Featured research by DRI’s Kristin VanderMolen, Ben Hatchett, Erick Bandala, and Tamara Wall.
In July and August, daytime temperatures along parts of the US-Mexico border can reach as high as 120 degrees – more than 20 degrees above normal human body temperature. For agricultural workers and others who live and work in the region, exposure to these extreme high temperatures can result in serious health impacts including heat cramps, heat exhaustion, heat stroke, and heat-related death.
