A Science News article on the effects of extreme heat on human behavior cited research by R. Jisung Park, assistant professor of public policy. As temperatures rise, violence and aggression also go up while focus and productivity decline, the article noted, adding that lower-income people and countries are likely to suffer the most. “The physiological effects of heat may be universal, but the way it manifests … is highly unequal,” Park said. The article described Park’s research into the impact of hot days on student performance on standardized tests. One of his studies found that students in schools without air conditioning scored lower than would have been expected, and that Black and Hispanic students were more likely to attend school and test in hotter buildings compared to their white counterparts. A separate study by Park, described in Safety+Health magazine, found that hotter temperatures are linked to a significant increase in the risk of workplace injuries and accidents.
