As many Brits embark on their 2026 health resolutions, a landmark new study offers a remarkably simple and free strategy to improve longevity: taking a short daily walk.
The Power of Small, Realistic Changes
Research led by scientists at the Norwegian School of Sports Sciences, published in The Lancet, indicates that making 'small and realistic' increases in moderate-to-vigorous physical activity (MVPA) can prevent a meaningful number of premature deaths. MVPA refers to exercise that significantly raises your heart rate, such as brisk walking, cycling, or dancing.
How Much Walking Makes a Difference?
The study's estimates provide clear, actionable guidance. For the general population, walking for just five minutes per day could lower the risk of early death (before age 75) by 10%. Doubling that to a 10-minute daily walk could reduce the risk by 15%.
However, the impact is even more pronounced for the 'least active' individuals. For this group, a five-minute walk was associated with a 6% risk reduction, highlighting that any movement is beneficial, especially when starting from a sedentary baseline.
Beyond Walking: The Dangers of Sitting
The research, which analysed data from 135,000 people in the UK, Norway, the US, and Sweden over eight years, also examined sedentary behaviour. It found that reducing daily sitting time by 30 minutes could help prevent approximately 4.5% of deaths.
For those unable to go outside, the scientists noted that simply getting up and moving around the home—doing housework, for instance—can also contribute positively.
'Offers Hope' and a Call for Further Research
Dr Brendon Stubbs of King's College London told The Times that the study 'offers hope' to those who are not regularly active. 'This finding serves as an inspiring public health message: even small daily tweaks to activity levels can make a meaningful difference,' he said, suggesting quick walks or taking extra stairs.
He also cautioned that the study was observational, meaning it cannot definitively prove cause and effect. Randomised controlled trials would be needed to confirm that these specific lifestyle changes directly reduce mortality rates.
The findings add to a growing body of evidence on accessible health improvements. This follows recent advice from longevity expert Dr Mohammed Enayat, who emphasised the importance of regulating circadian rhythms and managing stress for long-term health, alongside regular NHS check-ups.
