A recent study published in The Lancet Global Health has warned that climate change and rising global temperatures could significantly reduce physical activity levels across the world by 2050. Countries with hot climates, including India, are expected to face a greater impact as extreme heat discourages outdoor movement and exercise.
The study highlights that increasing heatwaves and prolonged high temperatures make walking, outdoor work, and physical exercise more difficult, pushing people toward sedentary lifestyles. In India, adult physical inactivity could rise by nearly two percentage points by 2050—higher than the global average—posing serious public health challenges.
Globally, nearly one in three adults already fail to meet recommended activity levels. Climate-driven reductions in physical movement may worsen risks of heart disease, type 2 diabetes, obesity, certain cancers, and mental health issues such as stress and depression. The study cautions that these combined effects could lead to hundreds of thousands of premature deaths worldwide.
The findings underline a growing link between climate change and lifestyle-related health risks, especially in urban areas where inactivity is already common. According to World Health Organization, adults should engage in at least 150–300 minutes of moderate physical activity per week, such as walking or cycling, to maintain good health.
Overall, the study emphasizes that climate adaptation strategies must also focus on protecting public health by enabling safe and sustainable ways to stay physically active in a warming world.
