The Truth Behind Night Sweats

Night sweats are described as excessive sweating during sleep, commonly associated with fevers and other serious medical conditions. Medically, this could be considered a symptom of bigger underlying problems but that’s not always the case. Most of the time, night sweats are caused by using duvet covers that are too warm for the season and the room.

Speaking from a medical point of view, night sweats (as a symptom of something more serious) can be caused by the following:

  • Fever
  • Anxiety
  • Menopause
  • Diarrhea
  • Medication

These are just a few of the many things that can cause it. If you’re unsure about the reason behind your night sweats, it’s better safe than sorry. If a trip to the doctor is not doable at the moment, remain highly aware of your body until you finally seek professional help.

Duvet Buying Guide

Not all duvets are made equal. Sometimes, even duvets on the expensive side of the spectrum vary in effectiveness. To find a duvet that works for you, it's best to trust the facts rather than the advertising. There are a few key markers to look for in a good duvet suitable for night sweats. Follow this guide to know which will work best for you!

TOG Rating

The most important factor in your duvet is the TOG rating. This stands for Thermal Overall Grade, which determines the warmth of the duvet, regardless of its thickness. TOG ratings from 1 – 4.5 are on the cooling side, while higher values are much warmer.

Duvet Filling

The next to consider is the duvet filling. Natural fillings are better for cooling since synthetic fibers tend to run warm and retain heat. That said, synthetic fillings are more affordable, with microfiber and hollow-fiber-filled duvets as better synthetic options.

Duvet Covers

The fabric used for duvet covers (also called ticking) plays an important role in ventilation. The most breathable fillings could still be blocked if the cover fabric doesn’t regulate temperature. The best options use cotton or linen since these help air circulate.

Other factors such as duvet size, price, design, and cleaning instructions are all subjective. Natural fillings tend to be pricier but these perform great. Synthetic fillings are more affordable, however, these don’t allow much cooling to happen.

Check Out Some Of The Best Duvet Filling For Night Sweats

1. Silentnight Cooler Summer Duvet

[amazon box=”B00TQWMVV4″]


  • 4.5 TOG
  • Made for the summer
  • 100% Recycled lightweight fiber
  • Hypoallergenic duvet filling
  • Microfiber cover that's moisture-absorbent
  • Machine washable
  • Five-year warranty


  • Filling tends moves around with fitful sleepers
  • Synthetic materials aren’t optimized for cooling

Silentnight is the go-to for all sleep needs. This is no different for their Cooler Summer Duvet.

This duvet has a recycled lightweight fiber filling encased in a soft microfiber cover, with a 4.5 TOG. This means it's cool but not enough to be cold. However, this filling tends to move around, especially for fitful sleepers. On the bright side, this is hypoallergenic, keeping you safe from dust mites and allergens.

This duvet cover has a point of weakness as it's not the very best at ventilation. That said, it has the advantage of being moisture absorbent, which is good for any sweating. Since it absorbs sweat, the duvet is machine-washable for safety and hygiene purposes.

This might be amazing for those who prioritize preserving nature. Since it uses recycled fiber filling, resources are saved with this. The way this duvet feels is also reminiscent of true down duvets, in both coziness and comfort, but at only a fraction of the cost.

2. Night Comfort Summer Breeze Duvet

[amazon box=”B07F58NL7X”]


  • 1.5 TOG
  • Made for the summer
  • Hollowfibre filling
  • Hypoallergenic
  • Soft-touch cover
  • Machine washable
  • Tumble dryer safe
  • Quilted to lessen filling movement


  • Retains heat
  • Poor packaging

The Night Comfort Summer Breeze Duvet is made for the warm season for comfortable, uninterrupted sleep.

This duvet is extremely cozy and has a 1.5 TOG rating, which is rare to find in the shops. This is filled with hollowfibre, a synthetic hypoallergenic down alternative. Unfortunately, it tends to retain heat on extremely warm summer nights. Amazingly, it’s still thick despite its cooling nature.

