Have you ever woken up in the middle of the night feeling hot and sweaty? If you're a hot sleeper or someone who deals with night sweats, you know how tough it can be to get a good night's rest. This is where cooling comforters come to the rescue! These special blankets are made to keep you cool and dry throughout the night. But how do they actually work? Let's dive into the cool science behind these sleep-saving beddings!
One of the most exciting cooling technologies today is the Promeed Ice Velvet™ filling. This special material feels cool to the touch and helps draw heat away from your body while you sleep.
The secret of Ice Velvet™ is in its fiber structure. Unlike regular comforter fillings that trap heat, Ice Velvet™ has tiny channels that let air move freely. When you lie under a comforter with this filling, your body heat doesn't get stuck. Instead, it flows through these channels and away from you.
These special fibers also have something called "high thermal conductivity." In simple words, they can quickly move heat from hot areas (like your body) to cooler areas. This is why when you first touch an Ice Velvet™ comforter, it actually feels cool!
Many hot sleepers say that switching to a comforter with Ice Velvet™ filling has helped them sleep better. They don't wake up as often feeling too hot, which means they get more restful sleep throughout the night.
Did you know that when you sleep, your body can release up to a cup of sweat each night? That's a lot of moisture! This is why good cooling comforters don't just deal with heat—they handle moisture too.
When moisture (sweat) sits on your skin, it makes you feel clammy and uncomfortable. Cooling bedding works by wicking away moisture from your body. Wicking means drawing moisture away from one place to another.
Here's how it works:
The best cooling comforters use materials that are good at both wicking moisture and helping it evaporate quickly. This two-step process is key to keeping you cool and dry throughout the night.
Some cooling comforters even have layers specifically designed for moisture management. The layer closest to your body pulls moisture away, while outer layers help that moisture evaporate into the air.
Not all fabrics are created equal when it comes to keeping you cool. Tencel™ is a special fabric that's become very popular in cooling bedding because it's amazingly good at managing temperature.
Tencel™ is made from wood pulp (usually eucalyptus trees) that's processed in an eco-friendly way. The result is a super soft fabric that's better at cooling than cotton or polyester. But what makes it so good at keeping you cool?
Tencel™ has a unique fiber structure that does several things:
When you sleep under a comforter with Tencel™, it continuously works to manage both heat and moisture. If you start to get warm, the fabric quickly pulls moisture away from your body and spreads it across a larger area so it can evaporate.
Many hot sleepers find that bedding with Tencel™ feels cool to the touch even on warm nights. And because it's made from natural materials, it's also good for people with sensitive skin or allergies.
When shopping for cooling comforters, you might see the terms "active cooling" and "passive cooling." These are two different ways that comforters keep you cool, and knowing the difference can help you pick the right one.
Passive cooling works without using any power or special technology. It relies on the natural properties of materials to keep heat and moisture moving away from your body. Examples include:
Most cooling comforters use passive cooling. They work by being more breathable and less likely to trap heat than regular comforters.
Active cooling, on the other hand, uses special technology or materials that actively respond to your body temperature. These might include:
Active cooling comforters usually feel cool to the touch right away. When you get into bed, they immediately start working to lower your body temperature.
Both types of cooling have their benefits. Passive cooling tends to work well all night long and doesn't wear out. Active cooling might feel cooler at first but can sometimes lose its cooling power over time.
Outlast® technology is one of the most advanced cooling technologies used in bedding today. It was originally developed for NASA astronauts to help them stay comfortable in the extreme temperature changes of space!
The magic behind Outlast® is something called phase change materials (PCMs). These special materials can change from solid to liquid and back again as they absorb and release heat. Here's how it works in your bedding:
Think of it like tiny ice cubes woven into your comforter. As you get hot, they "melt" (without actually getting wet) and absorb your body heat. When you cool down, they "freeze" again and release that heat if needed.
What makes Outlast® technology special is that it actively responds to your body temperature. It doesn't just cool you down—it helps maintain a comfortable temperature all night long. If you get too cool, it releases some heat back to you.
Comforters with Outlast® technology are great for people who experience temperature changes during the night. They help regulate your body temperature whether you're running hot or cold.
