If you think you might be experiencing heat exhaustion, you should stop what you are doing and rest. Move indoors or to a shady area and drink cool water or a sports drink.
Seek medical attention for signs of heat exhaustion that do not improve within an hour of starting fluids and resting. Get immediate help if you, or someone else:
- Cannot keep fluids down
- Develop a fever of 103 degrees or higher
- Have trouble speaking, standing, or walking
- Are sweating excessively
- Become confused or lose consciousness
