秋冬季节是脑血管病的高发季节,特别是已经患有高血压、糖尿病、动脉硬化等病的人更增加了突发脑血管病的危险性。据统计,50%以上的中风患者发生在秋冬季节。为什么秋冬季节脑血管病多发呢?首先,秋冬时节气温气流等气象要素变化剧烈,气温偏低,人体受到寒冷刺激后,会导致交感神经兴奋,全身毛细血管收缩,使心、脑负荷加重引起血压升高,脑部缺血缺氧加速了血栓的形成。其次,秋冬时节气候干燥,人体消耗水分多,容易造成体内缺水。缺水后,血液粘稠,血流减慢,还会因血容量不足造成缺血性脑中风。最后,老年人对外界环境变化适应性差,也很容易成为脑中风的诱发因素。因此,老年人在气候多变的秋冬季节一定要提高警惕。
Autumn and winter cerebrovascular disease is the high season, especially those who have suffered from hypertension, diabetes, atherosclerosis and other diseases also increased the risk of sudden cerebrovascular disease. According to statistics, more than 50% of stroke patients occur in autumn and winter. Why autumn and winter cerebrospinal diseases occur? First of all, autumn and winter weather temperature and other meteorological elements change dramatically, the temperature is low, the human body is stimulated by the cold, will lead to sympathetic excitement, systemic capillary contraction, heart, brain stress caused by increased blood pressure Increased, cerebral ischemia and hypoxia accelerated the formation of thrombus. Second, the autumn and winter climate is dry, the body consumes more water, easily lead to body water shortage. After lack of water, the blood viscosity, blood flow slowed, but also due to lack of blood volume caused by ischemic stroke. Finally, the elderly adapt poorly to the external environment and are also likely to be predisposing factors for stroke. Therefore, the elderly in the changing autumn and winter climate must be vigilant.
