1, wear cotton-padded jacket.
Light-colored clothes can reduce the absorption of heat and make them cooler to wear; Dark clothes will absorb more heat energy, which makes them sultry. Cotton fabric is superior to chemical fiber products in heat absorption and sweat absorption. So light cotton is the best sportswear in summer. The looser the style, the better the heat dissipation performance, and the lighter the color, the less likely it is to absorb heat.
2, morning exercises should not be too early.
Dawn comes early in summer, and many people who have the habit of doing morning exercises go out to exercise at dawn. But morning exercise should not be too early, so as not to affect normal sleep.
Step 3 avoid direct sunlight
In summer, ultraviolet and infrared rays are strongest every morning 1 1 to 4 pm. Excessive ultraviolet rays can cause damage to the skin and eyes, causing skin cancer. However, long-term exposure to infrared rays will increase the intracranial temperature, cause meningitis and heat stroke. So try to avoid outdoor sports when the sun is strongest, let alone naked sports.
4. Control the intensity of exercise
In summer, the human body consumes a lot of energy, so the intensity should be controlled during exercise. Once you have symptoms of heatstroke, you should immediately sit down in a cool and ventilated place, drink some cold salt and boiled water, breathe fresh air, and apply cold compress to your forehead or armpit. When dizziness, headache, nausea, vomiting and other symptoms appear, you can take Ren Dan, Shidishui and other summer drugs. If you still don't get better after treatment, you should go to the hospital immediately.
5, timely and appropriate hydration
Sweating too much in summer, salt loss, easy to reduce cell osmotic pressure, leading to sodium metabolism disorder, cramps. Therefore, it is very important to replenish water in summer exercise in time. It is best to replenish water several times, and drink 10 to 15 minutes 150 to 200ml during exercise. But don't drink too sweet drinks, so as not to increase the burden on the stomach. You should also replenish water in time after exercise, but don't drink too much at a time, binge drinking will increase the burden on your heart.
