One study showed that hourly five-minute walking breaks boosted energy levels, sharpened focus, and “improved mood throughout the day and reduced feelings of fatigue in the late afternoon.” These “microbursts of activity,” as the researchers call them, were also more effective than a single thirty-minute walking break—so much so that the researchers suggest that organizations “introduce physically active breaks during the workday routine.”20 Regular short walking breaks in the workplace also increase motivation and concentration and enhance creativity.21
