When is it not suitable for swimming?

1. If you have just eaten, don't go swimming immediately, which will easily affect your digestive function. When you feel hungry, you can't go swimming, which is easy to cause cramps.

2. Pay attention to measure the water temperature before swimming, because the water is too cold for swimming.

When you swim, you'd better have a companion, a parent as far away from you as possible. If you go out, you can't swim alone.

4. Don't go into the water where swimming is forbidden.

When you go out for an outing, you can find a safe, gentle place where the water is not too cold. If the shore wall is steep and the water is unfathomable, don't rush into the water.

6. If you swim at the seaside, be careful not to be too far away from the shallow water. Even if you are a good swimmer, you should choose a marker on the shore, observe it at any time and determine your position.

7. When swimming, always pay attention to whether there are dangerous obstacles underwater. You can judge whether there are obstacles underwater according to the waves or ripples that appear on the water surface that are different from other places, but sometimes there may be no signs around the obstacles. You must pay attention to this.

When swimming, the water temperature is generally lower than the body temperature, and you may catch a cold. Bathing before entering the water can adapt the body to the water temperature. If you don't get enough sleep, are too tired, or are emotional, you are not suitable for swimming.
