Boosting Lifespan: How More Physical Activity Could Add Five Years

A new study by Griffith University researchers reveals that increased physical activity could significantly extend lifespan, especially for individuals over 40. The study utilized US-based accelerometry data, providing a more accurate measure of physical activity levels compared to previous surveys. **Findings indicate that individuals in the most active quartile have a 73% lower risk of death** compared to the least active. For the least active group, a single hour of walking could add six hours to their life. **Lead researcher Professor Veerman** states that increasing activity levels to match the most active quartile could potentially lengthen life by around 11 years. This highlights the underestimated power of physical activity in improving health outcomes, even surpassing some known risks like smoking. The study suggests revisiting national physical activity guidelines and calls for greater investment in promoting active lifestyles through walkable environments and efficient public transport systems to enhance longevity and ease pressures on health systems.
