he Oklahoma State Department of Health  reminds residents that heat-related illness can range from heat cramps and heat exhaustion to hyperthermia (overheating) and heat stroke. Heat stroke occurs when the body is unable to cool itself sufficiently, and it often results in severe organ damage or even death. 


It is important to recognize the signs of heat exhaustion and heat stroke and act quickly.


Heat Exhaustion


Heavy sweating


Cold, pale, clammy skin

Fast, weak pulse

Nausea or vomiting



Heat Stroke

Body temperature greater than 103 degrees

Hot, red, dry or moist skin

Rapid and strong pulse


A heat stroke is a medical emergency. If any signs are recognizable, call 911 immediately and move the person to a cooler environment. Reduce the person’s body temperature with cool cloths or even a bath.
