(1)老年人。老年人适应能力较差,抗病能力下降,且循环系统功能减弱,所以最易受到“倒春寒”危害。一些慢性病患者血压波动增大,最易诱发中风、心肌梗死等,高血压病、脑出血发病率明显增高,这是因为交感神经受寒冷刺激兴奋度增高,全身皮肤表层毛细血管收缩,使血流阻力增大,从而导致血压升高。(2)儿童。儿童免疫功能相对较弱,对“倒春寒”难以适应。
(1) the elderly. Older people are less able to adapt, have lower disease resistance, and weakened circulatory system, so they are most vulnerable to “cold in spring”. Some chronic diseases in patients with increased blood pressure fluctuations, the most likely to induce stroke, myocardial infarction, hypertension, cerebral hemorrhage significantly increased morbidity, it is because the sympathetic by cold stimulation increased excitability, systemic skin capillary capillaries, blood flow Resistance increases, leading to elevated blood pressure. (2) children. Children’s immune function is relatively weak, difficult to adapt to “late spring cold”.
