Sedentary behavior can bring changes to a section of the brain that controls our memory

Prolonged sitting is often associated with physical health problems like heart disease and metabolic disorders. But a new study has found that increased sitting not only take a toll on our bodies but also affects our brain health. Sitting too much can shrink the part of the brain that controls our memory.

For the study, researchers from University of California, Los Angeles (UCLA) recruited 35 people between the ages of 45 and 75 and asked them questions about their physical activity level and the average number of hours they spent sitting per day. Then, researchers scanned the brain of each of the participant with MRI scanner, which provided a detailed look at the medial temporal lobe. It is a region in brain that is responsible for the formation of new memories. Researchers found that extended sitting was linked with thinning of the medial temporal lobe, regardless of an individual’s physical activity level.

“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.” Researchers said in a statement.

The study, however, has its limitations and shortcomings. Firstly, it is not conducted at large scale. Also, it does not prove that too much sitting causes thinner brain structures, but instead that more hours spent sitting has a connection with thinner brain regions.

In the future, researchers are aiming to find out whether sitting actually causes brain thinning and what role gender, race and weight might play in brain health in relation to sitting.
