What are the dangers of outdoor activities?

There are many uncontrollable factors in outdoor activities. The geographical environment, intensity and danger of different activities are different, and the requirements for participants' physical quality and psychological quality are also different. But as an outdoor enthusiast, are you really ready for everything? Follow me to get to know it.

What are the dangers of outdoor activities 1 1? What are the dangers of outdoor activities? Dangers in the process of mountain climbing.

The area where avalanches are easy to occur is called avalanche area. When an avalanche occurs, the snow slides down a channel called an avalanche trough, leaving obvious traces; At the same time, avalanche deposition appears in the lower part of the avalanche trough. Avalanches usually occur within 2 ~ 3 days after heavy snow, mostly at the highest temperature time of the day 10 from morning to 2 pm. Therefore, when choosing specific road sections, we should try to avoid the avalanche area.

Ice collapse. Ice collapse occurs at the end and sides of suspended glaciers, ice towers, ice cliffs and so on. It is called an ice avalanche, which is caused by gravity, wind, melting and glacier flow. Ice collapse often occurs in high temperature season, when the temperature is the highest every day. The characteristics and identification of ice avalanche area, the prevention and rescue of ice avalanche are similar to those of avalanche.

Rolling StoneA rolling stone is called a rolling stone because it is broken by weathering and rolled down the mountain under the action of gravity and wind. This kind of danger, especially in mountainous areas without vegetation cover, is easy to happen. The area where a rolling stone occurs is called the rolling stone area. Another feature of the rolling stone area is that there are a lot of deposits in its lower part, and there are generally traces of rolling stones passing through the upper part of the deposits.

2. What are the dangers of outdoor activities: the danger of surfing.

Marine life. Sharks are the most common marine creatures that attack surfers. In fact, there are not many incidents in which sharks attack surfers every year. On the contrary, two kinds of creatures, such as sea urchins and jellyfish, always accompany surfers. Most surfers should have been stung by jellyfish, and the severity can be suitable for people or fatal.

Ordinary drowning events are rare among ronin. After all, there are surfboards around. On the contrary, ronins often play the role of lifeguards to save drowning people. But if the waves are big and the surfboard is washed away, there is a high possibility of drowning. When surfing, you'd better get into the water with your friends. In case of emergency, someone can help you.

Waves. Waves can be beautiful and gentle, or ugly and fierce.

Undercurrent Undercurrent is fatal to surfers and swimmers. Undercurrent can make you drift away in minutes. In fact, most swimmers don't know how to deal with the undercurrent in the sea, and the resulting panic is the main reason for drowning.

3. What are the dangers of outdoor activities? The dangers of swimming in the wild.

Swimming outdoors is much more dangerous than swimming in the swimming pool.

In an emergency, such as cramps and exhaustion, it is very dangerous to speak without others present. Therefore, you must have a few people who are good at water.

The river looks calm, but the situation under the water is not necessarily the case. There may be eddies, weeds, or other hard things. If the injury is not handled properly, it is easy to suffocate.

The temperature difference between water, water surface and underwater in the wild environment is very large, which is easy to cause cramps, dizziness and physical discomfort, and the potential danger is great. If you plan to cross the river, it is recommended to be accompanied by many people, make full preparations before swimming, and prepare protective facilities. If you feel unwell, don't cross the river by force, use life-saving equipment and return with the help of accompanying personnel. Finally, it is recommended not to swim in the river.

Precautions for mountaineering

1. Mountain climbing is good for people's physical and mental health, but it is also dangerous. In order to ensure safety, we should do the following:

2. When climbing the mountain, teachers or parents will lead you, so you should act in groups.

3. Choose the place of climbing carefully. It is necessary to learn about the local geographical environment and weather changes from nearby residents, choose a safe mountaineering route, and mark it well to prevent getting lost.

4. Prepare sports shoes, ropes, dry food and water. Be sure to bring enough water in summer, because climbing mountains will make you sweat. If you don't add enough water, you will easily collapse and get heatstroke.

5. It is best to carry first-aid drugs with you, such as anti-hyperreflexia drugs, Yunnan Baiyao, hemostatic bandages, etc. In order to come in handy when hyperreflexia, falls, bumps and sprains.

6. It is best to climb the mountain in the morning or in the morning and return to the station in the afternoon. Don't change the climbing route and time without authorization.

7. Don't carry a backpack, but carry it on your shoulders, so that you can grasp it with both hands. You can also use a strong long stick as a crutch to help you climb.

8. Never take pictures on dangerous cliffs to avoid accidents.

9. For group mountaineering, you can buy short-term group travel accident insurance by yourself.

What are the dangers of outdoor activities 2 1 and lack of water on the way?

You will die of thirst first, not starvation.

In outdoor sports, a large amount of perspiration will lead to a large loss of water, salt and electrolyte in the body. If it is not replenished in time, it will cause electrolyte disorder in the body, leading to heatstroke or collapse.

Tip:

1, activities should carry enough drinking water according to the weather and route.

2, should reserve 500ml of emergency drinking water in case of emergency.

3. Take the initiative to replenish water, don't wait until you are thirsty.

4. During the activity, we should follow the principle of replenishing water to avoid drinking a lot of water at one time to increase the burden on the heart.

2. Outdoor heatstroke

The consequences are more important than you think.

If we do outdoor sports in summer, with the temperature rising, it will cause a series of adverse reactions, especially heatstroke, which may threaten our lives in severe cases.

When there is a contradiction between ultraviolet protection and heat dissipation and perspiration, we should take the lesser of the two evils and give priority to heat dissipation and perspiration. In fact, this contradiction is not difficult to solve. A bottle of sunscreen can resolve conflicts to a great extent.

Tip:

1, wearing red (lowest infrared absorption), good heat dissipation and perspiration effect, professional quick-drying fabric clothing.

2. Wear a breathable sun hat.

3, carry people Dan, ten drops of water, Huoxiang Zhengqi water, essential balm, cool oil and other heatstroke prevention drugs.

4. Bring light salt water or a little salt.

3. Accidental drowning

Fire and water are always the most ruthless.

In outdoor activities, whether climbing, drifting, downhill, orienteering, etc. You will often meet rivers, lakes and seas. Therefore, drowning is an accident with high frequency in outdoor sports.

Due to the increasing popularity of outdoor sports, the number of outdoor accidents and even casualties is gradually increasing, and the proportion of drowning accidents in rainy season is as high as 52%.

Tip:

1. When crossing in rainy days, avoid "spillway"; When camping in the rainy season, you should also avoid the "spillway".

2. When crossing the wooden bridge or the stone pier bridge, untie the backpack so that it can be discarded at any time.

3, through the rapids, rope should be used for protection.

4. Weak concept

The more you follow your heart, the easier it is to "lead a dog"

Many people temporarily changed the route up and down the mountain because of curiosity and adventure, and had to call the police after getting lost.
