Overheated?

If someone is suffering from a heat related illness there are some things you can do until medial help arrives.
1) Move them to a cool environment.  At the very least move them into the shade.
2) Have them lay down and elevate their feet.
3) Sponge them with cool water.  If ice is available place it on the groin, underarms or neck.
4) If available and possible let them SIP water, preferably warm NOT cold water.

Supersonic Safety Research reminds you that heat related illness is VERY serious, take precautions and know what to do until help arrives.  Remember, more people die from the heat than from the cold.
