The next small workplace habit may not be a new app, a standing desk, or a stricter calendar. It may be a five-minute walk once an hour, slipped between emails, video calls, and the long quiet stretch of sitting that defines so many office days.
A new study suggests those short “movement snacks” can improve mood, lower fatigue, and leave work performance largely intact. The idea is simple enough for a busy day: work for about 55 minutes, then get up and move for five.
Sitting is the starting point
Being sedentary means spending long stretches awake but barely moving, usually sitting or reclining. That sounds harmless, especially when work feels mentally demanding, but the body still notices.
According to the researchers, adults in high-income countries spend an average of 11 to 12 waking hours a day sedentary. That level of inactivity has been linked with higher risks of long-term health problems and death.
What researchers tested
The study was led by Keith Diaz, a certified exercise physiologist and professor of behavioral medicine at Columbia University Medical Center. The researchers drew on 19,342 adults who joined National Public Radio’s interactive “Body Electric Challenge” in the United States.
Of that group, 11,484 people began a two-week walking-break program after one week of their usual routine. They chose five-minute breaks every 30 minutes, every 60 minutes, or every 120 minutes, then reported fatigue, mood, and work performance through surveys.
So what is a movement snack? Basically, it is a small dose of activity taken during the day, not a workout you need to plan around. A walk down the hallway, a loop around the block, or pacing during a phone call can count.
Why one hour stood out
Walking every 30 minutes produced the strongest improvements in fatigue and mood, but it was harder for people to keep up–anyone who has a packed calendar can see the problem. A bre ak every half-hour may sound healthy, but it can collide with meetings, deadlines, and the normal rhythm of office life.
Walking every two hours was easier to fit in, but it brought weaker benefits. The hourly option landed in the middle, giving many workers a realistic routine that still crossed the study’s threshold for meaningful improvement in fatigue and good mood.
Diaz put it plainly in comments shared with BBC News: “The good news is that a walk break every hour for five minutes is enough to improve mood and lower fatigue, and people found this realistic and attainable,” he said.
The productivity worry
Many workers hesitate to stand up because they worry about how it looks. Will a manager think they are slacking? Will coworkers wonder why they keep leaving their desk?
The study addressed that concern directly. The researchers reported that movement breaks did not undermine perceived work performance, and work engagement and performance showed small favorable changes on average.
Diaz said the finding may feel counterintuitive, but it fits what scientists know about attention and energy. “Although it may seem counterintuitive, movement breaks can improve work performance,” he said. “They can boost executive functions, attention, and memory. They also help people feel more relaxed and energized.”
How to use it at work
At the end of the day, this is less about exercise culture and more about making a normal workday less draining. A five-minute walk does not require special clothes, a gym membership, or a heroic lunch-hour run.
It may also be easier when the workplace makes room for it. Walking meetings, phone calls taken on foot, or a shared reminder to move each hour can turn the habit into something ordinary rather than awkward.
Emily McGrath, a senior cardiac nurse at the British Heart Foundation, welcomed the research because adding simple physical activity can support general health.
She also warned that the study was short and based on self-reported data, so longer research is needed to confirm its impact on heart health.
A useful finding with limits
The study was carried out in real-world conditions, which makes it more practical than a tightly controlled lab test. That is important because a habit only helps if people can actually fit it into their day.
Still, the results should not be treated as a cure-all. The researchers noted that the outcomes were subjective, participants were mostly white, female, and highly educated, and the study lasted only two weeks.
Even with those limits, the takeaway is refreshingly down to earth. If your afternoon usually turns into heavy eyelids, stiff legs, and another cup of coffee, a five-minute walk may be worth trying.
The official study has been published in the British Journal of Sports Medicine.
