Heat exhaustion may come on suddenly, or develop after a few days of being in the heat. It is a serious condition. These are the signs the staff of the Mayo Clinic wants you to watch for:
1. Cool, moist skin with goose bumps when in the heat.
2. Heavy sweating.
3. Feeling faint or experiencing dizziness.
5. Weak, rapid pulse.
6. Low blood pressure upon standing.
7. Muscle cramps.
If you experience any of these, act fast. If left untreated, heat exhaustion can easily lead to heat stroke. Drink cool, nonalcoholic beverages and rest. Take a cool shower, bath or sponge bath. Seek an air-conditioned place. Wear lightweight clothing. If symptoms get worse or last longer than an hour, get medical help.
