医疗气象研究表明,人与环境之间的热交换,在气温较高时,体热主要是通过汗液蒸发和肺部呼出的水分而散失。而当气温和湿度达到某一界限时,人体的热量就很难散发出去,若超过了人的耐受极限,就会引发中暑、心力衰竭(简称“心衰”)甚至猝死。有资料表明,当气温达到35℃以上时,死亡人数就 Medical meteorological studies show that the heat exchange between people and the environment at high temperatures, the body heat mainly through the evaporation of sweat and exhaled lungs and the loss of water. And when the temperature and humidity reach a certain limit, the human body’s heat is difficult to send out, if exceeded the limits of human tolerance, it will trigger heat stroke, heart failure (referred to as “heart failure”) and even sudden death. Data show that when the temperature reaches above 35 ℃, the death toll on