One of the newest and most exciting materials in cooling bedding is graphene. This super-thin material (just one atom thick!) is changing how cooling comforters work.
Graphene is a form of carbon that's arranged in a special honeycomb pattern. It's one of the best heat conductors we know of—much better than metals like copper or silver. When used in cooling comforters, graphene creates some amazing benefits:
Comforters with graphene infusion often have the material added to the fibers or as a layer within the comforter. When your body produces heat during sleep, the graphene quickly picks up that heat and moves it away from you.
Many sleepers report that graphene-infused cooling comforters feel "instantly cool" when they touch them. Plus, the cooling effect tends to last longer through the night compared to some other cooling technologies.
As a bonus, graphene has antibacterial properties, which can help keep your bedding fresher for longer. This makes graphene-infused comforters a great choice for hot sleepers who want cutting-edge cooling technology.

Have you ever wondered how something so thin can keep you so cool? That's the magic of nanofibers in cooling comforters! Nanofibers are incredibly tiny threads—so small that you can't see them with just your eyes.
In cooling bedding, nanofiber layers work like a high-tech shield between you and heat. These super-thin fibers are arranged in special patterns that do several important jobs:
One of the coolest things about nanofiber technology is how lightweight it is. A nanofiber cooling layer adds almost no weight to a comforter but makes a huge difference in how cool it feels. This means you can have the cozy feel of a comforter without the warmth.
Manufacturers often add nanofiber layers to the part of the comforter that touches your body. This creates an instant cooling sensation when you slide under the covers. Throughout the night, these tiny fibers continuously work to move heat and moisture away from your sleep environment.
Some of the newest cooling comforters combine nanofibers with other cooling technologies for even better results. For example, nanofibers infused with cooling minerals or combined with moisture-wicking fabrics can keep you cool and dry even better than either technology alone.
When shopping for bedding, you'll often see the words "breathable" and "cooling." Though they might sound similar, they actually work in different ways to help you sleep better.
Breathable fabrics allow air to flow through them easily. Think of them like tiny windows in your comforter that let fresh air in and hot air out. Cotton and bamboo are naturally breathable materials. When a fabric is breathable:
Breathable fabrics are good for most sleepers and help prevent overheating. However, they don't actively cool you down—they just don't trap heat.
Cooling fabrics, on the other hand, do more than just let air through. They actively work to reduce your temperature through special properties or technologies. Cooling fabrics might:
Materials like Tencel™, cooling nylon, or fabrics treated with cooling technologies fall into this category. They don't just allow heat to escape—they actively help remove it from your body.
Many of the best cooling comforters use a combination of breathable and cooling materials. The breathable elements help with air flow, while the cooling elements actively work to lower your temperature. This combination creates the perfect sleep environment for hot sleepers or anyone who wants to stay cool throughout the night.
Not all cooling comforters work the same way or at the same speed. Some feel cool the moment you touch them, while others work more slowly over time. This difference is what separates "instant cool" from "gradual cool" bedding.
Instant cool comforters give you an immediate cooling sensation when you touch them. They typically:
The Promeed CoolRest™ Cooling Comforter is a great example of instant cooling technology. The moment you slide under it, you can feel the cooling effect against your skin.
Gradual cool comforters work differently. Instead of feeling cool immediately, they:
Both types have their benefits. Instant cool comforters are great if you struggle to fall asleep because you're too hot. That immediate cooling sensation can help you relax and drift off to sleep more quickly.
Gradual cool comforters might be better if you want consistent temperature control throughout the entire night. They work more slowly but often provide more consistent cooling as the hours pass.
Many hot sleepers find that the best solution is a comforter that combines both approaches—something that feels cool when you first get into bed but also continues to regulate your temperature all night long.
Phase-change materials (PCMs) are like tiny temperature managers hidden in your comforter. They use some pretty cool science to keep you comfortable all night long!
The "phase change" in PCMs refers to how these materials can change from solid to liquid and back again. This change happens at specific temperatures—usually around the ideal sleeping temperature for humans. Here's how they work:
Think of PCMs like tiny ice cubes that melt when you get hot (absorbing heat) and freeze when you get cold (releasing heat). The amazing thing is they can do this over and over all night long!
