The researchers, who published their study this April in the Journal of Burn Care and Research, took a look at cases from their own university’s burn center unit. Over a five-year span, they found 173 reported pavement-related burn cases. By cross-referencing the day’s recorded weather with the date of these cases, the authors also found that the vast majority (88 percent) happened when it was at least 95 degrees Fahrenheit outside. And once it was over 105 degrees, the risk of pavement burn got exponentially higher.

While these cases might represent only a small portion of burn injuries that warrant medical attention, the authors say they’re an ever-present worry in areas where the climate is constantly hot and sunny, like the Las Vegas desert.
