“The study, published in Nature Climate Change, suggests that moderate increases in cumulative heatwave exposure increase a person’s biological age — to an extent comparable to regular smoking or alcohol consumption.”
“The study, published in Nature Climate Change, suggests that moderate increases in cumulative heatwave exposure increase a person’s biological age — to an extent comparable to regular smoking or alcohol consumption.”
Repeated heatwaves can age you as much as smoking or drinking
Long-term study suggests that the more heatwaves people are exposed to, the more it accelerates body ageing.
