There's something about the idea of being able to survive in the wilderness that's thrilling. We glorify it with TV shows like "Survivor" and "Man vs. Wild."
But survival in the harsh conditions of nature is no simple affair, and most lessons can't be learned from television. In fact, some of the "survival advice" that we've picked up over the years is totally wrong, often dangerously so.
Here are some myths you don't want to rely on if a short jaunt outdoors turns disastrous.
Myth: You can suck the venom out of a snakebite
Fact: If a bite delivers venom, it’ll immediately enter the bloodstream. Putting your mouth on the bite will deliver extra bacteria to the wound and may simply get venom into your mouth and esophagus. If someone gets bitten, try to keep heart rate low and hold the affected limb below heart level while getting to a hospital.
Myth: Always play dead when you are attacked by a bear
Fact: If you are out in the woods and you see a bear, the general advice is to quietly back away. If it's in your yard or around your campsite, make yourself large and loud, which should hopefully scare it off.
In most cases, a brown or grizzly bear attacks to defend itself or its cubs. At these times it will warn you off by making noise and pretending to charge. Back away from a defensive attack slowly. If the bear makes contact, play dead lying on your stomach with your hands over your neck. But in the rare case of a predatory attack, which comes with no warning (or if the bear seems to be stalking you), fight for your life.
Myth: You need to find a food supply immediately if you are lost in the wilderness
Fact: Not even close. You can survive up to six weeks without food. The exact amount of time might vary, depending on starting point and other health issues, but water and shelter from the elements are far more important.
Myth: The fluid in a cactus can save you from dying of thirst
Fact: If you’re experienced enough to pick out the one kind of barrel cactus that you can filter water from safely, this may work. But most of the time, cactus fluid will make you sick, causing you to vomit up precious liquid and leaving you more dehydrated.
Myth: Moss grows on the north side of a tree
Fact: Moss can grow on all sides of a tree, depending on environmental conditions. Don’t depend on this bit of folklore for navigation.
