    Sweat it out – in a bath! 泡熱水澡等于做運動

    你想要一個輕松的減肥方法嗎?既不用去健身房鍛煉,也不需要在游泳池里游無數個來回?一項研究在比較了運動鍛煉和泡熱水澡的相對益處后發現,通過泡熱水澡消耗的卡路里和快步走消耗的熱量是一樣,而且,飯后泡澡比運動能更多地降低血糖含量。在本期《隨身英語》里,我們探討為什么泡個熱氣騰騰的澡對你的健康有益。

    課文內容

    詞匯:?Exercise 鍛煉

    You might think that to lose weight you need to do strenuous exercise – pedalling furiously on an exercise bike, for example, or doing lengths in your local pool. Well, you may be pleasantly surprised to learn that lying in a steaming bath can bring the same benefits as exercise, without the need to sweat profusely in the gym!

    These were the findings of an experiment comparing the relative benefits of exercise and hot baths that was carried out by Dr Steve Faulkner of Loughborough University. The volunteers first lay in a hot bath and then ate a light meal, while their blood sugar level was monitored and the number of calories they burnt was measured. The experiment was then repeated, but instead of having a bath, the participants did an hour’s vigorous exercise on a bike. The results from both activities were compared with unexpected results.

    “What we found”, said Dr Faulkner, “was an 80% increase in energy expenditure, just as a result of sitting in the bath for the course of an hour”. You burn 140 calories – not as many perhaps as if you had worked out on an exercise bike, but the same number as if you had been on a brisk walk. The real surprise, however, came in the blood sugar level results. The peak glucose output, the amount of blood sugar in the blood after a meal, was on average10% lower after the bath compared to that after exercise.

    Dr Faulkner’s explanation for this phenomenon is that when you are in a hot bath, proteins, known as ‘heat shock proteins’ are released, which help divert the sugar from the bloodstream to the muscles. It’s important to keep blood sugar levels down to avoid damage to the arteries and nerves.

    Don’t think, though, that you can hang up your trainers just yet! You should aim to do at least 150 minutes of moderate-intensity exercise a week. But, if you are one of those people who need to control their blood sugar levels – if you have type-2 diabetes for example or find it hard to exercise – why wait? Grab a towel and start running the hot tap!
