A new study finds daily physical activity helps staving off Alzheimer's disease even in adults over 80 years old, CBS News reported.

The findings, published in the journal Neurology, said even activities like cooking and cleaning are beneficial. It's not necessary to break a sweat.

"Our study shows that physical activity, which is an easily modifiable risk factor, is associated with cognitive decline and Alzheimer's disease," wrote Dr. Aron S. Buchman, associate professor of neurological sciences at Rush University Medical Center in Chicago, the study's author.

"This has important public health consequences," he said.
