Outdoor sports need to pay attention to the following nine issues

I. Directional issues

Before the trip, collect as much as possible maps and related information about the activity area, and make a preliminary understanding of the larger turns and obvious landmarks that will appear. When there is a contour map, the intended route and direction can be analyzed, such as: the need to cross several mountain beams, through several passes, the general elevation rise and fall, which will help determine the direction in the march.

Second, the waterproof problem

In the rainy season or rainy areas, especially the long crossing, such as waterproofing is not adequately prepared for the entire activity will encounter great trouble. Such as: no dry clothing can be changed, cameras, batteries, food and other items were wet damage. Therefore, before the trip to do some understanding of the climate of the activity area, and be prepared accordingly.

Third, the problem of drinking water

In short-distance crossing, such as known hydration difficulties should bring enough drinking water, about 2 liters per person per day (if you do not need to do FB meals). For long-distance crossing, water can be taken from streams and waterfalls, rivers, lakes and ponds on the way, but be sure to observe the pollution situation, such as: whether there are livestock activities, animal carcasses, feces and other pollutants near the water. When there is a lot of sediment in the water, make the water settle for more than 10 minutes. In areas where there are many locusts, use open or transparent containers to find out whether there are locusts in the water in time.

IV. Fire problem

When you travel, you should carry more than one fire source, such as: lighter (various types), matches, fire sickle, etc. It is best to bring camping stoves, gas cans or fuel cans when you have the conditions. When making a fire in the campground, pay attention to whether the campground is a no-fire zone, and don't violate the rules except for survival needs. Before making a fire, prepare some dry, thin firewood (slightly thinner than chopsticks), put it on the bottom of the stove piled up with rocks, then set up thick firewood on top, light the thin wood and blow hard with your mouth, then you can blow the fire. When it rains or the firewood is wet, you can split the thick wood and take the dry wood from the middle, then chop it fine and use it as firewood (you need a machete or other tools at this time). V. Camping problems

Find a safe, sheltered, dry and flat high place to camp. Pay attention to the surrounding environment, such as whether there are falling rocks and rolling stones, how the wind is blowing, and whether there are animal nests and beehives. Try not to camp along the river unless you are sure it is a dry period and the water level will not change. Don't camp close to the water, there are more mosquitoes and insects.

VI. Wildlife

Prepare medicines such as cool oil, wind oil and safflower oil when you travel. Playing leg bindings can effectively prevent locusts, snakes and other creatures from attacking the legs. You can prepare snake medicine in places where there are a lot of poisonous snakes.

Seven, nutritional supplements

In the longer wilderness crossing, physical exertion, sweating, the human body is prone to salt deficiency, electrolyte imbalance, nutritional deficiencies and other phenomena, which can seriously affect physical strength and health, and sometimes even very dangerous, so timely replenishment.

Eight, warmth problem

In many areas (such as: desert, mountainous areas), the temperature difference between day and night is large, some crossing altitude, rising large, the temperature will drop as the altitude rises. Pay attention to keep warm is necessary, especially after a lot of sweating and before going to bed.

IX. Other related issues

Climbing and descending unless it is a last resort, rather go around and walk more than try dangerous climbing and descending, especially when crossing alone and carrying weight. If you must climb and descend, you should first remove your backpack, climb and descend empty, and then use auxiliary ropes or straps to lift the equipment.

When passing through dangerous areas (such as one-way bridges, wading, cliff edges, etc.) you should remember to loosen the chest strap and waist belt of your backpack to ensure that you can unload it in time and quickly and lose the pawn to save the car. Night road except for special areas (such as desert) do not easily risk taking the night road, many lost are occurred in the case of low visibility, and night road is easy to cause loss of footing. When you have to walk at night, have a headlamp ready is the best, flashlight will take up a hand, not conducive to balance protection.

Wading in the unknown water depth and underwater conditions do not venture to wade through, should try to find out ideas. If you have beach shoes, try not to wade barefoot, because it is easy to slip and stab, but also be careful of the rocks in the water, they are often very round and slippery, and you will lose your footing if you are not careful. In addition, the speed of water flow should be well estimated before wading. Take away all visible trash left behind. At least the non-biodegradable garbage should be taken along on long crossings until there is a uniform garbage dump. So garbage bags are a must.
