For some people, using a quality blanket that promotes heating or cooling can enable comfortable and continuous sleep.

A person’s sleep environment is an important factor in getting good quality sleep. Using heating and cooling blankets can help create an optimal sleep environment for hot or cold sleepers.

This article discusses the health benefits and potential risks of using heating and cooling blankets, looks at 5 of the best options available online, and some alternatives a person can consider. It also covers some frequently asked questions about heating and cooling blankets.

The Centers for Disease Control and Prevention (CDC) recommend that adults get 7 hours of sleep each night. Younger children and teenagers tend to need more than this.

According to the American Academy of Sleep Medicine, good sleep hygiene is important in getting good quality sleep. To achieve the best sleep, it recommends that people:

  • Limit or avoid alcohol consumption before bed.
  • Do not eat large, heavy meals before bed.
  • Keep a consistent sleep schedule, even on weekends and vacations.
  • Avoid caffeine consumption later in the afternoon.
  • Get out of bed if they do not fall asleep within 20 minutes.
  • Use the bed for sex and sleep purposes only.
  • Limit fluid consumption before bedtime.
  • Avoid going to bed unless they are tired.
  • Create a relaxing routine before bed.
  • Create a relaxing, quiet, and dark bedroom.
  • Limit exposure to bright lights in the evenings.
  • Avoid electronic devices for 30 minutes leading up to bedtime.
  • Try to keep the room at a comfortable temperature.

Temperature plays a key role in overall sleep quality and duration. According to one 2019 study, researchers found an association between poorer quality sleep and temperature. Specifically, they found that higher environmental temperatures negatively affected:

  • sleep adequacy
  • sleep calmness
  • falling asleep
  • sleep satisfaction

In another study, researchers found that heat and cold exposure in real-world settings can negatively impact a person’s sleep. They found excessive heat is more likely to affect sleep quality, while excessive cold temperatures may affect cardiac autonomic response without interrupting sleep.

In summary, people should try to sleep in an environment that is neither too hot nor too cold.

A heating blanket may help people who feel cold at night reach an ideal temperature. Using a cooling blanket may help people feel comfortable while reducing sleeping temperature.

A heating blanket, or an electric blanket, uses internal heat coils to provide additional heat to sleepers. Typically, a person will plug in the heating blanket and set the temperature to the desired level. Many devices also have automatic shutoffs to help prevent fires.

A cooling blanket can help warm sleepers, and people in warm environments feel comfortable without trapping in extra heat. Cooling blankets usually consist of breathable materials that help release heat.

There have been no studies into the effectiveness of cooling blankets for sleep for commercial use.

In some cases, a blanket may offer a climate control feature. These blankets offer heating and cooling effects based on the user’s needs.

When selecting a blanket, a person should consider their needs and preferences. For example, they can consider the following questions:

  • Is my sleep environment hot or cold?
  • Do I regularly sleep hot?
  • Do I have a sleep partner?

A person may also want to consider:

  • the materials used to make the blanket, including the quality, type of material, and effects on allergies
  • features such as automatic shutoff or dual side controls
  • price
  • reviews

Every person will vary in terms of their preferences.

  • 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.

A person can consider the following factors when choosing a heating or cooling blanket:

  • Heating or cooling options: A person should assess their needs when looking for a new heating or cooling blanket and consider whether they regularly sleep hot or cold. Cooling blankets are suitable for those who sleep hot or live in warm climates. Heating blankets may be best for colder weather and those needing extra warmth when sleeping.
  • Material: A person should consider how the material of their chosen heating or cooling blanket will affect their sleep in terms of temperature and comfort. For instance, some materials are more breathable than others, while others are best for insulating sleepers and keeping them warm. Some companies may use materials from sustainable sources or hold certifications that state that their products are made with industry best practices or without harmful chemicals.
  • Price: A person can consider how the features they would like in a blanket suit their budget.
  • Safety: For heating blankets, a person should consider the safety of the electrical elements. For instance, they should consider options with automatic shutoff features to prevent a person from getting too hot overnight, sustaining burns, and reduce the risk of fire and the blanket overheating. A person should get their heating blanket checked for electrical safety regularly.
  • Size: Some companies offer blankets in a range of sizes. A person should consider which size works best for their bed and if one or two people will be using the blanket.

Alternatives can vary based on the user’s needs. For example, using a cooling mattress is an option for people who want to have cooling effects year-round. Learn more about them here.

Hot sleepers who do not want to replace their mattress may wish to consider using a cooling mattress pad or cooling sheets. A cooling comforter is a good option for people who sleep hot but still want comfort.

People who want extra heat can layer blankets and remove them as they warm up. Another option is to use a hot water bottle.

Climate control system

Couples may wish to consider using a climate control system for their bed. Similar to hospital beds equipped with airflow, climate control systems pump warm or cold air under the covers.

For example, BedJet Cooling, Heating & Climate Control allows couples to pump in warm or cool air based on their preferences to help them sleep better. This product is available for purchase online.

Below are some of the top frequently asked questions about heating and cooling blankets.

Can you wash a cooling blanket?

A person may wash their cooling blanket. Each blanket will have different washing instructions, so a person should check before washing it for the first time.

What blanket material is the coolest?

The type of blanket material that feels the coolest can vary between individuals. Bamboo and viscose-based fibers are good materials for absorbing moisture.

Are cooling blankets good for night sweats?

Research into whether cooling blankets are useful for night sweats is limited. However, cooling blankets may help absorb moisture and reduce a person’s sleeping temperature.

If a person is experiencing night sweats, they should talk to a doctor to determine the cause and the best treatment for them.

Temperature plays a key role in helping a person fall asleep and stay asleep.

Cooling blankets can help hot sleepers feel comfortable without trapping in too much heat. A heating blanket can help people who sleep cold feel warmer and help improve their sleep quality.

A person should decide which type of blanket makes the most sense for their needs and consider the quality of materials. Also, they should try to compare online reviews from different sources for an accurate view of a product’s pros and cons.
