How do cooling duvets work?
When you're a hot sleeper, finding the right bedding is crucial for a comfortable night's sleep.
Many brands market duvets as "cooling" based solely on a lower tog rating or general breathable materials.
However, true cooling duvets go a step further - they are specifically designed to actively regulate your temperature and prevent overheating, rather than providing an instant cold sensation.
Innovative cooling technologies
The most advanced temperature-regulating duvets UK utilise cutting-edge technologies to maintain your ideal sleep temperature.
Some incorporate patented thermo-regulating fabrics [1] that adapt to your body's temperature - this advanced technology allows the duvet to adjust its heat absorption and dissipation properties [2], ensuring a balanced sleeping environment.
A prime example is Stratos, a material originally developed by NASA for spacesuits.
This incredible innovation can absorb excess body heat when you're warm and release it back if you start to feel chilly, making the duvet highly versatile for consistent comfort.
Brands like Simba incorporate this space-inspired technology into their best cooling duvet offerings, including the Simba Hybrid duvet and the Simba Hybrid 3-in-1 duvet.
Breathable & moisture-wicking properties
Beyond specific technologies, the inherent properties of certain materials are vital for a cool duvet.
- Excellent breathability ensures that air circulates effectively through the fabric, preventing heat from getting trapped.
- Equally important are moisture-wicking capabilities. This refers to the fabric's ability to draw sweat away from your skin and allow it to evaporate quickly from the material's surface.
This process keeps your skin dry and your body temperature down, ensuring you stay comfortable under your cooling quilt.

Best cooling duvet materials for hot sleepers
The composition of your duvet is paramount to its cooling performance.
For hot sleepers, look for materials specifically chosen for their heat-dissipating and moisture-managing properties.
Here are some of the best cooling duvet materials for both duvet inserts and covers:
- Tencel / Lyocell: Derived from wood pulp, Tencel is renowned for its exceptional breathability and superior moisture-wicking capabilities. Its smooth fibres help regulate temperature by absorbing and releasing moisture efficiently, keeping you dry and cool.
- Bamboo: Naturally thermo-regulating, bamboo fibres are incredibly breathable and have excellent moisture-wicking properties, absorbing more moisture than cotton. This helps hot sleepers stay dry and cool throughout the night. Take a look at our guide on the best bamboo duvets.
- Silk: This is a natural fibre with impressive temperature-regulating properties. Silk is highly breathable and can wick away moisture effectively, creating a cool and dry sleeping environment without feeling clammy. Silk bedding is very popular.
- Cotton: A classic choice, 100% cotton is naturally breathable and allows air to circulate, preventing heat build-up. Its moisture-absorbent qualities help wick away sweat, making it a reliable option for a cooling duvet insert cover. Look for percale weaves for an even crisper, cooler feel.
- Down & feather: These natural fillings are highly breathable, allowing air to circulate and excess heat to escape. They adapt to your body temperature, providing warmth without causing overheating, making them surprisingly suitable for hot sleepers when used in a lighter fill. Eiderdown duvets are very popular options.
- Phase Change Materials (PCMs): Found in advanced duvets (like those utilising Stratos or Outlast® technology), PCMs absorb, store, and release heat to maintain a consistent microclimate. This active thermoregulation makes them ideal for temperature-regulating duvets in the UK.
- Hollowfibre: A synthetic filling known for trapping air due to its hollow strands, creating a lightweight and breathable layer. While offering good air circulation, its primary benefit is lightness and affordability, which can contribute to a cooler feel for some, but it may not offer the same active cooling as PCMs or natural fibres like bamboo.
- Microfibre: Made from finely woven polyester fibres, microfibre can be soft and lightweight. Its cooling properties for hot sleepers depend heavily on specific weaves or treatments that enhance air circulation and moisture-wicking; otherwise, its primary benefit is often softness and ease of care.
The best duvets for hot sleepers will often combine one or more of these innovative materials or technologies to deliver a truly refreshing night's sleep. ❄️
What other bedding keeps hot sleepers cool?
While finding the best cooling duvet is paramount, it's just one piece of the puzzle for consistently comfortable sleep.
For ultimate temperature regulation, consider complementing your duvet with other cooling bedding essentials:
- Cool mattresses: For a comprehensive upgrade, choose cool mattresses with breathable designs like pocket springs or natural materials.
- Cooling duvet covers: Transform your existing duvet with a temperature-regulating duvet cover made from breathable, moisture-wicking fabrics like bamboo or Tencel. We'd recommend checking out Panda bedding for some cooling options.
- Cooling mattress pads: These actively draw heat away, using advanced technologies or materials to create a cool barrier between you and your mattress.
- Cooling mattress toppers: Add an extra layer of comfort with cooling mattress toppers featuring breathable materials or gentle temperature regulation.
- Cooling pillows: Keep your head and neck refreshed with cooling pillows featuring gel layers or aerated, breathable materials.
These additional sleep essentials work in harmony to create an optimal, consistently cool sleep environment for any hot sleeper.

Frequently asked questions
-
Do cooling duvets actually keep you cool?
Yes, cooling duvets are designed to prevent overheating and actively regulate your body temperature, rather than providing an instant cold sensation.
They achieve this through advanced materials and innovative technologies that absorb and dissipate heat, helping hot sleepers avoid night sweats.
-
Why does my duvet make me sweat at night?
Your duvet might be trapping heat and restricting airflow due to its material composition (e.g., some synthetics) or a high tog rating that provides too much insulation.
Choosing a duvet with breathable fabrics and active temperature regulation is crucial for preventing overheating.
-
What is the best cool duvet during menopause?
For those experiencing hot flushes or night sweats due to menopause, the best cool duvet will actively wick away moisture and regulate temperature.
Look for duvets made with advanced cooling technologies and highly breathable materials like wool, silk, or bamboo to provide relief and promote restful sleep.
-
What tog rating is best for a cooling duvet?
While a lower tog rating (typically below 7) can certainly aid in coolness by offering less insulation, the most effective cooling duvets integrate advanced temperature-regulating technologies that work regardless of the specific tog.
For very hot sleepers, a lower tog combined with active cooling features offers optimal comfort.
-
How do I stay cool while sleeping?
Beyond choosing a cooling duvet, focus on your sleep environment.
Keep your bedroom cool and well-ventilated, use lightweight and breathable sleepwear, and avoid triggers like alcohol or caffeine before bed.
Complementary cooling bedding like mattress pads and pillows can also significantly help.
