US EditionStudy: Physical Inactivity Due to Rising Heat to Kill 500K
A global study projects that each month above 27.8°C could increase inactivity by 1.5%, causing up to 700,000 premature deaths and $3.68 billion in productivity losses annually by 2050.
- A new modelling study projects rising temperatures could cause 0.47–0.70 million premature deaths annually and US$ 2.40–3.68 billion in productivity losses by 2050, according to researchers from The Lancet Global Health.
- Using data from 2000–2022 across 156 countries, the study analyzed WHO surveys and Climatic Research Unit temperature records to model temperature impacts through 2050.
- The model shows sharper rises in already hot regions where inactivity could climb by more than four percentage points per month above the 27.8°C threshold.
- Tropical low- and middle-income countries face the steepest impacts, worsening inequities as only about 65% meet WHO exercise guidelines and inactivity causes roughly 5% of deaths.
- Designing cooler cities and expanding climate-controlled exercise spaces are recommended for policymakers and urban planners, as "Greater adaptive capacity, such as air conditioning, climate-controlled gyms and indoor physical activity infrastructure, buffers the effect," García-Witulski said.

Extreme heat may keep millions from exercising, linked to 500,000 early deaths yearly
DimaBerlin/Shutterstock.comA hotter world is quietly changing one of the simplest things we do for our health – moving our bodies. For many people, a walk in the park, a jog around the neighbourhood or a cycle to work is becoming harder, and sometimes unsafe, as temperatures rise. Scientists are beginning to understand how heat affects physical activity and why this matters for long-term health. A new modelling study in The Lancet Global Health …
Shafaq News – A recent scientific study has revealed alarming predictions for the future of humanity due to climate change. The study found that rising temperatures will cause hundreds of thousands of deaths annually by 2050 due to physical inactivity. A team of researchers at the Catholic University of Argentina analyzed data from 156 countries over more than two decades (2000-2022) to understand the relationship between rising temperatures and…
Rising temperatures could make millions of people more sedentary, new study finds
New research suggests rising global temperatures are likely to contribute to a decrease in physical activity.A group of researchers in South America studied more than 20 years' worth of temperature and activity data collected from 156 countries across the world. Their goal was to model how the two variables would interact come 2050.The model showed every month the average temperature was higher than 82 degrees Fahrenheit, or 27.8 degrees Celsius…
The Lancet Global Health: Modelling suggests climate change could drive millions globally into physical inactivity by 2050 and be linked to an estimated half a million premature deaths
Rising temperatures due to climate change could drive millions more adults globally into physical inactivity by 2050, being linked to hundreds of thousands of premature deaths and billions of dollars in lost productivity, suggests a modelling study published in The Lancet Global Health journal.
