Best Cooling Pillows

Many people know the feeling of turning their pillow over to the “cool side” in the middle of the night. Traditional pillows often retain heat and feel warm against the sleeper’s face. Flipping the pillow over to the other side feels cooler, albeit briefly. Hot sleepers especially may be wondering if there is a cooling pillow that provides that feeling consistently throughout the night.

Sleeping hot can result in sweating, overheating, and general discomfort. It can also interrupt sleep and cause daytime fatigue. Temperature affects sleep quality, and there are plenty of factors to consider when creating a comfortable sleep environment. The mattress, pillows, and bedding all play a role. A cooling pillow can help people sleep comfortably by regulating temperature and dissipating heat.

We’ll cover our top picks for the best cooling pillows and what to look for when shopping. We break down what a cooling pillow is and its pros and cons for sleepers. You’ll also find helpful tips for sleeping cool.

What is a Cooling Pillow?

Choosing the right pillow is just one component of creating a cooling sleep environment. There is a direct relationship between temperature and sleep, and your bedroom should be set to a comfortable temperature to improve sleep quality. Colder room temperatures facilitate better sleep, and many studies recommend keeping the bedroom around 65 degrees Fahrenheit.

Your body has a circadian rhythm that lowers your body temperature when it is time to prepare for sleep. A hot room can increase wakefulness. This disrupts the body’s natural sleep-wake cycle and results in poor quality sleep. Some people sleep hotter than others. This can make it harder to fall asleep. Cooling bedding can provide comfort and encourage restful sleep.

How to Choose a Cooling Pillow

There are many factors to consider when choosing a cooling pillow, including its cooling properties and the quality of materials used. Every sleeper has unique needs, but there are common elements that can help each person determine if a pillow is right for them. These include price, loft, firmness level, and pressure relief. Keep in mind your sleeping position, weight, and personal preferences when shopping for a cooling pillow.

What to Consider When Purchasing a Cooling Pillow

When purchasing a cooling pillow, these are the top things to focus on. A cooling pillow draws heat away from the body, and certain materials do this better than others. That being said, each person is different and what works for one may not work for another.

In addition to regulating temperature and providing a comfortable sleep environment, a cooling pillow may also relieve pressure and provide ample support for the head, neck, and shoulders. While the focus of this guide is a pillow’s cooling properties, there are additional factors that determine if a pillow is a good purchase or not. Shoppers should consider what type of pillow they want, and what is most important to them in addition to cooling properties.

• Cooling Properties: The cooling properties of a pillow determine how well it regulates temperature, dissipates heat, and keeps you cool throughout the night. Most cooling pillows have passive cooling properties, meaning they are constructed with materials that either encourage airflow or draw heat away from the body. Gel, copper, phase-change materials, and graphite are all conductive materials that pull heat away and dissipate it. Moisture-wicking materials like wool, cotton, and bamboo are helpful for hot sleepers prone to sweating throughout the night. These breathable materials also circulate air and prevent heat retention. For shoppers, it is important to focus on the materials and construction of the pillow over any marketing buzz.
• Sleeping Position: What position you sleep in each night determines the firmness and loft you should look for in a pillow. Side sleepers need a pillow with a higher loft that fills the space between the neck and shoulders. This helps keep the spine aligned and reduces pressure. Back sleepers maintain a neutral posture, but need a pillow that keeps their head level and not tilted too far forward or back. Stomach sleepers prefer thinner pillows that keep their head and neck at a comfortable angle.
• Price: Pillows are available at a wide range of price points, so setting a budget before shopping can be helpful. Keep in mind that some materials are more expensive than others. A high-quality cooling pillow can range between $75 to $150 or more, which is more expensive than the average pillow.
• Pressure Relief: A pillow provides additional support and relieves pressure and tension in the neck and shoulders. Pillows that conform to the shape of the head and neck help keep the spine aligned. Memory foam is well-known for its conforming nature, while latex also offers pressure relief.
• Quality Materials: The quality of materials used in a cooling pillow determines its lifespan. Many cooling pillows are made with high-quality materials that are especially durable. This includes natural latex and foams that offer shape retention and support. As a result, cooling pillows often last longer than other pillows.
• Firmness Level: For cooling pillows, a medium soft to medium firm feel is common.  Materials like wool, down, and shredded memory foam are often soft. Solid foam and latex pillows are more likely to be medium to medium firm. Buckwheat pillows and some foam options can be firm. When shopping for a pillow, personal preferences and sleeping position often determine which firmness level is the right fit.
• Loft: Loft refers to the height of the pillow. Cooling pillows often have a medium to high loft. Some materials like shredded foam, down, and wool have a high loft but compress easily. Certain cooling pillows have an adjustable loft, meaning you can remove or add filling to change the height of the pillow. A higher loft is better for side sleepers, while back sleepers tend to prefer a medium loft. Stomach sleepers benefit from a low loft.

