A new study has found that prolonged exposure to extreme heat can accelerate biological aging. Researchers analyzed blood samples from over 3,600 adults aged 56 or older living in the US and found a correlation between higher heat exposure and increased epigenetic age. The study’s findings suggest that chronic exposure to heat can lead to an acceleration of biological aging by up to 2.48 years, comparable to the effects of smoking.
The study’s lead author, Eun Young Choi, noted that the impact of extreme heat on the body may not be immediately apparent as a diagnosable health condition but could have long-term consequences for overall health and disability. The research highlights the need for further investigation into the factors that influence an individual’s resilience or vulnerability to heat exposure.
To mitigate the effects of climate change-driven heatwaves, the study suggests strategies such as planting more trees, painting rooftops white to reduce urban heat traps, and creating public spaces with air conditioning access. By acknowledging the potential risks associated with prolonged heat exposure, people can take steps to stay safe in a warming world.
