Wool Bedding Will Make You Sleep Better and Here’s the Proof

Forget the featherweights, evidence suggests that wool is the best bedding to pull an all-nighter.

You’ve changed your pillow, opened your windows, journalled your worries, made your partner swivel the bed orientation ninety degrees, meditated for a full five minutes (okay two and half), downed a herbal tea and left your phone downstairs but still you’re not sleeping. What now?

What is wool bedding?

For clarification purposes, this does not mean snuggling under a blanket with the DNA of a scouring pad, reminiscent of boarding school days past. Wool bedding has joined us in the 21st century and looks like any other civilized and machine washable duvet. To say that wool bedding is on the precipice of becoming a mass-adopted wellbeing trend would be doing it a disservice because the sheer weight of science-led research studies backing wool bedding mean it’s less of a moment and more of a full on movement. In short, it’s what we should have been sleeping under all along.

Duck, Duck, Goose…Sheep

The ideology of sleeping under duck and goose down has long been implanted into our desire cortexes; all that exquisitely airy, puffed-up softness collected from a crystalline Hungarian winterscape or some other frost-laden tundra. It paints a beautifully Tolstoyan scene but in reality, this misplaced luxury is what’s stopping you from getting a good night’s sleep. As soon as people started sleeping soundly under weighted blankets, the plumage jig was up. Add to that the galling animal welfare reports of live plucking, (every bit as horrifying as you’d imagine), and it seemed we’d all be faced with switching to synthetics. Fear not, the answer is pleasingly organic and cottage core, wool bedding.

9 times science proved wool bedding improves your sleep

1. Wool bedding keeps you in restorative sleep stages for longer

Wool is scientifically proven to make you sleep better. In a pivotal sleep study, participants observed zedding under wool spent 25% more time in Stage 4 Restorative REM sleep, those hours between 2am and 5am, when cells regenerate and the body heals itself. Participants reported sleeping more peacefully and waking up feeling well rested.

2. Wool bedding lessens tossing and turning

The physiological make-up of wool has the added benefit of diffusing weight over pressure points and evidence shows that when you sleep on wool underlay, you shift around less to avoid tender points, finding a comfortable position more easily.

3. Wool has in-built climate control

Sleep scientists have discovered that the main cause of nighttime waking is not our racing, spaghetti-like thoughts but the diminishment of the body’s ability to thermoregulate during deep sleep. Wool creates a stable sleep environment, thus helping the body regulate its own temperature to maintain a balanced sleep thermostat.

4. Wool’s best if you sleep cold too

The inherent natural 3D crimp of the wool fibre traps pockets of still air, thermo-insulating your skin from the cold environment. Studies show that when pitted against feather down and synthetics, on a cold night, wool will warm you up faster than both feather down or synthetic duvet equivalents.

5. Wool is moisture wicking

Wool is an active fibre and as such, is unrivalled in its moisture transport abilities. “Wool absorbs perspiration as you sleep and acts as a filter system, releasing it into the atmosphere during the day, therefore managing humidity as you sleep,” explains Chris Tattersall, owner and sleep expert at Woolroom.

6. Sleeping in wool is sleeping quicker

Nowhere near as saucy as silk but wearing merino wool sleepwear showed that at 17°C, (the body’s optimal sleep temperature range), wool sleepwear significantly increased sleep onset quicker than cotton.

7. Wool bedding makes for restful sleep

More wool is needed to create the same thermal comfort as down and is therefore heavier. Just like weighted blankets, this added load has the effect of calming the parasympathetic nervous system.

8. Wool is fully hypoallergenic

Those who suffer from asthma or other allergies are more sensitive to house dust mites. “Wool filling, through its ability to maintain a dry state, does not allow house dust mites to live within the bedding environment as there is no food source,” explains Chris Tattersall.

9. Wool bedding is better for sleeping partners

Less shifting about and fewer nighttime waking episodes spell out a sounder sleep for your sleep buddy but the creation of a micro climate means wool bedding also regulates temperature across the bed. According to a study by Woolroom, 71% of us sleep at a different preferred temperature to our partner, so if you have a hot partner, they’ll cool down rather than making you toasty too.

Sleep is a super power. Poor sleep results in poorer quality of life; impairing cognitive function, weakening the immune system, lessening mental resilience and compromising cardiovascular health. Getting your sleep sorted touches every aspect of wellbeing and there are fewer things more fundamental to our long-term health. The melee of modern life is unavoidable and so should it be, let's all relish buzzing throughout the day but have the tools to stop it entering our bedrooms and compromising our sleep. As it turns out, it really is those sheep that get us to sleep.
