Do cooling duvets actually keep you cool?

Many brands advertise a duvet as 'cooling' if it has a lower tog rating or breathable material, like down or microfibre.

Premium brands also use innovative technology, like Stratos, to improve the temperature-regulating capabilities of duvets, such as Simba's Hybrid 3-in-1 Duvet.


We get into this further down.

However, for the most part, these duvets do not provide an instant cooling sensation like having a cold shower or putting an ice pack on your forehead.

Instead, they are designed to prevent overheating so you don't wake up dripping in sweat.

That said, one of our mattress experts, Walter Braun, emphasised the importance of finding a suitable summer duvet.

He said: "About 80% of the overall temperature in bed is determined by the duvet. If you overheat or freeze in bed, you should reconsider your choice of duvet. Depending on which duvet you use, it may not be suitable for your new mattress."

How do cooling duvets work?

Even the best duvet for sweaty sleepers might not provide an instant cold sensation, but it can help to regulate your temperature at night.

Here are a few features that help cooling duvets do their job.

Cooling technology

Some of the best cooling duvets (UK) utilise patented thermo-regulating fabrics [1], adapting to your body temperature so you stay cool.

Advanced technology allows the duvet to adjust its heat absorption [2] and dissipation properties, creating a balanced sleeping environment.

You could even have a duvet that takes cues from NASA spacesuits. 🧑‍🚀

Certain cooling duvets incorporate Stratos, a material originally developed by NASA for use in spacesuits.

This incredible material can absorb excess body heat and then release it back to you if you start feeling chilly.

If it works for astronauts, it could work for you!

This space-tech-inspired innovation makes the duvet highly versatile and suitable for year-round use regardless of the weather.

Our recommended Simba duvet uses this space-inspired technology!


Lightweight tog

One of the key features of cooling duvets is their lightweight tog rating.

Tog refers to the measure of thermal resistance in a duvet, determining its warmth level. 🔥

Cooling duvets are typically designed with a lower tog rating, allowing for enhanced breathability and heat dissipation.

temperature tog ratings
A lower tog indicates a cooler duvet.

The lower tog also provides a lightweight and comfortable feel, giving you a more refreshing sleep.

We recommend the Silentnight Cooler Summer duvet with a 4.5 tog filling if you're an extra hot sleeper.


Breathable and moisture-wicking capabilities

Both natural and manmade cooling duvets offer excellent breathability.

But how exactly do fabrics breathe? 🫁

Well, it's not in the human sense, that's for sure!

When it comes to fabrics, breathability is about how well air circulates throughout the material.

A breathable duvet has better air circulation, helping to keep your duvet fresh throughout the night.

Moisture-wicking capabilities are also important for those who sweat a lot at night.

This refers to the fabric's ability to allow water vapour to pass through the material and evaporate from the other side.

It keeps your skin dry and your body temperature down while you're under your cooling duvet.

Get a good night's rest in a dry environment that wicks away your sweat.

Some natural materials, such as cotton, silk and bamboo, are known for their breathability and moisture-wicking capabilities, while other natural materials, like down and wool, have great thermal properties.

Equally, manmade materials like microfibre often have superior cooling technology that promotes airflow to keep your skin dry while sleeping.

Ultimately, the choice between natural and manmade materials comes down to personal preference and budget.


If you're a sweaty sleeper, a machine-washable cooling duvet cover and insert is an absolute essential. 🧺

Luckily, many cool duvet covers and inserts are designed to be easily washable, so you can keep them fresh and hygienic.

Bear in mind you should only wash your cool duvet once or twice a year unless you spill something on it.

Before washing, be sure to check the care instructions provided by the manufacturer to ensure you're following the recommended cleaning process.

Annual washing eliminates sweat and odour and helps maintain the duvet's cooling properties over time.

All of our recommended cool duvets are machine-washable, so you can keep them fresh over the summer.

What is the best cooling duvet material?

The composition of your duvet can make a huge difference to its cooling properties.

Here are some of the most popular materials for the insert and cover of the best summer duvets.


Some of the best cooling duvet covers are made from microfibre.

It's popular because of its super soft and smooth texture.

It is a synthetic fabric made from finely woven polyester fibres, which create a lightweight and breathable duvet cover.

Microfibre cool duvet covers are known for their excellent moisture-wicking properties, helping you keep cool and dry throughout the night.

Additionally, microfibre is generally easy to clean and maintain and has anti-allergy properties.


Hollowfibre makes one of the best temperature regulating duvet inserts.

It is a synthetic filling material with great breathability and temperature regulation.

It consists of hollow polyester fibres that trap air, creating a lightweight, insulating layer.

pros and cons of hollowfibre duvets
Weigh up the pros and cons to decide if hollowfibre is right for you.

Hollowfibre duvet fillings are known for maintaining a comfortable sleeping temperature by allowing excess heat to escape while retaining warmth when needed.

Hollowfibre duvets are often hypoallergenic and easy to care for, making them a practical choice for those with specific needs.

