人体有很强的维持体温稳态的能力,能经受住外环境温度的强烈变化。18世纪英国的一个实验生理学家勃莱登于1775年进行的自体试验表明:如果空气干燥,人可以在120℃室温下停留15分钟,并无不良反应,体温仍可保持稳定,而在此温度下,只用13分钟,就可使牛肉烤熟;但若在潮湿的空气中,室温虽只有48℃～50℃,人却只能耐受很短的时间,这是因为汗液不能蒸发的缘故。
Human body has a strong ability to maintain body temperature steady, can withstand the strong changes in the temperature of the external environment. A self-contained test carried out in 1775 by Breton, an 18th-century British experimental physiologist, showed that if the air was dry, one could stay at 120 ° C for 15 minutes without adverse reactions and the body temperature remained stable at this temperature , Only 13 minutes, you can make beef roasted; but if the damp air, although the room temperature only 48 ℃ ~ 50 ℃, people can only tolerate a very short period of time, it is because sweat can not evaporate .
