Arlington County has a number of tips for beating the heat, including:

  • Drink plenty of non-alcoholic fluids like water, even if you’re not thirsty.
  • Wear light-weight, loose-fitting clothing.
  • Stay cool by staying indoors during the hottest parts of the day.
  • Schedule outdoor activities carefully and wear sunscreen.
  • If you exercise outdoors, go in the morning or evening hours.
  • Eat light, regular meals — avoid hot foods and heavy meals.
  • Never leave anyone — infants, children, or pets — in a parked car.
  • Know the signs of heat-related illness — these include:
    • An extremely high body temperature (above 103°F)
    • Red, hot and dry skin (no sweating)
    • Rapid, strong pulse
    • Throbbing headache

The county also advises residents to conserve electricity to help prevent brownouts from excessive power usage during the extreme heat.
