Exercise, even a little of it, can lengthen your life, a new study suggests.

The Norwegian researchers also found that too much sitting was associated with a higher risk of early death.

“Developing ways to limit sedentary time and increase activity at any level could considerably improve health and reduce mortality,” the study authors concluded.

In the study, the team analyzed data from eight studies that included more than 36,000 adults, aged 40 and older, who were followed for an average of almost six years.

During follow-up, nearly 6% of the participants died. After adjusting for other factors, the researchers concluded that any amount of physical activity, regardless of intensity, was associated with a significantly lower risk of early death.

Death rates fell sharply as total activity increased to an amount that was similar to average activity levels in U.S. men and about 10% to 15% lower than activity levels in Scandinavian men and women, the findings showed.

A similarly steep decline in death rates was associated with increasing amounts of light physical activity up to about 300 minutes (5 hours) a day, and moderate-intensity physical activity of about 24 minutes per day.
