ScienceDaily (July 25, 2010) — 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 that even light or moderate intensity physical activity, such as walking or cycling, can substantially reduced the risk of early death.
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% [95%confidence interval 15% to 24%], while 7 hours per week of moderate activity (compared with no activity) reduces the risk of death by 24% (95% CI 19% to 29%).
Lead researcher, James Woodcock said, "This research confirms that is not just exercising hard that is good for you but even moderate everyday activities, like walking and cycling, can have major health benefits. Just walking to the shops or walking the children to school can lengthen your life -- as well as bringing other benefits for well-being and the environment."
