Heat Waves Are Getting Worse — Here’s How to Stay Safe This Summer

It’s not your imagination — summers are getting hotter, and heat waves are hitting harder and lasting longer across the country. From Phoenix to Philadelphia, millions of Americans are facing extreme heat warnings, and it’s only the beginning of the season.

While high temperatures may seem like just another summer annoyance, the risks are real — especially for children, older adults, and people with certain health conditions. The good news? With a few smart habits and some simple planning, you can stay safe and beat the heat.

Why Are Heat Waves Getting So Bad?

Heat waves are defined as prolonged periods of excessively hot weather — usually lasting two or more days. But today’s heat waves are breaking records and pushing power grids to the limit.

According to the National Oceanic and Atmospheric Administration (NOAA), the U.S. has seen a dramatic increase in the number of 90+ degree days in the past 50 years. Climate experts point to global warming as the driving force behind this dangerous trend. Rising greenhouse gas emissions are trapping more heat in our atmosphere, and cities — packed with concrete and asphalt — are heating up faster than ever.

Who’s at Risk?

Anyone can suffer from heat-related illness, but some groups are especially vulnerable:

  • Older adults, especially those over 65
  • Young children and infants
  • People with chronic conditions, such as heart disease, diabetes, or respiratory issues
  • Outdoor workers and athletes
  • Low-income families without access to air conditioning

Knowing the signs of heat illness can help save lives. Look out for symptoms like dizziness, nausea, confusion, rapid heartbeat, or a throbbing headache. These could be early signs of heat exhaustion — or even heat stroke, which is a medical emergency.

7 Ways to Stay Safe When It’s Scorching Outside

You don’t need to suffer through the summer. Here’s how to stay cool and safe when the temperatures rise:

  1. Hydrate like it’s your job
    Drink water throughout the day — even if you’re not thirsty. Avoid sugary drinks and alcohol, which can actually make dehydration worse.
  2. Avoid the sun during peak hours
    Try to stay indoors between 10 a.m. and 4 p.m. when the sun is strongest. If you have to be outside, wear a wide-brimmed hat and lightweight, loose-fitting clothes.
  3. Use fans, but don’t rely on them alone
    Fans can help, but when the temperature climbs into the high 90s or above, they won’t prevent heat-related illness. If you don’t have air conditioning, consider going to a local cooling center, library, or shopping mall.
  4. Take cool showers or baths
    A quick rinse under cold water can lower your body temperature fast. You can also use wet washcloths on your neck, wrists, and forehead.
  5. Check on neighbors and loved ones
    Seniors living alone are at high risk during heat waves. A quick call or visit can make all the difference.
  6. Watch for symptoms
    If you or someone else shows signs of heat stroke — hot, dry skin, confusion, or unconsciousness — call 911 immediately. Don’t wait.
  7. Plan your errands wisely
    Grocery runs and appointments should be done early in the morning or later in the evening. Don’t sit in a hot car — even for a minute.

What Are Cities Doing About It?

Some cities are stepping up with programs to help residents cope with the heat. For example, New York City offers a “Cool Neighborhoods” program  that plants trees, installs reflective rooftops, and operates cooling centers in underserved areas. In Phoenix, hydration stations are being set up to provide free water to the homeless and low-income residents.

Still, many public health experts warn that more needs to be done. Expanding access to air conditioning and investing in green infrastructure are key to keeping communities safe in the long term.

Bottom Line: Don’t Underestimate the Heat

Extreme heat is now one of the deadliest types of weather in the U.S., causing more deaths each year than hurricanes, floods, and tornadoes combined. But the danger can be avoided — if we treat heat waves with the seriousness they deserve.

So this summer, don’t just stock up on sunscreen. Check the forecast, take precautions, and keep yourself and your loved ones safe when the heat’s on.
