Benefit 3: Make children’s heart stronger Due to the buoyancy of the water, as well as the water waves and water pressure on the skin of young children are playing a massage effect on the peripheral blood vessels, will make children’s heart get a good exercise. Swimming increases the oxygen consumption of the whole body muscles of young children, and the pressure of water on peripheral veins effectively promotes blood circulation and improves the heart function of young children. It has been measured that the heartbeat of infants and toddlers who can swim is generally 6 times-8 times lower than that of those who cannot swim. Benefit 4: Improve children’s lung capacity When swimming, the pressure of water on the thorax makes lung capacity increase, which has a good effect on the development of young children’s thorax.

Benefit seven: improve the resistance to immersion in water heat dissipation fast, energy consumption. In order to replenish the heat emitted by the body as soon as possible, for the needs of the hot and cold balance, the nervous system will respond quickly, so that the body’s metabolism accelerates, enhancing the body’s ability to adapt to the outside world, to resist the cold. People who often participate in swimming, due to the improvement of thermoregulation function, it is not easy to catch a cold, but also improve the endocrine function of the human body, is the pituitary gland function increased, thus improving the resistance to disease and immunity.
