Outdoor travel refers to a combination of tourism and recreational sports that emphasize experience and enjoyment, including self-guided tours, road trips, camping, hiking, flying, water activities, mountain climbing, rock climbing, exploration, skiing, rollerblading, BMX, and extreme sports. Participants in outdoor tourism often possess certain qualities, have a certain level of financial means, value environmental protection, and have a heart for public welfare, charity, and helping others.
Emergency first aid measures for outdoor travel
1. Venomous snake bites

If you are bitten by a venomous snake in the wild, the victim may experience symptoms such as bleeding, localized swelling and redness, and pain, and in severe cases can die within a few hours. Quickly tie a cloth strip, handkerchief, or tie tightly above the wound to prevent the spread of venom, then use a disinfected knife to make a cut about 1 cm long and 0.5 cm deep at the wound site, and suck out the venom with your mouth. If there is no damage to the oral mucosa, digestive fluids can neutralize the venom, so there’s no need to worry about poisoning. For insect stings or bites: apply a cold compress with cool water, remove the stinger, and then apply ammonia or milk.
2. Fractures or dislocations

Immobilize with a splint and then apply a cold compress. If you fall from a tree or rock and injure your spine, place the person on a flat and sturdy stretcher, keep their body stable, and avoid any movement before sending them to the hospital.
3. Food poisoning

Eating spoiled or rotten food can cause not only abdominal pain and diarrhea but also symptoms such as fever and weakness. Drink plenty of fluids or saline solution, or try inducing vomiting to expel the contaminated food.
4. Finding north and south when lost during outdoor trips

You can observe a tree stump—the wider rings indicate the southern side; look at a tree—the branches and leaves are denser on the southern side and sparser on the northern side; check ant nests, which mostly face south; in rocky areas, find a prominent rock—moss-covered sides indicate the north, while dry and bare sides indicate the south; or use a watch to determine direction: divide the current time by 2, then point the result toward the sun—the direction the 12 o’clock mark on the watch points to is north.
5. What to do if you encounter thunderstorms while traveling?

Do not take shelter under large rocks, cliffs, or cave entrances during a thunderstorm—electric arcs can pass through these areas and injure people seeking refuge. If the cave is deep, stay inside as much as possible. Do not ride a bike or horse during a thunderstorm, as they can attract lightning. Avoid hiding in isolated small sheds in open fields. Leave high ground and don’t take shelter under lone trees. Stay away from metal objects. A car is an ideal place to avoid lightning—even if struck, it rarely harms passengers. If swimming or on a small boat, get to shore immediately. Even on a large boat, take shelter under the deck.
