What are the taboos of swimming in summer

1. 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 the resistance and cause colds, pharyngitis, etc.

2. Avoid prolonged exposure to the sun and swimming

Prolonged exposure to the sun can cause sun spots or acute dermatitis, also known as sunburn. To prevent sunburn, it is best to use an umbrella to shade yourself 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 areas of your body.

3. Avoid swimming without warm-up exercises

The water temperature is usually lower than body temperature, so you must do warm-up exercises before entering the water, otherwise you may feel uncomfortable.

4. 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.

5. Avoid swimming for too long

The duration of swimming should generally not exceed 1.5 to 2 hours, which is determined by the three reaction periods of the skin 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.

6. 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.

7. Avoid swimming during menstruation

If you swim during menstruation, bacteria can easily enter the uterus, fallopian tubes, etc., causing infection, leading to irregular menstruation, excessive menstrual flow, and prolonged menstruation.

8. Avoid swimming in unfamiliar waters

When swimming in natural waters, avoid jumping into the water rashly. It is not advisable to swim in waters where the conditions around and under the water are complicated to avoid accidents.

9. Avoid swimming on an empty stomach

Many people who love swimming have a feeling that after swimming ashore, they feel hungry and weak. This is because swimming is a strenuous sport that involves large range of motion of the limb muscles and consumes a large amount of energy and calories from the human body.

If you go swimming on an empty stomach, due to low blood sugar in the body, you are particularly prone to muscle tremors, dizziness, collapse, coma, and may even drown.

Therefore, swimmers should consume some fruit, milk, candy and other foods before swimming.

10. Avoid swimming after drinking

Many people who love swimming, after drinking with friends, jump into the water to swim just to cool down. In fact, it's downright dangerous.

Because after people drink, alcohol will stimulate the brain, causing confusion and loss of control over their actions. If they cannot control their actions after going into the water, it is very likely to cause extremely serious adverse consequences.
