When temperatures climb into the triple digits, the danger isn’t always obvious. Heat doesn’t announce itself the way a storm or a fire does — it just builds, quietly straining your body and your home until something gives out. The good news is that a little preparation goes a long way. Here’s how to protect the people you love and the property you’ve worked hard for when a heatwave hits.
Know the Warning Signs
Heat-related illness moves along a spectrum, and catching it early makes all the difference.
Heat exhaustion shows up as heavy sweating, cold or clammy skin, dizziness, nausea, and a fast but weak pulse. If someone shows these symptoms, move them to a cool space, loosen their clothing, and offer sips of water.
Heat stroke is a medical emergency. Watch for a body temperature above 103°F, hot and dry (or damp) skin, confusion, a rapid and strong pulse, and possible loss of consciousness. Call 911 immediately and try to cool the person down while you wait — cold cloths, a cool bath, or moving them to air conditioning if available.
Children, older adults, pets, and people with chronic health conditions are especially vulnerable, so check in on family members and neighbors who may need extra support.
Protecting Your Family
Stay hydrated before you feel thirsty. By the time thirst kicks in, you’re already behind. Water is best; skip sugary or alcoholic drinks, which can speed up dehydration.
Time outdoor activities wisely. If you or your kids are heading outside, aim for early morning or evening hours when temperatures are lower, and take frequent breaks in the shade.
Dress for the heat. Lightweight, loose-fitting, light-colored clothing helps your body regulate temperature more effectively than dark or tight fabrics.
Never leave anyone in a parked car. Not even for a minute. Interior temperatures can climb more than 20 degrees within the first ten minutes, which is especially dangerous for children and pets.
Check on vulnerable neighbors and relatives. A quick phone call or knock on the door can catch a problem before it becomes an emergency.
Protecting Your Home
Heatwaves don’t just threaten people — they put real stress on your house, too.
Keep your cooling system in shape. Have your HVAC system serviced before peak season, change air filters regularly, and consider a programmable thermostat to manage energy use efficiently.
Seal the gaps. Weatherstripping around doors and windows keeps cool air in and hot air out, easing the load on your air conditioner.
Use fans strategically. Ceiling fans and portable fans help circulate cool air and can let you raise the thermostat a few degrees without sacrificing comfort.
Block direct sunlight. Blackout curtains, blinds, or reflective window film can significantly cut down on heat gain, especially on south- and west-facing windows.
Watch for fire risk. Extreme heat and dry conditions raise wildfire risk in many areas. Keep gutters clear of debris, maintain defensible space around your property, and know your evacuation routes if you live in a high-risk zone.
Protect your appliances and electronics. Power grids can strain under heavy air conditioning demand, leading to brownouts or surges. Consider surge protectors for sensitive electronics.
Build a Heatwave Emergency Kit
A little preparation now saves stress later. Consider keeping these on hand:
- Extra water (at least one gallon per person, per day)
- Battery-powered or hand-crank fans
- A battery-powered radio for emergency updates
- A list of cooling centers in your area
- Extra medication and a basic first-aid kit
- Pet supplies, including extra water and shade access
Know Where to Cool Off
Many cities open public cooling centers — libraries, community centers, or malls — during extreme heat events. If your home loses power or your AC fails, having a backup location ready can be a lifesaver, literally.
Don’t Forget Your Home’s Bigger Picture
Extreme heat can also contribute to less obvious risks: foundation shifting from dry soil, roof damage from prolonged sun exposure, and increased strain on plumbing and electrical systems. Periodic home maintenance checks — especially before and after heatwave season — can help you catch small issues before they turn into costly repairs.
Stay cool, stay hydrated, and look out for one another. A few small precautions can make all the difference when the temperature rises.
