Choosing a comforter specifically designed for hot sleepers may help keep people cool when sleeping.

Sleeping in hot environments can have negative effects on a person’s sleep quality. For example, having a high body temperature while sleeping can contribute to insomnia, which may negatively impact a person’s day-to-day life.

This article explains which types of comforters may help people stay cool during the night.

A comforter is different from a duvet.

A duvet is a plain insert filled with down or synthetic fibers and used inside a duvet cover. This means that people can change the duvet and duvet covers when they want to, such as according to the season. There are varying duvet thicknesses to suit the changing temperatures throughout the year.

A comforter, on the other hand, is made out of more durable fabric than a duvet, as it is not used inside a cover. Comforters contain down or synthetic fibers. They offer an advantage over duvets in that they do not move around inside a duvet cover since a cover is not necessary.

However, comforters can be harder to wash and will likely become less soft over time.

The following are some features to look for when choosing a comforter for hot sleepers.

Outlast technology

Outlast is a brand of phase change material (PCM) that experts originally developed for NASA. It absorbs, stores, and releases heat to regulate temperature. It is common in fabrics that continually regulate a person’s temperature.

Outlast technology does not wick moisture away from the skin as a person sweats. Instead, it works to prevent sweating by controlling a person’s temperature before they become too hot and begin to sweat.

For night sweats, specialist sheets may help. Learn more about them here.

Sustainable fabrics

Choosing a comforter made from sustainable fabrics or made through responsible production methods means that it will have little negative impact on the environment.

Tencel fabric is one sustainable fabric option that manufacturers often use in comforters.

Eco-friendly certifications

There are a range of certifications that indicate that a product has been sustainably produced with safe materials.

These certifications include OEKO-TEX, which ensures that products have been made without harmful substances or unethical work practices or conditions and that the manufacturers have produced them in an environmentally sustainable way.

Please note that the writer of this article has not tried any of these products. All information presented here is purely research-based.

Slumber Cloud Tencel Cumulus Comforter

This comforter uses two fabrics to help regulate temperature during sleep.

Tencel-branded fabric contains lyocell and modal fibers made from sustainable wood sources. It is known for being very soft and breathable. Tencel fabric is good for absorbing moisture from the skin through the structure of the fabric.

This comforter also uses Outlast technology to enhance its cooling effect on the user. The Outlast PCM absorbs, stores, and releases a person’s body heat as needed during the night.

The combination of Tencel and Outlast fabric means that this comforter should prevent sweating, but the Tencel fabric wicks away moisture if a person does happen to sweat overnight.

Casper Humidity Fighting Duvet

This product can function as either a duvet or a comforter. It is made from a 100% cotton outer layer and an extra Merino wool layer that naturally offers moisture and temperature regulation.

According to Casper, Merino wool is finer and lighter than regular wool, so this duvet is less likely to make a person hot if they are sleeping in a warm environment.

This duvet is OEKO-TEX certified, ensuring that it has not been made with harmful substances and that it is suitable for children and babies.

The filling is ethically sourced down, which means that this comforter may not be suitable for people with allergies.

Buffy Breeze Comforter

This comforter contains 100% eucalyptus fabric in the outer layer and the filling. Eucalyptus fabric is a type of Tencel material that offers moisture-absorbing and temperature-regulating properties.

The company recommend it for hot sleepers and those sleeping in hot climates. Eucalyptus fibers are also naturally resistant to dust, mites, and mold.

The Buffy Breeze Comforter is OEKO-TEX certified, which means that it has been made sustainably and without any harmful substances.

Comfort Classics Coolmax Comforter

This comforter is an affordable option.

It uses patented Coolmax technology, which has moisture management technology built into the yarn. The Coolmax fibers draw moisture away from the body to help sleepers maintain a comfortable temperature.

This comforter may also keep a person dry if they sweat. The fabric is breathable and encourages airflow throughout the comforter.

The Comfort Classics Coolmax Comforter is available for purchase online.

Frankenmuth Woolen Mill Wool Filled Comforter

This comforter uses the naturally insulating and temperature-controlling properties of wool.

The outer layer is made from 100% organic muslin, and air pockets within the wool fibers inside match a person’s body temperature beneath.

The company claim that this comforter is also suitable for people living with fibromyalgia and arthritis. This is because wool is a supportive material, and its temperature-regulating properties help keep joints appropriately warm or cool. However, this claim has no supporting research.

There are other products a person can use to keep cool during the night if they do not want to use a cooling comforter.

The sections below will look at these options in more detail.

Cooling pads

Cooling pads are mattress toppers that are made out of cooling materials or use active cooling systems. Some affordable options are made with gel-infused memory foam, which absorbs heat and draws it away from the body.

More expensive cooling pads include toppers that connect to remote controlled cooling systems, which use water or air to cool the topper to a person’s ideal temperature.

Cooling sheets

Cooling sheets use materials that are breathable to help regulate a person’s temperature while they sleep.

Linen, Tencel, cotton, and eucalyptus are all popular materials in cooling sheets, as they may draw moisture and heat away from the body.

Cooling mattresses

Cooling mattresses often use specially designed foam layers to enhance breathability throughout the mattress. Graphite, copper, or gel-infused fibers also draw heat and moisture away from the body.

A person’s body temperature responds to the circadian rhythms that control sleep, and body temperature tends to drop before a person sleeps.

If a person warms up before they sleep, such by taking a hot bath or shower, the body’s rapid cooling afterward can help induce sleep.

A person may also feel hot at night because of the room’s temperature or due to the materials in their mattress or bedding.

Feeling too hot during the night is different from experiencing night sweats, which is a potential symptom of an underlying condition. A person experiencing night sweats should contact a doctor to find out the cause and start the appropriate treatment.

Feeling too hot during the night can disrupt a person’s sleep. Choosing cooling comforters, duvets, mattresses, or mattress toppers may help prevent overheating and promote restful sleep.

Cooling comforters help the body stay cool through specialist materials or dedicated technology.
