Anyone who gets overheated during the night might consider a cooling comforter, which can help regulate the body’s temperature.

Research has shown that higher temperatures in the bedroom can contribute to insomnia.

This article discusses the health benefits of temperature regulation during sleep and a range of cooling comforters available online that may help a person stay cool overnight.

A quick look at the 9 best cooling comforters

Temperature regulation may be key for sleep. According to the American Academy of Sleep Medicine, being too hot or cold during the night can interrupt sleep, reducing overall sleep quality.

As the National Institutes of Health (NIH) observe, improving the quality of sleep can provide the following benefits:

  • improved concentration
  • quicker reflexes
  • better problem-solving skills
  • improved mood
  • reduced risk of depression
  • improved immune system function
  • improved cardiovascular health
  • reduced risk of obesity, heart disease, and infections

If a person tends to feel too hot during the night, cooling bedding, such as a comforter, can help draw heat away from the body, potentially improving sleep quality.

When choosing a cooling comforter, it can help to consider the item’s materials, weight, and effects on the environment.

Sustainable materials

Some companies have certification from OEKO-TEX or CertiPUR-US, indicating that specific products are free from harmful chemicals.

OEKO-TEX certification also signifies that the company has ethical working practices and uses sustainable materials.

Allergen-resistant materials

If a person is sensitive to dust, dust mites, pet dander, mold, or other allergens, it may help to choose a comforter that contains materials that may be naturally antimicrobial, such as wool.

Manufacturers sometimes treat other fabrics so that they are resistant to allergens.

Weighted comforters

Weighted blankets are filled with pellets or glass beads and can weigh up to 30 pounds (lb).

They apply pressure that stimulates the parasympathetic nervous system, helping the body enter a state of relaxation instead of engaging in a fight or flight response.

Autistic people and people with certain mental health conditions, such as anxiety, may engage in fight or flight responses more often. In this case, weighted blankets may help foster a sense of calm before sleep.

Others may also benefit from the calming effects of weighted blankets.

One older 2008 study into the effects of deep pressure stimulation during sleep, using weighted blankets, found that participants who used the blankets experienced reduced levels of anxiety and cited the blanket as their preferred method of calming down.

A newer 2020 review agrees that weighted blankets may help to reduce anxiety.

Anyone interested in a weighted blanket should research suitable weights and ensure, for example, that their chosen weight is appropriate for any children who may use the blanket.

A few things a person may wish to consider when purchasing a cooling comforter include:

  • Material: The materials in a cooling comforter should be lightweight and breathable. A person may also wish to consider any allergies and material preferences.
  • Certifications: Some companies may have environmental certifications such as OEKO-TEX and CertiPUR-US. This declares that they follow certain safety and/or environmental regulations.
  • Cost: A person should consider their budget before looking to purchase a comforter. There are various good-quality options on the market at different price ranges.
  • Size: A person should check the dimensions of the product before purchasing to ensure it will fit comfortably on their existing bed.

MNT chooses mattresses, sheets, pillows, and other bedding that meet the following criteria:

  • Certifications: MNT will choose products that have CertiPUR-US or other certifications. This means that the products are low in pollutants and free from heavy metals and volatile organic compounds.
  • Size: MNT chooses products that are available in various sizes.

Various types of cooling bedding are available. Cooling pillows are made from materials that promote temperature regulation, and cooling mattresses are designed to increase airflow and draw heat and moisture from the body.

For a more powerful effect, a person might try a cooling mattress pad, which contains water, air, or cooling foam to moderate temperature throughout the night.

A person’s sleep environment can influence how hot they are while they sleep. A person can consider adjusting air-con settings or using fans to circulate cool air around the room overnight, or invest in cooling bedding.

If a person is experiencing night sweats, they should consider talking to a doctor to determine the cause and discuss possible treatments.

Night sweats can happen even if a person’s sleep environment is cool. Night sweats can also be called sleep hyperhidrosis.

According to the American Osteopathic Association (AOA), a person should consider seeing a doctor for night sweats if:

  • they happen regularly
  • they disturb sleep
  • they cause worry or distress
  • other symptoms are present, such as a fever

The UK National Health Service (NHS) writes that a person should also seek medical advice if they experience night sweats with a cough, diarrhea, and unexplained weight loss.

Below are some of the most frequently asked questions about cooling comforters.

What is the fluffiest cooling comforter?

The fluffiest comforters usually contain down material. These comforters may not be suitable for people with allergies. However, many companies now create down alternatives, which they claim provides the same comfort as down filling.

Why does my down comforter make me sweat?

Down comforters can trap heat rather than allow air to circulate through the material. Down filling can also trap moisture, which may make a person’s sleep environment feel humid.

A person should check the information the company provides regarding the cooling materials and technology it uses in its down comforters. People can choose down comforters that are made with cooling materials, such as cotton. A person can also consider purchasing products from brands that offer sleep trials with its products.

What kind of comforter is best for hot sleepers?

A lightweight comforter made with breathable fabric is the most suitable type of comforter for hot sleepers. Some natural fabrics, such as cotton, can be more breathable than synthetic materials like polyester.

A person should look for a comforter that promotes air flow through the layers, temperature regulation, and wicks moisture from the skin.

A cooling comforter may represent an accessible and relatively affordable way to stay cool throughout the night, regulating heat and humidity levels within the bed.

Temperature regulation can promote unbroken, high-quality sleep, which may, in turn, lead to health benefits such as improved concentration and immune system function.
