Analysis Puts Tennessee Heat Deaths at 125 a Year, 5 Times Official Count

Summary
About 125 Tennesseans a year likely died from heat exposure between 2018 and 2025, far above the CDC’s recorded average of 25.6, according to an NPR and Boston University analysis.
The gap stems from how deaths are counted: CDC tallies rely on death certificates explicitly mentioning heat, while the new model estimates fatalities in which heat contributed but was not recorded.
Nationwide, the analysis estimated roughly 9,000 annual heat deaths over the same period versus the CDC’s 1,700, with about one-third occurring in Florida and Texas.
Tennessee faces another heatwave this week, with Nashville under an “extreme” heat risk and heat indices above 100 statewide; parts of West Tennessee could top 105.
The findings point to a growing public-health threat as heatwaves become hotter, more frequent and longer-lasting, raising the likelihood of higher death tolls without major emissions cuts.
