”Cerebral stroke is also known as “stroke” or “cerebrovascular accident”. It is an acute cerebrovascular disease, which is a group of diseases caused by the sudden rupture of blood vessels in the brain or the blockage of blood vessels, resulting in the failure of blood flow to the brain and causing brain tissue damage. The incidence of ischemic stroke is higher than that of hemorrhagic stroke, accounting for 60% to 70% of all strokes. Occlusion and stenosis of the internal carotid artery and vertebral artery can cause ischemic stroke, which is more common in men than in women over the age of 40 and can cause death in severe cases. The mortality rate of hemorrhagic stroke is high. Surveys show that stroke has become the first cause of death in China in both urban and rural areas combined, and the leading cause of disability in Chinese adults. Stroke is characterized by high incidence, high mortality and high disability rates. Different types of stroke are treated in different ways. Because of the persistent lack of effective treatment, prevention is currently considered the best measure, with hypertension being an important controllable risk factor for stroke, and therefore antihypertensive treatment is particularly important to prevent stroke onset and recurrence. Education on stroke risk factors and aura symptoms should be strengthened for the whole population in order to truly prevent and treat strokes. What are the factors that trigger stroke in hot weather? The hot weather makes blood pressure fluctuate, which can easily lead to cerebrovascular rupture; Second, the high temperature causes emotional tension and increases the stress response in the body, which can lead to cerebrovascular disease; Third, a large amount of water in the body is evaporated by high temperature, and blood viscosity rises, which can easily induce cerebral thrombosis; Fourth, many people have poor sleep, poor rest, and disordered diet in summer. The body is in a state of fatigue and stress, the level of hormone release in the body changes, stimulating vascular contraction and inducing vascular disease. In addition, diabetic patients can stimulate the endothelial tissue of blood vessels due to the increase of blood sugar, leading to atherosclerosis and inducing stroke attack.
