What is Heat Exhaustion?

Heat exhaustion is a heat-related illness that occurs when you are exposed to high temperatures and you sweat excessively. This causes dehydration due to loss of water and salt.

Signs and symptoms of heat exhaustion include profuse sweating, dizziness, weakness, headache, nausea, vomiting, muscle cramps, or dark-colored urine (a sign of dehydration).

If symptoms are severe you may experience pale, cold, or clammy skin, rapid heart rate, or faintness. If this occurs, or if you have existing heart problems or high blood pressure, seek medical attention immediately.

Learn to prevent heat exhaustion and stay safe and cool in the heat.
