Although children are good at swimming and fitness, they must pay attention to the water temperature in the swimming pool, otherwise it may affect their health. Experts pointed out that when children go swimming, they should not only have fun, but also pay attention to the change of water temperature, and go ashore as soon as possible when they feel cold.
Each child's adaptability to water temperature is different, and whether the water temperature is suitable depends on the child's feelings. When entering the water, if the child feels that the water temperature is cold, then swimming again is easy to catch a cold. Many boys like to go swimming after playing ball and feel very happy. In fact, it is easy to be infected by germs. Children should be healthy when swimming and have enough rest before swimming.
Swimming in summer is also very important for the choice of location. Pay attention to the density of people in the swimming pool and the ventilation conditions of the swimming pool. Generally speaking, if there is a high density of local people in the swimming pool, one or two of them carry germs, which will easily lead to cross-infection. Therefore, parents must choose swimming places with good water quality and good ventilation.
