We know too much sitting is bad for our waists — but is it bad for our brains, too?

In many aspects of life where we need to use our brain power, we also tend to sit down: at school, at work, sitting exams or concentrating on a crossword.

In a new paper, we explore how prolonged sitting may affect the brain's fuel supply and have a negative impact on brain health.

Prof Alan Hedge, a leading researcher in the area, suggests a good pattern of sitting/ standing/moving is breaking time into 30 minute blocks and sitting for 20, standing for 8 and moving for 2.
