Heat Exhaustion / Heat Stroke

Heat Exhaustion

Heat exhaustion is a milder form of heat-related illness that can develop after several days of exposure to high temperatures and inadequate or unbalanced replacement​ of fluids.

Warning signs and symptoms of heat exhaustion include:

• heavy sweating
• paleness
• muscle cramps
• fatigue
• weakness
• dizziness
  
• headache
• nausea or vomiting
  
• cool, moist skin
  
• rapid but weak pulse
  
• rapid but shallow breathing
  

Heat stroke

Heat stroke is a more serious heat-related illness. It occurs when the body becomes unable to control its temperature. As a result, the body's temperature rises rapidly and it loses the ability to sweat, a function necessary for proper cooling. Unregulated body temperatures can rise dangerously to 106 degrees or higher within 10 to 15 minutes. If you suspect that someone is experiencing heat stroke, call 911. Emergency treatment is required to prevent death or permanent disability.

Warning signs and symptoms of heat stroke include:

• extremely high body temperature (above 103 degrees F)
• red, hot and dry skin (without sweating)
  
• rapid, strong pulse
• throbbing headache
• dizziness
• nausea​
