensive cerebral hemorrhage, so you should avoid staying up late, ensure sufficient sleep and proper exercise to ensure that blood pressure is controlled within the normal range.
