A new study has found that walking for just five minutes every hour is enough to offset the health harms caused by prolonged sitting. The research, published in the British Journal of Sports Medicine, involved 11,484 participants and tested the effects of brief movement breaks at different intervals.
Study Details and Methodology
Adults in high-income countries like the UK now spend 11–12 hours per day sedentary, which corresponds to over three-quarters of the waking day. Researchers from the US, including experts from Columbia University Medical Centre, noted that excessive sedentariness increases the risk of chronic conditions, poorer mental health, and mortality, and poses a substantial economic burden on healthcare systems.
Participants followed their usual routine for seven days, then chose five-minute walking breaks every 30 minutes, every 60 minutes, or every two hours for 14 consecutive days. Over the 21 days, they filled in questionnaires on fatigue, mood, and work performance. A random sample of 1,200 full-time employees also received five text messages daily at 9am, noon, 3pm, 6pm, and 9pm to assess the immediate impact of movement breaks.
Key Findings on Break Frequency and Effectiveness
Analysis revealed that all three break intervals were perceived as doable, acceptable, and appropriate, although fewer breaks were seen as more obtainable. People were more likely to report good mood from taking breaks, with every 30-minute break leading to the highest gains, while fatigue and low mood scores fell across all break times.
Overall, taking a five-minute break every hour offered the best balance between what people thought was achievable day-to-day and effectiveness for health. The study also found that taking short breaks did not affect work performance, countering concerns that movement breaks might disrupt productivity.
Expert Commentary and Public Health Implications
Emily McGrath, senior cardiac nurse at the British Heart Foundation, said: "This study looked at how movement breaks affect mood and fatigue, but we also know that sitting for long periods increases the risk of heart and circulatory disease and early death. Taking regular 'energy snacks', like a five‑minute walk each hour, can boost mood and support heart health."
However, she noted that the study relied on self-reported data and was short-term, so longer research is needed to confirm its impact on heart health. The researchers concluded: "This large-scale study demonstrates that movement breaks are implementable and effective, supporting their potential as a public health strategy."
Regular movement may offset the harms of prolonged sitting by improving blood flow and reactivating metabolic processes linked to how the body deals with fats and glucose, the team explained.
