10 Best Cooling Pillows of 2021 for Side Sleepers

The best Cooling Pillows are the new cool. Why? Because they are cool! Pardon my humor; but honestly, they are really cool. I would often wake up at night all hot (no, the other one) and sweaty. My pillow would be like the inside of an oven. My pillow would be piping hot, and I would have to get up and change its side. But that wouldn’t last that long either; the other side would start grilling in no time. I didn’t care much about it in the start because who doesn’t like being hot.

But my hotness soon turned out to be a nuisance for me. Sleeping became a struggle for me. I couldn’t get enough sleep just because my pillows became super-hot and extremely uncomfortable to sleep on.

And in no time, I was on the verge of a mental breakdown, all because of losing my sleep to uncomfortable pillows.

I didn’t care much about it in the start because who doesn’t like being hot. But my hotness soon turned out to be a nuisance for me. Sleeping became a struggle for me.

I couldn’t get enough sleep just because my pillows became super-hot and extremely uncomfortable to sleep on. And in no time, I was on the verge of a mental breakdown, all because of losing my sleep to uncomfortable pillows.

Hence, I decided to consult a sleep specialist before I stopped being myself anymore, at all. My sleep specialist told me that pillows aren’t very breathable; they are all stuffed with so many fillings and insulation.

Pillows absorb the heat from your body and retain it within themselves because there is almost no way out. This continuous absorption of heat from the body makes the pillows hot and eventually near impossible for one to sleep on them.

It is scarier than it sounds because you cannot go changing pillows every day. The solution I came to know about this one looks like an internet scam with the difference that it is not an internet scam. The solution for better sleep is a ‘cooling pillow.’

Cooling pillows is the term coined around for the pillows that offer and provide temperature neutrality to the one using by allowing more aeration.

These enable the user to sleep in a better way than before because they are relatively calm and doesn’t need flipping every now and then like burgers.

The ‘cooling effect’ provided by these cooling pillows is by the use of special fabrics that allow the air to pass through the pillow and hence make it more relaxed. Furthermore, in addition to the fabrics, the use of new scientific filling materials is also on the road to mainstream usage.

These special materials include memory foam, latex, and polyester, and often all of these infused with gel. The gel here acts as a coolant by absorbing the heat from the foam and filling and allowing the person to sleep in peace.

Cooling pillows have the material that allows them to breathe and exchange the heat they have absorbed in with some cooler ones. Breathing pillows might sound unrealistic but are as real as Trump.

They release the hot captured air in exchange for the colder one. This process not only makes them cool but also provides one with a good night’s sleep.

Apart from gel-infused ones, pillows with water chambers have gained quite a popularity in the consumer market amongst the sleepers and are still on the highway to fame.

Choice of a pillow might not seem like it, but it can cause a lot of problems; especially for your spinal area. A wrong or a bad pillow can disrupt your posture and soon result in back pain.

Things get even worse for the hot sleepers because also if they go for orthopedic or medicated pillows, they cannot have the luxury of sleeping cool. It is a loss both ways.

4. Beegod Bed Pillow – The Asian Expert

We all love Chinese food, and so does Chinese stuff; mostly because it is super cheap and convenient and thoughtful. Trump might not be wrong if he claims that a significant part of our economy is taken away by others. Most of the top brands are either Asian or non-American, but why? Mostly because they are good at it.

Beegod is an Asian brand, Chinese to be specific and has made quite a good reputation in the pillow and similar industries. Beegod’s Bed Pillow is not just a simple pillow.

In addition to all of this, this bed pillow by Beegod is also capable of releasing the stored heat because of the cooling gel balls in the filling. They absorb the heat and circulates it all over, making it suitable for the hot sleepers as well. Furthermore, the down filling does not let you compromise on the softness and fluffiness of the pillow in no case.

5. Classic Brands Reversible Cool Gel – Memory Foam Double-Sided Pillow

Classic Brands Reversible Cool Gel - Memory Foam Double-Sided Pillow

Memory foam pillows might seem a bit sturdy and hard, but once they absorb your body heat, they get really soft and fluffy. Or it can also go like that memory foams can know a person’s body and adjust accordingly.

Things get even better when this memory foam is coupled with an orthopedic friendly design for the people with a backache, especially sciatica.

The medicated design allows the person to sleep without pain and wake up even fresher, without any sort of shoulder, neck, or back pain. I call this a magic pillow because it helps in all.

Now the thing that we hear the most is that foams, especially the memory foams, tend to heat so much that they become unbearable for a person to sleep on and disrupts the sleep.

Even more, the heat-absorbing tendency of the foams makes the heat emission slow. But this pillow by classic brands is the best cooling pillow of 2021 because it has a cooling gel sheet attached. Interestingly, this cooling gel is not connected just to a single side but is on both the sides, which allows the person to use any side of the pillow they like.

