冰岛地热泳池：简单而普遍的全民健康习惯
In Iceland, people love to swim all year. But the water is not cold. It is hot from under the ground. This is called geothermal water. Many towns have outdoor pools with this warm water. The pools are open even when it snows.
Every morning, old people and young people go to the pool. They swim slowly or just sit in the hot tubs. The warm water helps their bodies relax. It also makes muscles feel good after hard work. Doctors say light swimming is very healthy for the heart.
