What are the precautions for playing badminton in summer?

Badminton is a heart-and-soul sport, which can cultivate sentiment, morality and character. What are the precautions for playing badminton in summer? Let me introduce it to you, I hope it will help you!

1, properly hydrated

Badminton sweats a lot and needs to be replenished in time, but if you drink water in the wrong way, it will lead to bad consequences. Many models in beverage advertisements often pick up a bottle of beverage and drink it off during exercise or rest, which seems to quench their thirst. In fact, it is very harmful from the perspective of exercise physiology. Drinking plenty of water during and after exercise will increase the burden on the blood circulation system and digestive system, especially on the heart, causing more fatigue. The result of drinking a lot of water will only be more sweating, leading to further loss of salt, causing convulsions and cramps.

Countermeasures: drink a few mouthfuls of water at a time and drink plenty of water. Don't rely on the feeling of thirst as the basis of hydration, replenish water when you are not thirsty, so that water can be replenished in a balanced way. Don't drink a lot of water at a time, but don't control the replenishment of water. If water loss is not replenished, it will seriously lead to renal failure. Generally speaking, badminton activities (2-3 hours) need at least 1 liter of drinking water, and even 2 liters of water at high temperature. It is recommended to drink sports drinks to supplement the lost trace elements.

2. Prevent heatstroke

In the hot summer, the temperature is high, badminton exercises a lot, and the heat accumulated in the body is more than that emitted. If you don't pay attention to prevention, it's easy to have a fever, ranging from heat exhaustion to heatstroke. Exercise in hot days, in order to lower the body temperature, blood vessels in the skin will expand, and a large amount of perspiration will lead to water loss, and the blood circulating to important parts such as the brain will be reduced to an abnormal level. In this way, the following symptoms will appear: rapid pulse, cold skin, dizziness, weakness and nausea, which is heat exhaustion. If the cooling is not handled in time, the temperature in the body will further accumulate, and the temperature of key organs of the body will rise to dangerous levels, resulting in emergency symptoms: rapid pulse, fatigue, headache, mental state change (fuzzy consciousness or inability to cooperate, slowly falling into a coma), skin fever and flushing, which indicates that heatstroke has occurred, and if it is not handled in time, it will be life-threatening.

Countermeasures: take a rest every 30 minutes at high temperature, and take a rest for 5 ~ 15 minutes according to the specific situation to avoid heatstroke due to fast pulse, high body temperature and excessive sweating. In addition, pay attention to supplement water, salt and electrolyte. If muscle cramps, immediately find a place to rest, massage the cramped area, and slowly stretch the muscles in the cramped area. The most important thing is to replenish water and electrolyte in time.

When there is heat exhaustion, you must rest immediately. It is best to find a cool place, raise the patient's feet and slightly lower his head, immediately replenish water, electrolyte and liquid, and take ten drops of water, Ren Dan, Huoxiang Zhengqi Pill and other heatstroke prevention and cooling drugs.

When heatstroke occurs, it must be treated immediately. The patient may be unable to cooperate because of confusion, so he must be helped to a cool place, and steam cooling method should be used to evenly sprinkle water on the patient's body and head, and keep blowing (it is best to have ice cubes wrapped in a towel and put them on his head to cool down). When the body temperature returns to normal temperature, there is no need to cool down.

But we should continue to observe the patient's body temperature and physical condition, because the body temperature may rise again and need to be cooled again. If the patient has no problem with vomiting reflex and swallowing ability, he can drink cold liquid, supplement water, electrolyte and liquid, and take heatstroke prevention and cooling drugs such as Shidishui, Ren Dan and Huoxiang Zhengqi Pill.

Generally speaking, most patients with heat exhaustion can basically continue to complete the follow-up activities after returning to normal after treatment. Patients with severe heatstroke are advised to find someone to accompany them out of the activity unless they recover well.

3. Avoid catching a cold

Exercise at high temperature in summer, the body produces heat quickly, and the skin capillaries expand a lot, which is beneficial to the body's heat dissipation. If you encounter too cold stimulation, the pores that have been opened on the body surface will suddenly close, leading to dysfunction of internal organs of the body and abnormal temperature regulation of the brain, leading to illness, usually a "cold", that is, a summer cold, or even a more serious disease.

Countermeasures: During the activity, try to avoid the air conditioner blowing directly at the body. It is best to use natural wind to cool down, and then turn on the air conditioner after the body temperature drops. In case of sweating, don't take a cold bath immediately to cool off for a while. Even after the activity, wait until the body temperature drops before taking a cold bath.

4. Proper diet

In summer, if there are iced drinks, it is very pleasant to do physical exercise, but you can't eat a lot of cold drinks during or immediately after the activity. Cold drinks not only reduce the temperature of the stomach, but also dilute the gastric juice, which damages the physiological function of the stomach, ranging from indigestion and diarrhea to acute gastritis.

Countermeasures: a small amount of cold drinks is beneficial to cooling down, but it should not be excessive, and should be treated according to the specific situation. Everyone should drink a small amount of frozen drinks and so on before leaving. After the activity, don't drink frozen drinks or beer until your body temperature drops significantly.

5. Suitable clothes

In summer, outdoor sports sweat a lot, and clothes get wet quickly. Many people often leave their clothes wet and try to dry them by their own body temperature. This is extremely harmful, and in the long run, it will lead to diseases such as rheumatism or arthritis.

Countermeasures: Take several sets of sportswear in your backpack before taking part in the activity, and change wet clothes in time during the activity. In order to facilitate sweat evaporation and heat dissipation, it is best to buy professional clothing.
