Researchers say modest physical activity — as little as five minutes a day — may help lower the risk of premature death, improve heart health, strengthen muscles, and reduce the long-term effects of inactivity.
The findings come from a large-scale study involving more than 150,000 adults across the UK, the US, and Scandinavia, where scientists examined the relationship between physical activity and long-term health outcomes.
According to Professor Ulf Ekelund of the Norwegian School of Sport, who led the research, the results were striking because relatively small increases in movement appeared to produce measurable population-wide health benefits.
“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,” he said.
The research found that engaging in moderate activities such as brisk walking, cycling, climbing stairs, dancing, or even energetic housework could help prevent around one in ten early deaths when adopted across the wider population.
Although experts stress that five minutes of exercise alone is not enough to maintain optimal health, they say the findings reinforce an important message: doing something is far better than doing nothing.
Adults are still encouraged to aim for the World Health Organization’s recommendation of at least 150 minutes of moderate-intensity physical activity each week. However, the latest findings suggest that people who struggle with structured workouts or gym routines can still benefit greatly from introducing small bursts of movement into their daily schedules.
The study also highlighted the dangers of prolonged sitting. Researchers found that reducing sedentary time by just 30 minutes daily was linked to a seven percent reduction in the risk of early death across the population.
Experts say consistency, rather than intensity, is often the most important factor.
“Start slow and gradually build up the amount,” Ekelund advised. “The activity should be tailored to the individual’s preferences and ability.”
The growing popularity of what researchers describe as “exercise snacking” is also helping reshape attitudes toward fitness. The approach involves short bursts of movement spread throughout the day instead of a single lengthy workout session.
Health specialists say these mini-activities can be surprisingly effective for improving cardiovascular health, muscular endurance, metabolism, and mental wellbeing.
Examples include climbing stairs quickly, doing squats while watching television, dancing during household chores, walking while making phone calls, or carrying groceries instead of driving short distances.
Research involving older adults found that combining aerobic exercises with muscle-strengthening activities reduced the risk of death and improved quality of life compared to those who remained inactive.
Professor Marie Murphy of Ulster University explained that shorter exercise sessions repeated throughout the day may provide added metabolic benefits.
“When we stop exercising, our metabolism keeps going a little bit quicker while we recover,” she said. “You still have that metabolic mill turning.”
Behavioural experts also believe that simple environmental changes can encourage healthier habits. According to studies, prompts such as signs encouraging people to use stairs instead of lifts often lead to measurable increases in physical activity.
Amanda Daley, a professor of behavioural medicine at Loughborough University, said sustainable fitness habits are often built through small, repeated actions rather than dramatic lifestyle changes.
“We just have these unconscious ways of doing things that mean that we’re more likely to do it,” she explained. “You take the stairs because that’s what you’ve learned. It’s a habit.”
Daley also encouraged what she called “snacktivity” — small opportunities for movement integrated into everyday life — such as parking farther from destinations or taking brief walking breaks during work hours.
Other studies have also challenged the belief that people must reach the traditional 10,000-step benchmark daily to gain health benefits. One study found that walking between 2,500 and 2,700 steps per day already produced noticeable reductions in cardiovascular risk compared to extremely low activity levels.
Experts say the overall message is simple: regular movement, no matter how small, can make a meaningful difference over time.
Whether through walking, dancing, cycling, stretching, climbing stairs, or quick home exercises, health professionals insist that incorporating small “exercise snacks” into daily routines may be one of the easiest and most accessible ways to improve long-term health.
