What should I pay attention to when swimming?

Swimming is a very beneficial activity, but it is also dangerous. To ensure safety, we should do the following:

1, swimming requires a physical examination. People suffering from heart disease, hypertension, tuberculosis, otitis media, skin diseases, severe trachoma and various infectious diseases are not suitable for swimming. Menstrual female students are also not suitable for swimming.

2. Choose the swimming place carefully. To swim in rivers, lakes and seas, we must first understand the water conditions. Waters with more undercurrents, eddies, silt, rocks and aquatic plants are not suitable for swimming. It is also not suitable to swim in the waters where there are many ships coming and going, polluted and schistosomiasis endemic areas.

3. Preparation before launch. You can run, do exercises, exercise, and wash your trunk and limbs with a small amount of cold water, so that your body can adapt to the water temperature as soon as possible and avoid dizziness, palpitation and cramps.

When you are full or hungry, don't swim after strenuous exercise and hard work.

5. Don't dive when the underwater situation is unknown.

6. If you find someone drowning, don't rush into the water for rescue. You should call an adult to help.

Matters needing attention in swimming and paddling

Before you get close to the stream, you must get the consent of your family in advance, and at the same time stay together and take care of each other.

● Do not swim in water with warning signs such as "No swimming or dangerous water depth".

● Do not swim or play in waters, streams, branches or lakes with unknown terrain to avoid danger.

● When you are in poor physical and mental state, such as fatigue, satiety, hunger, illness, bad mood, drunkenness, etc., you should not play in the water.

● Unexplained stream topography or water depth is not suitable for diving.

People with poor diving skills should not dive into deep water rashly, so as not to endanger their lives.

● Wear life jackets to ensure safety when engaging in any water activities.

● Go into the water without jeans or pants.

If you see someone drowning, you should shout for help. Don't save yourself if you are not skilled in life-saving technology.

● Rivers and streams often have undercurrent eddies because of the high mountains and high water, the rapidness of rivers and streams and the steep slope of the river bottom. If tourists are not familiar with the underwater situation, rush into the water or ignore the hidden dangers in the vast waters, they are likely to pay a great price.
