Study Finds 5‑Minute Hourly Walks Reduce Risks of Prolonged Sitting

Researchers analyzed data from more than 19,000 adults in the United States who participated in a two‑week trial of short‑duration activity breaks. Participants who stood up and walked for five minutes each hour reported less fatigue, better mood, and higher work performance, while also showing reduced markers linked to cardiovascular disease and early mortality. The study, published in the *British Journal of Sports Medicine*, compared walking breaks every 30 minutes, every hour, and every two hours, concluding that the one‑hour interval offered the best balance between feasibility and health benefit.

A similar trial involving over 11,500 participants reported comparable findings, noting that frequent “active snack” breaks can counteract the metabolic and circulatory harms of prolonged sedentary behavior. Experts such as senior cardiac nurse Emily McGrath highlighted that brief, regular movement bouts help maintain blood flow and metabolic processes, lowering the risk of heart disease and premature death. The research adds to growing evidence that modest, regular activity – as little as five minutes per hour – can substantially improve physical and mental health for office‑based workers and others who sit for most of the day.
