Take a Five-Minute Walk: How Short Breaks During Prolonged Sitting Can Boost Mood and Reduce Fatigue
A study published in the British Journal of Sports Medicine examined the effects of taking short walking breaks during periods of prolonged sitting. The research, which analyzed data from participants in a US nationwide challenge, found that five-minute walking breaks taken at intervals of 30, 60, or 120 minutes were associated with improved mood and reduced fatigue without negatively affecting work performance.

Study Methodology
The study involved two participant groups. A primary analysis included 11,484 adults who participated in the 'Body Electric Challenge' organized by NPR. A subsequent analysis included data from 19,342 adults from the same challenge.
Participants followed their usual routines for seven days, then selected and followed a schedule of five-minute walking breaks at one of three frequencies for 14 days.
- Assessment Tools: Participants completed questionnaires measuring fatigue, mood, and work performance over a 21-day period. A random sample of 1,200 full-time employees also received text messages five times daily to assess immediate impacts.
- Break Intervals: The three frequencies tested were breaks every 30 minutes, every 60 minutes, and every 120 minutes.
- Participant Demographics: Researchers noted that the participant group was predominantly White, female, and highly educated.
Key Findings
All three break frequencies were rated as feasible, acceptable, and appropriate by participants.
The 60-minute interval was the most commonly selected, chosen by 47% of participants. This schedule was reported to offer the best balance between practical implementation and health benefits.
- Mood and Fatigue: The 30-minute break frequency produced the most significant improvements in mood and the greatest reductions in fatigue. The 60-minute and 120-minute intervals also showed improvements, though to a lesser degree.
- Feasibility: The 120-minute break frequency showed the highest implementation potential but was the least effective for improving mood and fatigue. Participants reported that fewer breaks were more achievable.
- Work Performance: The study found that movement breaks did not negatively affect work performance. Small favorable changes, ranging from 1% to 7%, were observed across all break schedules.
- Clinical Significance: Improvements in fatigue and positive mood for the 30-minute and 60-minute frequencies exceeded thresholds considered to be minimally important differences.
Background and Context
Excessive sedentary behavior has been linked to an increased risk of chronic conditions, poorer mental health, and higher mortality rates. According to researchers, adults in high-income countries spend 11 to 12 hours per day sedentary. The study suggests that regular movement breaks may improve blood flow and metabolic processes related to fat and glucose regulation.
Sitting for long periods increases the risk of heart and circulatory disease and early death.
Study Limitations
Researchers identified several limitations in the study. These included the use of subjective self-reported assessments, a participant group that was not demographically representative of the general population, and the short duration of the study.
Despite these limitations, the authors concluded that the findings support movement breaks as a potential public health strategy.
