How to stay cool in heat wave — even without air conditioning

by Naharnet Newsdesk 24 June 2025, 16:48 Climate change has been exacerbating heat waves, and the problem isn't going away anytime soon. An increasingly hot planet — due largely to burning fossil fuels such as coal, oil and natural gas — means already hot regions are getting worse. Heat doesn't just mean canceled events. It also poses a health risk, especially for children, older people and those with certain health conditions. So here are some tips to stay safe. When does heat become dangerous? The answer depends on more than the temperature. The most detailed measurement is called the wet bulb globe temperature (WBGT), which includes temperature, humidity, cloud cover and wind. The heat index, which measures temperature and humidity, is less descriptive but easier to find on weather apps. Both explain why a shaded soccer field on a 90 degree F day (32 degree C) in arid Phoenix may be less risky than an exposed park on an 80 degree F (27 degree C) day in soupy Little Rock. Just based on heat index, NOAA has a chart that calculates how dangerous prolonged exposure can be. For example, a day where temperatures reach 96 degree F (36 degrees C) and 45% humidity would fall into the "danger" category for prolonged exposure or strenuous activity. The WBGT threshold isn't exact, but recent research suggests that even some young, healthy people can't endure hours of exposure to high heat and humidity. How to cool down Overnight lows can be a particularly dangerous part of a heat wave, said Ashley Ward, director of the Heat Policy Innovation Hub at Duke University. "Your body needs a reprieve," she said. "You don't get that overnight, we start the next day at a deficit." Heat can worsen labor productivity and lead to more visits to the emergency room. "When we have overnight temperatures that don't drop below 75 degrees" F (24 degrees C), she said, "you start to see some pretty extraordinary outcomes with respect to heat illness and heat stroke, and even mortality." Ward's answer: Find air conditioning. That might be at home, but she said census data overcounts how many people have access. If you can't afford to cool the whole house, Ward said, create a "cool corner" and sleep there, so your body is prepared to tackle the next day. Evaporative or "swamp" coolers can help in dry heat, but they increase humidity and can make it more difficult to cool down. In humid places, just use a fan. If you don't have air conditioning, find public places that do, including movie theaters, malls and libraries. Some communities set up cooling centers. Depending on where you live, the Low-Income Home Energy Assistance Program can help you buy a window air conditioning unit, according to the National Council on Aging. Some local nonprofits and civic organizations can also help you access one if cost is a burden. Know your rights if you work outside Knowing what workplace protections you have is important. But there are no federal heat rules to protect workers in the United States. Some states have them, including Washington, Oregon, California, Nevada, Colorado, Minnesota and Maryland, according to the National Resources Defense Council. Other states don't have any. If your state has work rules, try to learn them — though there are still challenges to ensuring regulations are actually enforced, said Bharat Venkat, director of the University of California, Los Angeles Heat Lab. He notes that sometimes shaded areas are too far for workers to take breaks without losing wages, or that management can make it impossible for workers to advocate for themselves. "Most workers don't actually have control over their time or control over where they work," he said. Within those constraints, finding ways to stay hydrated and lower your body temperature are paramount. You can do this by drinking lots of fluids, wetting clothing or putting cold water or a cold rag on your hands, feet, armpits and neck. A portable handheld fan or a cooling vest can also help. If you're exercising, avoid the hottest times of day and bring more water than you think you need. Knowing heat illness symptoms Heat illness symptoms can vary by person, Venkat said. Medications or underlying conditions can also make it harder to regulate body temperature or notice you're getting too hot. Early trouble signs include heavy sweating, muscle cramps and headache. That's when you stop what you're doing and cool yourself off — for example, by splashing yourself with cold water or finding an air conditioned space. As heat exhaustion sets in, new symptoms arrive, including faster heart rate and dizziness. Next comes heat stroke, which can include confusion, slurred words and fainting. Ward said that's when to call 911. "Don't be embarrassed to call 911 or go to urgent care when you think you might have overdone it in the heat," he said.