What Materials are in a Cooling Pillow?

A cooling pillow uses materials in its fill and cover to regulate temperature and dissipate heat. We’ll break down common fill and cover materials here. It should be noted that certain materials are highly conductive and draw heat away from the body. Others allow air to flow through them to dissipate heat. There are multiple options available, and certain pillow types will work better for some than others.

Fill Materials

• Latex: Latex is made from rubber tree sap, which is harvested and processed using the Dunlop or Talalay method. Dunlop latex is heavier, with a dense bottom and resilient feel. Talalay latex requires more processing, with a homogenous and breathable result. Latex offers ample pressure relief and is more breathable than synthetic foam. Some heat retention is possible, but many cooling pillows use aerated latex to dissipate heat and encourage airflow.
• Memory Foam: Memory foam is a viscoelastic polyfoam that responds to heat and pressure to conform closely. This results in a customized feel for sleepers and pressure relief for the head, neck, and shoulders. Memory foam pillows may retain heat and restrict airflow, so look for a cooling pillow that offsets this. Open-cell memory foam has better airflow. Memory foam can also be shredded to let air circulate, or infused with gel or copper to draw heat away from the body.
• Gel or Copper: Gel and copper are highly conductive materials that pull heat away from the body. These can be added to other fill materials, most often foam. Gel has a cool to the touch feel. Copper is antimicrobial. These materials prevent heat from building up in the pillow, but they often result in a higher price point.
• Buckwheat: Buckwheat hulls are the shells of the buckwheat grain. The hulls have an open shape and create air pockets in the pillow. This prevents heat retention. The hulls are malleable and supportive. Buckwheat pillows may take some getting used to, as the hulls have a natural odor and are prone to making a rustling noise when moved.
• Wool: Wool is harvested from lambs and sheep. The natural fiber has a crimped shape that adds ample loft and airflow to a pillow. Wool acts as natural insulation, so it pulls heat and moisture away in warmer climates and retains heat in colder areas. A wool pillow is best for those who want year-round temperature regulation.
• Down Alternative: Down alternative is often made with polyester or synthetic fibers that imitate the feel of down. This offers a vegan alternative to down, which is made with the down feathers of geese or ducks. Down alternative fill is less likely to retain heat than down. It is also more affordable.

Cover Materials

• Cotton: Natural cotton fibers are soft and breathable. There are several varieties of cotton, and the fibers can vary from short-staple to extra-long staple. Pima cotton and Egyptian cotton are types of extra-long staple cotton that are soft and breathable. Cotton naturally wicks away moisture for a cooling feel. This material is often used in covers as it increases airflow and is easy to clean.
• Phase-Change Material: Phase-change materials control temperature by absorbing body heat and releasing it. These materials change from a liquid to solid state to regulate temperature. Textiles that incorporate phase-change materials are often used in cooling pillows to draw heat away from the body.
• Bamboo: Bamboo is a natural fiber that is moisture-wicking and lightweight. It is more absorbent than cotton, making it an ideal choice for hot sleepers who sweat throughout the night. Bamboo is breathable and increases airflow throughout the pillow.

