Sleep Together, Love Together: How Co-Sleeping Boosts Relationship Intimacy

The numbers vary from study to study, but many surveys from reputable sources like Sleep Foundation and discussions on Sleep Advisor suggest that nearly one in five couples choose to sleep in separate beds — a trend often referred to as "sleep divorce." This trend has notable implications for relationship dynamics. Yet, co-sleeping can offer both emotional intimacy and physical benefits that enhance a couple’s connection. In this article, we’ll explore the science behind these sleeping arrangements and the practical aspects of sharing a bed.  

What’s the science behind sleep and emotional bonds in relationships?

So, what do the boffins say on the matter? One thing to consider is sleep concordance – according to PubMed, this is measured by how much time couples spend awake and asleep at the same time. By aligning your sleep patterns (going to sleep and waking up at similar times) you can achieve better sleep quality, lower levels of depression, and an overall better harmony in your relationship.

Physical closeness throughout the night, particularly if you’re cuddling or holding hands, can actually release a hormone called oxytocin. This hormone lowers your stress levels and helps promote relaxation! Sharing a bed is also known to improve your mood and communication: pillow talk is a real thing, and chatting about your day or your future before you drift off is a great intimacy booster.

What physical benefits come from co-sleeping as adults?

Sharing a bed is great for your relationship but it also has physical, real-time benefits to help improve bedtime. Sleeping together can actually regulate your body temperature, which is key to a good night’s rest – by sharing body heat, you create a stabilised microclimate between you and your partner, which is amazing when you think about it.

By releasing oxytocin and also lowering cortisol production, sharing a bed with your partner can improve your heart health. According to research by Pavel Goldstein, a synchronised heart rate, achieved by sleeping next to somebody, is also known to reduce cardiovascular strain.

And of course there’s the physical comfort of being snuggled up next to somebody – and with the right bedding, like soft, thermoregulating and hypoallergenic bamboo bedding, you can enjoy the perfect night’s sleep with the one you love.

How can couples navigate common sleep challenges?

If you’re wondering how to sleep with a snoring partner, then you’re not alone. There are a lot of sleep challenges that might happen when sharing a bed with somebody, and it’s not all sweet dreams… To overcome snoring, your partner can try using a different pillow type (a higher loft height, for example, or something more breathable) or sleeping in a different position. You might want to opt for earplugs if it gets really bad!

When you and your partner have different sleep schedules, this can be tough; if they need to get up early for shift work, then they are likely to go to bed a lot earlier than you. To minimise the risk of waking them up when you do get into bed, choose a mattress that has good motion control. This will stop any movement being transferred throughout the bed, letting them get the sleep they need. When it comes to mattress types for couples sleep experts will often recommend hybrid mattresses and those with good edge support as bedding solutions for different sleep schedules.

With any sleep disorders, such as restless legs syndrome or insomnia, there can be a knock-on effect that results in the partner who isn’t suffering themselves being woken up too. Investing in high-quality bedding and a really comfortable, supportive mattress can help manage these disorders and keep both of you sleeping well.

What psychological benefits does sleeping together offer?

The benefits of sleeping together for couples are plentiful – sharing a bed can decrease your anxiety levels, building a sense of safety from being physically close to another person. By improving your emotional connection, sleeping together improves mental health within relationships; you’ll notice increased intimacy, more enjoyable sleep, and potentially lower rates of depression. A study published in Psychosomatic Medicine linked sleeping together with better mental health outcomes, thanks to improved sleep efficiency and reduced nighttime awakenings.

When it comes to the mental health benefits of sleeping with a partner (or even a pet!) is the emotional security provided by sleeping beside a loved one. Over time, this will help you feel safe and secure in your relationship, leading to increased happiness over time.

Practical tips for sleeping better together

Let’s get down to business: how to sleep better with your partner. Improve your sleep hygiene – this relates to having a consistent bedtime routine, choosing a mattress that supports you both, and ensuring your bedroom environment is conducive to sleep. It should be dark and quiet enough and neither too hot nor too cold.

When it comes to bedding solutions, there are plenty! You could opt for two single duvets, so you can each choose your TOG rating, and nobody will be stealing from anybody and introduce a mattress topper if your current mattress is too firm or too soft. Opt for bedding that feels gentle on the skin and is also thermoregulating, so you won’t get too hot even if you are a couple who love to cuddle…

When it comes to managing sleep disruptions, try not to let it get on top of you – if your partner snores, look for solutions rather than getting angry. They actually can’t help it! Talk through your issues rather than immediately heading off to the spare room, and you’ll likely find that you can work things out before it gets to the ‘sleep divorce’ stage.

Myth-busting: when sleeping apart makes sense

Of course, we should mention that sometimes there are scenarios when sleeping apart really might be the best option. If one of you is poorly with the flu, for example, and you don’t want to pass it on – separate beds are a good idea! And if one of you works nights, sleeping during the day, then of course you will likely be sleeping separately. If you’re really struggling to get past arguments about snoring or wriggling, then sleeping apart might be best for you both. But don’t forget to communicate and talk through these issues before resorting to this!

It’s all about balance; snuggle up in bed for a couple of hours before one of you heads to the spare room, and be sure to try the odd night together here and there to see if you can get back to sharing a bed full time.

How sharing a bed can enhance your relationship

Sharing a bed and sleeping together can really nurture your relationship, enhancing intimacy and even regulating your temperature. It leads to improved connections and better mental health – and it fosters improved communication in a lot of ways, too. Think about your sleep environment and whether it works for you both; do you need a more comfortable mattress with better motion control, or would softer, thermoregulating bedding be a good investment? Don’t let yourself end up in a sleep divorce…
