Winter-swimming has become popular in Beijing. Three years ago, few people went swimming in the icy (冰冷的) water. But now there is a Winter-swimming Enthusiasts’ Club (冬泳爱好者协会) and it has more than 2,000 members. The oldest member is 84 years old and the youngest member is only 7. The members do different jobs at different places. They may be workers, farmers, teachers, students and so on.

Though it is very cold in winter and the temperature of water in the lakes is around 0℃, many winter-swimmers still swim in the icy water. They enjoy themselves in the lakes when other people are wearing heavy clothes.

Why are so many people interested in winter-swimming? Because winter-swimming can be good for their health. Mr. Chen is a good example. He is 69 years old, and he once had heart disease (心脏病) for 26 years. After ten years of winter-swimming, he is now in good health. Scientists are now studying the effects (影响) of winter-swimming on health.