What Are the Pros and Cons of a Cooling Pillow?

Many shoppers are drawn to cooling pillows for their temperature-regulating properties. These pillows reduce heat retention and are an important part of creating a comfortable sleep environment. However, due to the cooling properties and materials used, cooling pillows are more expensive. There are a few pros and cons shoppers should consider before purchasing a cooling pillow.

Who is Best Suited to a Cooling Pillow?

Hot sleepers especially benefit from cooling pillows, but there are also benefits for side and back sleepers. It is important to consider sleeping position and personal preferences when shopping for a pillow. A cooling pillow might not be right for everyone and there are special considerations that should be kept in mind.

A cooling pillow is best suited for:

• Hot Sleepers: Hot sleepers need cooling bedding to prevent overheating. This allows them to sleep comfortably, as temperature and sleep quality are connected. A cooling pillow can help draw heat away from the body and provide a cooling surface for hot sleepers. A cooling pillow will also wick away sweat.
• Side Sleepers: Side sleepers need a higher loft pillow to keep the head elevated and neck aligned. Many cooling pillows have a higher loft that is suitable for side sleepers. Adjustable cooling pillows allow for additional fill and a higher loft.
• Back Sleepers: Back sleepers need a medium loft pillow that supports the head without letting it tilt too far forward or back. Most cooling pillows have the ideal loft and firmness for back sleepers. Materials like memory foam and latex contour to the shape of the head for proper support and alignment.

These kinds of pillows are not well suited for:

• Stomach Sleepers: Stomach sleepers need a low loft pillow. This keeps the neck at a comfortable angle. Some cooling pillows are adjustable, but most have a medium to high loft that is less than ideal for stomach sleepers. Stomach sleepers often prefer a soft pillow and most cooling pillows are considered medium soft to firm.
• Sleepers with Odor Sensitivities: Cooling pillows often use synthetic foams or natural materials that prevent heat retention. Synthetic foam tends to off-gas, which causes a chemical smell in the pillow. This usually dissipates within a few days, but those who are sensitive to odors may notice it for longer. Materials like wool and buckwheat also have a natural odor that may be off-putting to sleepers with odor sensitivities.

Other Tips for Sleeping Cool

A cooling pillow is an essential part of a comfortable sleep environment, but it is just one component. Hot sleepers can take additional measures to stay cool throughout the night.

• Bedding: Using breathable, lightweight bedding prevents heat retention. Natural materials like cotton, bamboo, and eucalyptus are ideal. These fibers are commonly used in cooling bed sheets, comforters, and duvets. Pay attention to thread count and weave to ensure the bedding allows air to circulate. A percale weave offers a crisp and cool feel for hot sleepers. Avoid heavy fabrics and synthetic materials that are not breathable.
• Room Temperature: A cool room improves sleep quality. The ideal room temperature is around 65 degrees Fahrenheit. Set the thermostat in this range, and use a fan to keep air circulating. Window shades can act as insulation, preventing hot air from coming in and cool air from escaping.
• Mattress: There are plenty of mattress options that regulate temperature and prevent sleeping hot. The best mattresses for hot sleepers are often made with latex or gel-infused memory foam. A hybrid construction with coil support increases airflow throughout the mattress and can make a significant difference for hot sleepers.
• Pajamas: What you wear to bed plays a role in how well your body regulates temperature. Opt for natural, breathable fabrics like cotton and bamboo. Avoid heavier fabrics, thermal pajamas, or flannel pieces.
• Mattress Topper: If buying a new mattress is not in the cards, a mattress topper can be an affordable way to make your current mattress more comfortable. Toppers act as an additional comfort layer and can improve the temperature regulation of the mattress. Aerated or gel-infused foam, latex, and wool are all breathable mattress topper options.
