With temperatures across the UK climbing above 30 °C, disrupted sleep is all too common.
A smart bedding switch can make summer nights feel crisp and cool without expensive gadgets. Leruum’s 100% cotton bedding is designed for exactly this. It is breathable, lightweight, and made to help you drift off even in the thick of a heatwave.
Pick the Right Fabrics, Go Pure Cotton
When it comes to staying cool at night, fabric matters as much as weave. Cotton percale, which is crisp, matte, and naturally breathable, allows heat and moisture to escape instead of trapping them.
Leruum’s 100% cotton bedding in fresh seasonal tones such as White and Magenta Ditsy or Olive Green and Lime delivers comfort without cling. A cotton sheet feels cool the moment you slip into bed, giving your body the airflow it needs.

Choose the Right Thread Count for Summer
Thread count plays a role in how breathable your bedding feels. In hot weather, look for a balanced count such as 200TC in percale or sateen, which offers a cool, crisp feel without being heavy.
For a touch of personality alongside comfort, try:
- Purple and Grey Polka Dot Cotton Set, playful yet cooling
- Aqua Blue Luxury Cotton Set, fresh and airy with a hint of elegance
These lighter-feeling fabrics give you flexibility, so your bed stays comfortable from dusk until dawn.
Evening Routine, Simple Heat Hacks
A few small adjustments before bed can drop your room temperature by several degrees:
- Keep blinds closed on sun-facing windows until sunset
- After sundown, open a window and set a fan to draw in cooler outdoor air
- Keep a chilled water bottle at your bedside, wrapped in cotton to prevent condensation drips
- If you have attic hatches or high vents, open them to release trapped hot air
Quick Wins with What You Already Own
No need to overhaul your bedroom, just tweak what is already there:
- Freeze a bottle, wrap it in a tea towel, and place it at your feet for an instant cool down
- Swap heavy throws for Leruum’s lightweight cotton throws or a flat sheet
- Change pillowcases first; cotton sateen or percale will breathe far better than synthetic blends
Even small changes to fabrics can noticeably reduce overnight heat buildup.
