Tossing and turning in bed can be really exhausting. I am one of those people, who often struggle to put oneself to bed, as though insomnia has become my partner that won’t quit no matter how hard I try. More often than not it’s the heat that keeps me up. I heard about the cooling blankets and decided to find out if they actually worked and if there was any science behind them before I make my well-informed decision to purchase one. This guide is my humble attempt at getting to the bottom of it. Feel free to join me on this research to find the perfect cooling blanket that will make you sleep through the night.
So, what is a cooling blanket? Cooling bedding is essentially a temperature-regulating set of bedding accessories that can include cooling pillows, mattresses, sheets, and blankets. This guide will specifically concentrate on cooling blankets. There are different types of blankets that claim to regulate body temperature, and we’ll look at them in detail later on in this article.
Most of the research into benefits and limitations of cooling bedclothes concerns medical aspects and treatment of various conditions in both adults and children.
One of the most researched subjects in those studies is fever management with the use of external cooling blankets. The study that was published in Clinical Infectious Diseases (2000) concluded that while physical cooling methods are generally indicated for fever treatment, the use of cooling blankets remain controversial “because of their propensity to induce cutaneous vasoconstriction, shivering, sympathetic activation, and, perhaps most importantly, discomfort.” I can certainly relate to the discomfort associated with cooling patches and cold packs that my mom used to put on my head or various parts of the body when I was ill way back in childhood. I have my own kid now, and while I do try to remove unnecessary clothing when he has a fever, I try not to go overboard with applying ice packs and cooling patches on my son’s body.
However, babies can, in fact, benefit from cooling blankets. There was a report in the American Health Journal specifically dedicated to the treatment of newborns who suffered from the lack of oxygen during the delivery. Placing the babies on cooling blankets to prevent brain damage quickly reduces their temperature, slows down their heart rate and allows them to “hibernate” while their bodies and brains heal.
The medical cooling blankets vary in sizes and shapes according to the intended purpose and function they need to perform. Most of these medical cooling blankets come with other specialised professional equipment that requires additional knowledge and practice to operate. The use of such blankets vary extensively: blood temperature control, localized therapy (burns, after surgical treatment, injuries, etc), hypo-hyperthermia, etc.
Everyday practical use
More practical aspects of the scientific studies that directly relate to the subject of our investigation are concerned with cooling technologies that were initially developed for NASA.
Since 1950s NASA scientists have been researching materials that would protect astronauts in space from drastic and extreme changes in temperature. The earlier space suits were cooled by running water through small channels throughout the suit, but they were not very practical.
In the late 1980s NASA, in conjunction with the US Air Force, developed passive temperature control strategies that resulted in the creation of Phase Change Materials (PCMs), which would later be used in spacesuits.
In the 90s the technology became available to the general public and was incorporated in bedding, garments, and medical supplies. This technology is now known as Outlast technology: it utilizes microencapsulated PCMs that absorb, store, and release heat. When describing how the technology works, the Outlast compares it with an ice cube that changes from solid to liquid by melting in a drink and keeping it cool.
There are other technologies available for cooling blankets, but they are not as outstanding and scientifically proven as the Outlast, and we’ll cover them later while describing the types of cooling blankets.
Cooling accessories can be beneficial for those who suffer from hot flashes and night sweats. These conditions seldom indicate serious medical conditions, like fever, recent excessive weight-loss, menopause, diarrhea, localized pain, and various sleep and anxiety disorders.
Night sweats can also be a side effect of taking medications, like antidepressants, diabetes, or hormone-blocking drugs.
If you are not struggling with any of the above-mentioned diseases, night sweats should not be a cause for serious concern.
But in any case, whether you are taking medication, struggling with anxiety, or just feeling hot because well, it is summer night for god sake, cooling blanket can be your lifesaver. Or at least it can help alleviate the sweating and inconvenience associated with excessive heat.
I’ve found a great deal of blankets that can provide satisfactory cooling effects. I’ve further divided them into several groups so it would be easier for you to choose.
If you just want to find the most organic and breathable material for your bedding, and would not want to pay a fortune for any of the NASA technologies, then stick with regular high-quality cotton, linen, or bamboo fabrics.
