Heatwaves are increasing with climate change, and that could mean more deaths among older people with diabetes or heart disease, new research shows.
The study of U.S. veterans living in California found the largely male cohort vulnerable, especially if they were homeless or living in poorer neighborhoods.
Compared with cooler days, the typical California veteran living in a disadvantaged neighborhood faced a 44% higher odds of dying during a very hot day, the study found.
Often, these poorer neighborhoods are located in cities that create "urban heat islands" on sweltering days.
