Global warming to cut physical activity, cause 500,000 extra deaths annually by 2050

A study analyzing data from 156 countries projects that increased extreme heat will reduce global physical activity and cause 500,000 additional deaths annually by 2050. The decrease in exercise is expected to be more severe in lower-income regions, amplifying existing health disparities. Policymakers and health officials must address climate impacts on activity levels to prevent escalating health crises.
