Mexico study finds that heat kills young people more than elderly

MEXICO  — A surprising study of temperature-related deaths in Mexico upends conventional thinking about what age group is hit hardest by heat. Researchers found at higher temperatures and humidity, the heat kills far more young people under 35 than those older than 50. For decades, health and weather experts have warned that the elderly and the youngest children were most vulnerable in heat waves. But this study looking at all deaths in Mexico from 1998 to 2019 shows that when the combination of humidity and temperature reach uncomfortable levels, around 30 degrees Celsius and 50% relative humidity, there were nearly 32 temperature-related deaths of people 35 years old for every temperature-related death of someone 50 and older. The study in Friday’s journal Science Advances shows an especially surprising spike of heat-related deaths in an age group thought to be young and robust: people between 18 and 35. That age group alone had nine times as many temperature-related deaths as those older than 50. Study authors and outside experts are scrambling to figure out why. Demographics alone don’t explain why more young adult Mexicans are dying in high heat than their elders. Two theories: Outdoor workers who can’t escape the heat, and young people who don’t know their limits…Read more
