Who is the main culprit for the damage to health caused by swimming

People feel very comfortable when swimming, so they like to swim in these specific places in summer. However, there are still many dangers when swimming, so relevant safety measures need to be taken.

What are the taboos when swimming? Today I will list these taboos one by one.

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.

Children need to be supervised by adults when swimming to avoid the risk of drowning. In addition, swimming for a long time can indeed help with weight loss, but you need to pay attention to whether your own conditions are suitable.
