Hot weather can be dangerous — but recognizing the warning signs early can save a life. This post breaks down the difference between heat exhaustion and heat stroke, and what to do about each.
Heat Exhaustion
Heat exhaustion is the body's response to losing too much water and salt through heavy sweating. Warning signs include:
- Dizziness or weakness
- Muscle cramps
- Nausea
- Cool, clammy skin
- A fast, weak pulse
What to do: Move to a cool place, rest, sip water, and cool the body with damp cloths or a fan. If symptoms get worse or last more than an hour, seek medical care.
Heat Stroke — A Medical Emergency
Heat stroke is far more serious and requires immediate emergency care. Call 911 if you see:
- Loss of consciousness
- Hot, dry skin (sweating may have stopped)
- A body temperature of 104°F (40°C) or higher
- A fast, strong pulse
While waiting for help, move the person to a cooler place and work to lower their body temperature.
Staying Safe in the Heat
- Avoid prolonged sun exposure, especially midday
- Check on children, older adults, and anyone working outdoors — they're most at risk
Awareness saves lives. When in doubt, treat it as an emergency and call for help.