If choosing between these three, I would suggest going completely 100% bamboo. There was a study published in the Journal of Applied Research and Technology comparing regenerated bamboo and cotton performance in warm environments that concluded that both cotton and bamboo had low thermal conductivity and were “excellent materials to fabricate summer clothing”. However, if chosen between the two, 100% regenerated bamboo significantly reduced heat storage rate in the human body without compromising comfort. One of these very simple cooling blankets is NuvoLe Cooling Throw Blanket from 100% Bamboo Fiber.
Linen is also well-known for its cooling properties, high moisture absorptivity and moisture vapor transmission rate, high air permeability and stiffness. It’s also scientifically proven to be cooler than cotton or silk. One of the good examples of 100% linen blankets is the Sofia's Linen Pure Flax Linen Blanket.
The Outlast technology has been discussed above. This technology was initially developed by NASA scientists when they were looking for materials that would help regulate extreme temperatures that astronauts face in space. The Outlast blankets have a special lining that continuously interacts with the human body and regulate its microclimate by adjusting its temperature to either release heat or absorb it. One of the basic examples of these cooling blankets is Outlast Hypoallergenic 100% Cotton Blanket.
Weighted cooling blankets
Another type of cooling blankets is so-called weighted cooling blankets. Weighted blankets are essentially comforters with pellets, beads, chains woven throughout the bedding for the weight to be evenly distributed when a person lies underneath it.
While weighted comforters have been used in mental health practice for a long time, it was not until 2017 when they become widely known and popular across numerous demographics thanks to the Kickstarter campaign for the Gravity Blanket.
The basic notion behind weighted blankets is that they help cope with stress and anxiety and various other mental health issues by providing constant tactile stimulations across the body.
You can essentially choose any weight you want from 5 to 25 lbs.
The study published in Journal of Sleep Medicine & Disorders confirmed that the gravity blankets indeed had a positive impact on sleep, stating that “when the participants used the weighted blanket, they had a calmer night’s sleep, with a decrease in movements.”
While there’s no way you can substitute regular therapy and medication for a simple blanket, people with autism and other developmental disorders can indeed benefit from gravity blankets, which can calm, relax, distract, and increase reality orientation.
The cooling effects of these blankets, however, come from the earlier discussed fabrics: bamboo, linen, and cotton. The manufacturers often claim that they use a mixture of certain cooling fabrics that wick moisture away from the body. Some of those materials can be 87% polyester and 13% spandex.
Air Conditioning (AC) cooling blankets
Another type of cooling bedding comes with a special cooling electric device that looks and acts like a mini air conditioner. One of the examples of such electric cooling blankets is BedJet AirComforter Dual Zone. The cooling comforter is an accessory to the BedJet Climate Control System and is plugged into the BetJet air supply in order to function. Similar devices work the same way. To say the truth the whole AC idea looks a bit clumsy and will definitely incorporate extra space. Some of the similar to BedJet devices can look as ridiculous as this one:
Cooling blankets for pets
A somewhat entirely different subset of cooling blankets is intended for animals. Dogs specifically can benefit from the cooling bedding: they cannot cool themselves by sweating like humans, they would sweat a little bit through their pads, but their primary cooling mechanism is panting. Unfortunately, if it’s too hot, panting won’t be enough and the dog will suffer from the excessive heat.
There are several types of cooling beds but the main ones are:
- Water-filled cooling beds - these are essentially pads that you fill with cold water. They are not very practical: they can spill, leak, or tear down.
- Pressure-activated cooling pads for dogs - these are gel-based; the chemicals in the pads absorb the dog’s excessive temperature thus, cooling her down. One of the good representatives of pressure-activated cooling pads is The Green Pet Shop Dog Cooling Pad that’s easily recharged, designed for large dogs and would keep them cool for 4 hours straight.
Unfortunately, there’s nothing specifically created for cats. So if you think your cat suffers from the heat, you might buy one of the pads that are designed for dogs, or opt for simple breathable fabrics. Look at this cooling blanket for cats and dogs, for example, PAWZ Road Pet Blanket. It’s made of breathable mesh and self-cooling fabric that will keep your pet cool and comfortable.
