While you might be tempted to reach for a cold drink to help cool you down in such hot weather, surprisingly hot drinks such as teas and coffees may actually be more effective.
在如许的年夜热天，你或许很想喝杯冷饮来凉爽一下，但使人惊奇的是，茶和咖啡等热饮可能对解暑更有用。
A study in 2012 by researchers from the University of Ottawa looked at the effect of drinking hot drinks on body temperature.
渥太华年夜学的科学家在2012年研究了喝热饮对下降体温的结果。
The results revealed that a hot drink can cool you down, but only in dry conditions.
研究成果揭露，热饮可让你感受凉爽，但只有在干燥的情况中才如斯。
Speaking to the?Smithsonian Mag, Dr Ollie Jay, one of the authors of the study, explained: “If you drink a hot drink, it does result in a lower amount of heat stored inside your body, provided the additional sweat that’s produced when you drink the hot drink can evaporate.”
在接管《史密森学会杂志》采访时，该研究的作者之一奥利·杰博士诠释说：“若是喝热饮，体内贮存的热量就会下降，条件是喝热茶时排出的汗水可以蒸发失落。”
Essentially, when you ingest a hot drink, you start sweating more. If the sweat is able to evaporate, it actually cools you down, more than compensating for the added heat to the body from the fluid.
根基道理是，当你喝热饮时，你会流更多汗，若是汗水可以或许蒸发失落，你就会感应风凉，这个进程中下降的体温跨越了热饮给你增添的体温。
While sweating can be embarrassing, it’s an essential body function to help keep us cool.
虽然流汗使人为难，但倒是人体的一项主要功能，有助于连结风凉。
As the sweat evaporates from the surface of your skin, it removes excess heat by converting the water from a liquid to a vapour.
当汗水从皮肤概况蒸发时，会在水转化为蒸汽的进程中带走过剩的热量。
However, in humid conditions this cooling effect is less effective, so drinking hot drinks won’t help to cool you down.
可是，在湿润的情况中，这类降温结果就没那末较着，是以在湿润气候喝热饮也就不克不及帮忙你解暑。
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.
杰博士诠释说：“在闷高潮湿的气候，若是你穿戴良多衣服，或你汗出如浆，并且没有从皮肤概况蒸发失落，那末喝热饮就晦气于解暑。”
"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.”
“热饮依然会给身体增添一点热量，所以若是汗水没法蒸发，那就选择冷饮。”
Overall, the lesson learned is that in hot, dry conditions, drinking hot drinks will cool you down, but if you’re in a humid location, it’s best to stick to cold beverages.
整体而言，我们获得的结论是，在酷热干燥的气候里，喝热饮会让你感受风凉，但若是气候湿润，最好仍是喝冷饮。
