Heat Wave Safety: How to Stay Cool and Healthy This Summer

Understanding Heat Waves in 2026

The summer of 2026 has brought some of the hottest temperatures on record to the United States. With climate change driving more frequent and intense heat events, Americans are facing longer and more dangerous heat waves than ever before. The National Weather Service has issued excessive heat warnings for more than 30 states this week.

Heat waves are the deadliest weather-related phenomenon in the US, causing more deaths than hurricanes, tornadoes, and floods combined. Knowing how to protect yourself is not just important, it can be life-saving.

What Is a Heat Wave?

A heat wave is defined as a period of abnormally hot weather lasting two or more days. The specific temperature threshold varies by region, but generally, a heat wave occurs when temperatures are at least 10 degrees Fahrenheit above the normal high for that area.

In 2026, heat waves have been particularly severe due to:

• Climate change pushing average temperatures higher
• Urban heat islands making cities even hotter
• Extended duration with heat events lasting weeks instead of days
• Overnight temperatures staying elevated, preventing recovery

Who Is Most at Risk?

Certain populations are more vulnerable to extreme heat:

High-Risk Groups:

• Adults over 65
• Children under 5
• People with chronic medical conditions
• Outdoor workers
• People experiencing homelessness
• Those without access to air conditioning

Medical Conditions That Increase Risk:

• Heart disease and high blood pressure
• Diabetes
• Obesity
• Mental health conditions
• Respiratory diseases

Heat-Related Illnesses

Recognize the warning signs of heat-related illness:

Heat Exhaustion:

• Heavy sweating
• Cold, pale, clammy skin
• Fast, weak pulse
• Nausea or vomiting
• Muscle cramps
• Tiredness, weakness, dizziness

Heat Stroke (Medical Emergency):

• High body temperature (103°F or higher)
• Hot, red, dry, or damp skin
• Fast, strong pulse
• Confusion or loss of consciousness
• No sweating despite the heat

If you suspect heat stroke, call 911 immediately. This is a life-threatening emergency.

How to Stay Cool

At Home:

• Stay in air-conditioned spaces as much as possible
• If you don't have AC, spend time in public places like malls, libraries, or cooling centers
• Take cool showers or baths
• Use fans strategically, but remember fans don't cool the air, they just move it
• Close blinds and curtains during the hottest parts of the day
• Avoid using the oven or stove, which heats up your home

Outdoors:

• Schedule outdoor activities for early morning or evening
• Wear lightweight, loose-fitting, light-colored clothing
• Apply sunscreen with SPF 30 or higher
• Take frequent breaks in the shade
• Drink water every 15-20 minutes, even if you don't feel thirsty
• Never leave children or pets in parked cars

For Your Body:

• Drink plenty of water throughout the day
• Avoid alcohol and caffeine, which dehydrate you
• Eat small, frequent meals instead of heavy ones
• Apply cold compresses to your wrists and neck
• Wear a hat and sunglasses when outdoors

Cooling Centers and Resources

Most cities and counties operate cooling centers during heat waves. These are air-conditioned public spaces where anyone can go to cool down. To find a cooling center near you:

• Call your local 211 hotline
• Check your city or county government website
• Contact your local Red Cross chapter
• Ask at your local library or community center

Many communities also distribute free water and provide transportation to cooling centers for those who need it.

Protecting Vulnerable Family Members

Check on elderly neighbors, friends, and family members regularly during heat waves. Make sure they:

• Have access to air conditioning
• Are staying hydrated
• Are taking their medications properly
• Know the signs of heat-related illness

For children, ensure they are dressed appropriately, stay hydrated during outdoor play, and never leave them in a parked vehicle.

Pet Safety in Extreme Heat

Pets are also vulnerable to heat-related illness:

• Provide shade and fresh water at all times
• Avoid walking dogs during the hottest parts of the day
• Check pavement temperature before walks (if it's too hot for your hand, it's too hot for paws)
• Never leave pets in parked cars
• Watch for signs of heat stress: excessive panting, drooling, or lethargy

Emergency Kit Essentials

Prepare an emergency kit for extreme heat events:

• Bottled water (one gallon per person per day)
• Battery-powered or hand-crank fan
• Cool packs or ice
• Battery-powered radio
• Flashlight and extra batteries
• First aid kit
• Any necessary medications
• Phone charger
