If you've ever woken up at 2am kicking off the covers, peeling off a damp shirt, and silently bargaining with your own body temperature — this one's for you.

Night sweats are one of the most common complaints we hear from our customers. And one of the first questions we always get is: "What should I be sleeping in?"

Cotton is the classic answer. It's what most of us grew up wearing, it feels familiar, and it's everywhere. But bamboo has been quietly earning a reputation as the better option — especially for women navigating perimenopause and menopause. So which one actually delivers?


First, Why Fabric Matters More Than You Think

Your body does a lot of work while you sleep. It regulates temperature, releases moisture, and cycles through stages of rest that require genuine stillness. When your sleepwear works against that process — trapping heat, absorbing sweat and holding it against your skin, or restricting movement — it disrupts everything.

For women going through hormonal changes, the stakes are even higher. Hot flashes and night sweats aren't just uncomfortable; they fragment sleep in ways that compound over time, affecting mood, energy, and overall health. What you wear to bed isn't a small decision — it's a health decision.


Let's Talk About Cotton

Cotton is a natural fibre, breathable in moderate conditions, and easy to care for. For most sleepers in most seasons, it's perfectly fine.

But here's the catch: cotton absorbs moisture well, but it doesn't release it efficiently. When you sweat, cotton holds that dampness against your skin. You've felt it — that heavy, clammy feeling in the middle of the night that makes you want to change your entire pyjama situation at 3am. Cotton also doesn't regulate temperature particularly well; it can feel warm and heavy even in lighter weaves.

For light sleepers, cotton is lovely. For hot sleepers and women dealing with night sweats? It often makes things worse, not better.


Now Let's Talk About Bamboo

Bamboo viscose (sometimes called bamboo rayon) is a different category entirely. Here's what makes it genuinely special for warm sleepers:

It Wicks Moisture Away From Your Skin

Rather than absorbing sweat and sitting with it, bamboo pulls moisture away from your skin and disperses it through the fabric so it can evaporate. The result? You wake up feeling dry, not damp. This single difference is the reason so many women describe switching to bamboo as life-changing.

It Regulates Temperature Naturally

Bamboo fibre has a naturally porous structure that creates microventilation against the skin. This means it responds to your body temperature — keeping you cool when you're running hot, and comfortable when temperatures drop. Unlike synthetic cooling fabrics that work mechanically, bamboo does it naturally.

It's Silky Soft Against Sensitive Skin

Hormonal changes during perimenopause and menopause can make skin more reactive and sensitive. Bamboo is naturally hypoallergenic, anti-microbial, and has an incredibly smooth fibre structure that doesn't irritate. Many women who experience "menopause itch" or heightened skin sensitivity find bamboo is the only fabric they can comfortably sleep in.

It Gets Softer With Every Wash

Good bamboo sleepwear doesn't degrade with washing — it improves. Our Georgia Rylan pieces are designed for exactly this: a luxurious softness that deepens over time, so your favourite pyjamas keep getting better.

What We Recommend at Cloud Nine

For women navigating night sweats, perimenopause, or menopause, we consistently point people to our Georgia Rylan bamboo collection. It's our in-house brand, designed right here in Canada specifically for this. Every single piece is made from a 95% bamboo, 5% spandex blend — OEKO-TEX certified, beautifully designed, and sized from XS to 3XL.

We designed Georgia Rylan because we kept hearing the same story from our customers: I've tried everything, nothing works. We wanted to change that.

If you're a generally cool sleeper who loves a classic feel, a lovely cotton pyjama from our PJ Salvage collection will treat you very well. But if heat and moisture are your nemesis at night, bamboo is where the real difference happens.

Frequently Asked Questions |

Is bamboo actually better than cotton for night sweats?

For most women dealing with night sweats, yes — bamboo significantly outperforms cotton. The key difference is in how each fabric handles moisture: cotton absorbs and holds it against your skin, while bamboo wicks it away and allows it to evaporate. Most women who make the switch describe it as an immediate improvement.

What percentage bamboo should I look for in pyjamas?

Our Georgia Rylan collection uses 95% bamboo viscose and 5% spandex. The bamboo content is what delivers the moisture-wicking and cooling properties; the spandex adds a lovely four-way stretch that makes them comfortable to move in. Avoid blends with a lot of polyester, which will trap heat.

Are bamboo pyjamas good for perimenopause, not just full menopause?

Absolutely. The hormonal fluctuations of perimenopause can begin years before the official menopause transition, and many women start experiencing night sweats and temperature sensitivity well before their periods stop. Bamboo is equally effective at any stage of the hormonal journey.

Is bamboo sleepwear safe for sensitive skin?

Yes. Our Georgia Rylan bamboo is OEKO-TEX certified, meaning it's been tested for harmful substances and is safe for sensitive skin. Bamboo fibre is naturally hypoallergenic and anti-microbial, making it an excellent choice for anyone with eczema, skin sensitivities, or heightened reactivity during menopause.
