Study Finds Physical Activity Could Add Years to Life Expectancy
Research reveals that increased physical activity could halve mortality risk and extend life expectancy, particularly for the least active individuals.
- Griffith University researchers found that individuals in the most active 25% of the population have a 73% lower risk of death compared to the least active 25%.
- The study used accelerometry data for accurate measurement of physical activity levels, showing benefits twice as strong as prior estimates based on self-reported surveys.
- For those in the least active group, modest increases in activity, such as an additional one-hour walk, could yield significant life-extension benefits.
- Low physical activity levels were found to have health impacts comparable to smoking, contributing to risks for heart disease, stroke, and certain cancers.
- The findings suggest revising national physical activity guidelines and investing in walkable neighborhoods, cycling infrastructure, and accessible public transport to promote active lifestyles.
