Aug 27, 2025 A recent study from Taiwan reveals that heatwaves can dramatically accelerate biological aging. Just a few days of extreme temperatures may increase one's biological clock, especially for vulnerable populations. The discussion highlights the broader implications of climate change on health. By distinguishing between aging and getting older, the podcast delves into how heat can impact organ function. The risks are particularly acute for manual workers and rural communities without air conditioning, emphasizing the need to understand the demographics affected.

Episode notes
Heatwaves Raise Biological Age
- A Taiwan study found that heatwave exposure increases people's biological age measured via organ function.
- Four heatwave days across two years raised biological age by about nine days, suggesting cumulative effects.
Small Short-Term Change, Bigger Long-Term Risk
- Researchers warn repeated exposure over decades is likely to cause larger ageing effects than short-term impacts.
- The study measured organ function to show organs acting older after heat exposure.
Who Is Most At Risk
- Vulnerable groups include manual workers, rural residents and those without air conditioning.
- These groups are likely to be worst affected by heat-driven ageing due to higher exposure and less mitigation.
