Couch potatoes have a higher risk of developing dementia in old age, a new study reports.
Seniors who get little to no exercise have a 50 percent greater risk of dementia compared with those who regularly take part in moderate or heavy amounts of physical activity, the researchers found.
Moderate physical activity can include walking briskly, bicycling slower than 10 miles an hour, ballroom dancing or gardening, according to the U.S. Centers for Disease Control and Prevention.
“It doesn’t require intensive physical activity to decrease risk of dementia,” said senior researcher Dr. Zaldy Tan. He is medical director of the Alzheimer’s and Dementia Care Program at University of California, Los Angeles. “Even moderate amounts are fine.”
