Light and moderate physical activity reduces the risk of early death

August 12, 2010

Even light or moderate intensity physical activity, such as walking or cycling, can substantially reduce the risk of early death, a new study by researchers from the London School of Hygiene and Tropical Medicine (LSHTM), Cambridge University and the Karolinska Institute in Sweden has found.

The study,  published this week by the International Journal of Epidemiology, combined the results from the largest studies around the world on the health impact of light and moderate intensity physical activity. It showed that the largest health benefits from light or moderate activity (such as walking and cycling) were to people who do hardly any physical activity at all. Although more activity is better, the benefits of even a small amount of physical activity are very large in the least physically active.

The good news from this study is that you don’t have to be an exercise freak to benefit from physical activity. Just achieving the recommended levels of physical activity (equivalent to 30 minutes daily of moderate intensity activity on 5 days a week) reduces the risk of death by 19%, while 7 hours per week of moderate activity (compared with no activity) reduces the risk of death by 24%.
