Survival myths that get people hurt
Myth
Drink your urine to survive.
Reality
Urine contains salts and waste that get more concentrated as you dehydrate. It worsens dehydration.
Myth
Suck out snake venom.
Reality
Suction and cutting don't remove venom and cause harm. Keep the person calm, immobilize the limb, and evacuate.
Myth
Homemade charcoal makes water drinkable.
Reality
Improvised charcoal can improve taste and clarity but doesn't reliably remove pathogens. Disinfect afterwards.
Myth
Moss only grows on the north side of trees.
Reality
Moss grows wherever it's damp and shaded. Use the sun, stars or a compass.
Myth
Rub frostbite with snow.
Reality
Rubbing damages tissue. Rewarm gently in warm (not hot) water only if refreezing won't happen.
Myth
Heat rocks in a fire and sleep on them.
Reality
River or wet rocks can crack or explode. Prefer insulation and proper sleeping systems.
Myth
Two magnets generate free electricity.
Reality
Electricity needs a changing magnetic field through a coil — that requires motion and energy input.
Myth
Running a generator in the garage is fine if the door is open.
Reality
Carbon monoxide still builds up to deadly levels. Generators belong outdoors, 20+ ft from the house.
Myth
The universal edibility test tells you what's safe to eat.
Reality
Many deadly plants cause delayed symptoms. Learn positive ID of a few local plants instead. Never wild mushrooms.
Myth
If animals eat it, it's safe for you.
Reality
Many animals tolerate plants that are toxic to humans. Use positive identification only.
