Heat Exposure May Speed Up Aging, Study Finds
Extreme heat is doing more than just making us uncomfortable. A new study published on August 26 in Nature Climate Change shows that frequent exposure to heatwaves may speed up the aging process. In fact, the more heat a person faces over time, the more their body shows signs of early aging and poor health.
Workplaces at Risk, WHO Issues a Warning
Climate change is causing more frequent and intense heatwaves. As a result, workers worldwide are facing greater health risks. A joint report from the World Health Organization (WHO) and the World Meteorological Organization (WMO) highlights how extreme heat at work leads to stress, illness, and reduced productivity.
Surprisingly, this is WHO’s first full report on heat stress at work since 1969. Therefore, the agency is calling for urgent action. It recommends that governments, employers, and workers work together to create heat safety plans.
Older Adults Need Better Heat Protection
In another review published August 20 in PLOS Climate, researchers found that older adults are especially at risk. Most studies focus only on personal actions like staying hydrated, using fans, or relocating. However, broader solutions such as heat action plans and public warnings are still lacking.
As people age, their ability to cope with heat drops. Some medications and health conditions can make the problem worse. This makes older adults even more vulnerable during heatwaves.
A Wake-Up Call for Everyone
According to WHO’s climate director, Rüdiger Krech, these findings should be a wake-up call. We must act now to protect people from the growing danger of extreme heat and aging.
