Sitting is bad for your brain -- not just your metabolism or heart

On the other hand, a separate study revealed that replacing six hours of sitting each day with standing may help prevent weight gain and support weight loss.

Sitting too much could raise the risk of memory related chronic ailments like Dementia and Alzheimer's disease, according to a freshly published by researchers at University of California Los Angeles (UCLA).

Prabha Siddarth, a biostatistician at the Semel Institute for Neuroscience and Human Behavior at UCLA, is the study's first author. Scientists directed high-determination MRI of study subjects to check the thickness of their media worldly flaps.

A thinned MTL is typically a predecessor for dementia and marked cognitive declines in middle-aged to older people, the study said.

The study doesn't prove that sitting causes damage to the brain but does highlight a connection between sitting more often and having thinner structures in the MTL. Rather than sitting on work area for long stretch, moving around with little breaks is viewed as valuable in decreasing the dangers related with sitting occupations.

The specialists found that inactive conduct is a noteworthy indicator of diminishing of the MTL and that physical action, even at abnormal states, is inadequate to counterbalance the unsafe impacts of sitting for expanded periods. Future research project will aim to check the role gender, race, and weight might play in the negative effects of long periods of sitting each day. They added, however, that more extensive research is still needed, as only a few subjects were involved in the study.

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.

Scientists at the University of California recruited 35 people aged between 45 and 65 and questioned them about how many hours per day they spent sitting down over the previous week.

The researchers discovered that the subjects who were sitting too much daily, defined as three to seven hours per day, had significant thinning of their medial temporal lobe, the part of the brain where new memories are formed. The participants said they spent from 3 to 7 hours in a chair per day, on average. 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.
