Old people with hypertension and cardiovascular and cerebrovascular diseases can choose to settle in the south. It is suggested that Sanya in Hainan and Xishuangbanna in Yunnan will not be very cold in winter, which is good for the elderly with hypertension and cardiovascular and cerebrovascular diseases. In fact, I really hope that our country will set up 1-2 State-owned Yang Kang Group Company in these two places, which can combine nursing homes and sanatoriums from all over the country and set up North-South Base Group, which will go to the North Base in summer and the South Base in winter, and migrate from the north to the south to provide for the aged, eat, live, travel and travel. .......

The influence of temperature on hypertension and cardiovascular and cerebrovascular diseases is not a little: temperature has an absolute influence on blood pressure. When the cold temperature drops, blood vessels contract, leading to an increase in blood pressure. When the weather is hot, blood vessels dilate and blood pressure drops. When the weather suddenly gets cold, or the temperature difference between morning and evening is large, the blood pressure fluctuation will be more obvious. Generally speaking, in winter, the range of blood pressure increase is 5 ~10mmhg, even reaching 20mmhg. When the temperature is lower or higher than a certain critical temperature, with the decrease or increase of temperature, the incidence and mortality of cardiovascular and cerebrovascular diseases gradually increase. The obvious change is in winter, because the cold weather is easy to cause cardiovascular and cerebrovascular diseases. When the temperature is low, cold will stimulate blood vessel contraction, increase blood flow resistance, increase blood viscosity, slow down blood flow, easily form small thrombus, cause blood vessel blockage or induce angina pectoris, myocardial infarction, cerebral infarction and other diseases. At the same time, the secretion of catecholamine in human body increases under the stimulation of cold, which causes vasospasm, plaque rupture and platelet aggregation to form thrombus, and induces myocardial infarction and cerebral infarction. In addition, with the sudden drop of temperature leading to the contraction of human blood vessels and the sudden increase of blood pressure, the originally hardened and fragile arterioles could not bear the strong internal pressure, leading to the rupture of blood vessels and cerebral hemorrhage. Winter is the season of cardiovascular and cerebrovascular diseases, and the probability of recurrence of cardiovascular and cerebrovascular diseases such as myocardial infarction, heart failure, sudden cardiac death and cerebral infarction in winter is 2~3 times higher than that in other seasons. Therefore, elderly people with poor cardiovascular and cerebrovascular diseases can settle in warm places in the south, and it is not recommended to settle in humid places in the south. The cold in winter in the south can't adapt to the health of the elderly in the north.
