Be aware of heat stroke symptoms - Texas A&M AgriLife

AgriLife Extension specialist Debra Kellstedt, DrPH, said the body naturally heats up during physical activity but normally keeps itself cool by sweating.

“However, in cases of extreme heat and high humidity, the body heats up faster than it can sufficiently sweat in order to maintain a temperature in the normal range,” she said.

Heat exhaustion is the result of an excessive loss of water and/or salt, usually as a result of excessive sweating, Kellstedt

said.

Some heat exhaustion symptoms can include: Tiredness or weakness.

Agitation.

Headache. Dizziness. Cold, pale, and clammy skin.

Tingling skin. Fast, weak pulse. Fast, shallow breathing.

Heavy sweating.

Nausea. Muscle cramps. “In more serious instances, heat exhaustion can also cause vomiting or fainting,” she said.

To address heat exhaustion, Lopez said it is best to sip cool water, relocate to a cooler area, loosen your clothing, and put a wet cloth or cool compress on key areas of the body, such as the forehead, neck, and armpits.

“If there is vomiting, extreme weakness or the symptoms get worse and last more than an hour, you should seek medical help,” he said.