  • Medicated design
  • Memory foam filling


  • The cooling layer can feel a bit awkward

Guide to Buying the Best Cooling Pillow

We have all read about Goldilocks and her quest for ‘the perfect.’ The extra hot soup or the super-soft mattresses were all a no for her because they were a bit too extreme.

Similarly, the heat of the pillow can also be catered in the same category where a snow-cold pillow will be a torture, and a hot one will be nothing less than a trip to hell. Regular pillows have air locked in them, which is almost identical to a prison.

You can enter the pillow, but you will not be leaving it any time soon. Cooling pillows, however, are innovation and a solution to this heated up pillows. In cooling pillows, the materials that have been traditionally used in the conventional pillows have been replaced by the new ones.

These new materials allow the pillow to act something like a heat exchanger. The heat stored in the pillows is moved out because of the now more ‘penetrable materials.’

These porous materials are simply referred to as the breathing materials because they allow the air to come in and go out; as it happens in the usual breathing cycle.

The advent of cooling pillows is another example of technology coming to our aid at the hour of need. The modern era realized the problems of the past and decided to tackle them with innovations.

Out of all the solutions, a cooling pillow is one and one of my favorite ones for certain.

These innovative pillows are for the ones with sleeping problems and are made up of materials that we now call breathable.

Breathable can easily be explained as something that can exchange the air in and out.  The list of these materials includes polyester, latex, memory foam, feather, down, down alternative, and buckwheat.  

This is rather an impressive number of alternative fillings we have found, but things get tricky here as well. Well, let us do the honor of explaining the properties of each so that you can know what you need. But before that, let us explain in detail how these pillows work.


We have mentioned it above as a summary of how pillows get hot and why you need to get cooling pillows, but now let’s please the nerds in ourselves.

The working of each cooling pillow is different and is dependent upon the fill they have.

The fill on cooling pillow

Breathable Cooling Pillows

Just as it is said in the name… these pillows can breathe. They absorb the heat from your body, especially the one accumulating in the head like all other pillows.

But what they have different is that they don’t just keep the air trapped in themselves. In the traditional pillows, the air gets trapped between the cotton fill, and soon the cotton absorbs the heat from the air because it cannot find another way out.

Since cotton is an insulator itself, the heat is locked in it for quite a while, and you cannot just get rid of it that easily.

The breathing pillows have a breathable structural design which does not keep the air trapped and allows the hot air to move out of the pillow and be replaced by the cooler one.

This is simple elementary grade physics where heat moves from one point to another, but in this case, to the other air since the hot air is not trapped itself.

Cooling Gel-Infused Foam

Cooling gel is a chemical that matches the temperature of the room, and therefore, when you sleep on it, it tends to absorb the heat from your head and emit it to maintain its temperature. In this case, cooling gel is used in the form of a thin layer packed in a sheet.

This is because rather than allowing the air to change or rotate, cooling gel cool pillows do not depend on air at all. They use an extra layer of thin gel to keep you cool throughout the night.

Phase Change Material (PCM) Beads Infused Foam

Phase Change Material, more commonly known as PCM is something that has been delivered to us by the mighty NASA itself! PCM is not just able to simply absorb the heat from you but also to release it as well and hence make your sleep a peaceful one.

PCM is used in the form of beads that not only increases the surface area for absorption and emission by several folds but also makes it possible to rotate or fold the pillow without causing the gel or water to leak out.

Water Cooling Insert

We all know how good water is when it comes to taking one’s heat off. Scientifically speaking, water has a very high specific heat capacity. In simpler terms, we can also call it as water needs high amounts of energy to bring small changes in its temperature.

This property of water puts it out as the best candidate for a heat exchanging system. Water is also used in the cooling pillows, and that mechanism goes by the name of Water Cooling Pillow Insert.

It is about half an inch thick padded bag which contains water. But it is not just water, though. This bag is filled with a thin layer of polyester foam and water.

This not only spreads the water evenly around but also prevents the water from squishing to the other side when one puts his head on the ­pillow.

The water absorbs the heat from one’s body, and in result, a very less change in temperature is observed.

Filling Materials

The cooling, heating, and soothing properties of a pillow are in a direct relationship with the material used. The material used in a pillow has a linear effect with the ease it is heated.

The materials that are used commonly as a filling for the pillows include:

  • Buckwheat
  • Latex
  • Memory Foam
  • Feather
  • Down
  • Down Alternative


Buckwheat is one hell of a nutritious feast, but its uses are not just limited to that. Astonishingly, it is used in the pillow industry as well.

Hulls of Buckwheat are used as a pillow filling, especially for the cooling pillows, and they do one marvelous job. Buckwheat hulls are the hard shells around the kernels.

They are hard and therefore, uneven which doesn’t allow them to settle over each other. This gives them the space needed in the cooling pillows. Air can move easily across the pillow and not just get trapped or accumulated at a single point.

I know using hulls sounds ridiculously uncomfortable because of the hardness, but the results are even surprisingly different. The shells of buckwheat have this unique ability to conform to the shape and size of the one using it and are also provide excellent support for your neck and head.

