First Aid Overview

First Aid for Heat Emergencies

There are two main types of heat emergencies that require first aid:

Heat Exhaustion: Heat exhaustion can result from exposure to hot, humid environments. Symptoms include moist, pale, clammy skin; heavy sweating; normal or below-normal body temperature; weakness; dizziness; headache; nausea; vomiting; muscle cramps; fainting. Left untreated, it may progress to heatstroke.

Heatstroke: Heatstroke is a life-threatening emergency marked by an extremely high body temperature that results from overexposure to heat. Symptoms include a high body temperature, possibly above 106 degrees Fahrenheit; red, hot, dry skin; lack of sweating; constricted pupils; rapid pulse (more than 100 beats per minute); confusion or unconsciousness. WITHOUT IMMEDIATE MEDICAL ATTENTION, VICTIM MAY DIE.
