Weight loss: Swimming is a sport that requires the whole body's participation, so with the whole body's exercise, the muscles of all parts will be exercised, and the body's calories and fat will be consumed faster. In addition, when swimming, the body is directly immersed in water, which requires you to make more efforts to resist the resistance of water, so it is very effective for losing weight.

It is best to go to the swimming pool when swimming. When swimming in the wild, the water is cold and it is easy to cramp after going down. Secondly, the water depth and velocity are different, and there are complicated situations such as hidden holes, culverts, aquatic plants and silt, which are prone to accidents.

Matters needing attention

Although swimming has many benefits, you should not exercise excessively. Because water can conduct heat, people will constantly release heat through water when swimming. If the swimming time is not long, the human body will keep the heat in the body through conditioned reflex such as closing pores and contracting blood vessels to maintain the needs of human tissues.

Swimming for too long, the human body loses heat, and the body temperature regulation function is destroyed, leading to contraction of skin blood vessels, dilation of venules, slow blood flow, and even stagnation in subcutaneous veins. In this way, the human body will have uncomfortable symptoms, leading to blue skin, black lips, tiny goose bumps, and even convulsions in severe cases. In this case, it is easy to cause colds, tachycardia and muscle strain.
