1, not burned by ultraviolet rays. In the hot summer, the damage of ultraviolet rays is even more fierce. I believe that many friends who suffer from it in the open-air swimming pool are deeply touched, and their skin is severely sunburned and cannot be recovered for ten days. This shows how expensive it is to swim in an open-air swimming pool. However, the constant temperature swimming pool in the fitness club can completely avoid the damage of ultraviolet rays, so you don't have to worry about the sun exposure in summer.
2. The constant temperature of swimming pool water is 26-28 degrees. Ordinary swimming pools use cold water. Because the water temperature is low (0-10 in winter and 10 -20 in summer), few people can swim in cold water, especially children, and there is a great possibility of catching a cold. Constant temperature swimming pool, heated by heating equipment, keeps 26-28 degrees all year round, which is suitable for human body temperature and allows you to bid farewell to the risk of swimming and catching cold.
3, not affected by the weather. Every rainy day and winter, the open-air swimming pool can only be closed, and swimmers are reluctant to go swimming. Due to the weather, the opening of the swimming pool is very low. What I hate most is coming out of the swimming pool, and a burst of cold water blows, which is easy to catch a cold. On the other hand, the constant temperature swimming pool in the fitness club can directly ignore many problems brought by the open-air swimming pool because of indoor reasons.
