Sitting is Bad for Your Brain, Not Just Your Heart or Metabolism

It’s been a couple of years now since I first learned the dangers of prolonged sitting. Someone even called ‘sitting the new smoking.‘ I thought that might have been excessive – might have been. However, this new information from UCLA researchers certainly adds resonance to the problem for seniors.

Sitting too much is linked to changes in a section of the brain that is critical for memory, according to a preliminary study by UCLA researchers of middle-aged and older adults.

Studies show that too much sitting, like smoking, increases the risk of heart disease, diabetes and premature death. Researchers at UCLA wanted to see how sedentary behavior influences brain health, especially regions of the brain that are critical to memory formation.

METHOD

UCLA researchers recruited 35 people ages 45 to 75 and asked about their physical activity levels and the average number of hours per day they spent sitting over the previous week. Each person had a high-resolution MRI scan, which provides a detailed look at the medial temporal lobe, or MTL, a brain region involved in the formation of new memories.

The researchers found that sedentary behavior is a significant predictor of thinning of the MTL and that physical activity, even at high levels, is insufficient to offset the harmful effects of sitting for extended periods.

This study does not prove that too much sitting causes thinner brain structures, but instead that more hours spent sitting are associated with thinner regions, researchers said. In addition, the researchers focused on the hours spent sitting, but did not ask participants if they took breaks during this time.

The researchers next hope to follow a group of people for a longer duration to determine if sitting causes the thinning and what role gender, race, and weight might play in brain health related to sitting.

IMPACT

MTL thinning can be a precursor to cognitive decline and dementia in middle-aged and older adults. Reducing sedentary behavior may be a possible target for interventions designed to improve brain health in people at risk for Alzheimer’s disease, researchers said.

Further on the dangers of sitting too long

About a year ago I began to learn the dangers of prolonged sitting. I posted a Page on it – Do you know the dangers of too much sitting?  Which you can check out at your leisure. The following analysis comes from Texas A & M University.

It’s a popular catchphrase: “Sitting is the new smoking.” A phrase that is often attributed to James A. Levine, MD, PhD, of the Mayo Clinic, but even he seems to have pulled back from that characterization a little, now simply saying that sitting for long periods of time is linked to conditions like obesity and metabolic syndrome.

And it’s the obesity that really leads to problems, according to Mark Benden, PhD, CPE, associate professor in the Department of Environmental and Occupational Health and director of the Ergonomics Center at the Texas A&M School of Public Health. He studies the use of sit-stand desks to promote physical activity. “The better metaphor might be obesity is the new smoking,” Benden said. “That’s a little closer from a cause-and-effect standpoint, in terms of the number of people dying from these preventable causes each year.” Continue reading

Can too much sitting erase exercise benefits?

I have written about the dangers of prolonged sitting previously. You can check out my Page – Do you know the dangers of too much sitting?  for further information on it.

White matter is brain tissue containing nerve fibers responsible for brain communication. As we age, nerve fiber activity declines and disrupts brain function. But a new study suggests that among older adults, the structural integrity of white matter is not only dependent on levels of physical activity, but also on the amount of remaining time spent sedentary, according to Medical News Today.

Lead researcher Agnieszka Burzynska, a postdoctoral researcher at the University of Illinois, and her team publish their findings in the journal PLOS ONE.

Past studies have associated physical activity among older adults with reduced cognitive decline. In 2012, research from the University of Scotland in the UK found that seniors who had high levels of physical activity had fewer problems with memory and thinking skills, while a 2013 study claimed exercise is beneficial for the cognitive functioning of dementia patients.

Is your office bad for your health?

Okay, nobody is saying that working in an office is as dangerous as doing construction or working in a mine, but health hazards exist in offices, too. It’s easy to grow complacent about it.

Desk jobs can pose dangers to your health. Rush family medicine physician Gabriela Baeza, MD, recently discussed some of the most common hazards — and how to avoid them.

Chairs
A growing body of research suggests that simply sitting too much can endanger your health — regardless of whether you get the recommended 30 minutes of exercise at least five days a week.

Researchers have found that too much sitting might make you less sensitive to insulin (a hormone that helps your body process and use energy from food). It also might lead to higher levels of triglycerides, or fats, in your blood. Such effects could, in turn, make you more likely to develop diabetes, heart disease or even cancer. Continue reading

Can exercise erase damage from excessive sitting? – Harvard

I confess that only last year I was ignorant of the fact that sitting for a prolonged period was very hazardous to your health. Since then, I have erased much of my ignorance with a number of posts. You can check them out on my Page – Do you know the dangers of too much sitting? So I was gratified to read the latest info on sitting from the Harvard Medical School.

“Can an hour of brisk walking counteract the downsides of sitting for most of the day? Maybe, according to a study published online July 27, 2016, by The Lancet.

Do You Know the Dangers of Too Much Sitting?

I must confess that only a few months ago I was amazed to learn that the simple act of sitting can be damaging to my health. Okay, you have to be sitting for a while, but not all day. This is something you need to know more about. One observer called sitting the new smoking and I actually used that as a header on a blog post. You can decide for yourself whether that is inflammatory or not. When the staid New York Times gets into the discussion, I think it’s time to find out more.

For the record, it's not the chair that's evil, it's your sitting too long in it. Read some of the hints on this page ...

Sitting is the New Smoking

This is my second post on the damage of sitting too much today. As regular readers know I feel strongly about the damage smoking does to the body and this very extensive write up of how sitting too much hurts you covers even more ground than I have in previous posts.

Auxiliary Memory

By James Wallace Harris, Tuesday, October 7, 2014

The new catch phrase I’m hearing is “Sitting is the New Smoking.” This statement conveys so much. It triggers memories about my dad, who died when I was 18, and he was 49. He was a smoker, and survived two heart attacks and a stroke before he died on his third heart attack. I always wondered how long he would have lived if he had never smoked. It’s a shame he didn’t learn that smoking was bad when he was growing up, but that knowledge just wasn’t common back then. What future common knowledge are we missing out on now? Is sitting really the new smoking?

I have to wonder if my life would have been different if I had known sitting was so bad. I’ve had back problems for years, and at the moment I’m having neck problems, with a pinched…
