The research on stand up desks so far is inconclusive. The benefits may be more myth than reality. A systematic review by Cochrane researchers looked at 26 studies with 2,174 people. They found that sit-stand desks reduced sitting by between 30 minutes and two hours a day.
While this sounds impressive, the researchers say the studies mostly did not deliver the up-to-four-hours of standing that experts recommend. Standing desks were also not found to have much benefit in weight reduction – if an average-sized man and woman spent half of their eight-hour working day standing, they would spend an additional 20 kilocalories and 12 kilocalories each.
This, point out the researchers, is not enough to prevent obesity or type 2 diabetes. Prolonged standing may also be difficult for people with low back pain.
