Swimming can lose weight. Swimming, like jogging, is one of the few exercises to lose weight, and swimming for an hour can consume 1 100 calories. When swimming, you need to soak in water, and the heat transfer of water is greater than that of air, so the heat lost by human body in water is faster and more than that in air. However, although swimming can play a certain role in losing weight, we should also pay attention to the time and interval of swimming every day, because long-term swimming can lead to skin diseases.
