Standing desks have been promoted as a healthy alternative for office workers who don't want to stay seated in front of a computer all day. But a new study suggests that standing desks may not be so good for us after all. A research team, led by scientists at the University of Sydney, has found that standing for over two hours a day may increase the risk of developing circulatory diseases that can prevent the proper flow of blood in the body. The researchers looked at data from over 83,000 adults in the UK who were not suffering from heart disease at the start of the study. For seven days, the participants wore a device on their wrists that recorded the time they spent sitting or standing each day. After collecting this data, the researchers recorded any heart disease or circulatory health problems the participants experienced over the following seven years. The research team calculated that after standing for two hours, every extra 30 minutes someone stands increases their risk of having a circulatory disease by 11%. And although standing was not associated with an increased risk of health problems like heart disease or stroke, standing does not reduce the risk of developing such health problems either. Speaking to The Guardian, Matthew Ahmadi, one of the authors of the study, said the key point of the study's findings is that standing instead of sitting doesn't provide any health advantage, and could increase health risks for some people. Emmanuel Stamatakis, one of the other authors of the study, told The Guardian that moving around during the day and getting regular exercise are better ways to reduce the risk of heart disease. "Take regular breaks, walk around, go for a walking meeting, use the stairs, take regular breaks when driving long distances, or use that lunch hour to get away from the desk and do some movement," he said.
