Daily physical activity as light as pushing a shopping cart, vacuuming the house or strolling through a museum can dramatically reduce a person's risk of disability, a new study reports.
People who spent more than four hours a day doing light physical activity had more than a 30 percent reduction in their risk for developing a disability, compared to those spending only three hours a day in light activity, researchers found.
"The bottom line is to stay as active as possible. Even spending time in light activity will be beneficial," said lead author Dorothy Dunlop, a professor with the Center for Healthcare Studies at Northwestern University's Feinberg School of Medicine, in Chicago.
The federal government recommends that adults get at least 2.5 hours of moderate-intensity exercise a week. Such exercise is known to reduce a person's risk of disability, Dunlop said.
But some people have health issues that prevent them from pursuing that level of exercise, which includes activities like walking briskly, water aerobics, ballroom dancing and bicycling slower than 10 miles per hour, she said. http://www.nlm.nih.gov/medlineplus/news/fullstory_145970.html
