The summer solar term is the hottest season in a year. The following is a collection of health precautions for the big summer solar terms for your reference only!
Precautions for keeping in good health in summer 1. Wear cotton clothes.
Wearing light-colored clothes in summer can reduce the heat absorption of the clothes team, so it is cooler to wear; Dark clothes, on the other hand, will absorb more heat, which will make people sultry.
Cotton fabrics are superior to chemical fiber products in heat absorption and sweat absorption. Therefore, it is best to wear light-colored cotton in summer sports clothes. The looser the style, the better the heat dissipation performance, and the lighter the color, the less likely it is to absorb heat.
2. It is not advisable to do morning exercises too early.
Dawn is 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, the ultraviolet and infrared rays are strongest from 1 1 to 4: 00 pm every day. Excessive ultraviolet rays can cause damage to skin and eyes and cause skin cancer. However, long-term exposure to infrared rays can increase the intracranial temperature, cause inflammation of meninges, and cause sunstroke. Therefore, we should try to avoid exercising outdoors when the sun is strongest, and we should not exercise naked.
4. Control the intensity of exercise
The human body consumes a lot of energy in summer, so it is necessary to control the intensity 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 you have dizziness, headache, nausea, vomiting and other symptoms, you can take summer-heat drugs such as Rendan and Shidishui. If you still don't get better after treatment, you should go to the hospital immediately.
5. Timely and appropriate hydration.
In summer, people sweat a lot and lose a lot of salt, which easily reduces the osmotic pressure of cells, leading to sodium metabolism disorder and cramps. Therefore, it is very important to replenish water in time during summer exercise. It is best to replenish water several times, and drink water every 10 to 15 minutes 150 to 200ml during exercise. But don't drink too sweet drinks to avoid increasing the burden on your 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.
6. Don't use cold drinks to cool down
Some people are used to eating cold drinks after exercise. In fact, eating cold drinks at high body temperature will harm the stomach. This is because a lot of blood rushes to muscles and body surface during exercise, while the digestive system is in a state of relative anemia. At this time, eating a lot of cold drinks will not only reduce the temperature of the stomach, but also dilute the gastric juice, which will damage the physiological function of the stomach. In light cases, it will cause acute gastroenteritis such as indigestion, vomiting, diarrhea and abdominal pain, and in severe cases, it may lay a curse for chronic gastritis and gastric ulcer in the future. Warm and dilute salt water is the best drink after exercise.
7. Don't take a shower immediately
After full exercise, the human body will sweat profusely and the pores of the whole body will be opened. If you suddenly pour cold water on your body at this time, it will cause a cold and fever. And taking a shower can't help the muscles relax, but it will make the muscles more nervous. The correct way is to wait until the sweat on your body is dry, and then take a shower with warm water. The water temperature should be higher than the body temperature1~ 2℃.
