Swimming can first exercise, enhance vital capacity, and at the same time increase self-help ability. Moreover, if you can, you can save others. Swimming can not only keep fit, but also lose weight. Swimming is the most slimming exercise. In many sports, why is it the easiest to lose weight? Because the temperature of water is often lower than that of air, the energy of human body is transferred to water through heat transfer. In order to maintain its own questions, the human body will constantly consume its own energy, which is easily dissipated in water. At the same time, swimming consumes its own physical strength, which will further consume its own fat, which will generate energy at the same time, and this part of heat will generate heat. In fact, the human body will consume more energy when exercising in a relatively low temperature environment, such as in winter, but even in winter, it will not consume more energy than in water.
