DEATH VALLEY NATIONAL PARK, Calif. — Ray Estrada’s 11-year-old grandson is used to Las Vegas’ scorching summers, but he’d always wanted to experience the heat in one of the Earth’s hottest places. So Estrada recently drove him to Death Valley National Park<\/a>, with an umbrella, extra water and electrolytes in tow. That day, the thermometer soared to 118 F (47.78 C).<\/p>\n

\u201cWe have to be very careful when we go out there,\u201d Estrada told him. \u201cIf you start feeling dizzy or whatever… we\u2019re just gonna turn back and be safe so we can do this again another time.\u201d<\/p>\n

The extreme temperatures in this stretch of California desert attract visitors every year, some determined to finish a grueling, multiday race<\/a>, others just curious about the sizzling heat and the landscape’s vast beauty. Yet despite the warnings, the heat kills one to three people annually, and park rangers respond to overheated visitors multiple times per week, making communication about heat safety a priority for the National Park Service. <\/p>\n

But that’s easier said than done.<\/p>\n

\u201cIt\u2019s very easy to underestimate how dangerous heat is,” said Abby Wines, the park’s acting deputy superintendent. \u201cPeople are usually used to thinking of heat as something that makes them uncomfortable,” and that they can tough it out. <\/p>\n

\u201cThis type of heat will kill,\u201d she said. <\/p>\n

Death Valley holds the record for the hottest temperature ever officially recorded \u2014 134 F (56.67 C) in July 1913 \u2014 although some experts have disputed it and say the real record was 130 F (54.4 C) there in July 2021. <\/p>\n

In the U.S., heat kills more people than other weather events combined, according to the National Oceanic and Atmospheric Administration. If planet-warming greenhouse gas emissions, which come from burning fuels like oil and coal, continue at their current pace, more places could experience broiling temperatures. That makes it crucial to communicate the dangers of extreme heat and safety precautions, as both can influence who lives and dies. <\/p>\n

Throughout this desert are stark warnings of the deadly heat: \u201cStop. Extreme heat danger. Walking after 10 a.m. not recommended,\u201d one sign says. \u201cHEAT KILLS!\u201d warns another. On bathroom walls there are reminders to hydrate in the form of charts displaying the color of pee \u2014 the darker the urine, the more you need to drink water.<\/p>\n

Another sign warns visitors that helicopters for medical emergencies can\u2019t safely fly amid extreme temperatures. Ambulances can often deploy in extreme heat but are not a guarantee. The safety of emergency responders is always considered.<\/p>\n

Baruch Fischhoff, professor at Carnegie Mellon University who studies decision-making, said evidence shows that people generally underestimate risk when they have a sense of control. Information that explicitly says rescue might not be an option if it\u2019s too hot \u201ctakes away that sense of the control that can lead to underestimating risk.\u201d <\/p>\n

Failing to recognize those risks can be deadly. Last summer<\/a>, a helicopter was unable to fly to a rescue because of 128 F (53.33 C) temperatures. A group of visitors were traveling on motorcycles when one died from the heat, and another was treated for severe heat illness and transported to a hospital.<\/p>\n

Rescue options are even more limited for hikers lost on a trail. Unless it\u2019s a short distance and rescuers know where the person is, they\u2019ll likely wait until sunset if it\u2019s above 115 F (46.11 C). \u201cDepending on their situation,\u201d Wines said, that’s \u201cprobably too late.\u201d <\/p>\n

Two of the park’s busiest months are in the summer, and it sees a small bump in visitors when temperatures are expected to hit the high 120s or 130s F (48.89s to 54.44s C). But it’s the moderate temperatures that tend to get people into more trouble. <\/p>\n

\u201cWe actually have a harder time communicating our concerns about heat to the public when they visit and it\u2019s only 100 to 115,” Wines said. The dryness evaporates sweat almost instantly, so many people don’t realize how much they’re actually sweating. <\/p>\n

Then there’s the vastness. Death Valley has more than 50 entrances, so many visitors aren’t seeing rangers who can relay important information. Instead, they place heat warning signs in the hottest and most popular spots. But they discovered that people responded less to heat warning signs that looked permanent compared to those that seemed temporary. <\/p>\n

For Marc Green, an expert in experimental psychology, that finding is \u201c100% predictable.\u201d <\/p>\n

\u201cPeople judge what to do based on specific information,\u201d he said. If a warning sign is up all the time, even when conditions are good, it contains no useful information. \u201cThat’s why people disregard it.\u201d <\/p>\n

Jennifer Marlon, senior research scientist at the Yale School of the Environment, has studied public perceptions<\/a> of the health risks of extreme heat across the U.S. How people perceive heat and other climate risks varies by factors like age, race, gender, income level and where they live. Older white men, for instance, tend to have lower risk perceptions across the board, whereas women have higher risk perceptions than men. <\/p>\n

\u201cThe challenge, though, is that the level of worry or risk perception doesn\u2019t necessarily translate into action,\u201d Marlon said. Optimism bias could also falsely make a person believe the heat won\u2019t personally affect them. While studies show that experience with heat increases people\u2019s concern, it is short-lived. <\/p>\n

\u201cYou get a bump for like a year or so after a really big event and then it just goes right back to the baseline,\u201d she said. <\/p>\n

Marlon said to be specific. Don’t just tell people that heat can be lethal, tell them what could happen to their bodies and what to do to stay safe. <\/p>\n

Death Valley park does this. On site and online<\/a>, park officials tell visitors to avoid hiking at low elevations after 10 a.m., to stay on paved roads and near their cars. They say to drink and carry plenty of water, and to seek shade and hydrate if you feel dizzy, nauseous or have a headache. <\/p>\n

And while this isn’t something the park would initiate, if scientists gave names to heat waves, similar to how hurricanes are named, that could better grab people\u2019s attention because human brains are attuned to novelty, Marlon said.<\/p>\n

The messenger is also important. If friends, family and neighbors are worried and nudging you to do something, that can be more powerful than reading information online. Community leaders modeling appropriate behavior \u2014 like saying they\u2019re evacuating their family ahead of a hurricane or that they carry extra water in their trunk \u2014 can also go a long way.<\/p>\n

Marlon also suggested communicating how extreme heat can impair the ability to think clearly. When communicating with images, show people drinking water, putting on cold wet towels or resting in shade. <\/p>\n

\u201cWhatever the recommended behavior is, show them pictures of that behavior because we\u2019re incredibly and fundamentally social animals, and body language is so much of how we communicate,\u201d Marlon said.<\/p>\n
