Scientists warn: reducing physical activity in heat may cause long-term health risks
With expected temperature records this summer due to El Niño, scientists caution that frequent cessation of exercise in hot weather could lead to serious consequences, including increased risk of premature death.
During the 2026 FIFA World Cup, set to take place in the United States, Canada, and Mexico, players will receive additional water breaks at the 22nd minute of each half to combat heat. This summer, new temperature records are anticipated due to a strong El Niño climate pattern, making outdoor sports a significant challenge.
However, scientists warn that reducing physical activity every time it is too hot outside could pose long-term health risks. Climate change-driven temperature rises may lead people to move less in the heat, potentially increasing premature death rates. Researchers estimate that by 2050, such deaths could reach between 470,000 and 700,000 per year.
