Take Precautions for Extreme Heat

The National Weather Service in St. Louis is predicting a stretch of extreme heat for the St. Louis metropolitan area. The combination of hot temperatures and high humidity will likely lead to an increased risk of heat related stress and illness. The very young, elderly, those without air conditioning, and those participating in strenuous outdoor activities will be the most susceptible.

The City of St. Louis Department of Health is warning residents to take extra precautions if they will be working or spending time outside. When possible reschedule strenuous activities to the early morning or evening.

Also, during times of extreme heat, residents are encouraged to check on seniors, homebound, and neighbors with medically needy neighbors.

Know the signs and symptoms of heat exhaustion and heat stroke.

Heat Exhaustion

Heat exhaustion is the most common heat-related illness
  • Heat exhaustion results in elevated body temperature and dehydration
  • Symptoms include heavy sweating, paleness, muscle cramps, tiredness, weakness, dizziness or fainting, headache, nausea or vomiting
  • If symptomatic, rest, loosen clothing, take a cool shower, drink cool water and seek medical attention if symptoms worsen or last longer than one hour

Heat Strokes

Heat stroke occurs when the body's core temperature reaches 104°F
  • Heat stroke can be deadly
  • Symptoms include a high body temperature, red skin, hot or dry skin, rapid pulse, throbbing headache, dizziness, nausea, confusion, unconsciousness
  • If symptomatic, call 9-1-1 immediately, move to a cool, shady spot.Cool your body rapidly with cool water and monitor your body temperature. Avoid alcoholic drinks

Best Protection

The best protection against high heat is staying in an air-conditioned building.
  • Thermostats should be set to no warmer than 78°F, particularly when children or elderly are in the building
  • Do not rely on fans as your primary cooling source

At high temperatures air from fan actually increases the body's heat stress by delivering heated air to the body faster than the body can get rid of the heat.


Protect your children from heat-related illness and injury:
  • Never leave a child unattended in a vehicle
  • Reduce a child's outdoor activity during hot, humid weather and the hottest part of the day
  • Give children plenty of cool water to drink
