Recognizing heat-related illness early can prevent serious complications.
Heat exhaustion and heat stroke are serious conditions that occur when the body becomes unable to regulate its temperature.
Early warning signs of heat exhaustion may include:
• Heavy sweating
• Weakness or fatigue
• Dizziness or headache
• Nausea
• Muscle cramps
If symptoms worsen, the condition may progress to heat stroke, which can be life-threatening.
Signs of heat stroke may include:
• Confusion or disorientation
• Rapid pulse
• Fainting or collapse
• Very high body temperature
Moving to a cooler area, resting, and drinking water may help during early symptoms. However, severe symptoms require immediate medical attention.
Emergency Action
If someone experiences confusion, fainting, or severe heat illness symptoms, call 911 immediately.
