More than two in five Australian adults aren’t getting enough sleep, and poor sleep is increasingly recognised as a public health issue – not just an individual one. When disrupted sleep becomes a nightly pattern, it can affect mood, communication, and how we show up in our relationships.
For some couples, sleeping in separate beds – or even separate rooms – can feel like a big step. But for others, it’s a practical adjustment that supports both better rest and better connection. Here’s what the research tells us, and how to approach separate sleeping arrangements in a way that supports your relationship rather than undermines it.
Why sleep matters – for individuals and relationships
Mounting research continues to show that sleep is essential for both physical and mental wellbeing. Adults generally need seven to nine hours of quality sleep each night, including enough deep and REM sleep to feel restored.
Data from the Australian Institute of Health and Welfare shows that ongoing sleep problems are linked to:
- higher levels of psychological distress
- increased risk of anxiety and depression
- reduced emotional regulation and patience
Sleep deprivation doesn’t stay neatly contained in the bedroom. Research consistently shows that when people are overtired, they’re more reactive, less empathetic, and more likely to misread their partner’s intentions – all of which can fuel conflict.
There’s also a broader impact. Economic modelling suggests that insufficient sleep continues to cost the Australian economy tens of billions of dollars each year through lost productivity, workplace accidents, and increased healthcare use.
What happens when partners disrupt each other’s sleep?
Even in close, loving relationships, partners don’t always make ideal sleep companions. Common challenges include:
- snoring or sleep apnoea
- restless movement
- different body clocks or chronotypes
- shift work or on-call hours
- different wind-down routines
Australian sleep research shows that bed-sharing can increase micro-awakenings, particularly for light sleepers. Over time, these repeated disruptions can leave one or both partners chronically overtired – even if they technically spend enough hours in bed.
Why some couples choose to sleep separately
Sleeping separately isn’t new, but it is becoming more openly discussed. While it’s still common for couples to share a bed, there’s growing recognition that one size doesn’t fit all when it comes to sleep.
Australian household data from the Australian Bureau of Statistics shows a continued rise in single-person households and more diverse living arrangements, reflecting broader shifts in how people approach intimacy, independence, and wellbeing.
Couples may choose separate sleeping arrangements for many reasons that don’t signal relationship trouble, including:
- prioritising sleep quality during demanding life stages (parenting, caring, illness)
- managing health conditions
- needing physical or sensory space to decompress
- navigating different work or sleep schedules
For many, it’s less about emotional distance and more about what’s sustainable for their lifestyle.
It’s worth acknowledging that separate sleeping isn’t an option for many couples, especially where housing constraints, financial pressure or family responsibilities shape what’s possible.
Sleeping separately doesn’t have to signal problems in the relationship
There’s a strong cultural belief that “good couples” sleep together. But closeness isn’t measured by proximity alone.
In long-term relationships, it’s normal for needs around space and closeness to change over time. Early relationships often involve lots of physical reassurance – sitting close, touching often, sharing space. As trust and security deepen, couples may rely less on constant physical proximity to feel connected.
Importantly, sleeping separately doesn’t have to reduce intimacy or sexual connection. Many couples who sleep apart intentionally prioritise:
- shared bedtime routines (talking, cuddling, checking in)
- planned time for intimacy that isn’t dependent on sleep
- emotional closeness during the day
When chosen consciously and communicated openly, separate sleeping can support – rather than erode – relationship satisfaction.
How to make your relationship work when you sleep separately
There’s no “right” way to do this, but communication matters. It can help to reflect together on questions like:
- Did this arrangement evolve without a clear conversation?
- Does sleeping separately stir up worries about rejection or distance for either of you?
- Is this change connected to other challenges around intimacy or communication?
- Do you still feel like partners, or has it started to feel more like living parallel lives?
If concerns come up, it’s worth talking them through gently rather than letting assumptions fill the gaps.
It’s also important to address practical contributors:
- Would medical support help with snoring or sleep apnoea?
- Are work or screen habits making sleep harder than it needs to be?
- Are you finding other ways to stay emotionally and physically close?
Finally, check in over time. What works during one season of life may need adjusting later and that’s okay.
Good sleep supports patience, emotional regulation, and connection – all vital ingredients in healthy relationships. For some couples, sleeping separately is a temporary fix, while for others, it becomes an ongoing, mutual choice.