This had a very soft quilted microfiber cover, which helps the filling stay in place. Thankfully, this is also machine washable and dryer safe.

That said, be warned about the hollow-fiber filling. It has difficulty ventilating air and tends to retain more heat than a natural filling duvet. This also comes in poor packaging, which might cause distrust of the product.

Even so, this could be helpful for those who are looking for versatile low TOG duvets. The 1.5 TOG rating makes it suitable for cooling in the summer, while the synthetic filling could also work in your favor while lounging on a couch in winter.

3. Slumberdown Cool Summer Nights Duvet

[amazon box=”B07XFR2RH7″]


  • 4.5 TOG
  • Made for the summer
  • Hollowfibre filling
  • Non-allergenic duvet
  • Soft-touch cover
  • Machine washable
  • Tumble dryer safe
  • Lightweight
  • Made in the UK


  • Filling clumps up
  • Synthetic filling is less effective at ventilation
  • Lacks dust mite protection

The Slumberdown Cool Summer Nights Duvet is a lightweight quilt that cools without irritating you on warm nights.

This is a 4.5 TOG non-allergenic duvet, meaning it's treated to prevent most allergies but not dust mites. It’s made of a hollowfibre filling within a soft-touch cover, giving it a luxurious and plush impression.

Being lightweight likewise helps it keep cool, while the soft-touch cover feels great on the skin during sleep. To keep it effortlessly clean, this is also machine washable and dryer safe.

However, the filling clumps up together, leading to discomfort. The synthetic filling could also trap heat during particularly warm nights, which won’t do much for night sweats.

This could be great if you’re looking for a thin and lightweight duvet that feels great on warm nights. It's also made in the UK, which is a plus for production concerns.

4. Snuggledown Hungarian Goose Down Duvet

[amazon box=”B01M1E6AMB”]


  • 4.5 TOG
  • Breathable summer duvet
  • Hungarian goose down and feather filling
  • Soft cotton cover
  • 300 thread count
  • Machine washable
  • Lightweight duvet
  • Made in the UK
  • Box construction for filling


  • Not good for dust mite allergies
  • Premium price

The Snuggledown Hungarian Goose Down Duvet is a naturally-filled luxurious duvet made to cool during warm nights.

This 4.5 TOG duvet is filled with a goose down and feather mix. In case you weren’t aware, down refers to the fluffy feathers in a bird’s undercoat. This also uses a very 300 thread count soft cotton ticking, helping the duvet breathe.

It comes at a premium price since down feathers don’t usually come cheap. This is the optimal combination of materials to cool at night and absorb moisture. Luckily, this duvet is machine washable and won’t require professional cleaning.

Unfortunately, there’s a common misconception that most people are allergic to down but this that’s actually quite rare. Somewhat more common are dust mite allergies, which this duvet doesn’t protect against.

This lightweight duvet was made for optimal relief during warm and humid nights. For luxury sleep experiences instead of constant night sweats, this might be the best way to go.

It has a 4.5 TOG rating, with a premium hypoallergenic cotton filling. What’s unique about this is its dual-sided cover. The warm side uses Egyptian cotton while the other side uses a Japanese cooling fiber ticking to stay comfy.

Furthermore, this is Oeko-TEX certified, meaning it’s tested and contains no harmful chemicals. The machine-washable duvet can also absorb moisture from sweat.

The two sides mean you can get your money’s worth from it, especially considering it approximately costs twice the average duvet. Sadly, this is only compatible with single and double beds.

This could be an amazing duvet for you if you want something to serve many purposes. Since this has two temperature sides, there’s more chance to get some use out of it, regardless of the season. It’s also absorbent and helps with the more pesky night sweats. Thanks to its certification, this has become an even safer option.

Final Thoughts

It’s clear these duvets each have strengths and weaknesses but one duvet outshined the rest.
