How sharing a bed impacts sleep

By Callie Paige

Before we start, when we say ‘share a bed’, we’re referring to literally sharing a bed…not… y’know, “sharing a bed”.

Apparently 60% of us share a bed with someone, and we’re often quick to complain about their sleeping habits. They snore too loud. They hog the covers. They move too much. All valid points, and we’re not just talking about men here (we’re all about equality, right?!).

It turns out that an annoying bed partner can reduce the quality of your sleep by 13%. There’s a stat to pull out next time you’re arguing! Plus, dyadic sleepers actually experience less REM sleep because of disturbances. For those of you that don’t know, REM sleep is the final stage of four cycles that your body goes through multiple times during sleep (we talked about this in one of our other blogs - Why is sleep important?

However, for all the negatives, the benefits of sleeping together outweigh the drawbacks - in our opinion anyway!

Let us explain:

If you have a partner that you’re used to sleeping with, and for whatever reason you spend a night apart, you wake up feeling a bit strange - right? Attachment anxiety is usually reserved for children, but it’s rife in adults too.

Over the weeks, months, years, we get used to having someone next to us. If this person suddenly isn’t there, research suggests that we show higher levels of the stress hormone, cortisol.  

We also can’t scientifically prove this one, but Psychology Today think there’s more to sleeping together than just the facts. Feeling a little ‘off’ isn’t uncommon when we’ve not slept in the same bed as our partner, whether it’s because of an argument, staying up to watch something, or just nodding off on the couch.

PT believes that we exchange some kind of energy with the person we sleep with. Even they’re wary of getting a bit too ‘New Age’, but it’s something I think we can all identify with. Energy, state of mind, whatever you decide to call it, you can see outside influences impacting your sleep in many different ways, such as meditation (you can read more about that here).


So it’s decided. Sleeping together is better than sleeping alone. You can quote us on that. All that’s left to do is minimise the problems.

Moving too much and being disturbed, the official term being ‘motion transfer’, is often a sign of a poor quality mattress.

The go-to answer for that is ‘get a memory foam mattress’. We can tell you first hand, memory foam mattresses can be equally as bad as sprung mattresses for motion transfer. It all depends on the foam.

We’re not ones to name and shame, so we’ll simply provide you with a solution. Sid.

Sid can reduce motion transfer by up to 85%, because of the high quality mix of technologies that goes into each of our mattresses.

And when it comes to sharing your bed, let’s just say we’re advocates. Spread the love.
