Too Hot to Sleep? How to Stop Overheating at Night with Cooling Beds & Bedding
Tossing, turning, and waking up sweaty? You’re not alone. Overheating at night is a common challenge that disrupts sleep quality, leaving you feeling tired and groggy. Your bedroom setup—especially your bed and bedding—plays a crucial role in regulating your body temperature for restful sleep.

At Rest Relax, we believe cool, comfortable sleep isn’t just a luxury—it’s essential. Here’s our expert guide to stopping nighttime overheating with cooling beds and breathable bedding.
Why Do We Overheat at Night?
A few key factors can make us too warm while sleeping:
-
Mattress materials like dense traditional memory foam that trap heat.
-
Heavy, non-breathable bedding that insulates rather than ventilates.
-
Room temperature that’s too warm.
-
Personal factors like metabolism, hormones, medications, or health conditions.
While you can’t change everything, you can transform your sleep environment to promote cooler, more restful nights.
Your Bed: The First Line of Defence Against Night Sweats
1. Choose a Breathable Mattress
Traditional memory foam tends to trap heat. Here’s how to upgrade:
-
Spring Mattresses: Pocket sprung mattresses promote airflow through the core, reducing heat buildup.
-
Hybrid Mattresses: Combine spring support with more breathable foam layers.
-
Cooling Technologies: Many mattresses feature gel-infused foams or breathable covers designed for cooler sleep.
2. Pick the Right Bed Frame

A slatted base allows air to circulate under your mattress, dissipating trapped heat. Look for bed frames that feature slatted designs to boost airflow and comfort.

3. Opt for Breathable Duvets
-
Low Tog Rating: Choose a lightweight duvet with a 4.5 tog or less to avoid overheating.
-
Natural Fillings: Cotton, silk, or light wool fillings breathe better than synthetic materials.
-
Cotton Casing: A natural cotton cover promotes airflow.
4. Choose Cooling Pillows and Pillowcases
-
Breathable Fill: Opt for pillows with cooling technologies or natural, breathable fillings.
-
Natural Fibre Pillowcases: Materials like cotton, linen, or bamboo help wick away moisture and allow airflow.
5. Invest in Breathable Bed Sheets
Natural fibre sheets are key:
-
Cotton (Percale or Sateen): Crisp and breathable for hot sleepers.
-
Linen: Excellent moisture-wicking and airflow properties.
-
Bamboo: Naturally temperature-regulating with a soft, silky feel.
Avoid polyester sheets, which trap heat and moisture.
