Sleep better together: why sleeping next to someone you love can improve sleep quality

In a world where work, family, social commitments and life’s relentless pace compete for our attention, few things feel as comforting as falling asleep each night beside someone you love. That quiet moment, when the day finally slows and you can relax, is more powerful than we often realise.

And ahead of valentine's day, it turns out that it’s not just emotional comfort at play. Science shows that sharing your sleeping space with a trusted partner can genuinely improve the quality of your sleep.

The science behind sleeping next to someone you love

Research from the Better Sleep Council (USA) highlights the role of oxytocin - often referred to as the ‘bonding hormone’. Oxytocin is released when we experience closeness and trust and it plays a key role in promoting relaxation and reducing anxiety when sleeping next to someone we feel safe with. [1]

This is supported by research from Central Queensland University, which found that oxytocin can help people fall asleep more quickly and sleep more efficiently, with increases in restorative REM (rapid eye movement) sleep — the phase of sleep most closely linked to emotional regulation, memory and recovery. [2]

Oxytocin has been shown to:

• reduce stress and anxiety by lowering cortisol levels;
• promote feelings of calm and relaxation;
• increase feelings of safety and emotional security. [3]

Together, these effects support a smoother transition into sleep and can help people stay asleep for longer, with fewer disruptions through the night. [4]

Emotional safety matters more than we think

Our brains are wired for safety. When we sleep beside someone we trust, the nervous system can ‘stand down’, reducing the need for subconscious alertness that often keeps us half-awake.

Feeling emotionally safe allows the body to down-regulate stress responses that interfere with sleep onset and fragment sleep throughout the night. From an evolutionary perspective, humans didn’t sleep alone - we slept in groups, where proximity signalled protection. Modern sleep science suggests that emotional connection still plays a meaningful role in helping us achieve deeper, more restorative rest.
