Nautilus discusses how extreme heat can alter our bodies at the molecular level. The article highlights a USC Leonard Davis School study co-authored by Eunyoung Choi and Jennifer Ailshire, which found that older adults in areas with frequent heatwaves experience accelerated biological aging. The study indicates that living in regions with more than 140 days of temperatures exceeding 90°F per year can lead to over a year of additional biological aging compared to those in cooler areas.
