Distinguishing Heat Exhaustion from Heatstroke: Recognizing Signs and Providing Aid

Why it matters locally: With California's frequent heatwaves, particularly in regions like the Central Valley and Southern California deserts, understanding the differences between heat exhaustion and heatstroke is crucial for public safety and emergency preparedness across the state.

When temperatures rise, individuals face risks from heat-related illnesses, including heat exhaustion and heatstroke. Recognizing the distinct symptoms of each condition allows immediate and effective response. Heat exhaustion develops gradually. Its symptoms include heavy sweating, cold skin, weakness, cramps, dizziness, headache, nausea, and disorientation. Individuals experiencing these signs need to move to a cooler area, loosen clothing, and drink water. They should also apply cool, wet cloths or take a cool bath. If symptoms worsen, last longer than one hour, or if the person begins vomiting, they require medical attention. Heatstroke represents a medical emergency. This condition progresses rapidly and can cause organ damage or death without immediate intervention. Key indicators of heatstroke include a body temperature of 103 degrees Fahrenheit or higher, warm or hot skin, confusion, slurred speech, seizures, and loss of consciousness. Victims of heatstroke also often experience a rapid pulse. Sweating may or may not be present. Anyone suspecting heatstroke in another person should immediately call 911. While waiting for emergency services, bystanders can help by moving the individual to a cooler location. They should also apply cool cloths or ice to the head, neck, armpits, and groin. A fan can also help cool the person. Individuals should avoid giving fluids to someone experiencing heatstroke. Early identification and proper care are critical in managing heat-related conditions.
