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

Studies have shown that higher temperatures in the bedroom can contribute to insomnia.

Below, learn about the health benefits of temperature regulation during sleep and a range of cooling comforters that may help and are available for purchase online.

A comforter has an outer shell made from any of a range of fabrics, including cotton. This is filled with down or synthetic material.

Comforters come in different thicknesses and weights, like duvets. The two differ because a duvet is meant to be inserted into a cover. A comforter does not need a cover and is made of more durable material.

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 and heart disease

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 study, from 2008, 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.

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

Below, find top options tailored to various needs.

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 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.
