Heatwaves accelerate aging, study finds.

Heatwaves accelerate biological aging, affecting billions globally.

Why it matters

  • Heatwaves cause long-term health damage.
  • Vulnerable groups face higher risks.

By the numbers

  • 24,922 adults studied over 15 years.
  • 0.023-0.031 years added to biological age per heatwave exposure increase.

The big picture

  • Climate change increases heatwave frequency and severity.
  • Global health impacts are significant.

What they're saying

  • Impact similar to smoking or poor diet.
  • Disproportionate effects on low-income countries.

Caveats

  • Study limited to Taiwan.
  • Long-term impacts need further research.

What’s next

  • Policies to protect vulnerable groups.
  • More research on adaptation strategies.
