Study Warns Climate Change Could Cause Up to 700,000 Deaths Annually by 2050 Due to Physical Inactivity
————————————
A new scientific study warns that rising global temperatures linked to climate change could lead to hundreds of thousands of deaths each year by 2050 due to increased physical inactivity.

Researchers from the Catholic University of Argentina analyzed data from 156 countries between 2000 and 2022, examining the relationship between temperature increases and declining activity levels. The study found that each additional month with average temperatures above 27.8°C could raise global physical inactivity by 1.5%.

This trend could result in between 470,000 and 700,000 premature deaths annually, along with economic losses estimated at $3.68 billion per year due to reduced worker productivity.

The researchers explained that higher temperatures place physiological strain on the human body, increasing cardiovascular stress and making physical activity more difficult, particularly outdoors. They also noted that the past three years have been the hottest on record, further limiting opportunities for exercise in many regions.

The impact is expected to be uneven, with low- and middle-income countries facing the greatest risks due to limited infrastructure and adaptation capacity. Regions already experiencing high temperatures—such as Central America, the Caribbean, sub-Saharan Africa, and Southeast Asia—are projected to see the largest increases in inactivity.

The study warned that rising heat could undermine global efforts, including targets set by the World Health Organization to reduce physical inactivity by 15% by 2030.

Researchers called for urgent measures, including climate-adapted urban design, affordable indoor exercise facilities, and public awareness campaigns, stressing that physical activity must be treated as a climate-related public health priority.