We Are All Now First Responders to Extreme Heat

This week, blistering temperatures could put more than 220 million Americans at risk. Extreme heat is the deadliest type of weather disaster in the United States—and one of the most underestimated. In my decades of climate resilience work in towns and neighborhoods, I've seen firsthand the pain, loss, and economic costs of extreme heat. Heat strains power grids, damages infrastructure, and worsens air pollution. It puts outdoor and commuting workers at risk, flares chronic health conditions, profoundly endangers mother and baby during pregnancy, and disproportionately harms children, older adults, and low-income families. Yet as communities from the Eastern Seaboard to the Midwest are engulfed in record-breaking temperatures, the U.S. is now even more dangerously unprepared. The safety net we count on in moments of climate crisis isn't just fraying—it's unraveling. As a result, you are (or will soon be) forced to become your own first responder. In its drive to slash the size and scope of the federal government, the Trump administration has weakened the very agencies and systems we rely on to prepare for and respond to disasters–including extreme heat. Cuts to NOAA's forecasting programs weaken our ability to anticipate and plan for dangerously high temperatures while reduced support for programs like the Low-Income Home Energy Assistance Program (LIHEAP) and slashed funding for public health efforts—like the CDC's Climate and Health Program—leave states and cities without tools to protect residents before and during heat waves. Read More: Losing NOAA's Natural Disaster Data Will Make Storms More Devastating for the Poor While these cuts may seem abstract or bureaucratic, their impact is personal. If you've ever checked the weather on your phone, you've depended on NOAA. These are the scientists who issue early warnings that save lives. When funding is slashed, those alerts may come too late—or not at all. Even before summer officially began, Americans were grappling with the impacts—from International Falls, Minnesota, known as the 'icebox of the nation,' where temperatures soared into the 90s in early May, to the Rio Grande Valley, which endured a mid-May heatwave that made it hotter than Death Valley. Alaska—yes, Alaska—issued its first ever heat warning this week. Read More: The Most Efficient Way to Run Your AC During a Heat Wave While the administration claims it is shifting responsibility to the states, this blatantly ignores the reality that states lack the funding and infrastructure to manage on their own. Federal grants have been essential to states' preparedness. Even cities widely regarded as leaders in disaster preparedness are strained. Miami-Dade County was forced to eliminate both its Chief Resilience Officer and Chief Heat Officer roles due to budget constraints, while Los Angeles' proposed budget would eliminate its entire climate resilience office. I work with under-served communities around the world, from the United States to India, and Mexico to Greece. I've sat in community centers where mothers have shared strategies on how to stay safe working outdoors while still earning enough to feed their families. I've walked through Sierra Leone outdoor markets and seen the benefit of simple shade structures to prevent heat stroke. These efforts are survival. When governments can't (or won't) help us, we—our communities—become the first line of defense. As a first responder, here's what you can do: Know What's Coming It's important to understand your local climate threats. Arm yourself with information on the early signs of heat illness: dizziness, headache, nausea, rapid heartbeat, and confusion. Heatstroke is a medical emergency that requires immediate action. Awareness saves lives and sparks action. Plan Like It's Personal Heat doesn't just affect 'other people'—healthy, young individuals are now showing up in emergency rooms. Having a plan can save lives. That means staying hydrated, resting in shade or air-conditioned spaces, and scheduling strenuous outdoor activities early in the day. If you don't have air conditioning, know where the nearest cooling center is and how to keep your home cooler—by closing blinds during the day and using fans or cross-ventilation at night, when staying cool is essential for the body to rest and recover. Build a Check-In Culture Loneliness can be lethal during a heatwave. Programs like Philadelphia's Heat Response Program and Los Angeles' senior outreach initiative show how check-ins save lives. But you don't need a government job to do this. Create a phone tree or a group chat. Encourage people to 'adopt a neighbor' during heat alerts. One call can make all the difference. Turn Public Spaces into Lifelines When government systems falter, schools, libraries, religious institutions, and shaded parks can become heat-safe hubs. I've helped cities pilot community cooling spaces that serve as a refuge for people without access to air conditioning and seen how, when designed thoughtfully, cooling centers are not just places to retreat—they are places to reconnect, reorganize, and rebuild. While your new job as a first responder is critical, it's not yours to keep — that's the government's. Until then, however, and while the safety net is burning, it's on us to help put out the flames.

