The following "National Standard Network" will introduce the taboos for swimming in the hot summer.
Notes on swimming
1. Avoid swimming before and after meals: Swimming on an empty stomach can affect appetite and digestive function, and unexpected situations such as dizziness and fatigue can also occur during swimming; swimming on a full stomach can also affect digestive function, causing stomach cramps, and even vomiting and abdominal pain.
2. Avoid swimming after strenuous exercise: Swimming immediately after strenuous exercise can add to the burden on the heart; a sharp drop in body temperature can weaken resistance, causing colds, sore throat, etc.
3. Avoid swimming during menstruation: Swimming during menstruation can easily cause bacteria to enter the uterus, fallopian tubes, etc., causing infection, causing irregular menstruation, excessive menstruation, and prolonged menstruation.
4. Avoid swimming in unfamiliar waters: When swimming in natural waters, avoid rushing into the water. Where the surrounding and underwater conditions are complicated, it is not advisable to swim in the water to avoid accidents.
5. Avoid swimming in the sun for a long time: Prolonged exposure to the sun can cause sunburn, or cause acute dermatitis, also known as sunburn. To prevent the occurrence of sunburn, it is best to use an umbrella to shade the sun after going ashore, or rest in a shady place, or use a bath towel to protect the skin on the body, or apply sunscreen on the exposed part of the body.
6. Avoid swimming without doing preparatory activities: the water temperature is usually lower than the body temperature, so you must do preparatory activities before entering the water, otherwise it will easily lead to physical discomfort.
7. Avoid eating immediately after swimming: After swimming, it is advisable to rest for a while before eating, otherwise it will suddenly increase the burden on the stomach and intestines, and it is easy to 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, it is stimulated by cold, the skin blood vessels constrict, and the skin tone is pale. Phase 2: After staying in the water for a certain period of time, the blood flow on the surface of the body expands, the skin turns from pale to light red, and the skin turns from cold to warm. Phase 3: If you stay in the water for too long, the body temperature will dissipate more than the heat, and the skin will have goosebumps and chills. This is a taboo period for summer travel, and you should get out of the water in time. Swimming duration should generally not exceed 1.5 to 2 hours.
9. Avoid swimming with a history of epilepsy: Whether it is a major seizure or a minor seizure, there is a momentary loss of consciousness during the seizure. If it is suddenly induced during swimming, it will inevitably be "catastrophic".
10. Avoid swimming in patients with hypertension: especially stubborn hypertension, which is difficult to control with medication. Swimming poses a potential risk of stroke and should be avoided.
11. Avoid swimming for people with heart disease: such as patients with congenital heart disease, severe coronary heart disease, rheumatic valve disease, and more serious arrhythmias, swimming should be "kept away".
12. Avoid swimming with otitis media: Whether it is chronic or acute otitis media, water entering the inflamed middle ear is equivalent to "making things worse", making the condition worse and even causing intracranial infections.
13. Avoid swimming with acute conjunctivitis: The speed and scope of the virus, especially in swimming pools, are surprising. Even healthy people should avoid swimming in swimming pools during the epidemic season.
Emergency treatment method:
1. What should I do if my ears get wet?
Tilt your head to the side where the water enters the ear, pull the earlobe with your hands, and perform a one-legged jump with the same leg; align the palm of your hand with the ear plug and press it tightly, tilt your head to the side where the water enters the ear, and then quickly push your hands away. According to the Nanning Evening News, if you have symptoms such as pain and tinnitus after the ear enters the water, you need to go to the hospital for examination.
2. What should I do if I get entangled in aquatic plants?
Use the backstroke method to slowly return along the original road; lie flat on the water surface, so that the legs are separated, and release with your hands; if you have a knife with you, you can cut off the aquatic plants with a knife; try to kick the aquatic plants away, or remove the aquatic plants from your hands and feet like taking off your socks. After getting rid of the aquatic plants, swim gently by kicking your legs and leaving the place where the aquatic plants grow as soon as possible. When you can't get rid of them, call for help in time.
3. Self-rescue
Do not assume that a person who can swim will not drown. If drowning occurs, you should first stabilize your emotions, relax your body, and naturally relax your limbs to droop, leaving your head and back of your neck above the water until you can breathe.
4. Rescue
If you see someone drowning, you should not rush into the water to rescue them. Instead, you should call for help loudly and throw floating objects, such as life buoys, water boards, foam boards, etc., in time to let the drowning person float in the water. Approach the rescue from behind the drowning person. If the drowning person is unconscious after rescue, you should rescue them as quickly as possible. Turn your head sideways, pry open your mouth to clear the debris in your mouth and nose, and then press the water in the drowning person's abdomen with both hands to discharge, perform cardiopulmonary resuscitation or artificial respiration.
5. Drowning people go ashore to recover
After a drowning person is rescued ashore, they must promptly perform on-site rescue or transfer to the hospital while rescue, such as dialing 120 immediately to help them quickly drain the stagnant water, clear the respiratory tract, and use artificial respiration to help them recover their heartbeat.
6. What should I do if my hands and feet cramp?
If cramps occur during swimming, if it is a finger cramp, you can make a fist, then open it with force, and quickly repeat it several times until the cramp is eliminated. According to Aishang.com, if it is a calf or toe cramp, first take a breath to float on the water, hold the toes of the cramped limb with the hand on the opposite side of the cramped limb, and pull it hard in the direction of the body. At the same time, press the palm of the same side on the knee of the cramped limb to help the cramped leg straighten.
