Swimming is a sport suitable for all seasons. Although the weather gradually turns cooler after the beginning of autumn, maintaining a good habit of swimming can still effectively improve your health.

When swimming, due to the resistance of water, the muscles of the chest, back, buttocks, and legs of the human body can be well exercised. When exercising in the water, the heat quickly dissipates, which can prevent from gaining weight in autumn.

In addition, when swimming, the cold water stimulates the skin blood vessels to contract, and a large amount of blood flows back to the deep tissues and internal organs, which enhances the elasticity of blood vessels and improve the immunity. However, due to the cool weather in autumn, compared with swimming in summer, it is necessary to pay attention to the following preparations and precautions to avoid accidents.

Precautions

1. Prepare well. It is recommended to take a shower with normal temperature water to adapt to the cooler water temperature before entering the water. At the same time, adequate warm-up exercises should be done to stretch out and avoid cramps due to the cold water.

2. Swimming is prohibited in special circumstances. It is best to avoid swimming if you have a cold, feel fatigued, are physically uncomfortable, or have just eaten. In addition, swimming should be avoided after strenuous exercise, because it will increase the burden on the heart and sharply reduce body temperature, which will weaken immunity and induce colds, pharyngitis, etc.

3. Pay attention to safety and try to avoid swimming alone to avoid accidents. Children should be accompanied by adults. People who could not swim must be accompanied by other people and stay in shallow water areas.

4. The time should be appropriate and keep warm. The time in the water should not be too long. 45 to 60 minutes is appropriate. After getting out of the pool, be sure to dry off immediately and take measures to stay warm.

5. Do not eat immediately after swimming. It is recommended to avoid eating immediately after swimming. It is necessary to rest for a while before eating, otherwise it may suddenly increase the burden on the gastrointestinal tract, which will easily cause gastrointestinal diseases over time.
