Sitting is bad for the brain

Too much sitting is linked to thinning of a brain area (medial temporal lobe), where new memories are formed.

The research has been conducted by UCLA researchers and is of middle aged and older adults.

Main titles

Physical activity is unlikely to reverse the harmful effects of extended sedentary lifestyle.
The effect is relational and not causal. It has not been proved that a sedentary lifestyle leads to thinning of brain areas, however more hours spent sitting is linked to thinning of brain areas.

Further research is planned to decide whether more hours spent sitting causes thinning of certain brain regions.
According to the researchers, a thinning of the MTL is a predeccesor of dementia and cognitive decline in middle age adults and older.
