Adults aged 60 and older who sit for long periods watching TV or other such passive, sedentary behaviors may be at increased risk of developing dementia.
Their study showed the risk is lower for those who are active while sitting, such as when they read or use computers.
It also revealed that the link between sedentary behavior and dementia risk persisted even among participants who were physically active.
The results remained the same even after the scientists accounted for levels of physical activity. Even in individuals who are highly physically active, time spent watching TV was associated with increased risk of dementia, and leisure time spent using a computer was associated with a reduced risk of developing dementia.
"Although we know that physical activity is good for our brain health, many of us think that if we are just more physically active during the day, we can counter the negative effects of time spent sitting," said study author Gene Alexander, professor of psychology at the Evelyn F. McKnight Brain Institute at the University of Arizona.
"Our findings suggest that the brain impacts of sitting during our leisure activities are really separate from how physically active we are," said Alexander, "and that being more mentally active, like when using computers, may be a key way to help counter the increased risk of dementia related to more passive sedentary behaviors, like watching TV."
Knowing how sedentary activities impact human health could lead to some improvements.
"What we do while we're sitting matters," Raichlen added. "This knowledge is critical when it comes to designing targeted public health interventions aimed at reducing the risk of neurodegenerative disease from sedentary activities through positive behavior change."

She better watch out if she’s doing that, and her husband comes into the room and starts rehearsing his scenes.
brilliant
You can start over again when you no longer need glasses due to cataract surgery!
My wife says that now, but I don’t think she means the TV.
I know the feeling.
I have about 60 years worth of Nat Geo magazines.
Do they count??
Do you have the one of the polar bear family in a blizzard?
Instead of PSAs, maybe every commercial break should have an algebra problem that rewards you with popcorn if you solve it before the program resumes.
Try having goats instead!
It’s intimidating you say? LOL
LOL! My mom has a closet full of old Nat Geos and she thinks they’re valuable. We can’t even pay someone to take them. But she insists.
I just keep mine to show off.
(When I was young, I thought only doctors and dentists could receive those magazines.)
Hubby makes fun of me ‘cause I keep my Excel for Windows 95 book in my bookcase. It’s old, but I have referred to it in a pinch - although not so much since I retired. (I still use MS Office 2003.)
Computer books have been replaced by craft and quilting books.
