When the mercury rises and the air turns still and stifling, communities brace for an invisible but deadly force: extreme heat. It doesn’t tear through towns like a tornado or leave dramatic wreckage in its wake, but its impact is just as devastating. In fact, heat waves are the deadliest weather-related events in the U.S., claiming more lives each year than hurricanes, tornadoes, floods, or lightning.
For vulnerable populations—infants, the elderly, outdoor workers, the unhoused, and those without air conditioning—a prolonged stretch of high temperatures can quickly become life-threatening. Energy grids become strained, water supplies run low, and entire regions scramble to stay safe, hydrated, and cool.
Unlike other weather events, heat waves don’t destroy homes and properties, but they endanger people — quietly and quickly. During extreme heat waves, families, first responders, and community leaders must act fast, relying on critical supplies for cooling solutions, hydration, medical attention, and care for those at highest risk.
Heat Waves Are Increasing, And So Is the Risk
According to the U.S. Global Change Research Project, heat waves are growing in frequency, intensity, and duration, a trend fueled by climate change. Greenhouse gas emissions continue to raise global temperatures, resulting in more hot days and less cooling at night, especially in urban areas.
Key contributors include:
- Urban Heat Islands: Asphalt and concrete absorb and retain heat, trapping warmth even after sunset.
- Deforestation and Land Use Changes: Less greenery means less shade and natural cooling.
- Increased Energy Demand (Driven in Part by the Popularity of AI): As cooling needs surge, power grids can become overwhelmed, leading to dangerous blackouts and brownouts. Increased energy demand also requires more use of fossil fuels when clean energy sources fall short, compounding greenhouse warming trends.
Vulnerable Regions Across the U.S.
Heat waves are no longer rare spikes in the weather. Rather, they’re becoming a seasonal certainty in many regions. Communities nationwide are facing longer, more intense, and more dangerous heat events.
While no area is immune, the Southwest, Midwest, and Southeast are especially hard-hit. Cities like Phoenix, Las Vegas, Houston, and St. Louis have experienced record-breaking heat in recent years. In 2024 alone, the Phoenix metro area endured 113 consecutive days of 100°F or higher, with 70 days reaching 110°F or higher — its hottest summer on record.
Urban areas are at even greater risk. The urban heat island effect means city nights offer little relief, compounding health risks day after day. As these trends accelerate, preparedness becomes more than just helpful; it’s essential.
Extreme Heat Relief Essentials: Ideas That Make a Difference
Whether you’re a nonprofit, relief organization, shelter, or community-focused business, understanding what’s needed during a heat wave emergency can, quite literally, save lives.
Create Cooling Centers
When air conditioning is unavailable or the power grid fails, having cool, safe spaces becomes a lifeline.
- Pop-Up Tents and Tarps: Offer instant outdoor shade and UV protection where buildings aren’t accessible.
- Portable Canopies with Misting Systems: Reduce heat exposure and rapidly lower body temps.
- Solar- or Battery-Powered Cooling Fans: Keep air circulating when electricity is limited.
- Portable A/C Units or Swamp Coolers: Crucial for cooling shelters, especially where groups gather or sleep.
Prevent Heat Stroke and Illness
Keeping body temperatures in check is essential to preventing heat exhaustion or worse.
- Cooling Towels and Ice Packs: Help regulate body temperature and offer quick relief when symptoms arise.
- Sun Hats, Sunglasses, and Lightweight Clothing: Protect skin from exposure and reduce heat absorption.
- Electrolyte Packets and Hydration Tablets: Replenish vital minerals lost through sweat.
- Sunscreen and SPF Lip Balm: Prevent sunburn, especially in outdoor relief sites.
Hydration and Nutrition Essentials
Hydration is non-negotiable. Even brief periods without water can become critical.
- Bottled Water and Large Dispensers: Ensure a constant supply of clean drinking water.
- Reusable Water Bottles: Encourage regular hydration with items ideal for long-term use.
- Hydration Drinks: Electrolyte-rich beverages help quickly replace lost fluids, which is especially critical for seniors, children, and those with chronic health conditions.
- Low-Sodium, Non-Perishable Snacks: Options like tuna packets, granola bars, and trail mix provide nutrients without increasing dehydration risk.
Support the Most Vulnerable
Certain populations face greater challenges during extreme heat, including young children, pets, the elderly, and those with limited mobility.
- Personal Cooling Devices: Provide portable relief with handheld fans, neck coolers, and cooling vests.
- Thermometers and Heat Stress First Aid Kits: Allow for quick monitoring of heat-related symptoms and expedite immediate care.
- Baby Essentials: Caregivers need diapers, formula, baby sunscreen, and fans for strollers, cribs, or car seats.
- Pet Cooling Mats and Hydration Bowls: Don’t forget the four-legged family members, who may have difficulty regulating their body temperatures.
