CNN covered a study by Eunyoung Choi and Jennifer Ailshire, which found that extreme heat may silently accelerate biological aging at the molecular level, with effects comparable to smoking and heavy alcohol consumption. If people can change or find ways to adapt to their heat exposure levels, it may be possible to slow or reverse the accelerated aging process, Ailshire said. “Because that’s not permanent damage; it’s an indicator of the potential for permanent damage. It doesn’t necessarily signify that this damage has been done.”
