Summary

A new study in Science Advances finds that prolonged heat exposure accelerates aging at the molecular level, similar to smoking and drinking.

Researchers analyzed DNA from 3,600 older adults and found those in hotter areas, like Phoenix, aged 14 months faster than those in cooler places.

Heat-induced “epigenetic aging” increases risks for diseases like dementia and heart problems. Climate change is worsening heat exposure, especially for older adults, further straining health systems.

Scientists aim to study how indoor heat affects health and explore ways to mitigate long-term damage.

    There is a reason why these places were sparsely populated prior to indsutrit revolution…

    Between heat and lack of water, I don’t see how these places are viable long term.

    Midwest is the long term bet imho

      Parts of the midwest but don’t make the mistake of thinking being far away from coasts make you safer.

      The ocean is a massive heat sink, it stabilizes shocks to a regional climate systems and slows them down with the mass and inertia of water.

      Parts of the midwest are great but the narrative that the midwest is lowkey the best place to live during this climate acceleration is hopeful thinking without good evidence.

      …but yeah it definitely is a decent place to survive climate change, im not bashing the midwest.

        I don’t know any placed better… Good agricultural land and temperate climate.

        But yeah nowhere gonna be perfect when food chains collapse