In case you wonder, there are cooling blankets for horses too. These are made of cooling fabrics like polyester fleece with antistatic technology and hydrophilic quality that regulates body temperature of an animal. Weatherbeeta Anti-Static Fleece Cooler is one of these cooling blankets for horses.
Things you would probably want to consider are:
- The space that you have available in your bedroom. If space is your concern, then BedJet and likewise products won’t probably be the best solution
- Do you suffer from any medical condition? If you have any mental issues, then weighted cooling blanket might be the answer
- Would you like to try the new technology that’s supposedly approved by NASA? Then Outlast is your bet!
- Budget. Last would be price, and this would be first if you have a tight budget. Opt for simple breathable fabrics if budget is your primary concern.
- Primary user: child, pet, spouse, or yourself.
Now, let’s cover the TOP 6 best cooling blankets for humans that are currently available on the market. We’ll cover everything from fabrics to the sophisticated high-end cooling control systems.
Outlast Woven Temperature Regulating Blanket - 100% cotton
Outlast (as was discussed earlier in this article) is a special cooling technology that was initially developed by NASA scientists and then later became available to the general public.
This cooling blanket is made of 100%cotton sateen weave. Outlast technology micro-capsules called Thermocules absorb, store, and release heat to help you maintain optimal sleep temperature.
Available in four sizes and colors to match your space needs and room aesthetic.

The Original Gravity Blanket - 100% cotton
This is the original Gravity blanket that was developed as a result of the Kickstarter project to help spread mental health awareness and benefits of weighted blankets across various demographics.
The gravity blanket uses “deep touch pressure stimulation” to help improve quality sleep and relaxation. The super soft microfiber material keeps you cool, comfortable, and calm.
This cooling blanket dimensions are 48 inches by 72 inches, which is suitable for one person. You can choose between 15 lbs and 25 lbs, with 15 lbs suitable for a person weighing no more than 150 pounds.
Unfortunately, the buyers commented on the problems that Gravity had with manufacturing which resulted in the unevenly spread weighted beads that shift wherever you move the blanket to. Perhaps, one of the batches was not up to the standards. Fortunately, there are other options available for you to choose from.

Quility Premium Adult Weighted Blanket & Removable Cover - 100% cotton
This is yet another cooling weighted blanket that can help you deal with both mental issues and night sweats.
Ultra soft 100% cotton material is filled with non-toxic hypoallergenic glass beads. The beads are placed in special pockets to prevent them from unevenly spreading out across the blanket.
The Quilty features a soft removable cover, which makes washing and taking care of it easier and less of a hassle.
The manufacturer promises, that deep touch therapy and cooling feel of cotton material will make your sleep finally comfortable and serene.
Quilty provides recommendations for choosing the right size and weight for any person: choose 15 lbs if your weight in under 180 lbs, choose 20 lbs if it falls between 170 and 230 lbs. If you have a twin bed, then 41 by 60 inches will do the job, for the queen bed - 60 by 80 inches.

YnM Cooling Weighted Blanket - 100% Natural Bamboo
This cooling blanket from YnM is made of a silky smooth 300 thread count bamboo viscose filled with polyfill and glass beads. Comes with two extra layers of durable and breathable cotton fabric between the bamboo layer and the thin polyfill to maximize the durability and ensure beads stay in place.
Available in the array of sizes and colors: 14 sizes and 10 colors.
Consumer response to this one is overwhelmingly positive.
BedJet V2 Climate Control for Beds, Cooling Fan + Heating Air - the entire cooling control system
This is a totally different product that is comprised of two BedJet base units, two wireless remotes, one King AirComforter sheet and free Bluetooth App for control from your iPhone, iPad, or Android device. This system is seldom called electric cooling blanket.
The BedJet has a dual zone control temperature with two modes. Powered ventilation cooling that wicks body heat and moisture out of bed providing relief from night sweats and hot flashes. And a heating mode that heats the bedding 15 times faster than a regular electric blanket providing a solution for cold feet and legs.
The BedJet system has to be put underneath the bed with 7 inches space with side rail clearance being 3.5 inches.
On the downside, the product obviously needs space and can look somewhat clumsy and bulky. And of course, it’s pricey.
