beware of the old man stroke summer temperatures of summer continues to heat stroke incidence can be greatly increased. According to expert introduction, heat stroke prevalence of about 50 people both middle-aged, also have 80 years old, but still basically give priority to with old people, especially with hypertension, cerebrovascular chronic diseases, such as the old people.
some of them wrong to think that stroke will only occur in winter, actually 6-8 months of summer is the season, especially stroke incidence high temperature, depression hot weather will greatly increase the incidence of stroke in patients with cerebral infarction, the majority, take about 90 percent. Stroke in old people great harm to, such as not timely diagnosis and treatment will cause paralysis, and even have dangerous life, so when the temperature rise to 32 ℃ above shall actively prevention.
body water vbi incline is inducement
summer body moisture loss to a shortage of water, especially the elderly rapid originally the moisture inside body is little, plus days, the body is hot perspire more easier to water shortages. When the temperature in 32 ℃ above, the thermoregulatory depend mainly on the evaporative cooling purposes to sweat. Then people everyday sweating party dress will be roughly 1,000 milliliter above. Elderly itself the moisture inside body is less, the more easily water shortage. The body once a shortage of water, blood volume is insufficient, blood viscosity heighten, elevated blood pressure, cause losing to the brain blood obstructed. So this through subcutaneous blood circulation cooling method to realize the elderly in bad cardiac function, it is a kind of physical burden, can make the old high blood pressure, heart disease patients with hemorrhagic stroke happened.