They are also one of the cheapest duvet materials, which is ideal for those on a budget.

We recommend the Silentnight Cooler Summer Duvet if you want an anti-allergy or goose-down alternative duvet made from hollowfibre.



Cotton is a classic and widely beloved fabric for the best breathable duvet covers.

Cotton allows air to circulate and prevents heat buildup so you can sleep in a cool sleep environment.

If you’re looking for a cotton cover to go over your duvet, make sure it is 100% cotton and not cotton sateen.

Sateen has a thicker weave and is better for the cooler months.

Cotton covers are highly absorbent, effectively wicking away moisture and providing a comfortable feel against the skin.

Moreover, cotton is a natural and hypoallergenic material, making it an excellent choice for individuals with sensitive skin or allergies.

The Simba Hybrid 3-in-1 is made from ultra-breathable cotton alongside Stratos technology and Modal.



Polyester is another commonly used synthetic filling material in a cosy, cool duvet.

It is known for its affordability, durability, and easy maintenance.

Polyester duvet fillings provide a lightweight, hypoallergenic option, allowing for adequate air circulation and effective temperature regulation.

While polyester may not offer the same level of breathability as natural materials, it is a budget-friendly choice that can still provide a comfortable sleep experience.

Polyester is not our first choice for hot sleepers.

Feather or down duvet

Down and feather fillings are sourced from birds, typically ducks or geese. 🦆

They are highly regarded for their natural insulation properties and breathability.

Down [3] refers to the soft clusters found beneath a bird's feathers, while feather fillings come from the outer feathers.

Down and feather make some of the best duvet filling for hot sleepers.

These fillings create a warm yet breathable layer that adapts to your body temperature, keeping you cosy without overheating.

However, it's important to note that some individuals may have allergies or sensitivities to these natural fillings, so consider this when selecting.

If you're looking for a luxurious down duvet, we recommend the Brooke + Wilde Sleep Cavendish Four Seasons Duvet.

Other bedding to keep you cool

The best cooling duvet (UK) is only one step to a comfortable night’s sleep in the summer months.

There are cool mattresses, pillowcases, bed sheets and much more to think of, too.

Cooling duvet covers UK

If you already have a duvet that you love but still want to lower your temperature, a temperature regulating duvet cover is a game-changer.

These covers are specifically designed with breathable fabrics that promote air circulation and prevent heat buildup. 💨

Look for duvet covers made from materials like bamboo, cotton, linen or eucalyptus fibres, known for their excellent moisture-wicking properties and breathability.

Choose a cooling duvet set with a higher thread count for a more luxurious feel.

Investing in a cool duvet cover can transform your regular duvet into a cooling oasis, providing a more refreshing night’s sleep during the summer.

We recommend Panda bedding and Aeyla Eucalyptus bedding for hot sleepers and summer nights.

Cooling mattress pad

Cooling mattress toppers are a fantastic addition to your bedding ensemble, especially during hot summer nights.🌜

However, those looking for a significant difference in their sleeping temperature should consider a cooling mattress pad instead.

These pads are typically made with advanced cooling technologies or materials that actively draw heat away from your body.

They work by dissipating excess heat and regulating your body temperature, ensuring you stay cool and comfortable. 🌡️

Try out a cooling mattress pad to stay cool at night.

Cooling mattress pads come in various forms, including gel-infused pads or those with moisture-wicking properties.

You can find them in all different sizes, from super-king to singles.

Placing a cooling mattress pad directly on top of your mattress creates a cool barrier between your body and the heat-retaining surface.

We recommend the Amazon FFTT Pro Cooling Mattress Pad for a night of sweat-free sleep.

Cool mattresses

If you're a hot sleeper, you could also invest in a cool mattress, which will make a big difference to your overall sleeping temperature.

Stay clear of memory foam, and opt for mattresses with pocket springs or natural materials which are more breathable.

Cooling pillows

While we often focus on keeping our bodies cool, we must not neglect our heads during the night.

Cooling pillows are designed to support and refresh your head and neck while keeping you cool.

pillows with cooling gel
Keep your head and neck icy cool at night.

These pillows often incorporate cooling gel or breathable materials that promote air circulation and prevent heat accumulation.

They are typically made from memory foam, which contours to your head and neck while offering pressure relief.

With a cooling pillow, you can enjoy the benefits of temperature regulation, allowing you to stay cool and sleep soundly throughout the summer nights.

We recommend the Kally Cooling Pillow to keep your head and neck dry all night long.

So, is there a duvet that keeps you cool?

When it comes to the best duvet for hot sleepers UK, our recommended cooling duvets can be a major lifesaver, especially if you’re going through menopause or struggling with the summer heat.

With cooling technology and breathable natural fabrics, these duvets are designed to regulate your temperature at night and help you get a better night's sleep.

If you're still struggling with being too hot at night, we recommend adding a cooling gel mattress pad and pillow.
