Extreme Heat Safety and Preparedness

On average, extreme heat has killed more people in the last 10 years than any other weather phenomena. Remember these tips for staying safe in extreme heat:

Hydrate. Whether you feel thirsty or not, drink plenty of water to avoid becoming dehydrated, especially when you're working or exercising outside.
Educate yourself. Keep up with the latest temperature and heat index forecasts and current readings (take actions to stay cool and safe when the temperatures hits 85 degrees or the heat index hits 90 degrees). Know the warning signs of a heat illness, and how you can stay cool.
Act quickly when a heat illness is suspected. Seek medical attention immediately for any of these warning signs: cramping, rapid pulse, heavy sweating, hot red skin, dizziness, confusion, nausea, vomiting.
Take it easy. Anyone working or exercising outdoors should avoid overexertion, especially between the hours of 11 am and 6 pm. Take hourly breaks in the shade or in air conditioning.
