Studies find that even mild activity is better than no activity when it comes to preventing Alzheimer’s.

For those whom may be too frail for swimming or gym activities it appears as though light housework and gardening can be effective ways to keep active and avoid the disease.

The study, which was published this week in the journal Neurology, included 716 dementia-free men and women in their 70s and 80s. Compared with the most active people, those with the lowest levels of overall physical activity had more than double the risk of going on to develop Alzheimer’s. Greater physical activity was also associated with a slower rate of aging-related memory and cognitive decline.

“This suggests that people in their 80s who can’t participate in formal exercise still get a benefit by leading a more active lifestyle,” says lead author Dr. Aron S. Buchman, associate professor of neurological sciences at Rush University Medical Center, in Chicago. “You don’t have to get a membership in the local YMCA. If you walk up some more steps, stand up and do the dishes more, you stand to benefit because it’s incremental and adds up over the course of a full day.”

The key is to keep moving!
