What should you pay attention to when doing outdoor activities in hot weather?
Sun protection
When we travel outdoors or climb mountains in summer, the sun is quite strong, so be sure to pay attention to sun protection!
The temperature is the highest at noon, and the sun is like fire. The ultraviolet rays in the sun are particularly strong. If the skin is exposed to the scorching sun for a long time, it will cause 1 to 2 degree burns and heat stroke.
Ultraviolet rays can also penetrate skin and bones and radiate to the meninges and retina, causing damage to the brain and eyeballs.
Countermeasures:
In hot weather, you should try to avoid taking fire breaks along the coastline and ridges.
When participating in general activities, be sure to bring a sunhat, sunglasses, sunscreen, towel, long-sleeved top, and heatstroke prevention medicines such as Ten Dishui, Rendan, Huoxiang Zhengqi Pills, and Cooling Oil.
Drinking water
We sweat a lot during outdoor exercise and must replenish water in time. But if you drink water in the wrong way, it will cause adverse consequences. Drinking a lot of water during and after exercise will increase the burden on the blood circulation system, digestive system, especially the heart, causing more fatigue. The result of drinking a lot of water will only be more sweating, which will lead to further loss of salt and cause cramps and cramps.
Countermeasures:
Drink water in small amounts and often, only a few sips each time, and drink water more frequently.
Recommended amount to carry: more than 4 bottles of 600 ml bottled water, more than 1 550 ml sports drink (Grape Suit or Jade), and 50 grams of mustard.
Heat illness (heat exhaustion, heat stroke)
Due to the high temperature and heavy exercise, the body accumulates more heat than it dissipates. If you don’t pay attention to precautions, it is easy to develop heat. Heat illness can range from mild heat exhaustion to severe heat stroke (that is, heat stroke). This is very dangerous, so fans must pay attention!
Countermeasures:
When walking in the sun, you can soak the hat with water to help dissipate heat; When walking in areas not exposed to sunlight, remove your hat; when resting, try to put down your backpack and unbutton the collar of your jacket; the best place to rest is out of the sun and out of the way of ventilation.
Pay attention to your rhythm during the march. You should not walk for more than an hour at a time. Take a break every 30 minutes in high temperature conditions, and rest for 5 to 15 minutes depending on the specific situation to avoid excessive pulse, high body temperature and excessive sweating. Cause heat stroke.
In addition, you must pay attention to replenishing water, salt and electrolytes along the way, and bring all heatstroke prevention medicines.
Heat cold
"Heat cold" is also a summer cold. If you encounter super cold stimulation when it is very hot, it will cause dysfunction of the internal organs in the body and abnormal brain temperature regulation. Cause illness.
Countermeasures:
When you are sweating profusely while marching in summer, if there are mountain springs, streams, ponds, etc., or passing by the seaside, you must not be greedy for a moment of coolness. Jump in and take a cold shower immediately.
After the activity is over and you arrive at your destination, you should wait for your body temperature to drop before taking a cold shower.
After the event, if the vehicle you are returning to is an air-conditioned vehicle or is in an air-conditioned room, be sure not to turn on the air conditioner and blow it directly on your body. It is best to open the car windows and let the natural wind cool down, and wait until the body temperature drops. Turn on the air conditioner after you get down.
Cold drinks
On such a hot day, it would be a great pleasure to have iced drinks~ However, during or after the event, do not drink a large amount immediately Eat cold drinks.
Cold drinks can damage the physiological functions of the stomach, causing indigestion and diarrhea in mild cases, and acute gastritis in severe cases.
Countermeasures:
A small amount of cold drinks is beneficial to cooling, but it cannot be excessive and should be treated according to the specific situation.
Everyone should drink the frozen drinks etc. in small amounts and frequently before departure.
After the activity, wait until the body temperature has dropped significantly before drinking frozen drinks or beer.
Clothes
The most annoying thing in summer is sweating a lot after exercise, and the clothes will get soaked quickly...
Most of us tend to let our clothes go. Wet, trying to dry the clothes with their own body heat. Doing so is extremely harmful!
In the long run, it will cause diseases such as rheumatism or arthritis.
Countermeasures:
Before participating in the activity, bring a set of spare close-fitting dry clothes (especially a top) and a jacket in your backpack. When you arrive at your destination, put them on immediately Change out of wet clothes.
When resting during activities, if the wind is very strong, if the rest time is long, you should put on a coat in time, otherwise the wind will take away a lot of body heat, and the human body will become cold or hot. Alternately, it is easy to cause disease.
In order to facilitate sweat evaporation and heat dissipation, it is best to buy quick-drying clothing made of chemical fiber for outdoor activities. The best ones are quick-drying and UV-resistant clothes. It is best to have removable trouser legs.
