高血压病是中老年的多发病、常见病,尤其是冬季易使病情发展。这是因为:1.低温可使体表血管弹性降低,外周阻力增加,使血压升高,进而导致脑血管破裂出血;2.寒冷的刺激还可使交感神经兴奋,肾上腺皮质激素分泌多,从而使小动脉痉挛收缩,增加外周阻力,使血压升高;3.寒冷还可使血液中纤维蛋白原的含量增加,血液粘稠度增高,促使血液中栓子的形成。因此,高血压病人在冬季要注意做好自我保健,预防中风发生。首先,注意防寒保暖,避免严寒刺激,特别是
Hypertension is a common disease in middle-aged and elderly people, especially in winter. This is because: 1. Low temperature can reduce the body surface elasticity of blood vessels, peripheral resistance increases, so that blood pressure, which led to rupture of cerebrovascular bleeding; 2. Cold stimulation can also make sympathetic excitement, adrenocorticotropic hormone secretion and thus So that small artery spasm contraction, increased peripheral resistance, blood pressure; 3. Cold can make the blood fibrinogen content increased, blood viscosity increased, prompting the formation of blood emboli. Therefore, hypertensive patients in the winter should pay attention to self-care, prevention of stroke. First of all, pay attention to cold warm, to avoid cold stimulation, especially
