Effects of climate change on physical inactivity: a panel data study across 156 countries from 2000 to 2022

The Lancet Global Health | April 2026

Physical inactivity represents a major global health challenge. Recent findings indicate that approximately one-third of the global adult population does not adhere to WHO guidelines,1 which stipulate a minimum of 150 min of moderate intensity or 75 min of vigorous intensity physical activity on a weekly basis.2 Physical inactivity is one of the leading modifiable risk factors for non-communicable diseases (NCDs) and is responsible for an estimated 5% of all adult deaths,3 drives US$54 billion in annual direct health-care costs, and generates a further $14 billion in productivity losses.4 Without decisive action, the global prevalence of physical inactivity could rise, threatening the WHO target of a 15% relative reduction by 2030.2
