Living through extreme heat waves can [1]accelerate your rate of aging , according to research published Monday. From a report:
> Scientists analyzed 15 years' worth of health data from nearly 25,000 adults in Taiwan and found that two years of exposure to heat waves could speed up a person's so-called biological aging by eight to 12 extra days. It may not sound like a lot, but this number builds over time, said Cui Guo, an assistant professor at the University of Hong Kong who led the study, which was [2]published Monday in the journal Nature Climate Change .
>
> "This small number actually matters," she said. "This was a study of a two-year exposure, but we know heat waves have actually been occurring for decades." The research comes as human-induced climate change is making heat waves more intense and long-lasting. The West Coast of the United States is suffering from sweltering temperatures while Iran is experiencing searing heat. Record-breaking temperatures punished Europe, Japan and Korea earlier this month. France recently experienced its second heat wave of the summer, sparking a national debate over air-conditioning.