Hot and unprepared

The 'rare' and 'extremely dangerous' heat wave gripping large swaths of the country offers a reminder of the dangers of climate change as the world fails to curb atmospheric pollution. Tens of millions of people across the Midwest and East Coast are experiencing scorching heat today — reaching triple digits in some cities — that could continue through Wednesday. Public health experts are warning people to stay cool and hydrated as temperatures are expected to remain high overnight, offering the body little respite. The heat dome, caused by high pressure in the upper atmosphere that traps heat and humidity, arrives as the Trump administration escalates its assault on regulations designed to combat climate change and protect people from high temperatures. The administration has proposed axing a popular program that helps low-income families heat and cool their homes. The Low-Income Home Energy Assistance Program, which provides support to some 6 million Americans and has bipartisan support in Congress, has increasingly become a source of money to subsidize air conditioning costs as summer heat becomes more dangerous. (The White House has called the program 'unnecessary.') The administration is also weighing the elimination of a proposed rule that would require companies to provide rest and water to outdoor workers in extreme heat. The rule's opponents include the oil and gas industry, among the nation's leading workplaces for heat-related deaths and injuries. Meanwhile, the U.S. and other countries are failing to cut their climate pollution sharply enough to meet the Paris Agreement's goal of keeping global warming 'well below' 2 degrees Celsius. A new analysis from the independent science project Climate Action Tracker found that none of the 40 countries tracked has strengthened its 2030 targets enough to comply with the 2015 climate deal. In Europe, scientists are warning that the continent is wholly unprepared to handle the rapid increase in illnesses and deaths driven by extreme heat, floods and wildfires. Hotter temperatures are also driving the alarming spread of mosquito-borne diseases such as dengue and chikungunya that were once confined to tropical regions. And in the U.S., Trump's efforts to eradicate federal climate initiatives include gutting research programs and firing experts — potentially impairing people's ability to understand how such warming affects the planet. It's Monday — thank you for tuning in to POLITICO's Power Switch. I'm your host, Arianna Skibell. Power Switch is brought to you by the journalists behind E&E News and POLITICO Energy. Send your tips, comments, questions to askibell@ Today in POLITICO Energy's podcast: Dasha Burns speaks with one of Trump's top energy advisers, Jarrod Agen, about the administration's rejection of the GOP's long-held 'all of the above' energy mantra and exclusive embrace of fossil fuels and nuclear power. Power Centers Oil prices yo-yo amid U.S.-Iran tête-à-têteOil prices fell sharply Monday afternoon following an Iranian counterattack against U.S. military bases in Qatar and Iraq, an apparently symbolic move that spared shipments of Middle Eastern crude, writes Ben Lefebvre. Prices tumbled below $70 a barrel, down more than $5 from the day before when the U.S. military action against Iran's nuclear facilities drove prices higher. As prices ping-pong, Trump — who campaigned on driving down energy costs — has tried to stave off panic by publicly urging his administration to increase domestic oil production, writes Robin Bravender. The president took to Truth Social to demand that the Energy Department 'DRILL, BABY, DRILL!!!' despite oil extraction falling outside that agency's jurisdiction. In a separate post, he directed 'EVERYONE' to 'KEEP OIL PRICES DOWN. I'M WATCHING!' Trump's public pronouncements mark attempts to calm consumers and influence prices, but the reality is presidents are limited in their ability to sway global oil markets. GOP moves could undercut the fossil fuel industryRepublican lawmakers are cracking down on federal aid that the fossil fuel industry lobbied hard for in an effort to stay globally competitive, writes Brian Dabbs. On the chopping block are funds to cut methane emissions and a clean hydrogen tax break, the loss of which some energy experts say could jeopardize the future for U.S. oil and gas and give an edge to China and Europe.
