Heat stroke and heat exhaustion: Differences, signs, and treatments
Healthline says heat exhaustion can progress to heat stroke if cooling is delayed, and symptoms may require emergency care within 30 minutes.
Healthline states, "Both heat stroke and heat exhaustion are caused by your body's inability" to cool itself. Heat exhaustion involves water and salt loss, while heat stroke is a severe medical emergency requiring immediate intervention.
Extreme heat or strenuous activity overwhelms the body's natural cooling mechanisms. Dehydration, tight clothing, age, and prescription medications all increase heat sensitivity and risk.
A temperature above 100 degrees Fahrenheit indicates heat exhaustion, while a reading above 104 degrees Fahrenheit signals heat stroke. Heat exhaustion typically resolves if you cool down within 30 minutes.
Call 911 immediately for heat stroke symptoms such as loss of consciousness or a rapid pulse. For heat exhaustion, treat with cool showers and hydration, seeking medical help if symptoms worsen.
Stay hydrated and wear loose, lightweight clothing during outdoor activities. Avoid leaving children or pets in parked vehicles, as temperatures can rapidly reach dangerous levels and increase serious complications.
