Columbia Study Shows Hourly 5‑Minute Walks Boost Office Productivity

A Columbia University research project, published in the British Journal of Sports Medicine, tracked more than 11,000 U.S. office workers to evaluate how brief walking breaks affect wellbeing and performance. Participants were assigned to take five‑minute walks either every 30 minutes, every hour, or every two hours during their workday. The hourly five‑minute walks produced the greatest overall gains, raising mood, reducing fatigue, and improving attention and productivity without overly disrupting workflow. Walks every 30 minutes helped mood but fragmented work, while walks every two hours offered limited benefit.

Study lead author Keith Diaz highlighted that prolonged sitting raises risks of obesity, heart disease and type‑2 diabetes, and that short, regular movement is a low‑cost way to counteract these effects. External experts, such as Emily McGrath of the British Heart Foundation, praised the findings but cautioned that the data rely on short‑term self‑reports and longer‑term health impacts remain to be confirmed.
