Why your bedding is making it worse

You've tried everything. Earlier bedtime. No screens. A fan pointed directly at the bed. And yet you're still waking up at 3am, kicking the covers off, waiting for a cool patch that never quite arrives.

Here's something worth considering: your bedding might be working against you.

The problem with most bedding

Most mainstream bedding is made from cotton, polyester, or a blend of the two. These fibres are fine for everyday use, but they have a significant limitation when it comes to sleep: they trap heat.

Cotton absorbs moisture but holds onto it, creating a warm, close environment around your body that gets worse as the night goes on. Polyester is even less breathable, acting almost like a second skin that seals in warmth rather than releasing it. Neither material responds to changes in your body temperature. They just sit there, getting hotter.

For light sleepers or those who run warm, this can be enough to pull you out of deeper sleep stages repeatedly through the night, even if you don't fully wake each time.

Heat and sleep are in constant negotiation

Your core body temperature naturally drops as you fall asleep. That drop is part of what signals to your brain that it's time to rest. The problem starts when your bedding prevents heat from dissipating properly, pushing your temperature back up before you're ready to wake.

The result is fragmented sleep: lighter, more restless, and far less restorative than it should be. You might not connect this to your bedding at all. It's easy to put it down to stress, age, or just the way things are now.

But the material around your body for seven or eight hours each night has more influence than most people realise.

What actually helps

The difference lies in how a fabric manages heat and moisture, not just how it feels to the touch. Fabrics that actively wick heat away from the body, release moisture quickly, and remain breathable throughout the night create a fundamentally different sleep environment.

This isn't about sleeping cool in the way a cold shower feels cold. It's about maintaining an even, stable temperature so your body can do what it's designed to do: rest.

Bedding made from TENCEL™ lyocell fibres works in precisely this way. The fibre structure draws heat and moisture away from the skin and releases it efficiently, keeping the surface temperature consistent through the night. It's noticeably different from the first time you use it, and more so over time as you stop bracing for the heat that used to wake you.

Sometimes the simplest change has the most impact. If you've tried everything else, it might be worth starting with what's closest to you.
