Heat stress vulnerability and critical environmental limits for older adults

S. T. Wolf, R. M. Cottle, et al.

This research conducted by S. Tony Wolf and colleagues highlights the increased heat stress vulnerability in healthy older adults compared to their younger counterparts. The study reveals critical environmental limits for older adults during minimal activity, providing evidence-based recommendations to reduce heat-related risks indoors. Discover how to protect our aging population from heat hazards!

Abstract
This study examined heat stress vulnerability in healthy older adults compared to young adults, characterizing critical environmental limits for older adults indoors at rest and during minimal activity. Fifty-one young (23 ± 4 yrs) and 49 older (71 ± 6 yrs) adults underwent progressive heat stress in an environmental chamber. Older adults showed increased heat vulnerability (p < 0.01), with lower critical environmental limits during minimal activity than young adults (p<0.0001) and lower than at rest (p < 0.0001). These findings define critical environmental limits for older adults in indoor settings, informing evidence-based recommendations to mitigate heat-related harm.
