Standing desks have grown in popularity as an alternative to the sedentary office lifestyle that recent studies have shown is slowly but steadily killing us. Standing in intervals boosts metabolic metrics like calorie burn and blood flow–perhaps not significantly, and not as a replacement for exercise, but enough to make a small dent in the tyranny of the office chair. Now a new study suggests that standing desks may also provide a brain boost by enhancing cognitive skills like focus and memory.
