医疗气象学研究表明,在一年四季之中,气温、气压、气流、气湿等气象要素变化无常的季节是春季。而在春季中,3、4月份天气变化最为突出。在此时段,对于心脑血管病人,尤其是患此病的老年人,由于脏器老化,机能衰退,对外界环境变化适应性差,抵抗力弱,容易引起高血压病情恶化,冠心病诱发心绞痛以及心肌梗死、脑中风等疾病的发生。所以说,在春季尤其是3、4月份做好中老年保健非常重要。心脑血管疾病具有高患病率、高致残率、高死 Medical meteorology research shows that during the year, the temperature, air pressure, air flow, humidity and other weather changes in the volatile element of the season is spring. In the spring, the weather changes are most prominent in March and April. During this period, for cardiovascular and cerebrovascular patients, especially elderly patients suffering from the disease, due to organ aging, decline in performance, poor adaptability to environmental changes, weak resistance, likely to cause deterioration of hypertension, coronary heart disease induced angina and Myocardial infarction, stroke and other diseases. Therefore, it is very important to do middle-aged and elderly health care in the spring, especially in March and April. Cardiovascular disease has a high prevalence, high morbidity, high death
