A recent investigation by NPR has uncovered a significant discrepancy between reported and actual heat-related deaths in the U.S. The study found that people are dying from heat at a much higher rate than official counts indicate. Further details about the investigation and its findings are available, including the reasons behind the underreporting and potential measures to prevent such deaths.

The investigation spanned two years, tracking heat-related deaths to better understand the issue and explore ways to save lives.
