Distinguishing Heat Exhaustion from Heatstroke: Recognizing Signs and Providing Aid

Why it matters locally: With Maine's summer temperatures capable of reaching highs that pose a risk for heat-related illnesses, understanding the signs of heat exhaustion and heatstroke is critical for public safety. Emergency services across the state, such as Cumberland County Regional Communications Center (emergency dispatch) and Cape Elizabeth Fire-Rescue, may see increased calls related to these conditions.

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.
