In a nutshell
- đ¤ New global study finds focusing on sleep may be more beneficial than exercise for everyday health; only 1 in 8 meet both 7â9 hours sleep and 8,000 steps (published in Communications Medicine).
- đ Analysis of 70,000 participants over 3.5 years using wearables shows many achieve either sleep or activityâbut rarely both; reliance on trackers is a limitation skewed toward wealthier regions.
- â ď¸ Nearly 17% averaged fewer than 7 hours of sleep and under 5,000 steps, a âsedentaryâ pattern linked to higher risks of chronic disease, weight gain, and mental health challenges.
- đ Sleeping about 6â7 hours was associated with the highest nextâday step counts; when time is tight, researchers advise prioritising sleep to fuel energy and movement.
- đ ď¸ Practical steps: reduce evening screen time, keep a consistent bedtime, and create a calm sleep environmentâguidance echoed by Josh Fitton and Danny Eckert of Flinders University.
Getting enough sleep may be the key to staying healthy. Thatâs the compelling message from a new global analysis indicating that sleep may matter even more than exercise for dayâtoâday wellbeing. Drawing on data from wearable devices, researchers found that while many people manage either decent rest or regular movement, far fewer hit both benchmarks consistently. Only around one in eight did. The study, published in Communications Medicine, suggests a simple pivot: if time is tight, start with sleep. Build energy first, then move more. Itâs a pragmatic reframing for busy lives. And itâs grounded in evidence tracked across years, not a single snapshot.
Sleep May Trump Exercise for Health
Around the world, the widely promoted targets are familiar: seven to nine hours of nightly sleep and roughly 8,000 steps a day. Yet the studyâs authors argue these goals are often chased in isolation, and everyday routines make balancing both hard. Lead author Josh Fitton of Flinders University is blunt: âOnly a tiny fraction of people can achieve both recommended sleep and activity levels every day.â His point is not defeatist. Itâs strategic. When people inevitably must prioritise, the data suggest that sleep comes first.
That ordering matters. Better rest appears to unlock motivation, mood, and the physical capacity to move more the next day. Senior author Danny Eckert puts it simply: âPrioritising sleep could be the most effective way to boost your energy, motivation, and capacity for movement.â The implication is powerful for public health messaging. Instead of pushing steps alone, promote sleep as the foundation. Then stack activity on top. Itâs an approach designed for real life, not for ideal conditions that few can maintain every day.
What the Global Tracker Data Reveals
The research analysed aggregate sleep and activity tracker data from more than 70,000 participants over 3.5 years. That scale offers a rare lens on daily behaviour, not just selfâreported habits. The topline result is striking: only about 13 per cent routinely achieved both sleep and activity targets. At the other end, nearly 17 per cent averaged fewer than seven hoursâ sleep and under 5,000 steps a day. The study categorised them as âsedentary,â a pattern linked to heightened risks of chronic disease, weight gain, and mental health challenges. Itâs a common pattern, not a moral failing. It is also changeable.
There are caveats. Personal trackers skew toward higherâincome users and regions, which the authors acknowledge as a limitation. Still, the dayâtoâday patterning is robust: sleep and movement ebb and flow together. Below is a snapshot of the key findings.
| Metric | Finding |
|---|---|
| Met both sleep and activity targets | ~13% |
| Short sleep + low steps (âsedentaryâ) | ~17% |
| Recommended sleep | 7â9 hours |
| Daily activity benchmark | 8,000 steps |
| Sleep linked to most nextâday steps | 6â7 hours |
How to Prioritise Sleep Without Ditching Movement
The study highlights a useful lever: sleeping roughly six to seven hours was associated with the highest nextâday step counts. That doesnât replace the longâterm recommendation of seven to nine hours, but it shows how sleep quality and timing can boost momentum. If you are pressed for time, the researchers suggest choosing rest first. Then plan your activity when energy peaks. Small shifts compound. Trim lateânight scrolling. Guard a consistent bedtime. Create a calm, cool, dark room. Those simple steps, the authors note, can drive meaningful gains.
Crucially, this isnât a zeroâsum game. Building movement into routines reduces pressure to carve out big blocks. Walk while calling a friend. Take the stairs one floor. Add a short, brisk loop after lunch. But anchor the change in sleep. As Eckert emphasises, rest fuels the motivation and capacity for movement. For many, thatâs the unlock. Start by stabilising nights. Then the steps become easier, the rhythm more sustainable, and the health benefits more attainable for those who rarely hit every target at once.
Public health advice can feel overwhelming: sleep more, move more, do it daily. This study reframes the task. Build a solid base with sleep, then layer in activity. Itâs kinder to busy schedules and truer to human behaviour. The numbers are soberingâonly one in eight hit both goalsâbut they point to an achievable sequence. Begin where gains ripple outward. Prioritise rest, protect it, and let energy drive movement. If you tried one change this week, which sleep habit would you adjust first to make tomorrowâs steps feel easier?
