Meta Description: Ohio faces a dangerous heat wave with a heat index of over 100°F. Learn how to stay safe, avoid power outages, protect your health and pets, and prepare for emergencies.
A scorching heat wave has settled over Ohio, with temperatures soaring and heat index values reaching dangerous levels. According to the National Weather Service (NWS), most of Ohio will be under a heat advisory on Thursday, July 24, with heat index values climbing up to 104°F.
This extreme heat not only puts your health at risk but can also lead to power outages, vehicle breakdowns, and increased danger for high-risk populations.
The heat index combines air temperature and humidity to measure how hot it feels to the human body. High humidity slows down the evaporation of sweat, making it harder for the body to cool off. That’s why 93°F can feel like 106°F when humidity is high.
Akron & Canton
July 24: 93°F (feels like 101°F)
July 25: 88°F with potential storms
Cincinnati
July 24: 95°F (feels like 106°F)
July 25: 94°F, chance of rain
Columbus
July 24: 94°F (heat index 100°F)
July 25: 92°F with storm chances
The Ohio Department of Health (ODH) identifies several high-risk groups:
Infants and young children
Older adults
People with chronic health conditions
Pregnant individuals
Outdoor workers and athletes
Residents without air conditioning
Follow these essential tips from ODH, CDC, and Ready.gov:
Sip water regularly; don’t wait to feel thirsty.
Drink 2–4 cups of water per hour if active outside.
Avoid alcohol and caffeine — they dehydrate the body.
Stay indoors during peak heat (10 AM – 4 PM).
Wear loose, light-colored clothing and wide hats.
Apply sunscreen (SPF 30+), take frequent shade breaks.
Heatstroke: 103°F body temp, confusion, no sweating — call 911 immediately
Heat Exhaustion: Dizziness, nausea, cold clammy skin — cool down and hydrate
Visit or call older neighbors and those with health issues.
Make sure they have access to cool air or a cooling shelter.
Keep pets indoors or provide shade and fresh water outside.
NEVER leave pets in a vehicle — it can be fatal within minutes.
With high energy demand, power outages are possible. Here’s how to prepare:
Close curtains and blinds.
Use aluminum foil-covered cardboard as window reflectors.
Move to lower floors if no AC (heat rises).
If under 95°F, open windows and use fans.
Above 95°F, close windows to keep hot air out.
Drink ¾ gallon of water daily.
Add electrolytes or salty snacks if you sweat heavily.
2-week supply of food, water, and medicines.
Include phone chargers, batteries, and first-aid items.
Have a 3-day “go bag” ready in case of evacuation.
Heat can damage medications or increase your sun sensitivity:
Insulin
Inhalers
Epinephrine
Thyroid medications
Antibiotics
Acne treatments
Blood pressure pills
Oral contraceptives
NSAIDs (pain relievers)
If you don’t have AC at home, head to:
Public libraries
Malls
Designated cooling centers
Community centers
Call local authorities or check your city’s official website for shelter availability.
Midwestern humidity can be intensified by a phenomenon called "corn sweat." Corn releases water vapor through its leaves, raising local humidity and making it feel even hotter.
This Summer 2025 heat wave is no joke. Stay informed, stay cool, and help your neighbors and pets survive these dangerously high temperatures. Bookmark this post, share it with friends, and stay updated via trusted sources like NWS, ODH, and CDC.
