Extreme Heat Accelerates Aging, Study Finds

Douglas McIntyre, Editor-in-Chief at Climate Crisis 24/7, reports on a new Advanced Sciences study linking extreme heat to accelerated aging. The research suggests that prolonged exposure to temperatures above 90 degrees can alter DNA, potentially aging individuals by up to six years over a lifetime. With climate change driving longer and more intense heat waves—such as Phoenix’s record-breaking 100 consecutive days over 100 degrees—this trend is likely to worsen, affecting more regions in the coming years.
