To avoid becoming the lead story on the evening news, be prepared. Before you head out on a hike, check the weather, take plenty of water, and make sure someone knows where you’ll be and when you’ll be back. Bring clothes to keep you warm when wet. Avoid cotton, which is easy to take in moisture(潮气).
“To avoid getting lost, check often to make sure you’re still on the trail(路线),” says John Dill, a search-and-rescue worker at Yosemite National Park in California. “The minute you think you might not be on the trail, stop.” If you’re not alone, focusing on the needs of others can help you get rid of your own fears. Other keys to survival: staying observant and remembering to rest.
The surest way to get out alive is to take basic preventive measures, such as taking a set of survival equipment. It includes waterproof matches for starting a fire, a folding knife for cutting branches, and a plastic cloth for making shelter.
Generally, people who try to find their own way out get along worse than those who stay, says Richard N. Bradley, MD, of the American Red Cross. Find shelter before dark, and try to keep dry. Stay visible so that anyone searching can see you. In a wide-open area, make a signal with colorful tools, make a big X out of rocks, or dig a long shallow hole.
You can go several days without eating, so in most cases, you’d better not search for food, since there are lots of poisonous plants in the wild, says Dr Bradley. You cannot survive without water, so if you run out of water, it’s usually better to drink from a stream with suspect water than to go without.
