In this free, 30-minute webinar held on June 26, 2025, author and senior policy analyst Dr. Vennela Thumula discussed WCRI's recent research, Heat-Related Illnesses in the Workplace, on the connection between high temperatures and heat-related illnesses (HRIs) in the workplace.

The webinar addressed the following questions:

  • What is the effect of excessive heat on HRIs versus broader heat-related accidents?
  • What role does geographic region play in the frequency of HRI claims?
  • Are certain age groups, genders, or industries more at risk?
  • How does job tenure—particularly two or fewer months on the job—influence the likelihood of HRIs?

The study draws on data from WCRI’s Detailed Benchmark/Evaluation (DBE) database, which includes workers’ compensation claims from various insurers, state funds, and self-insured employers across 31 U.S. states—accounting for approximately 80 percent of national workers’ compensation benefits. Temperature data were used alongside claims data to assess patterns and risk factors associated with excessive heat.
