Many parents of children with asthma try to keep their children from participating in sports as little as possible, thinking that this will prevent asthma attacks, but in fact, this will make their cardiorespiratory function worse and even have an impact on the children’s self-confidence. Some studies have pointed out that moderate and gentle sports can not only make the body healthier, but also improve the body’s resistance, promote blood circulation and metabolism, improve respiratory and cardiopulmonary function, relieve asthma, and facilitate the treatment and recovery of asthma patients. Moderate swimming and water fitness activities are most suitable for mild to moderate patients and can effectively improve their condition. A survey in 2000 found that 71% of asthma patients had varying degrees of improvement through moderate exercise, and the proportion of asthma patients requiring treatment and hospitalization had decreased. Swimming for children is indeed very helpful in the treatment of asthma. After two months of swimming training, 70% of children with asthma experienced a significant decrease in the frequency of attacks and a reduction in the symptoms of asthma attacks. Some children even never had an asthma attack after the training. Swimming in the water can relieve asthma attacks The benefits of exercising in the water have also been confirmed by the medical community and are widely used as an adjunct to asthma treatment. Aerobic swimming and hydrotherapy are good exercises for the swimmer’s body or for asthma, and do not cause the injuries associated with high-pressure exercise. The weight of the body is supported by the buoyancy of the water while in the water and the strain and stress on muscles and joints is reduced. In addition, the range and freedom of movement of the body is increased when exercising in water, and the stress on muscles, bones, joints and spinal cones is lower than in other sports. The controlled breathing pattern of the swimming process is exactly the kind of stress-free breathing exercise that asthma patients need. Asthma patients often suffer from asthma due to respiratory irritation after inhaling cold air, while the air is more humid during swimming, and as long as the temperature is suitable, it will not cause irritation to the respiratory tract. In addition, the density of water is hundreds of times greater than air, when inhaling in water, the respiratory muscle burden is increased, about 12-15 kg of water pressure compressing the entire thoracic cavity, which provides favorable forging conditions for the function of the human respiratory system, and can effectively forge the pectoral muscles, diaphragm and intercostal muscles, improve the ventilation function of the lungs, and strengthen the cardiopulmonary function. Enhance the immune ability regular swimming can improve the nervous system’s ability to regulate body temperature, improve the body’s adaptation to climate changes in cold and heat, reduce the chance of colds, improve the physical quality of children and the body’s ability to resist disease, and reduce asthma attacks. Studies have pointed out that swimming for half an hour a day for a season can increase lung capacity by 500 ml. Precautions for swimming exercise for asthma patients 1. The intensity of swimming exercise must be gradual. You should pay attention to keeping warm during swimming, pay attention to warming up well before going into the water, and you should also take a hot bath in time after swimming. 2, pay attention to the pool disinfection is standardized. Many swimming pools will add a large amount of disinfectant in the disinfection process, once the disinfectant is excessive, it may produce a large amount of chlorine, and asthma patients, many patients have allergic rhinitis, swimming process, chlorine will stimulate allergic rhinitis attacks, which further induces asthma attacks. 3.When you feel difficulty in breathing, heartache, or make a “hip” sound when breathing during exercise, you should stop exercising and spray asthma relievers. 4.Patients with severe asthma, such as those who feel shortness of breath even when walking, and whose asthma keeps recurring and does not improve for several weeks, are not suitable to do exercise. 5, for special asthma patients, can be appropriate under the guidance of doctors to take drugs to prevent asthma when swimming. Asthma patients must be accompanied by someone when swimming, especially children with asthma. Once the discomfort occurs, be sure to go ashore in time to rest and adjust or end this swim.
