“If you can keep them from experiencing heat stress, you’re going to get a lot more productivity out of them,” says Fulcher, noting the benefit to businesses. It’s important to provide employees with water, fans, breaks in cool locations, or the option to adjust their schedules when temperatures rise, she suggests. There are many cheaper alternatives to cooling gadgets too. There were also some small improvements in player performance too.īy and large, employers aren’t yet protecting workers enough from excessive heat, says Juley Fulcher, worker health and safety advocate at Public Citizen, a nonprofit consumer advocacy organization.

In the study, when players used the cooling cap pregame, they had lower skin temperature throughout and felt, on average, 14 percent more comfortable than when they didn’t use it. He explains that cooling the blood vessels in your head helps chill the rest of your body relatively quickly. “The cooling effect is tremendous,” says Flouris. Flouris and colleagues measured this by asking the players to swallow a capsule that could record their core body temperature and broadcast it to a nearby receiving device. In one study, adolescent tennis players wore a cooling cap for 45 minutes until their core temperature dropped by half a degree Celsius. Garments containing phase-change materials are almost always the best option, he says.Ī particularly effective technique isn’t to wear a body vest at all, but to instead cool down a person’s head and neck before physical exertion, Flouris says. They kept sucking vegetation against the workers’ clothing, and the vests were very cumbersome to wear. In that scenario, vests with built-in fans proved problematic.
He has also observed trials involving grape pickers in a Cypriot vineyard. “It varies based on the system that you use, and it also depends on the environmental conditions.”įlouris has studied the use of cooling vests by a variety of workers- including those who helped to build stadiums for last year’s FIFA World Cup in Qatar. However, we’ve seen that the effectiveness varies,” adds Andreas Flouris, an associate professor in the Department of Exercise Science at the University of Thessaly in Greece. Once the cooling substance has done what it can and has warmed up, the vest might in theory make things worse, since the wearer is then left with an unnecessary additional layer of clothing, notes Sarah Davey, an assistant professor at Coventry University in the UK who researches work and exercise in extreme environmental conditions, and who has studied cooling vests.
Cooling garments-vests, hats, and scarves-are among them.Ī lot of the vests require the user to swap out expired cooling components for fresh ones. Millions of workers who toil outside, or in indoor spaces where temperatures can climb to unbearable levels, are increasingly adopting special strategies to cope. And due to climate change and multiple recent heat waves, awareness of those risks is growing around the world. Everyone should be mindful of the risks, he emphasizes. Van Pelt knows that heat stress can be very dangerous. “I love it,” he says, describing how his backpack filled with pesticide or natural repellent seems to amplify the effect: “That backpack is almost pressing the cold into your back. Stepping past velvety green lawns and lagoon-like pools on his rounds, the field training manager at Mosquito Squad, a pest control service, has at times felt like he's “living in an oven.”īut Van Pelt has had respite from the scorching conditions: a cloak of cooling power wrapped around his torso-a vest filled with ice. This summer, while spraying insect-killing chemicals in the gardens of the rich in Greater Scottsdale, Arizona, Van Pelt has endured temperatures well in excess of 110 degrees Fahrenheit.

It’s not the disease-carrying mosquitoes, the scorpions, or the 22-kilogram tanks full of pesticide strapped to his back that Wendell Van Pelt fears.
