7. Lack of Sweating

Sweating is the body's main cooling mechanism, so when someone in the heat suddenly stops sweating, it's a warning sign. It can mean heat exhaustion has tipped into heat stroke, with the body losing its ability to cool itself. Skin that is hot and dry to the touch is a classic indicator. Start active cooling right away: get the person into shade or air conditioning, wet the skin with cool water, and apply cold packs to the neck, armpits, and groin. One thing to know: not everyone with heat stroke stops sweating. People who overheat during heavy exertion may sweat heavily instead, so don't rule out heat stroke just because someone is still sweating.
