The power of salt - One of the basic survival things to have around is probably already in your kitchen -salt. Salt has multiple uses ranging from allowing your body to retain water to prevent dehydration (as seen in sports drinks), to sanitation, to help in the healing of wounds and mild skin irritations. The power of salt rests in its ability to attract water molecules to itself. If you find yourself in a situation where you are at risk of being dehydrated, salt can definitely slow the process, thus helping your body hold onto water that's already there. Gatorade has about 110mg of sodium per 8oz. That would make it 0.22 teaspoons, but who cares about these exact laboratory numbers when in an emergency anyway. So to simplify, estimate a big pinch of salt for a 2 liter bottle (of Coke or whatever soda bottle you have lying around). Now, be careful not to put too much! Since salt attracts water, too much will suck the H2O right out of your cells. That is why drinking sea water will eventually kill you, when lost at sea. Now, for sanitation purposes, salt kills most bacteria the same way it does a slug. It is very effective for wounds. Putting salt can help minimize bacteria in and the surrounding tissue, as well as cauterize the injured area by drying it up.
