Studies: Physical Activity Improves Health

This article on the CNN website highlights the fact that physical inactivity causes 1 in 10 deaths worldwide, according to a series of studies released in British medical journal The Lancet, putting it on par with the dangers of smoking and obesity. The results also suggest that public health officials treat this situation as a pandemic.

Specifically, Harvard researchers say, inactivity caused an increase in deaths from coronary heart disease, type 2 diabetes, breast and colon cancers and caused more than 5.3 million deaths in 2008 worldwide.

Also in the spirit of the benefits of living an active lifestyle, this article shows that older adults who are physically active are much less likely to suffer from dementia.

“The key finding is that physical activity may be a preventative strategy for dementia, and it is a relatively easy behavioral modification we can all do,” said the study’s lead author Mary Elizabeth Bowen, Ph.D., research health science specialist at James A. Haley Veterans Hospital in Florida. “There is also evidence that physical activity has cognitive benefits even if a person has other health concerns.”
