Does exercise help you sleep? What 10 minutes a day can do for deep sleep

A week of busy days with no time to move, and somehow you sleep worse, not better. That pattern has some research behind it.

A study from The University of Texas at Austin, shared widely again this week, found that people who were active on more days of the week spent more time in deep, restorative sleep. As little as 10 minutes a day of activity that gets you breathing harder was linked with better sleep, and even walking and standing breaks were tied to better mood the next day.

Here is what the research found, what it doesn't tell us, and how to use it in an ordinary week, plus how the Thrive Health Band shows your own link between movement and sleep.

What the new study found

Researchers followed university students who wore activity trackers for several months. The question: does it matter whether you spread exercise across the week, or do it all at once like a weekend warrior?

For sleep, frequency seemed to matter. Students who moved on more days spent more time in deep sleep, part of non-REM sleep, which is concentrated in the early part of the night. Ten minutes a day of moderate to vigorous activity was enough to see a link. The researchers describe that effort as about a 6 out of 10: breathing harder, but still able to hold a conversation.

The benefits seemed to carry into the next day too. More non-REM sleep was tied to better mood and more energy the following day, and students who moved more often reported feeling less stressed.

Two honest caveats. First, the people studied were young adults, so the team is now checking whether the same pattern holds across ages. Second, it is an observational study, so it shows a link rather than proof that exercising more often causes deeper sleep. Still, it fits with a large body of earlier research connecting regular activity with better sleep.

Why deep sleep matters

Deep sleep is the slow, heavy part of the night when your body and brain do a lot of their overnight recovery. It helps you feel restored in the morning and supports memory and mood. You get most of it in the first few hours after you fall asleep, which is one reason a late night or a broken first half of the night can leave you feeling flat.

How much deep sleep you get varies between people and with age, so your own pattern over weeks matters more than comparing numbers.

How to use this in a normal week

The encouraging part is how little it takes. Some realistic ways to move most days:

Make 10 minutes the floor, not the goal. A brisk walk around the block, a quick cycle or a short body-weight session counts. On a good day you can do more.
Spread it out. If you usually save exercise for the weekend, try adding two or three short weekday sessions rather than one big one.
Count the small stuff. Walking to the shops, taking the stairs and standing up from your desk every half hour all add up. Our article on movement breaks and sitting less at work has ideas.
Keep hard sessions away from bedtime if they wind you up. Moderate exercise in the evening is usually fine. Some find a very hard session in the hour before bed makes it harder to settle, so notice how you sleep and adjust.
Keep the Australian guidelines in view. For adults 18 to 64, Australia's 24-hour movement guidelines suggest being active for 30 minutes or more on most days, plus muscle strengthening on at least two days, with less sitting and more light activity across the day.

If you are new to exercise, are returning after a break, or have a health condition, check with your GP first about what suits you.

How Thrive shows your own link between movement and sleep

The Band has no screen, so there is nothing to check during your walk or overnight. Wear it day and night, and the Thrive by Optihealth app brings your activity and sleep together in one place.

Your sleep stages each night. Thrive shows how your night was spent across sleep stages, including deep sleep, and learns what is usual for you over time.
QQRT sleep scores. Thrive scores each night on Quantity, Quality, Regularity and Timing, and Tonight's focus suggests three simple actions for the night ahead.
Activity and workouts. Steps, active minutes and workouts are recorded in the Activity tab, so you can see how many days you actually moved this week.
Today's Vitality. Today's Vitality brings Sleep & Recovery, Heart & Nervous System, Today's Load and Mind & Mood together. Sleep is one of the inputs, so you can see how a more active week shows up in your day.
Recovery insights. After a big session, Thrive gives an estimate of how long until you are back to your usual, such as "you need 5 hours rest", so you can plan an easier day if you need one.
Ask Thrive. Try "How did my deep sleep compare on days I walked versus days I didn't?" or "How did my energy check-ins look after my more active weeks?"

Thrive also learns what is usual for you across nine areas of your health, from what the Band measures and what you log, and keeps track right across your health, including heart, temperature, stress and mood, meals and Food Fit, blood tests, medications and supplements and your medical history.

When to talk to your GP

If you are moving more and still sleep poorly most nights, or tiredness is affecting your mood, work or driving, talk with your GP. Thrive isn't a diagnosis, but Ask Thrive can help you get ready by lining up a few weeks of your sleep, activity and how you have been feeling, so you can describe the pattern clearly. Here is how to use Ask Thrive before a GP appointment.

If you want a walking buddy, trainer or someone you trust to see your progress, Thrive Loops lets you share selected information with a participating trainer, health professional or someone you trust. You decide what to share and with whom, and you can change or revoke access at any time.

Before you buy

You'll need a compatible iPhone or Android phone, because the Thrive app is on the Apple App Store and Google Play, in Australia and eight other countries. The app stores are only for downloading the app, though; they aren't where you buy the Band or a Plan. You can buy at thrivehealthband.com, or at a participating World Gym Australia location or health and wellness clinic.

The Thrive Health Band is A$660 for the first year under the launch offer. That includes the Band, which is yours to keep, and 12 months of the Thrive by Optihealth app, My Health on the web, Health Fingerprint, Ask Thrive, Thrive Loops and your data, paid once upfront. Prices are in AUD and include GST. Free Australia-wide shipping during the launch offer (usually A$14.99).

Nothing renews automatically. After your first year, you can get a new band plus 12 more months for A$660, or keep your band and renew the Thrive Connected Plan for A$240 a year, or A$29 a month with no lock-in.

You're also covered by a 12-month Thrive Care Warranty, and consumer guarantees under Australian Consumer Law always apply. See Returns if something is wrong with your purchase.

Common questions

Does exercise help you sleep?

Research links regular activity with better sleep, and a recent study found that moving on more days of the week, even 10 minutes a day, was tied to more deep sleep in young adults.

Is it bad to exercise before bed?

Moderate exercise in the evening is usually fine. If a hard session close to bedtime leaves you wired, move it earlier and see how your sleep responds.

Can Thrive show my deep sleep?

Yes. Thrive shows your sleep stages each night, including deep sleep, and Ask Thrive can compare your sleep on active and less active days.
