运动不要多喝水?

If you follow medical news, you have probably heard the campaigns in the UK and the US warning about eating too much salt. It is true that there is often a lot of salt added to prepared food, and sodium can raise your blood pressure, which can lead to a heart attack.

如果你关注医学方面的资讯，你很可能听说过英美两国旨在警告人们不要摄入太多盐分的宣传活动。的确，预制食品中往往含有大量盐分，钠可能会升高你的血压，高血压可能导致心脏病发作。

But cyclists and runners face an entirely different problem — too little salt, says Dr Metzl, who has run 30 marathons and is the author of a medical guide for athletes calledRunning Strong. When it is hot and humid, most people tend to sweat a lot during exercise. Very fit athletes actually sweat more than other people, which sounds counterintuitive, but it helps cool them down.

但梅茨尔表示，自行车运动员和跑步运动员面临着截然不同的问题——盐分摄入太少。梅茨尔参加过30次马拉松比赛，著有为运动员撰写的医学参考书《跑步者健康指南》(Running Strong)。天气炎热潮湿的时候，大多数人会在锻炼中大量出汗。身体非常健康的运动员实际上会比其他人出汗更多，这听起来似乎有悖直觉，但这其实能够帮助运动员降低体温。

There is also a subgroup of athletes whom Dr Metzl calls “salty sweaters”, who not only sweat more than most during exercise but also sweat much more salt. I know because I am one and my sweat is so salty it sometimes irritates my skin.
