Should you use separate duvets? Experts uncover the benefits of a Scandinavian sleep method

Couples who share a bed don't always sleep better. Be it through duvet hogging, leg kicking, or even star-fishing, it's quite common for a partner to disturb your sleep. Yet this only seems to be an issue outside of Scandinavia. It seems Northern Europeans have solved the fidgety partner problem. 

In fact, for centuries, they've been sleeping with separate duvets instead of sharing one – also known as the Scandinavian sleep method. Supposedly, switching out your queen-sized comforter for two singles is key to undisturbed sleep. It's been tried and tested by many and confirmed to have worked. This Scandi-sleep hack has saved sleep and many relationships. 

But what are the actual benefits? We've spoken to the sleep experts for their thoughts and whether there's any scientific backing behind sleeping with separate duvets. If it sounds like something you'd like to try, I've also included some of the best duvets you can buy, in a twin size – so you can get back to sleeping soundly. 

What is the Scandinavian sleep method?

According to Alison Jones, sleep expert at leading mattress brand Sealy, 'sleeping in the same bed as someone else and sharing a duvet with them can reduce sleep by 30%.' The Scandinavian sleep method provides a solution; it's the practice of sleeping under two separate duvets or comforters rather than sharing one large-size cover. It was traditionally used in Scandinavian countries to help tackle the problem of one partner getting cold in the night.

Yet it's also a method James Wilson, aka The Sleep Geek, swears by when the weather gets warmer. He states 'As temperatures rise, it may mean sweatier nights are on the horizon – throwing our sleeping patterns easily off track.' The Scandinavian sleep method sees bed sharers having separate duvets to help 'regulate body temperature as the night gets warmer'.

The benefits of sleeping with a single duvet

'The Scandinavian sleep method may seem unusual to some, but it has some real advantages,' explains sleep specialist, Dr Walt Pickut. 

Personalized comfort: 'Each partner having their own duvet allows for customized comfort,' says Dr Pickut. 'You can choose the thickness and material that suits you best, without compromising your partner's preferences. This could potentially lead to fewer sleep disturbances, and hence better quality sleep.' 

Temperature regulation: If you're a hot sleeper, laying next to someone will make you hotter, as you both transfer body heat. Separate duvets will ensure your temperature stays regulated as much as possible. Getting your own cooling duvet is likely the best solution here. It also means you both have enough duvet. James Wilson states 'separate duvets, not only give a better temperature for sleep but also stop you from fighting over who has the most duvet too. Win, win.'

Motion isolation: The arrangement of having your own duvet means you're less likely to kick or nudge your partner in the night, giving you more freedom to move around as you, please. This will mean both parties can sleep soundly. As Dr. Walt Pickut confirms 'the less you're disturbed, the more likely you are to stay in the deeper, more restorative stages of sleep.'

In addition, while serving as director of education for the Anesthesiology Department at Jersey City Medical Center early in my career, he completed all hospital-based clinical rotations in Clinical Diagnosis through New Jersey College of Medicine.

The drawbacks of sleeping with a single duvet

While there aren't any scientific drawbacks to using single duvets, some say it can reduce the feeling of intimacy between two people. Of course, this will depend on the individual couple and how they feel. Alison Jones advises, 'A way to overcome this is to upsize the duvets or blankets used to ensure there is not a gap between each person.' 

The main negative of the Scandinavian sleep method is cost. Buying two separate duvets will be more expensive than one – even when opting for single/twin sizes. Typically, a good duvet can cost anything above $100, though you can get cheaper duvet inserts on Amazon. Whatever duvet you choose, just remember, you'll have to double its price for two. Though if there's anything worth investing in, it's sleep.

Should you try it?

Some couples prefer the intimacy of sharing a duvet, but others would rather prioritize their own sleep needs. 'As with all sleep strategies, what works best is highly individual,' adds Dr. Walt Pickut, 'The Scandinavian method is a great solution for some, but it's important to experiment and find out what enhances your own sleep quality the most.'

So before ditching the duvet, Alison Jones suggests to 'consider things like your sleep position, temperature, bedtime routine and overall sleep environment (such as your mattress).'