In cooling comforters, PCMs are often enclosed in tiny capsules and mixed into the filling or fabric. You can't see or feel these capsules, but they're working hard to manage your body temperature while you sleep.
The most advanced cooling comforters, like those using Outlast® technology, can contain millions of these microscopic PCM capsules. Each one responds individually to temperature changes, creating a smart system that adjusts to different parts of your body, similar to how a cooling blanket functions.
PCMs are especially helpful for:
Unlike some cooling technologies that work only when you first get into bed, PCMs work continuously throughout the night, helping you maintain comfortable sleep from bedtime until morning.
When looking for a cooling comforter, you'll find two main types: those made with natural cooling materials and those made with engineered cooling technologies. Both can help you sleep cooler, but they work in different ways.
Natural cooling comforters use materials found in nature that have cooling properties:
These natural materials have been used for centuries to stay cool in hot weather. They work with your body's natural cooling system by allowing heat to escape and moisture to evaporate.
Engineered cooling comforters use modern technology and specially designed materials:
These engineered solutions often provide more powerful or immediate cooling effects than natural materials alone.
So which is better? It really depends on what you need:
Natural cooling comforters tend to be more eco-friendly and can be good for people with sensitive skin. They often provide gentle, consistent cooling all night.
Engineered cooling comforters usually offer more dramatic cooling effects and might be better for serious hot sleepers or people with night sweats.
Many of the best cooling comforters today, like the Promeed CoolRest™, actually combine both approaches—using natural materials enhanced with cooling technology for the best possible sleep experience.

Did you know there are tiny minerals in some cooling comforters that help keep you cool all night? It sounds like magic, but it's actually science!
Mineral cooling uses small particles of special minerals mixed into fabrics or fibers. These minerals have unique properties that help move heat away from your body. Here's how they work:
Common cooling minerals used in bedding include:
In a cooling comforter, these mineral particles might be:
When your body heats up during sleep, these minerals go to work drawing that heat away. The effect is a consistently cool sleep surface that doesn't warm up as much as regular bedding.
Many hot sleepers find that mineral-infused cooling bedding works better than simple breathable fabrics. That's because the minerals actively work to move heat rather than just allowing air flow.
The newest mineral cooling technologies can even combine different types of minerals for better results. Some bedding might use one mineral for quick cooling and another for long-lasting temperature regulation throughout the night.
Ceramic cooling technology is one of the newer innovations in cooling bedding. Small ceramic particles are added to fabrics to create a cooling effect. But like any technology, it has both benefits and drawbacks.
Pros of ceramic cooling:
Cons of ceramic cooling:
Ceramic cooling works through a process called "far infrared reflection." Your body gives off infrared heat while you sleep. Ceramic particles in the fabric catch this heat and bounce it back away from your body instead of letting it build up in your bedding.
Some ceramic cooling technologies also change how the fabric feels to the touch. Many people describe ceramic-cooled fabrics as feeling "cool and dry" even on hot nights.
If you're considering a comforter with ceramic cooling technology, look for one where the ceramic particles are permanently bonded to the fibers. This ensures the cooling effect won't diminish after washing.
For hot sleepers, the extra cost of ceramic cooling might be worth it for the consistent cooling power throughout the night. Many users report that ceramic-cooled bedding performs better in high humidity environments too.
When we talk about cooling comforters, how well they move heat is super important. This is where conductivity comes in—some materials are good at moving heat (conductive) while others resist heat movement (non-conductive). Both types can help you sleep cooler, but they work very differently!
Conductive cooling materials:
When you sleep under a comforter with conductive cooling materials, they act like heat highways, quickly moving heat away from your body. This creates that instant "ahhh" feeling when you first get into bed.
Non-conductive cooling materials:
Non-conductive cooling works more like opening windows in a hot room—it gives heat a way to escape rather than actively pulling it away.
The best cooling comforters often use a smart combination of both:
This combination approach is what makes premium cooling comforters like the Promeed CoolRest™ so effective. They use conductive cooling for immediate relief and non-conductive cooling for lasting comfort throughout the night.
