Some of the most dangerous weather days for older adults happen in July and August, when temperatures climb higher than expected and stay there for days at a time.
When meteorologists start talking about El Niño, it's worth paying attention, especially if you're an active senior who likes spending time outdoors, or a family member who cares about someone who does. Here's what you need to know to stay safe and keep doing the things you love, even during the hottest stretches of summer.
What Is El Niño, and How Does It Affect Northern New Jersey?
El Niño is a natural climate pattern that starts in the Pacific Ocean. Every few years, ocean surface temperatures near the equator warm up significantly. That shift in water temperature changes wind patterns around the globe, which in turn reshapes weather across entire continents.
For communities in Teaneck, NJ, Hackensack, Englewood, and throughout Bergen County, an El Niño year can mean summer temperatures that run several degrees above normal and heat waves that last longer than usual. Instead of a hot day or two followed by relief, you might see five or six consecutive days where the thermometer pushes past 95°F, with muggy nighttime lows that never fully let your body cool down.
That prolonged heat is exactly what makes El Niño summers more dangerous than ordinary warm stretches.
Why Does Extreme Heat Hit Seniors Harder?
Our bodies are remarkably good at managing heat, up to a point. We sweat, blood vessels near the skin dilate, and our internal thermostat keeps things in balance. But several changes that happen naturally with aging make this cooling system less efficient:
-
Reduced sweat production. Older adults typically sweat less, which means the body's primary cooling mechanism doesn't work as well.
-
Slower circulation. Blood flow to the skin decreases with age, limiting the body's ability to release heat.
-
Chronic conditions. Heart disease, diabetes, kidney issues, and lung conditions can make it harder for the body to handle heat stress.
-
Medications. Diuretics, beta-blockers, antihistamines, and some psychiatric medications can interfere with sweating, hydration, or blood flow. If you take any prescription medication, talk with your doctor about how it may affect your heat tolerance.
-
Reduced thirst signals. Many older adults don't feel thirsty until they're already mildly dehydrated. This is one of the most overlooked risk factors during heat waves.
None of this means you need to stay locked indoors all summer. It means preparation and awareness matter more as the temperatures climb.
Adjust Your Schedule
If you walk regularly, whether around your Teaneck neighborhood, along the paths in Overpeck County Park, or through downtown Paramus, shift your outdoor time to before 9 a.m. or after 6 p.m. during heat waves. The difference between a 7 a.m. walk and a noon walk can be 15 to 20 degrees.
Stay Ahead of Thirst
Don't wait until you feel thirsty to drink water. Keep a water bottle within reach throughout the day and aim for six to eight glasses. If plain water doesn't appeal to you, try adding slices of cucumber or lemon, or eat water-rich foods like watermelon, cantaloupe, strawberries, and chilled soups.
Limit coffee and alcohol during heat waves, as both can contribute to dehydration.
Dress for the Weather
Loose-fitting, light-colored, breathable fabrics make a noticeable difference. A wide-brimmed hat and sunglasses protect you when you do go outside. Sunscreen with SPF 30 or higher prevents sunburn, which impairs the body's ability to cool itself.
Use Air Conditioning Wisely
Air conditioning is the single most effective protection against heat-related illness. If your home doesn't have adequate AC, spend the hottest hours at a library, mall, senior center, or community cooling center. Bergen County typically opens cooling centers during extended heat waves in towns like Hackensack, Fort Lee, and Bergenfield. Check with your local municipality for locations and hours.
What Can Family Caregivers Do During Heat Waves?
If you have a parent or loved one living independently in the Teaneck, River Edge, Leonia, or Ridgefield Park area, heat waves are a good time to check in more frequently. Here are a few things to keep in mind:
-
Call or visit daily during extreme heat, especially if your loved one lives alone. Ask specifically whether they're running their air conditioning. Some older adults avoid using AC to save on electric bills, even when temperatures are dangerous.
-
Check medications. Review your loved one's prescriptions with their pharmacist to understand which ones increase heat sensitivity.
-
Watch for subtle changes. Confusion, unusual fatigue, or irritability can be early signs of heat-related illness. Don't dismiss them as "just being tired."
-
Help stock the fridge. Drop off bottled water, fresh fruit, and easy-to-eat cold meals so your loved one doesn't need to cook over a hot stove.
The risks of staying alone extend beyond finances. They include safety concerns during extreme weather events. If you've been wondering whether your parent might benefit from a community setting where someone is paying attention to these details, exploring the comparison between living alone and community living can be a helpful starting point.
How Do Senior Living Communities Prepare for Extreme Heat?
One advantage of community living that often goes unnoticed is weather preparedness. Senior living communities in Bergen County and throughout New Jersey typically have protocols for extreme heat that include climate-controlled common areas, staff trained to recognize heat-related symptoms, adjusted activity schedules, and regular wellness checks.
For someone living alone, there's no built-in safety net if they start showing signs of heat exhaustion. In a community, there is.
Here are some other potential advantages you might find in a senior living community during hot summers and in every season.
Stay Informed, Stay Cool, Stay Active
El Niño summers may bring extra heat to Bergen County, but they don't have to bring extra risk. The key is preparation: knowing your body, watching the forecast, staying hydrated, and having a plan for the hottest days.
