Think Five Minutes Won’t Make a Difference?

You skip the gym because you've only got ten minutes, or tell yourself an earlier night doesn't count unless you gain a full extra hour. Two large studies published this year suggest that logic may be backwards. When it comes to long-term health, small, repeatable improvements may still matter.

What New Research Says About Sleep, Exercise, Diet and Lifespan

A UK Biobank study of 59,078 adults examined how combinations of sleep, physical activity and diet were associated with lifespan and healthspan. Among people with less healthy baseline habits, the researchers estimated that a combined improvement of around five additional minutes of sleep, two additional minutes of moderate-to-vigorous physical activity and a small improvement in diet, roughly equivalent to half a serving of vegetables, was associated with approximately one additional year of life expectancy (Koemel et al., 2026).

How Bigger Improvements Linked to Nine Extra Years of Healthspan

The associations became larger as behaviours improved. Around seven to eight hours of sleep, more than 40 minutes of moderate-to-vigorous physical activity per day and a higher-quality diet were associated with more than nine additional years of lifespan and healthspan compared with the least healthy combination.

A separate individual participant data meta-analysis examined physical activity, sedentary behaviour and mortality. The primary analysis included more than 40,000 adults across prospective cohorts, with UK Biobank data from a further 94,719 participants analysed separately.

Can Five Extra Minutes of Activity a Day Reduce Deaths?

The researchers estimated that adding just five minutes of moderate-to-vigorous physical activity per day among the least active people could potentially avert around 6% of deaths. Across the broader population, excluding the most active, the estimate was around 10%. Reducing sedentary time by 30 minutes per day was associated with corresponding estimates of approximately 3% and 7% (Ekelund et al., 2026).

These are important findings, but they need to be interpreted carefully. Neither study was a randomised intervention showing that adding five minutes of movement or sleep will directly extend an individual's life by a specific amount. They are observational analyses, so the findings show associations and modelled population-level estimates rather than guaranteed personal effects.

Even so, the broadly consistent pattern across large-scale prospective analyses strengthens the case that relatively small differences in everyday behaviours may still be meaningful.

Why Small Healthy Habits Still Count

The practical message isn't that five minutes is some biological magic number. It's that improving your health doesn't necessarily require starting with the optimal version of every behaviour.

Large lifestyle targets can be difficult to integrate into an already busy life. Smaller changes may be easier to implement, repeat and build upon. Importantly, the Koemel study doesn't show that small goals are psychologically superior to large ones. What it does suggest is that meaningful associations with lifespan and healthspan are detectable well before someone reaches an "optimal" lifestyle.

That matters if your current benchmark for success is a 45-minute workout, eight perfect hours of sleep or an immaculate diet.

The alternative isn't doing nothing. It may simply be doing slightly better, consistently.

Turning the evidence into action

1. Start with the easiest lever. You don't need to optimise sleep, exercise and nutrition simultaneously. Begin with the change you can implement most reliably, then build from there. The Koemel study suggests that small improvements across several behaviours may eventually add up.

2. Make the first target deliberately achievable. Go to bed five minutes earlier. Add a five-minute brisk walk after lunch. Put an extra portion of vegetables on your plate. The goal isn't to stop at five minutes forever. It's to lower the barrier to starting.

3. Pay attention to sitting as well as exercise. The Ekelund analysis examined reducing sedentary time separately from increasing moderate-to-vigorous activity. A structured workout doesn't necessarily cancel out an otherwise highly sedentary day. Look for opportunities to interrupt prolonged periods of sitting with movement.

4. Think consistency rather than individual days. These studies describe habitual behaviour patterns rather than the effect of one particularly healthy day. A simple daily tick for sleep, movement or nutrition may therefore tell you more about the behaviour you're building than obsessing over individual workouts or calorie counts.

5. Build towards better, not perfect. If 40-plus minutes of daily activity, sufficient sleep and a high-quality diet are realistic for you, the evidence suggests the associations become substantially stronger. But you don't have to start there.

The Bottom Line on Small Changes and Long-Term Health

The useful message from this research isn't that five minutes of exercise will magically add years to your life.

It's that the gap between doing nothing and doing something may be more important than we think.

And once something becomes normal, you can build from there.
