基本原理是,当你喝热饮时,你会流更多汗,如果汗水能够蒸发掉,你就会感到凉爽,这个过程中降低的体温超过了热饮给你增加的体温。
While sweating can be embarrassing, it’s an essential body function to help keep us cool.
尽管流汗令人尴尬,但却是人体的一项重要功能,有助于保持凉爽。
As the sweat evaporates from the surface of your skin, it removes excess heat by converting the water from a liquid to a vapour.
当汗水从皮肤表面蒸发时,会在水转化为蒸汽的过程中带走多余的热量。
However, in humid conditions this cooling effect is less effective, so drinking hot drinks won’t help to cool you down.
但是,在潮湿的环境中,这种降温效果就没那么明显,因此在潮湿天气喝热饮也就不能帮助你解暑。
Dr Jay explained: “On a very hot and humid day, if you’re wearing a lot of clothing, or if you’re having so much sweat that it starts to drip on the ground and doesn’t evaporate from the skin’s surface, then drinking a hot drink is a bad thing.
杰博士解释说:“在闷热潮湿的天气,如果你穿着很多衣服,或者你汗如雨下,而且没有从皮肤表面蒸发掉,那么喝热饮就不利于解暑。”
"The hot drink still does add a little heat to the body, so if the sweat’s not going to assist in evaporation, go for a cold drink.”
