In the hot summer, many people like to go swimming by the river or the sea. Swimming is not only a good way to cool down, but also can help lose weight, enhance immunity, and improve cardiopulmonary function. It is a very popular sport. So no matter the elderly, children or young and middle-aged people, they all like to swim. So what are the precautions for swimming? Let’s go and take a look with the editor!

Swimming is a good way to temper one's will and exercise the body, but swimming also has taboos.

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 during menstruation: Swimming during menstruation may cause bacteria to enter the uterus, fallopian tubes, etc., causing infection, leading to irregular menstruation, excessive menstrual flow, and prolonged menstruation.

4. 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.

5. 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.

6. 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 lead to physical discomfort.

7. 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.

8. 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.

9. 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.

10. Avoid swimming for patients with hypertension: Especially for those with stubborn hypertension which is difficult to control with medication, swimming has the potential risk of inducing stroke and should be absolutely avoided.

11. 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.

12. 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.

13. Avoid swimming when suffering from 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.

14. Avoid swimming when having 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.

15. Avoid swimming after drinking: Swimming after drinking will cause a large amount of glucose stored in the body to be consumed, resulting in hypoglycemia. In addition, alcohol can inhibit the normal physiological functions of the liver, hinder the conversion and storage of glucose in the body, and thus cause accidents.

16. Avoid neglecting hygiene after swimming: After swimming, you should wipe off the scale on your body with a soft dry towel, apply chloramphenicol or boric acid eye drops, and blow out nasal secretions. If water gets into your ears, you can use the "same-side jump" technique to drain the water out. Afterwards, do some relaxing gymnastics and body massage or take a 15-20 minute nap in the sun to avoid muscle stiffness and fatigue.

Although swimming has many benefits, there are also many precautions. If you are sick, it is best not to swim. In addition, it should be noted that if you want to swim, it is best to go to a regular swimming place. Do not violate the regulations in places where swimming is prohibited to avoid accidents and drowning. Safety should always be put first.
