How to swim is healthy and safe, and what are the precautions for safe swimming?

First of all, outdoor swimming is different from indoor swimming. But one thing is the same, that is, there must be preparatory activities. Especially in summer, the difference between air temperature and water temperature is still relatively large, so in order to avoid discomfort after entering the water, it is best to warm up first.

Second, although summer is suitable for swimming, we should also pay attention to the length of time. Swimming for a long time will lead to excessive body temperature loss and cause physical discomfort.

When swimming outdoors, it should be noted that you should not swim in the river at will in unfamiliar places, mainly for safety reasons. There is also outdoor swimming, and you need to pay attention to sun protection. Strong sunlight can cause skin problems. So take sunscreen, dry yourself with a dry towel after swimming and then apply sunscreen.

Pay attention to swimming time. You can't swim immediately before and after meals, because swimming on an empty stomach will reduce your appetite, and swimming just after meals will cause digestive problems.

You must pay attention to hygiene after swimming. Besides taking a bath, we should also remove secretions from the mouth, ears and nose. Otherwise, it is easy to cause health problems.

Warm-up before the activity is essential! Be sure to do warm-up exercises before entering the water, such as stretching your arms and leg press, expanding your chest and so on. It is best to stimulate the body with water before entering the water. A good body will adapt to the water quickly during the transition and will not cramp easily.

Even if you swim in a safe swimming pool, you should be careful not to swim alone. Children should go into the water under the supervision of adults. Many swimming pool accidents are caused by parents' negligence. Children play with water by themselves, but they can't swim and fall into the pool to call for help. Therefore, it is best to let children play with water under the care of adults.

Swimming is also an energy-consuming exercise, so don't swim immediately on an empty stomach, or you will feel exhausted and even collapse. At the same time, don't eat too much and go swimming right away. Doing such exercise after eating too much will make your stomach uncomfortable and easily cause vomiting. It's best to wait for two hours after dinner before going swimming.
