Too Much Sitting Is Bad For Your Memory, Study Says

The conclusions of this preliminary study are that, although a sedentary lifestyle has an effect on the brain that can lead to Alzheimer's disease, physical activity was also associated with a smaller decrease in medial temporal lobe thickness.

Prolonged sitting can diminish part of your brain responsible for storing memories, according to a new study.

"Thus, the finding that more sedentary time is associated with less thickness in MTL is clinically relevant", the authors wrote, adding that this behavior may be "a possible target for interventions created to improve brain health" for adults who were middle-aged and older adults. For majority of people in office jobs, long sitting hours has become a norm.

Other studies have shown that too much sitting, just like smoking, increases the risk of heart disease, diabetes and premature death.

The study authors concluded that rather than sitting at the desk for long stretch, moving around and reducing sedentary behaviour may be a possible target for interventions created to improve brain health in people.

This is because of his impeccable communication skills which helped him unite modern-day Norway, Germany, Sweden and Denmark. They have found almost 600 silver coins, more than 100 of which come from King Bluetooth's era.

For the study, 35 adults (i.e. 25 women and 10 men) who were middle-aged or older were recruited. With every hour of sitting daily, there was an obvious drop in brain thickness. Ranging between 45 and 75 years of age, the participants answered questions about their levels of physical activity and how much time they spent sitting over the previous week.

Health experts have earlier suggested people with long hours of office job, should take breaks in between. The researchers noted that sedentary behaviour is a significant predictor of thinning of the MTL and that physical activity, even at normal states, is inadequate to ward off the harmful effects of sitting for extended periods. Using a high-resolution MRI scan, the scientists got a detailed look at the medial temporal lobe of each participant and identified relationships among this region's thickness, the participants' physical activity levels and their sitting behavior, according to the study.

The participants reported that they spent from 3 to 7 hours, on average, sitting per day.

The study was supported by grants from various funders including the National Institutes of Health, the U.S. Department of Energy and the McLoughlin Cognitive Health Gift Fund.
