Swimming is a good aerobic exercise. When swimming, people's metabolism is very fast, and they can consume 1 100 kilojoules of heat in 30 minutes. At the same time, the thermal conductivity of water is 24 times higher than that of air, and the water temperature is generally lower than that of air, which is also conducive to heat dissipation and heat consumption. Therefore, swimming consumes much more energy than running and other land sports, especially slimming.

In addition, the buoyancy, resistance and pressure of water is an excellent massage for human body, which can play a role in beauty.
