Improving respiratory function Water exercise is very helpful to improve respiratory function. This is because cold water stimulation accelerates the body's metabolic rate. In water, the chest bears the water pressure of 12 ~ 15kg, and the breathing conditions are much more difficult than on land. A large amount of oxygen needed for exercise is obtained by increasing the depth of breathing, so that a large amount of oxygen can be inhaled and a large amount of carbon dioxide can be exhaled every time. After long-term exercise, the respiratory muscles will gradually become stronger and the respiratory function will be greatly improved.
