Eleven things to note when swimming in summer

In the hot summer, many people choose to swim to cool down. Swimming can not only help you lose weight and shape your body, but also exercise your muscles, increase blood circulation and improve your immunity. However, swimming enthusiasts should also pay attention to the following points when swimming in summer, which will not only entertain the body and mind but also provide themselves with a safe protection.

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 the 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 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 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.

6. 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.

7. Avoid swimming if you have a history of epilepsy : Regardless of whether it is a major seizure or a minor seizure, there is a moment of loss of consciousness during the attack. If it is suddenly triggered while swimming, it is inevitable that "disaster" will occur.

8. 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.

9. 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.

10. Avoid swimming after drinking : Swimming after drinking will consume a large amount of glucose stored in the body and cause 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.

11. 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.

The above are eleven things that the editor has summarized for swimming in summer. Do you understand them? Swimming is indeed good for your health, but you should choose according to your physical condition.
