Even minimal increases in daily physical activity-such as a five-minute brisk walk-could prevent one in ten premature deaths, according to new research. The findings underscore how small, consistent movements can yield substantial long-term health benefits.
Key findings from the research
A large-scale analysis of data from 150,000 adults across the UK, US, and Scandinavia revealed that just five minutes of moderate daily activity, like cycling or climbing stairs, could have a profound impact on longevity. The study, led by Professor Ulf Ekelund of the Norwegian School of Sport Sciences, highlights that these modest increases in movement benefit the broader population, not just individuals.
"It was surprising that very small changes in physical activity of five minutes per day have such a large impact on reducing the risk for premature mortality," Ekelund said.
Reducing sedentary behavior
The research also found that cutting daily sitting time by 30 minutes was linked to a 7% reduction in early death risk. Physical inactivity is a leading cause of chronic disease and premature mortality, making even minor reductions in sedentary habits valuable. Ekelund emphasized the importance of consistency, advising individuals to "start slow and gradually build up the amount" of activity based on personal preferences and abilities.
The power of 'exercise snacking'
Short bursts of activity, or "exercise snacking," have gained attention for their accessibility and effectiveness. These brief sessions-such as vigorous vacuuming, dancing, or taking the stairs-can be integrated into daily routines without requiring dedicated gym time. A study found that over 82% of participants continued exercise snacking, likely due to its ease of adoption.
Marie Murphy, a professor of exercise and health at Ulster University, explained that these small activity bursts stimulate metabolism more frequently. "When we stop exercising, our metabolism keeps going a little bit quicker while we recover," she noted on the BBC's Just One Thing podcast.
Practical ways to increase movement
Simple environmental prompts, like signs encouraging stair use, can nudge people toward healthier choices. Amanda Daley, a professor of behavioural medicine at Loughborough University, advocates for "snacktivity"-small, habitual changes such as parking farther from destinations or doing squats while waiting for food to cook. In a small study, participants found these micro-activities easier to sustain than longer exercise sessions.
Walking also offers significant benefits. Research cited by the BBC shows that taking 2,500-2,700 steps daily reduces cardiovascular risk by 11% compared to just 2,000 steps. Other options, like rock climbing, dance classes, or high-intensity interval training, can further improve blood sugar control, blood pressure, and body composition.
Muscle-strengthening activities
Combining aerobic exercise with muscle-strengthening activities has been shown to extend lifespans, particularly for adults in their 60s and 70s. The study reinforces that long-term health benefits do not require drastic lifestyle changes-just consistent, incremental movement.
As Nicole Logan, an assistant professor of kinesiology at the University of Rhode Island, noted, physical activity helps prevent high stress and burnout while improving muscle strength, bone density, and overall longevity.
Building sustainable habits
Experts agree that small, manageable adjustments-like opting for stairs or incorporating squats into daily tasks-can lead to meaningful health improvements over time. "We just have these unconscious ways of doing things that mean we're more likely to do it," Daley said, emphasizing the role of habit formation in sustaining activity levels.
