Heat Stroke vs. Heat Exhaustion: Key Symptoms, Treatment & Prevention
Heat exhaustion is the body’s early overheating warning: heavy sweating, dizziness, and a fast pulse. Heat stroke is the next, lethal stage where the core temp tops 104 °F and sweating stops. Both are heat illnesses, but only one is an emergency.
People confuse them because both strike after sun exposure and feel awful. Yet one needs shade and Gatorade, the other an ambulance. Mixing them up costs lives.
Key Differences
Heat exhaustion: sweat pours, skin cool/clammy, temp <104 °F, rapid pulse. Heat stroke: no sweat, skin hot/dry or damp, temp ≥104 °F, confusion, seizures, possible coma.
Which One Should You Choose?
Choose prevention: hydrate, schedule shade breaks, wear light clothing. If signs appear, move to AC, sip electrolytes. If mental state shifts or temp spikes, call 911 immediately—every minute counts.
Examples and Daily Life
After a noon 5K, a runner feels woozy and drenched—classic heat exhaustion. The same athlete, ignoring it and running another mile, could collapse, stop sweating, and seize—heat stroke in action.
Can kids get heat stroke faster than adults?
Yes, children’s thermostats are immature; they heat up three to five times quicker, so never leave them in parked cars.
Is sports drink enough to treat heat stroke?
No, sports drinks help heat exhaustion, but heat stroke needs ice baths and emergency care—call 911 first.
