Hot weather significantly increases the risk of accidents at work and injuries, according to a study released on Friday by the University of California-Los Angeles.
Using data from the California Workers' Compensation System from 2001 to 2018 and government weather data, researchers from UCLA found that the incidence of compensable injuries increased by 6% to 9% on days when the temperature was above 90 degrees Fahrenheit compared to days when the temperature was at 50s or 60s. When the temperature is above 100 degrees, the risk of injury increased by 10% to 15%, regardless of whether the work was performed inside or outside.
The study also noted that heat-related injuries decreased after 2005 when California implemented mandatory measures to prevent heat illness.
Researchers estimate that high temperatures in the state currently cause about 1
