Extreme heat may be accelerating aging in older adults: Study

A study from the USC Leonard Davis School indicates that greater exposure to extreme heat can accelerate biological aging in older adults, impacting their long-term health and age at the molecular level.
Jennifer Ailshire, the study's senior author, notes that individuals in hotter regions show greater biological aging than those in cooler areas.
The research found that older adults in Phoenix faced up to 14 months of additional biological aging compared to those in cooler regions due to higher heat days.
Ailshire emphasizes the need for improved urban infrastructure to protect vulnerable populations from heat exposure as climate change increases.

Does intense heat make people age faster?

According to a new study, extended exposure to intense heat speeds up biological ageing. These effects are most noticeable in older people. These findings are crucial because a higher biological age than chronological age is linked to an increased risk of illness and death

Biological age model using explainable automated CT-based cardiometabolic biomarkers for phenotypic prediction of longevity

We derive and test a CT-based biological age model for predicting longevity, using an automated pipeline of explainable AI algorithms that quantifies skeletal muscle, abdominal fat, aortic calcification, bone density, and solid abdominal organs. We apply these AI tools to abdominal CT scans from 123,281 adults (mean age, 53.6 years; 47% women; median follow-up, 5.3 years). The final weighted CT biomarker selection was based on the index of predi…

Extreme Heat Might Be Aging You 14 Months Faster, USC Scientists Warn

USC researchers report that residents in neighborhoods with more high-heat days exhibit accelerated molecular aging compared to those in cooler areas. A study from the USC Leonard Davis School of Gerontology finds that greater exposure to extreme heat may accelerate biological aging in older adults. The findings raise concerns about the long-term health effects of [...]
