Extreme Heat: Keep Cool, Stay Safe

As millions across the globe are under heat advisories, temperatures are warming up in Central Ohio. Temperatures in the Columbus area are expected to warm over Labor Day weekend and push into the 90s through Wednesday, September 6th. High heat combined with multiple days of high humidity present potential health concerns for Central Ohio residents.

Heat Index

High temperatures receive a lot of focus when, really, the heat index should be the focus. The heat index or ‘real feel’ is a tool used to indicate how intense the heat is and the risks it poses to people. The higher the index, the more dangerous prolonged exposure is to human health. Several variables in the air affect how the temperature feels, and it can be tricky to communicate. 


High humidity makes the air feel hotter and more uncomfortable. It also affects the body’s ability to regulate internal temperature. The body sweats to cool itself, and when there is a high amount of moisture in the air, it’s harder for the sweat on your skin to evaporate. When humidity reaches a certain level, even moderate temperatures can become harmful.

Who is At Risk?


Groups most at risk of heat illness include children, older adults, people experiencing homelessness, people with pre-existing conditions, people with disabilities, indoor and outdoor workers, emergency responders, incarcerated people, low-income communities, pregnant people, athletes, and more. Pets and service and support animal owners should take special precautions to protect the health of their animals during extreme heat conditions.

As direct service providers, your staff are an invaluable resource in preventing heat-related illness and death in the Columbus community. Train staff to Avoid. Spot. Treat. and make tools available to be shared with clients and the community.

Health Effects

In hot temperatures, your body may be unable to cool itself properly, leading to serious health problems. Heat exhaustion can occur after you’ve been exposed to high temperatures, and it is often accompanied by dehydration. Without proper intervention, heat exhaustion can progress to heat stroke, a health emergency.

Avoid. Spot. Treat.


  • Prepare for the heat: Tune in regularly to local weather forecasts and alerts. 
  • If going outdoors, wear loose-fitting clothing, avoid prolonged strenuous activities, take breaks often, bring shade, and hydrate properly.
  • Stay cool by spending time in air-conditioned spaces. If you do not have an air conditioner, use movie theaters, malls, libraries, and other cool public places, like rec centers.
  • Use fans to circulate air, and remember to hydrate frequently with fan use. 


  • Know who is at risk. Check on friends, neighbors, and older adults.
  • Cars can be deadly. Never leave children or animals unattended in vehicles.
  • Know the signs of heat exhaustion and stroke.


While waiting for medical attention, you can help someone with heat stroke or heat exhaustion.

  • Continue efforts to cool the person until help arrives or their body temperature falls below 102°F and stays there.
  • Do not give liquids.

Heat Exhaustion

  • Get medical attention if symptoms get worse or last longer than one hour.
  • Cool the body with:
    • Cool, nonalcoholic beverages;
    • Rest;
