  • Avoid strenuous activity.
  • Active children, adults, and people with lung disease, such as asthma, should reduce prolonged or heavy exertion outdoors.

    • Call 911 immediately if you or someone you know has:
    • Hot dry skin.
    • Trouble breathing.
    • Rapid heartbeat.

  • Keep your pets safe:
  • Avoid dehydration: Pets can dehydrate quickly, so give them plenty of fresh, clean water. Walk your dog in the morning and evening: When the temperature is very high, do not let your dog linger on hot asphalt. Your pet's body can heat up quickly, and sensitive paw pads can burn.
  • Know when your pet is in danger: Symptoms of overheating in pets include excessive panting or difficulty breathing, increased heart and respiratory rate, drooling, mild weakness, unresponsiveness, or even collapse.
