Spotlight on Research Into Heat-Triggered Injuries

Research into the effects of hot weather on workplace injuries, led by Assistant Professor of Public Policy R. Jisung Park, drew widespread media attention. Park’s study found that extreme heat causes many times more workplace injuries than official records capture and that those injuries are concentrated among the poorest workers — the latest evidence of how climate change worsens inequality. Hotter days lead to an additional 20,000 workplace injuries each year in California alone, not just among people who work outdoors but also for indoor workers, endangering those employed in manufacturing, warehousing and wholesale, the study found. High temperatures were linked to injuries from falling, being struck by vehicles or mishandling machinery, in addition to heat stroke, suggesting that heat makes it harder to concentrate. “Hotter temperatures … appear to have hidden costs,” Park told the Los Angeles Times. Several other news outlets also showcased the research, including the New York Times, the Guardian, Marketplace and Vox.
