What should you do if you are lost in the jungle? Or trapped in a deserted islands? Have you seen that movie Cast Away played by Tom Hanks? How to survive in such situation? It depend on our inner strength, our spirit to conquer the challenge. Not to to mention also the important of our knowledge on how to survive the situation, how to get food, call for help, get notice, not to get bitten by wild animal and live for another day.
So here are some basic knowledge for survival, always remember these:
A fire not only keeps you warm, it’s a morale booster and can be used as a smoke signal . In wet conditions, get dead branches off trees and shave them. It’s easy to kindle the fire this way. Always carry matches or s lighter in water proof bags. Dry bamboo, termite’s nests or cotton balls dipped in Vaseline make excellent tinder while twigs, small leaves and dry bark will keep the fire going.
Always bring your mobile phone — you never know where it will work. Don’t scream your lungs out — you’ll waste energy and your voice won’t travel far unless rescuers are within hearing distance. A whistle is a great piece of survival gear. If you need to start a signal fire, choose a clearing away from overhanging branches. Dig a trench or build an earth wall around the fire if it’s close to other trees or plants. Rubber tyres or green branches give a good, dense smoke. Spread out a reflective blanket (if you have one) to help searchers spot you from the air. Use a compact mirror, a knife blade, a thin foil or ready-made signal mirror with the sun to flash light signals.
The average person can survive for three weeks without food, but only three days without water. Common symptoms of dehydration are dizziness, lethargy and disorientation. If you’re lucky, you may be close to a stream or river. Otherwise, collect rainwater, dig in the dry streambeds or look for rainwater in bamboo, hollow stumps or pitcher plants. Vines are a good source of water, but vines with milky sap is poisonous. Use your bandanna to blot the dew from plants at dawn and wring it into your mouth. Or, tie a plastic bag around a leafy branch and evaporation from the leaves will produce condensation in the bag.
Though you can go without food for at least a week, hunger weakens the body and makes you more susceptible to hypothermia. Look out for wild fruits, roots, leaves, the soft heart of young stems or palm tree’s branches. Ferns and bamboo shoots are delicious. Though not appetizing, boiled lichens are safe to eat. A tip for testing plants: if a plant smells of almonds (hydrocyanic acid) or peaches (prussic acid) when crushed dump it. Rub a piece of crushed plant lightly on a soft skin area (inside of arm) and wait five minutes to check if any rash, swelling or burning appears. If these happen, they could be not safe to eat. Worms and insects are a good source of protein if you can get over the squeamish factor.
A shelter will keep away the rain and wind, and keep you warm. Look for a camp site that’s sheltered from the wind, a higher ground with less risk of flooding, safe from rock falls and away from animals’ watering holes. Most "lost" cases happen to day hikers, thus you’re likely not to carry a tent. You can make a simple A-frame shelter with a plastic sheet or your poncho and tree branches. Or gather some branches, make a frame and use leaves to cover up. Bamboo makes great shelters but be careful of sharp slivers or splinters when it is cut.
Hope that help us. Who knows when is something bad is going to happen, right? Bye... :)
