Why You're Still Too Hot For Bed
Autumn's arrived, the heating's gone on, and you're still lying on top of the covers at 2am wondering why your body didn't get the memo. If that's you, you're not doing anything wrong - and it's very rarely about willpower, or how many layers you've piled on.
Most of us think about tog ratings and thread counts and never once think about fibres in our pyjamas - which is odd, because the fibers are doing most of the work.
Cotton absorbs moisture but holds onto it, which is part of why a cotton nightshirt can end up feeling damp and clingy rather than actually cooling you down. Synthetic fabrics like polyester trap heat close to the skin, which is exactly what you don't want at 2am.
TENCEL™ fibres work differently: their structure allows moisture to be absorbed and released rather than held, which supports a drier microclimate against the skin - the fancy way of saying you're less likely to wake up sticking to the sheets. It's also why we create our pyjamas from TENCEL™ Modal. The fibres are naturally moisture-wicking and breathable
Go short. A short-sleeve pyjama set gives heat somewhere to go, especially useful if you're the one shoving a duvet off at midnight while everyone else in the bed is still under it
This is where long pyjamas and separates earn their keep - not because long sleeves trap more heat, but because breathable fabric means you can layer up or strip back without the clammy discomfort synthetic fabric brings.
Look for moisture-wicking, breathable fibres. TENCEL™ Modal and similar wood-based fabrics are designed to move moisture away from the skin rather than trap it, unlike most synthetics.
Yes - TENCEL™ fibres are structured to absorb and release moisture, which supports a drier feel against the skin compared with fabrics that hold moisture close to it.
Most sleep guidance points to somewhere around 16–18°C as the comfortable range for most adults, though it's worth adjusting to what actually helps you personally
If they're frequent, heavy, or paired with other symptoms that concern you, yes - a GP can help rule out the various possible causes rather than you guessing at home.
Nobody needs a lecture on thermoregulation to get a decent night's sleep. But it does help to know that the fix probably isn't another blanket, or gritting your teeth through a too-hot cotton nightie until spring. It's usually simpler: better fabric, worn well.
