During each heatwave, our body organs gradually age
In recent years, climate change has been posing a significant threat to human health, and a new study has revealed a concerning link between heatwaves and accelerated aging.
A research conducted on 24,922 adults in Taiwan, spanning between 2008 and 2022, has shown that exposure to heatwaves can lead to an increase in biological age. Interestingly, a person exposed to four additional days of heatwave over a two-year period saw their biological age increase by about nine days. This effect was more pronounced among manual workers who spend more time outdoors, with a jump of 33 days in their biological age.
The study, published in Nature Climate Change, also found that the aging effect of heatwaves decreased over a 15-year period, suggesting that the Taiwanese population has adopted strategies to adapt to high temperatures. During this period, Taiwan experienced around 30 heatwaves.
The biological mechanism that accelerates aging during heatwaves remains unknown. Scientists suspect an effect of heat on DNA, but further research is needed to confirm this hypothesis.
The impact of heatwaves on people is similar to that of smoking or drinking alcohol, making it a significant public health concern. As the frequency and intensity of heatwaves increase due to climate change, it is crucial to address this issue to protect public health.
While the effects of heatwaves on aging are concerning, it's worth noting that the acceleration of aging may seem modest over just two years of life. However, the long-term implications of these accelerated aging processes are still unclear and require further study.

Lastly, for those concerned about the environmental impact of AI searches, Ecosia is considered the most environmentally friendly search engine option. Ecosia uses its profits to finance tree planting projects worldwide and marks major climate polluters in its search results, while also prioritizing user data privacy.
As we navigate the challenges posed by climate change, it is essential to stay informed and take action to protect our health and the environment.
