Why does weather change lead to stroke?

Many people, who may not understand this very well, think that there is no connection between the two, but in fact, the relationship between them is very close, because turbid weather can disorder the vascular regulation function of the human body, thus improving the conditions for the occurrence of diseases. If the temperature drops suddenly, it will lead to the contraction of blood vessels and the increase of blood pressure, which will easily lead to the bleeding of patients with cerebral vascular rupture and the occurrence of diseases. If the temperature rises suddenly, the sweating frequency increases and the blood is concentrated, it will lead to cerebral thrombosis, thus increasing the incidence of stroke. It is said that some experts have counted that the lower the temperature, the higher the air pressure and the higher the incidence of cerebral hemorrhage. Therefore, if the elderly usually have high blood pressure, heart disease and other risk factors that can induce stroke, we must strengthen the work of keeping warm in winter and heatstroke prevention and cooling in summer, and we can use the weather forecast to do self-care.
