If you’re like most people, wool isn’t the fibre that comes to mind when you think of summer bedding. Maybe your immediate assumption is that wool gets hot, itchy and uncomfortable in warmer weather. And on hot summer nights, that will just lead to more tossing and turning and kicking-off of covers than usual. Fun fact: Wool is actually perfect for summer bedding and comfort. Surprised? Don’t be! Between its natural breathability and uncanny ability to both regulate temperature and wick moisture, there’s really nothing better than wool bedding, even in the dog days of summer.

Is Wool Breathable?

When we talk about breathability in bedding, it’s a reference to how well air flows through and around the materials, which allows heat and moisture to escape. Synthetic materials, like polyurethane foam and polyester, have low breathability because they’re so dense. That’s why they have a tendency to trap body heat while you sleep, which inevitably leads to overheating. Natural materials, like wool, are highly breathable. As a fibre, wool has a unique structure—it’s curled and springy, which creates tiny little air pockets when the fibres are layered or woven. Air can circulate through these pockets while also providing insulation, which is how it regulates body temperature. Wool actually evolved this way so that sheep don’t swelter when they’re roaming around a sunny mountainside, and we can put it to good use in bedding.

Breathable wool bedding, like a lightweight wool duvet, helps you sleep cooler by promoting airflow and reducing moisture build up. Wool can actually absorb up to 30% of its own weight in moisture without feeling damp or heavy. Everyone sweats at night to some degree, especially in warm weather, so this is no small thing. By pulling moisture away from your skin and releasing it into the air, wool fibres actually keep you dry and comfortable instead of damp and clammy—even when temperatures rise.

The combination of breathability and moisture management means wool is naturally temperature regulating, so it’s an ideal bedding material year-round. In the summer, it keeps you cool by releasing heat and moisture. In the winter, it insulates to create a warm pocket of air while wicking away sweat to keep you dry. Pretty cool, right?

Is Wool Good for the Summer?

On hot summer nights, it’s pretty typical to overheat in bed soon after turning in. It’s a scenario that leads to tossing and turning and eventually kicking off the covers—only to catch a chill because you’re running a fan or you cranked up the air conditioning before bed. It’s an endless cycle: overheat, chill, repeat. And in the event you do drift off at some point, your sleep is probably less than ideal—research published in the Journal of Physiological Anthropology revealed that the heat of summer can disrupt your slow wave and REM cycles. So, what can be done?

If you’re sleeping on synthetic bedding, whether that’s your mattress, your pillow, your duvet, your mattress topper or even your sheets, consider upgrading to wool. We’ve already covered its natural breathability and ability to manage moisture and regulate temperature, all of which make it ideal for summer. But there are other benefits to this wonder fibre. Because it absorbs and then releases moisture, wool reduces odours and the kind of bacterial growth that thrives in warm, damp conditions. That means wool bedding is actually fresher and cleaner. That’s appealing to everyone, but especially those with allergies. Nighttime allergies are actually more common during warm summer months, because allergens like dust mites and mould find hot, sweaty beds particularly hospitable. Switching to wool creates a much less welcoming environment, helping you breathe easier and sleep more comfortably through the night.

There’s a sustainability factor to wool bedding, too. When wool is ethically harvested and wool bedding products are responsibly produced, it’s a wonderfully eco-friendly choice. That’s something more people are prioritizing, and here at Woolroom, we love to see it!

Benefits of Summer Wool Bedding

Wool’s innate characteristics lend the fibre to every kind of bedding imaginable, from staples like pillows and duvets to mattress toppers and even the mattress itself.

Wool pillows: Wool pillows stay cool and dry all night, even in the hottest weather, so you don’t wake up with a sweaty head or neck. Unlike down, which is highly insulating because it traps heat and feels clammy when it becomes damp, or stuffy down alternatives, wool actively manages moisture and airflow for fresher, more comfortable rest.
Wool duvets: Wool duvets offer the same temperature regulating benefits, especially when you choose a lightweight summer duvet from Woolroom. Down duvets, while luxurious, trap heat and create hot, humid microclimates under the covers. Down alternatives, often made with synthetic materials, likewise lack breathability.
Wool mattress pads: Upgrading your entire mattress may not be an immediate option, but a wool mattress pad is a handy workaround. It adds a breathable, moisture-managing layer that helps regulate body temperature, and it protects your mattress, too.
Wool mattress toppers: These bedding upgrades don’t just manage temperature—they enhance comfort, too. Woolroom’s traceable wool toppers add a luxurious layer for cleaner, more comfortable nights.
Wool mattresses: Conventional beds-in-a-box are often made with polyurethane foam, which lacks the durability, longevity, sustainability, and breathability of wool. But wool mattresses aren’t just a better choice in the hottest months of the year. According to research conducted by the University of Leeds, Woolroom’s natural wool mattresses can actually boost your chances of a good night’s sleep by 67% and contribute to 25% more deep, regenerative sleep than other bedding materials.
