Sleep divorce: should you and your partner sleep apart?

One of you runs hot, the other wants the doona. One snores, the other lies awake listening. One is up at 5am for work, the other reads until midnight. Sooner or later, someone ends up on the couch, and the question comes up: would we both sleep better apart?

It has a name now, "sleep divorce", and Australians are talking about it more openly. This week the opposite idea was trending on X too: posts about feeling instantly drowsy next to someone you trust, linked to the bonding hormone oxytocin. Both can be true. Sharing a bed can feel safe and close, and it can also cost you sleep.

Here is what the research and Australian experts say, how to decide what suits you both, and how the Thrive Health Band can show what actually happens to your sleep on nights together and nights apart.

How common is sleeping apart?

More common than you might think. ABC reporting in March 2026 cited recent data showing about 18% of couples sleep separately. ResMed's 2025 Global Sleep Survey, reported by news.com.au, found that roughly one in five Australians had tried a "sleep separation", and of those, 61% said their sleep quality improved. Snoring, restlessness, different schedules and heat were the usual reasons.

It does not work for everyone, though. In the same survey, a sizeable group said their sleep stayed the same or got worse, and some felt their relationship suffered.

Why sharing a bed can help

Sleep is not just physical. Feeling safe helps you switch off, and for some couples the presence of a partner makes it easier to fall asleep and feel settled. Bedtime is often the one quiet time of day you get together, for a chat, a cuddle or just winding down side by side.

If you sleep well together, there is no reason to change. This is about choice, not a trend to follow.

Why it can cost you sleep

The common culprits are practical:

• Snoring and restlessness. Noise and movement can wake a light sleeper many times a night, often without them remembering.
• Different body clocks. A night owl and an early bird keep pulling each other's sleep out of shape.
• Shift work and early starts. Alarms and late arrivals break up the other person's night.
• Temperature. With a warm spring forecast for much of Australia, one hot sleeper can make the whole bed uncomfortable.
• Kids and pets. Small visitors in the night add up.

As Relationships Australia NSW put it to the ABC, sleeping apart is often framed as a relationship issue, but it is usually a sleep issue first.

How to decide together

If you are thinking about it, a few ideas from Australian relationship and sleep experts:

1. Talk about it as a sleep decision. Make it clear the aim is better rest, not distance. Agree on why you are trying it.
2. Try small fixes first. Separate doonas, a bigger bed, earplugs, a fan on your side, or a later bedtime for the night owl can make a real difference.
3. Try a part-time version. Some couples sleep apart only on work nights, or start the night together and move later.
4. Keep your connection rituals. Time in bed together before sleep, coffee together in the morning, or a regular evening walk keeps closeness that does not depend on sharing a pillow.
5. Set a review date. Try it for two weeks, then check how you both feel.

If tension about the arrangement keeps coming up, a counsellor can help you both talk it through.

How Thrive helps you see what is really happening

Deciding on gut feel is hard, because you rarely know how often you woke. Thrive gives each of you your own picture. The Band is screenless and light on the wrist, so there is nothing glowing in the dark to disturb the other person, and the Thrive by Optihealth app shows your night when you are ready to look.

• QQRT sleep scores. Thrive scores each night on Quantity, Quality, Regularity and Timing. Quality reflects time awake during the night, so it is a useful one to compare.
• Your sleep stages. See how each night was spent, including deep sleep, and how that sits against what is usual for you.
• Check-ins. A quick morning mood and energy check-in shows how you felt, not just how you slept.
• Experiments. Insights includes guided experiments you can start from a set list. For a change like two weeks of separate doonas, compare your sleep scores before and after.
• Ask Thrive. Try "How did my sleep quality compare on the nights I slept in the spare room?" or "How was my energy after nights with fewer wake-ups?"

Thrive learns what is usual for you across nine areas of your health, not just sleep, 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.

If you both wear a Band, 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.

When to talk to your GP

If your partner notices loud snoring with pauses in breathing or gasping, or either of you feels unrefreshed most mornings despite enough time in bed, 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 and how you have been feeling. Here is how to use Ask Thrive before a GP appointment.

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.
