　　People go in for various kinds of physical training, and winter swimming is one of them．We can have a cold wind bath, an icy water bath and a sunbath at the same time in the open air of winter．When we have taken off our clothes and are exposed to the cold air, all parts of our body are stirred up by the cold, making us eager to go into the water．

　　We dive into the cold water and swim．We come out just when our hands and feet are beginning to feel numb．The only thing we think about in the cold water is how to withstand to cold．At this moment our brain is relaxed and at rest．This improves our metabolic functions(新陳代謝)．

　　After the‘three baths’of air, water and sun, we feel warm, relaxed and comfortable．

　　Winter swimming is enjoyable and good for health．That is why it is becoming more popular than ever before．
