What should children pay attention to when swimming in summer?

The hot weather in summer makes people just want to find a quiet place to cool off, but the naughty kids don’t think so. Although the hot sun prevented them from playing outside, the cool water provided them with another open playground. Those who can’t swim are learning, and those who can swim are playing and having fun in the water. However, such play still poses safety risks, and every summer there are always tragedies of people accidentally drowning while swimming. So, what should children pay attention to when swimming in summer?

1. Avoid swimming before or after meals: Swimming on an empty stomach will affect appetite and digestive function, and may also cause unexpected situations such as dizziness and fatigue during swimming; swimming on a full stomach will also affect digestive function, and may also cause stomach cramps, and even vomiting and abdominal pain.

2. Avoid swimming after strenuous exercise: Swimming immediately after strenuous exercise will increase the burden on the heart; the sudden drop in body temperature will weaken resistance and cause colds, pharyngitis, etc.

3. Avoid swimming in unfamiliar waters: When swimming in natural waters, avoid entering the water rashly. It is not advisable to swim in waters where the conditions around and under the water are complicated to avoid accidents.

4. Avoid prolonged exposure to the sun and swimming: Prolonged exposure to the sun will cause sun spots or acute dermatitis, also known as sunburn. To prevent sunburn, it is best to use an umbrella to block the sun after going ashore, or rest in the shade of a tree, or use a bath towel to protect your skin, or apply sunscreen to exposed parts of the body.

5. Avoid swimming without doing warm-up exercises: The water temperature is usually lower than body temperature. Therefore, you must do warm-up exercises before going into the water, otherwise it will easily cause physical discomfort.

6. Avoid eating immediately after swimming: It is advisable to rest for a while before eating after swimming, otherwise it will suddenly increase the burden on the gastrointestinal tract, which may easily cause gastrointestinal diseases over time.

7. Avoid swimming for too long: the skin generally has three reaction periods to cold stimulation. Phase 1: After entering the water, the skin’s blood vessels contract due to the stimulation of cold, and the skin color becomes pale. Phase 2: After staying in water for a certain period of time, the blood flow on the body surface expands, the skin turns from pale to light red, and the skin turns from cold to warm. The third stage: staying too long, the body temperature dissipates more than the heat generated, and goose bumps and chills appear on the skin. This is a taboo period for summer swimming, and you should get out of the water in time. Swimming should generally not last more than 1.5 to 2 hours.

8. People with a history of epilepsy should avoid swimming: No matter it is a major seizure or a minor seizure, there is a moment of loss of consciousness during the seizure. If it is suddenly triggered during swimming, it is inevitable that "disaster" will occur.

9. People with heart disease should avoid swimming: Patients with congenital heart disease, severe coronary heart disease, rheumatic valvular disease, more serious arrhythmia, etc. should stay away from swimming.

10. Avoid swimming when suffering from otitis media: No matter it is chronic or acute otitis media, because water enters the inflamed middle ear, it is like "adding insult to injury", making the condition worse and even causing intracranial infection.

11. Avoid swimming if you have acute conjunctivitis: the virus of this disease spreads at an alarming speed and to a wide range, especially in swimming pools. Even healthy people should avoid swimming in swimming pools during the epidemic season.

13. Avoid swimming when you have certain skin diseases: such as various types of ringworm, allergic skin diseases, etc., which not only induce urticaria and contact dermatitis, but also easily aggravate the condition.

The above precautions are just a drop in the bucket. The only thing that can really keep us safe is our vigilance. We must remain vigilant in any situation. If we encounter any emergency, we can be prepared in the first time to minimize the losses.
