Researchers from the University of Southern California analysed blood samples from more than 3000 people aged over 56 in the US.
They used a biochemical test called an epigenetic clock to estimate participants’ biological age, before comparing them to their area’s heat index.
Implications for Longevity
With global temperatures rising, these findings raise concerns about the long-term impact on human health. Regions experiencing prolonged heatwaves may see increased risks of age-related diseases, including cardiovascular issues and cognitive decline.
Can You Slow Down Heat-Induced Ageing?
Although moving to cooler climates may not be an option for everyone, there are ways to mitigate the impact of heat:
- Stay Hydrated: Proper hydration supports cellular function and reduces stress on the body.
- Prioritise Cooling Strategies: Use air conditioning, fans, and cooling fabrics to regulate body temperature.
- Optimise Sleep Environment: Cooler sleeping conditions improve sleep quality, which is essential for longevity.
- Consume Antioxidant-Rich Foods: Foods high in antioxidants help combat oxidative stress caused by heat exposure.
Final Thoughts
As climate change continues to push global temperatures higher, understanding the effects of heat on ageing is crucial. This study highlights the importance of taking proactive measures to protect health and longevity in hotter environments.
