A recent study published in Science Advances explores how extreme heat affects older adults, showing those in hotter neighborhoods exhibit accelerated aging at the molecular level. The research analyzed over 3,600 older adults and linked higher temperatures, particularly those above 90 degrees, to significant biological changes indicative of faster aging. The authors estimate that prolonged exposure to extreme heat could result in an increase of up to 14 months in biological age. Through the use of epigenetic clocks from blood samples, the study underscores the impact of climate change on aging and overall health.
A new study suggests extreme heat may accelerate aging in older adults, chemically modifying DNA and increasing the risk for disease and mortality.
The analysis of over 3,600 older adults shows that those in hotter neighborhoods exhibit accelerated biological aging, with impacts tied to climate change-driven heat waves.
A person living in areas reaching 90 degrees or above for 140 days could biologically age up to 14 months faster than those in cooler environments.
The researchers utilized epigenetic clocks derived from blood samples to link environmental heat exposure to accelerated aging and its potential health implications.
