A new study suggests that just one hour of walking for people over 40 can add up to three years to their lives.
Researchers from Australia examined the relationship between physical activity and lifespan in people over 40 in a study.
The study, published in the British Journal of Sports Medicine, found that if middle-aged people become physically active, their lives can be extended by an average of five years.
The scientists wrote in the study that the results of the study suggest that physical activity has more health benefits than previously thought.
In the study, the scientists developed a predictive model to measure the effects of different types of additional physical activity on lifespan.
Scientists examined data from the National Health and Nutrition Examination Survey of people aged 40 and over from 2003 to 2006.
The data included 2019 population data from the US Census Bureau and 2017 mortality data from the National Center for Health Statistics.
The study found that the most active 25% of Americans over 40 were walking at a moderate pace for 160 minutes a day, up to an hour.
