Global warming of 1.5 ºC poses high heat stress risk to elderly
A study published in The Lancet Planetary Health warns that global warming of 1.5 ºC poses a significant health risk to the elderly. Research led by Stanford University indicates that approximately 22% of the global population aged 60 and older will experience high thermal stress for at least one month every year at this warming threshold.
Unlike younger adults, who can typically tolerate warming up to 4 ºC, older individuals are vulnerable to harmful heat stress at much lower levels. This vulnerability is due to physiological changes associated with aging, such as decreased sweat production, reduced ability of blood vessels to dilate, and diminished heart performance. These factors can lead to uncompensable thermal stress, where the body's natural cooling mechanisms are overwhelmed, potentially causing organ failure.
In Sweden, a survey by the union Kommunal found that only 26% of safety representatives in elderly care believe their employers are well-prepared for heatwaves, with 57% describing preparedness as poor.
