Heatwaves already push seniors past deadly thresholds, new study finds
TL;DR
A Nature Communications study re-examined six extreme heatwaves from 2003–2024 and found that when accounting for humidity, the body’s cooling ability, and age, these events contained non-survivable periods for people over 65, even without reaching the previously assumed 35 C wet-bulb limit. The findings suggest current heat risks are higher than earlier estimates and that heat-related deaths may be underreported, underscoring the need for stronger adaptation in hot and humid regions.
