中风已成为我国居民最主要的致死和致残原因之一,其死亡率和发病率均高于西方发达国家。为深入揭开这一现象的内在原因,我国研究者研究发现,极端气温(热浪或寒潮)较多可能是我国居民中风死亡率发病率居高不下的原因之一:与正常气温相比,热浪或寒潮可使居民中风死亡风险分别增加14%和45%。更为重要的是,热浪或寒潮影响中风的方式截然不同:热浪效应持续时间短暂,3至4天后其健康危害消失;寒潮效应持续时间则较长,可达15至
Stroke has become one of the leading causes of death and disability in China. The mortality rate and morbidity rate are both higher than those in western developed countries. In order to reveal the underlying causes of this phenomenon, researchers in our country have found that more extreme temperatures (heat waves or cold waves) may be one of the reasons for the high incidence of stroke deaths among residents in our country. Compared with normal temperatures, heat waves Or cold spell can increase the risk of death of stroke residents by 14% and 45% respectively. More importantly, the effects of heat waves or cold waves on stroke are quite different: the duration of the heat wave effect is short and the health hazard disappears after 3 to 4 days; the duration of the cold wave effect is longer, up to 15 to
