Stroke, also known as cerebral stroke, is a major chronic disease that currently endangers the health of our population. Seasonal changes can lead to a high incidence of cardiovascular and cerebrovascular diseases, mainly because cold weather can lead to peripheral vasoconstriction, which increases the load on the heart and induces a lack of blood supply to the heart and brain. In cold weather, you should pay attention to the following aspects to prevent stroke attacks: 1, it is not easy to go out too early in the morning, when you go out, you should pay attention to keep warm, not too long outside in the morning exercise. 2. Keep your blood pressure stable, test it daily, and adjust your antihypertensive medication appropriately. About 30% of cerebral infarction patients will have a small stroke warning when they have a major attack, such as transient dizziness, transient limb numbness and weakness, transient distorted mouth and eyes, drooling, transient unfavorable speech, etc. In case of sudden onset of a major stroke such as hemiplegia, aphasia or even coma, you should call the emergency system and go to a hospital with thrombolysis or arterial thrombolysis. The general public should know more about stroke.
