Regular movement brings significant physical and mental health benefits. For grown-ups, it helps prevent and manage chronic conditions such as heart disease, cancer, and diabetes, while reducing symptoms of depression and anxiety and supporting brain health.

For children and teens, being active strengthens bones, encourages healthy muscle growth, and boosts motor skills and cognitive development. Despite these benefits, 31% of grown-ups and 80% of adolescents fail to meet recommended activity levels.

Global targets aim to reduce inactivity by 10% by 2025 and 15% by 2030. If inactivity persists, public healthcare systems could face a cost of roughly US$ 300 billion over a decade.

What Counts as Physical Activity?

The World Health Organization defines activity as any movement generated by muscles that requires energy. This includes walking, cycling, playing sports, commuting, or participating in household tasks. Moderate and vigorous movements both improve health, and everyone can take part, regardless of skill level.

Active lifestyles lower the risk of chronic conditions, while inactivity and sedentary habits contribute to rising rates of illness and place strain on healthcare systems. Increasing activity supports overall health, aligns with global disease prevention goals, and advances Sustainable Development Goals.

Benefits and Risks

Insufficient activity is a leading risk factor for chronic disease mortality, increasing death risk by 20–30%. Regular activity supports:

1. Children and teens – improved physical fitness, cardiovascular health, structural strength, cognitive outcomes, mental well-being, and healthier body composition.

2. Grown-ups and older adults – reduced risk of death, cardiovascular disease, cancer, diabetes, and falls, with improved mental clarity, sleep, and overall health.

3. Pregnant and post-partum women – lower risk of complications, gestational diabetes, pre-eclampsia, depression, and improved newborn outcomes.

Sedentary behavior, like prolonged sitting or reclining, is linked to poorer health:

• Children and teens – increased body weight, lower fitness, poor cardiovascular health, reduced sleep, and behavioral issues.

• Adults – higher risk of death, cardiovascular disease, cancer, and diabetes.

How Much Activity is Recommended?

WHO guidelines detail activity levels for children, teens, adults, older adults, pregnant or post-partum women, and those with chronic conditions. Recommendations include frequency, intensity, and duration to achieve health benefits. Any movement is better than none; all age groups should reduce sedentary time, and muscle-strengthening exercises benefit everyone. For children under 5, guidelines emphasize daily active play, sleep, and limiting screen-based sedentary time.

Global Inactivity Trends

Nearly one-third of adults (1.8 billion people) do not meet recommended weekly activity levels. This is projected to rise to 35% by 2030. Women tend to be less active than men, and inactivity increases after age 60. Among teens, 81% are insufficiently active, with girls less active than boys. Factors influencing activity include personal habits, social, cultural, environmental, and economic conditions.

How Countries Can Promote Activity

Effective policies include ensuring safe walking and cycling routes, access to sports and public spaces, activity opportunities in schools, workplaces, childcare, and healthcare services. Multi-sector collaboration is essential, including government departments, NGOs, and community stakeholders. Priority should be given to reducing disparities, ensuring everyone has the chance to stay active and healthy.

Reflection

Movement is a simple yet powerful tool to enhance health, mood, and longevity. By integrating activity into daily life, communities and individuals can reduce disease risk, improve mental well-being, and create a more energetic, balanced life. Small steps every day can lead to lasting transformation.