Buckwheat pillows can evenly distribute your weight all around and are even believed relax the muscles by releasing the undue stress.

Buckwheat pillows are one of their kind because they might not give you that cooling sensation, but they do not drop the temperature either like the other modern, technology-based pillows.


Down is the fluffy, feathery fuzz that is found beneath a duck’s feathery coat. It is soft and fluffy, to begin with, and provides the neck and head with an extremely comfortable, relaxing, and a soothing sensation.

Down-filled pillows are heaven to sleep on; have very much in common to the Mama Bear in the Goldilocks story.

Down is capable of absorbing the heat from one’s body, but its release does take a while, which causes the pillow to have a rise in temperature. This said rise in the temperature is low for the regular sleepers but can get a bit uncomfortable for the hot sleepers.

Therefore, to make up for this change in temperature, water cooling inserts can be used in combination with the down as a pillow filling.

Down Alternative

Down alternative, as the name suggests, is an alternative for the real down. It is a synthetic material that is manufactured from the polyester puffballs and is designed in such a way that imitates the properties of the original down.

A man hand on a cooling pillow

Unlike the original one, the alternative to down has a lower temperature. This suggests that the down alternative has better cooling properties than the real down.

Where real down is known to trap the air within, the alternative to down allows a gentle circulation within the pillow to keep you cool all night long.

The even more amazing thing about this alternative for down is the price. Usage of down alternative is more pocket-friendly than the real one, thus making it a better option than the original down itself.


 We all know what feathers are. Feathers have been the standard filling in the pillows from ages and have been symbolized by the movies.

The feathers used in the pillows are of ducks and geese. And since these feathers are not responsible for insulating the birds, they have a better flow and circulation throughout.

Feather pillows have a characteristically unique feel which is second to none. Feather pillows are firmer than the down-filled pillows and even tend to stay cooler for longer periods.


Most of the people know what latex is but often confuse it with other forms of plastic or rubber. Latex is a stretchy substance derived from the fluid of rubber trees.

Application of rubber for cooling purposes almost sounds ironic, but the fun part is that if it is appropriately designed, it can provide cooling as well.

Latex cooling pillows are aerated in design structures and hence tend to stay more relaxed even though they can trap heat. Their aerated designs cause more air circulation and thus the refreshing sleep. This is one of the reasons why latex pillows are famous among the hot sleepers.


On behalf of all the nerds, scientifically speaking, polyester is a macromolecule of esters and is really soft and resembles foam itself. For a layman, a macromolecule is when a long chain of a substance is formed and hence the prefix ‘poly.’

Polyester has synthetic microfibers which absorb and trap a certain amount of heat but is not enough to raise the temperature of the pillow to uncomfortable.

 High and even good qualities of polyester have fair temperature neutrality but can get warm enough to be uncomfortable for many of the sleepers. Polyester pillows are however low cost and are, therefore, one of the most chosen ones.  

Memory Foam

Memory foam is what that seems closest to the apex of the foam making. These foams are a bit harder than the usual ones, but they get softer once they are warm or record a rise in temperature.

However, just like other foams, memory foams also can absorb and trap heat inside, and its release is a very lengthy procedure.

To make memory foams friendly and usable for the hot sleepers, the foam either has to be shred or is infused with cooling gel. This infused gel keeps the foam from becoming too hot.

The same purpose is also served by shredding because it allows the air to flow in and circulate. Hence, the temperature stays relatively lower than the regular, traditional pillows.

Frequently Asked Questions

Hot sleepers release excessive heat during their sleeping cycle, which makes their pillows hotter than others. Regular pillows have no means of exchanging the air around or to release the trapped heat and become uncomfortable. Cooling pillows have a flow of air or a cooling pad to keep you cool throughout the night.

Cooling pillows do get warm by absorbing one’s body heat, but this process is much slower than the other pillows. Depending on the fill and the type of coolant, cooling pillows can stay cool from a couple of hours to almost 5 to 6 hours.

The gels and the fillings can be highly toxic at times and should be refrained from ingestion. However, in the case of ingestion, one should immediately contact the ambulance and hospital.

I like the buckwheat pillows for my personal use, but people find them a bit irritating and discomforting. Gel-infused memory pillows are the best to be used if the budget is not an issue.

Silk is the most common material that is used for pillowcases. Silk has a cool feel and therefore preferred for the same.


Aren’t cooling pillows the best? Especially for the flashes. Even I am a hot sleeper as I have mentioned before and things have gotten pretty scary for me. Before I knew about cooling pillows, my sleep was short-lived, and I had no way of getting it back. However, cooling pillows have changed things for me.

They let me sleep at night with peace. Cooling pillows are not only advanced in providing one with a soothing, cooling effect but also provide an improved and enhanced support to your head and neck. We have sorted the best cooling pillows for the hot sleepers and have also separated the best cooling pillow of 2021, best cooling pillow with memory gel and the best comfortable cooling pillow.
