Heat Resistance

When your body is exposed to very hot conditions, it may lose its ability to regulate body temperature properly, resulting in heat-related illnesses. Anyone who works or plays in high heat is susceptible, but infants, young children, and people over 65 are most vulnerable.

When the heat is on, watch for these signs:

• Heat Cramps - symptoms: Muscle pains or spasms, usually in abdominal area or leg.
• Heat Exhaustion - symptoms: Cool, moist, pale skin; headache; dizziness; weakness; exhaustion; nausea.
• Heat Stroke - symptoms: Vomiting; loss of alertness or consciousness; high body temperature; rapid, weak pulse; shallow breathing; red, hot, dry skin; sweating has stopped.

What to do if you notice symptoms:
For heat cramps or heat exhaustion, seek shade, cool down promptly and take fluids. If symptoms continue beyond one hour, get medical care promptly.

For heat stroke, which is life-threatening, call 9-1-1 immediately; move out of the sun and cool down promptly - a cold, wet cloth may help. Don't take fluids.

On hot days at work or play, these steps can help prevent heat illness:

• Drink 2-4 glasses of water each hour; avoid alcohol and carbonated beverages.
• Take regular breaks to rest in the shade or air conditioning.
• Wear lightweight, light-colored, loose-fitting clothing.
• Wear a hat to keep a cool head.
• Avoid heavy meals, which may increase metabolic heat.
• Avoid strenuous tasks mid-day, the hottest time.
• Never leave young children or pets in a parked car.
• Keep a bowl of water in shaded areas for pets.
