As heat waves become more frequent, understanding heat-related illness is critical for safety. Both conditions stem from the body's failure to cool itself in high heat or humidity.
Heat Exhaustion is a serious but less severe condition. Key symptoms include dizziness, nausea, heavy sweating, cold/pale skin, and a fast, weak pulse. If these occur, move to shade or air conditioning, loosen clothing, and drink cool fluids. Seek medical help if symptoms persist for over an hour.
Heat Stroke is a life-threatening emergency. It occurs when core temperature exceeds 104°F, affecting brain function. Symptoms can include confusion, passing out, seizures, and red skin. The person may not recognize their own danger.
If heat stroke is suspected, call 911 immediately. While waiting for help, cool the person aggressively. The ideal method is immersion in a tub of cold, icy water. Alternatives include a cold shower, hosing down, or applying ice-cold, wet towels, changing them every few minutes.
