Even if you soak in the swimming pool, because the water temperature in the swimming pool is generally lower than the human body temperature, in order to maintain the body temperature, the human body will automatically consume heat. Therefore, water exercise is more effective than air exercise, with twice the result with half the effort, and it can also exercise the muscles around the internal organs.
2. Enhance cardiopulmonary function. This is because the friction of water flow on human body will greatly improve the blood return speed of the heart. This whole-body exercise increases the blood transfusion of the heart and brain, which is also beneficial to the prevention and treatment of cardiovascular diseases.
3. Enhance cold resistance. Human capillaries contract when they meet cold water, and expand due to lack of oxygen during exercise, which enhances the ability of nervous system to control capillary contraction and expansion, and enhances the cold resistance of human body to some extent.
Swimming can also improve people's coordination ability. Because swimming is a synchronous movement of limbs, long-term swimming will make limbs more flexible.
5, swimming also has a certain skin care effect. During swimming, washing the skin with water can promote blood circulation and make the skin more moist.
Precautions:
1, never swim on an empty stomach. In the process of swimming on an empty stomach, accidents may occur because of physical exhaustion. Oversaturated swimming will affect digestion, which may cause stomach cramps and even vomiting.
2. Avoid swimming after strenuous exercise. Swimming directly after strenuous exercise will increase the burden on the heart, and rushing directly into the water after strenuous exercise will cause a sudden drop in body temperature. At this time, the human body's resistance is weak and it is easy to cause a cold. So don't jump into the water immediately after strenuous exercise.
3. Avoid swimming alone. It is best to choose a crowded place when swimming, so that you can get help in case of an accident. Beginners had better be accompanied by people who can swim.
