What should I pay attention to in outdoor activities in hot weather?

Sunlight resistance

In summer, we go outdoors or climb mountains. The sun is very strong, so we must pay attention to sun protection!

At noon, 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 penetrate the skin and bones, radiate to the meninges and retina, and cause damage to the brain and eyeballs.

Response measures:

When the weather is hot, you should try to avoid taking the fire belt on the coastline and ridge.

To participate in general activities, you must bring a sun hat, sunglasses, sunscreen, towels, long-sleeved shirts, as well as ten drops of water, Ren Dan, Huoxiang Zhengqi pills, cool oil and other heatstroke prevention drugs.

drink water

We sweat a lot in outdoor sports, so we must replenish water in time. But if you drink water in the wrong way, it will lead to bad consequences. 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.

Response measures:

Less times, only a few mouthfuls of water at a time, and more times of drinking water.

Suggested carrying capacity: more than 4 pieces of 600 ml bottled water, more than 550 ml sports drinks (grape or Gatorade) 1 piece, and 50 g pickled mustard tuber.

Fever (heat exhaustion, heatstroke)

Due to the high temperature and large amount of exercise, the accumulated heat in the body is more than the heat emitted. If you don't pay attention to prevention, it's easy to have a fever, ranging from heat exhaustion to heatstroke. This is very dangerous, fans must pay attention!

Response measures:

When walking in the sun, you can soak your hat in water to help dissipate heat; Walk out of the sun and take off your hat; When resting, try to put down your backpack and untie the neckline of your coat; The best place to rest is in the dark and ventilated place.

Pay attention to the rhythm when marching. Each walk should not exceed 1 hour, rest for about 30 minutes at high temperature, and rest for 5 ~ 15 minutes according to specific conditions to avoid heatstroke due to rapid pulse, high body temperature and excessive sweating.

In addition, we must pay attention to replenish water, salt and electrolyte along the way, and bring heatstroke prevention drugs.

heat and cold

"Hot cold", that is, summer cold, will cause visceral dysfunction, abnormal brain temperature regulation, leading to illness.

Response measures:

On the way to March in summer, when sweating profusely, if there are mountain springs, streams, ponds, etc. Or passing by the seaside, don't jump down and take a cold bath for a while.

After the activity, after arriving at the destination, wait for the temperature to drop before taking a cold bath.

After the event, if everyone's return car is air-conditioned or in an air-conditioned room, don't turn on the air conditioner and blow directly at the car body. It is best to open the window to cool down with natural wind, and then turn on the air conditioner after the body temperature drops.

cooling beverage

On such a hot day, it is very enjoyable to have iced drinks, but you can't eat a lot of cold drinks during or immediately after the activity.

Cold drinks can damage the physiological function of the stomach, from indigestion and diarrhea to acute gastritis.

Response measures:

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.

clothes

The most annoying thing in summer is sweating a lot after exercise, and clothes get soaked quickly. ...

Most of us often let our clothes get wet and try to dry them through our own body temperature. This is extremely harmful!

In the long run, it will lead to diseases such as rheumatism or arthritis.

Response measures:

Take a set of dry clothes (especially a coat) and a coat in your backpack before taking part in the activity, and change your wet clothes immediately after you arrive at your destination.

When resting during activities, if the wind is strong, if you rest for a long time, you should put on your coat in time, otherwise the wind will take away a lot of body heat, and people's body will be hot and cold alternately, which is easy to cause diseases.

In order to facilitate sweat evaporation and heat dissipation, it is best to buy quick-drying clothes made of chemical fiber for outdoor activities, preferably quick-drying anti-ultraviolet clothes, and it is best to remove the trouser legs.
