What’s the Difference Between Heat Stroke and Heat Exhaustion?

Heat exhaustion and heat stroke are heat-related conditions caused by prolonged exposure to high temperatures. Heat exhaustion is less severe but can progress to heat stroke, a medical emergency requiring immediate attention.

Symptoms of heat exhaustion

• Heavy sweating and clammy skin
• Weakness, dizziness, or fainting
• Nausea or vomiting
• Headache
• Rapid, weak pulse

Symptoms of heat stroke (requires emergency care)

• High body temperature (103°F or higher)
• Hot, dry, or damp skin (lack of sweating)
• Confusion, slurred speech, or unconsciousness
• Rapid, strong pulse
• Seizures

What to do in each case

• For heat exhaustion: Move to a cool area, drink fluids, and rest. Seek medical attention if symptoms don’t improve.
• For heat stroke: Call 911 immediately. Cool the person down with ice packs, shade, or a cool bath while waiting for emergency care.
