Why is Summer Sleep so Hard? Here's What Might Be Hiding in Your Bedroom
Struggling to sleep on warm nights often has less to do with the weather and more to do with whether you are using the right summer bedding for heat, airflow, and comfort.
Longer days. Bright evenings. Ice creams on the patio. British summer has its charm, but what about those nights when you're just lying there, wide awake, one leg out of the duvet, fan blasting, wondering if anyone "ever" sleeps well in July?
If that sounds familiar, let's ask the obvious:
Is it the heat or is it your bedding?
You're Not the Only One Struggling
When temperatures creep past 25°C indoors, your body finds it tough to cool down enough for deep sleep. That natural drop in core temperature (which helps signal your brain that it's bedtime) can't happen. Result? You feel sticky, restless, and wake up tired.
While we often blame the weather, the truth is that what you're sleeping in makes a massive difference, especially when it comes to choosing the right summer bedding.
Search data consistently shows a spike in queries like “can’t sleep in summer,” “night sweats,” and “best bedding for hot sleepers” between June and August in the UK. This is not a coincidence. Summer sleep problems are widespread, and they are not just about the weather.
Is Your Bedding Making Things Worse?
Let's be honest. Most of us don't think much about our sheets. We focus on colours, maybe thread count, maybe if it matches the curtains. But in summer, the "material" matters most.
Ever wake up damp and hot despite the window being open? That could be your bedding telling you it can't breathe.
Cotton Vs... Well, Everything Else
Here's where it gets real. Not all fabrics are created equal, and some are downright sleep-sabotaging in summer, especially when used as summer bedding:
Polyester & Microfibre
Trap body heat X Don't absorb sweat X Stick to your skin X Feel cheap and shiny (because they are)
They might wash easily and look fine at first but when it's muggy? It's like sleeping in cling film.
Flannel (Yes, some people use this year-round)
Warm, cosy and perfect... for December. In July? You'll wake up gasping!
Even some so-called 'summer flannels' are heavy and airflow-blocking.
Why Choosing the Right Summer Bedding Can Transform Your Sleep
100% Cotton Difference
This is where cotton makes a genuine difference and why it remains one of the best choices for summer bedding.
Natural cotton fibres allow air to circulate freely, helping excess heat escape rather than build up. Cotton absorbs moisture from the skin and releases it into the air, keeping you feeling dry and comfortable throughout the night.
High quality cotton bedding feels cool when you first get into bed, stays breathable as you sleep, and softens naturally with every wash. It does not rely on chemical treatments or artificial cooling technologies. It simply works with your body.
At Leruum, we use 100% cotton because it is gentle, breathable, and reliable. It is the kind of fabric you would happily choose for your children, night after night.
“I Never Really Checked What My Sheets Are Made Of”
You are not alone. Many people assume their bedding is cotton, only to discover it is a polyester blend when they check the label.
If your sheets say polyester, microfibre, or cotton blend, that could be the hidden reason behind broken sleep and night sweats. Small changes, like switching to pure cotton bedding, often make a noticeable difference within the first few nights.
Leruum's Summer Bedding: Cool, Classic, and Honestly Just Lovely
These days, it’s easy to get swept up in techy promises: 'cool-touch fibres', 'smart climate gels', 'moisture-reactive nano blends'. Clever-sounding stuff. But does it help you sleep better? Sometimes. Often... not quite.
Cotton has been trusted for generations, and with good reason. It's naturally breathable, soft on the skin, and it just works.
At Leruum, every bedding set is thoughtfully crafted from 100% cotton, designed to keep you cool and comfortable without compromising on style. Our fitted sheets stay put, even when you don’t. Pillowcases stay cool to the touch, long after you’ve drifted off. And duvet covers? They look crisp, but feel like drifting into a cloud.
So if sleep has started to feel like a struggle, if you're waking up clammy, restless, or not quite rested, maybe it’s not you. Maybe it’s your bedding.
Try cotton. Try Leruum. Sleep the way nature intended.
