The National Weather Service in St. Louis has issued a Heat Advisory for the City of St. Louis area. The advisory is in effect from 1:00pm, Monday, July 10, 2017 through 9:00pm, Wednesday, July 12, 2017. Temperatures are expected to rise quickly into the 90s by midday to dangerous levels of heat during the afternoon and evening. Heat index values are expected to be up to 104 degrees.

The combination of hot temperatures and high humidity will likely lead to an increased risk of heat-related stress and illness for people and pets, especially for those living in un-air conditioned homes or apartments.

Heat Related Health and Safety Tips for People:

  • Avoid poorly ventilated areas and prolonged work in the sun.
  • Keep plenty of fluids on hand and try to stay in, or take frequent breaks in an air conditioned environment.
  • Know the signs and symptoms of heat exhaustion and heat stroke.
  • Wear light weight loose fitting clothing.
  • Never leave children unattended in a vehicle. Check the backseat. During extreme heat vehicle temperatures can reach lethal levels in a matter of minutes.
  • Continuously check on family members, neighbors, elderly, chronically ill, and friends. If they have air conditioning available, encourage them to use it. 
  • Replace Salt and Minerals: Heavy sweating removes salt and minerals from the body that need to be replaced. A sports drink can replace the salt and minerals you lose in sweat.
  • If you are on a low-salt diet, have diabetes, high blood pressure, or other chronic conditions, talk with your doctor before drinking a sports beverage or taking salt tablets.

Heat Related Health and Safety Tips for Pets:

  • In extreme heat, it is important that pets are in an air conditioned environment.
  • Never leave pets alone in a vehicle. If you see a pet in an unattended vehicle, call 911.
  • Watch for coolant leaking from your vehicle. A pet drinking just a small amount can cause death.
  • Do not force your animal to exercise after a meal in hot, humid weather. Limit exercise to the early morning or evening hours.
  • Never leave your pet standing on asphalt surfaces, as they can burn their paws.
