At this time, the temperature is the highest, the sun is like fire, and the ultraviolet rays in the sun are particularly strong. If the skin is exposed to the hot sun for a long time, it will cause burns of 1~2 degrees, and heatstroke will occur. Ultraviolet rays can also radiate to the meninges and retina through the skin and bones, causing damage to the brain and eyeballs. So try not to do outdoor sports at noon in summer.
2. Rescue measures
Immediately move to a cool and ventilated place. Unbutton your clothes and have a quiet rest. Only those who are 1 trillion or lighter can be given cool salty drinks, oral Ren Dan, ten drops of water and so on. For those who are suspected of circulatory failure, glucose saline should be given intravenously as appropriate. Patients with spasticity can take salty refreshing drinks orally or drip glucose saline intravenously, or slowly inject 10% calcium gluconate 10~20ML intravenously. Those with circulatory failure should replenish water and expand capacity as soon as possible to correct circulatory failure. High fever type: rapid cooling: wipe the body with a fan, cold water, ice water or alcohol until the skin turns red, and apply ice packs to the head, neck, armpits and groin. You can also immerse the patient's head in 4-degree water and continuously massage the skin of the limbs to keep the respiratory tract unobstructed.
3. What should I do if I faint from outdoor sports?
In order to avoid heat fainting, some climbers with weak systems should pay special attention to avoid activities that consume excessive physical strength, pay attention to the rest rhythm and maintain their physical strength when participating in summer mountaineering activities. Drink plenty of water or salty drinks, even if it is to supplement the electrolyte loss in the body.
In case of heat fainting, the patient should be transferred to the shade and lie down as soon as possible. If the patient is conscious, let him drink some cold water slowly. If the patient sweats a lot, or has cramps, diarrhea, vomiting and other symptoms, salt should be added to the water (one teaspoon per liter). If the patient has lost consciousness, he should lie down in prone position and have a full rest until the symptoms are alleviated, and be sent to the hospital for further treatment.
Precautions for outdoor sports in summer Avoid high humidity sports.
In summer, we should keep a low amount of exercise and a short time to adapt our bodies to the heat. Outdoor sports should be avoided when the sun is strong from noon to 2 pm. At this time, strong ultraviolet rays will burn the skin and irritate the eyes.
Choose clothes that absorb sweat.
Summer sports must choose to wear sweat-absorbent cotton shirts, not tight sportswear. If sweat can't be discharged in time, it will affect heart health. In addition, you should also prepare a set of dry clothes and change them in time after exercise, otherwise it will cause rheumatism or arthritis.
Replenish water in advance
Summer exercise dehydrates the body. It is recommended to drink 800 ml of water half an hour before exercise. If you are outdoors for a long time, order a bottle of water, preferably supplemented with salt.
Reasonable food intake
Eat this staple food or fruit one hour before exercise. This is to prevent the intake of calories is too low, leading to poor physical strength.
Don't drink too much water
Drinking plenty of water after exercise will increase the burden on the blood and digestive system and make you more tired. In addition, drinking more water will make the salt loss faster, which is easy to cause convulsions and cramps. It is recommended to drink a little more.