The world of cooling bedding keeps getting cooler! In 2025, we're seeing amazing new technologies that make sleeping hot a thing of the past. Let's look at some of the newest innovations hitting the market this year.
Cooling Shell Technology One of the biggest breakthroughs is the development of "cooling shell" fabrics. These special fabrics have a multi-layer design that works like a thermos in reverse:
The Promeed CoolRest™ Cooling Comforter features this new cooling shell technology combined with their famous Ice Velvet™ filling. Together, these create one of the most advanced cooling sleep systems available today.
Ice Velvet™ Advancements The Ice Velvet™ filling from Promeed has gotten even better in 2025. The newest version includes:
Users report that the new Ice Velvet™ feels noticeably cooler than previous versions and maintains its cooling power even after many washes.
Smart Cooling Textiles Some cutting-edge cooling comforters now include fibers that can actually sense temperature changes and adjust their cooling power. These "smart textiles" can:
While still fairly new, these responsive textiles represent the future of cooling bedding technology.
Eco-Friendly Cooling Another big trend in 2025 is more sustainable cooling technologies. New plant-based cooling fibers and natural mineral treatments offer effective cooling without synthetic chemicals or high environmental impact.
These innovations show that cooling bedding is becoming more advanced, more effective, and more tailored to different types of sleepers. For hot sleepers, there's never been a better time to invest in cooling technology for better sleep!
Silk has been prized for thousands of years as a luxury fabric, but did you know it's also naturally cooling? This ancient material has some impressive science behind its cooling properties.
What makes silk such a good cooling material for bedding?
The secret to silk's cooling power lies in its protein structure. Silk fibers are made of a protein called fibroin, which has a very smooth and regular arrangement. This allows heat to move away from your body instead of building up underneath your comforter.
Unlike synthetic fabrics that can feel hot and sticky, silk feels cool and dry against your skin. This is especially helpful during warmer months or for people who tend to sleep hot.
Another benefit of silk for cooling bedding is its weight. Silk provides excellent insulation despite being incredibly lightweight. This means a silk comforter can give you the cozy feeling of being covered without the heat of heavier materials.
Many luxury cooling comforters use silk as part of their design. You might find:
While silk cooling comforters tend to be more expensive than synthetic options, many hot sleepers find the investment worthwhile for silk's natural, chemical-free cooling properties and luxurious feel.
As cooling bedding becomes more popular, the market has become flooded with cheap knock-offs claiming to offer the same benefits as premium cooling comforters. Unfortunately, these budget options often fall short in important ways.
Common problems with cheap cooling knock-offs:
How can you spot these problems? Watch out for these warning signs:
The difference between quality cooling comforters and knock-offs becomes obvious after a few nights of sleep. While premium options like the Promeed CoolRest™ maintain their cooling properties wash after wash, cheaper versions often lose their effectiveness within weeks.
For hot sleepers, investing in proven cooling technology is usually worth the higher upfront cost. Quality cooling comforters will provide better sleep for years, while knock-offs might need replacing every few months as they lose their cooling properties.
With so many cooling comforters on the market, how can you tell which ones actually work and which are just making empty promises? Here are some tips to help you spot real cooling technology:
Look for specific technology names Real cooling comforters will name the specific technologies they use, like:
If a comforter just says "cooling technology" without naming what it is, be suspicious.
Check for testing data Quality cooling bedding companies test their products and share the results. Look for:
For example, the Promeed CoolRest™ Cooling Comforter advertises a Qmax value of 0.45, which indicates excellent cooling performance based on scientific testing.
Read the fine print Some companies make their cooling claims with asterisks. They might say:
These suggest the cooling effect might be minimal or short-lived.
Look for detailed explanations Companies with real cooling technology can explain exactly how it works. Their descriptions should include specific details about:
By doing a little research and knowing what to look for, you can avoid marketing hype and find cooling comforters that will actually help you sleep cooler and more comfortably throughout the night.
As more people look for ways to sleep cooler without harming the planet, eco-friendly cooling technologies are becoming more popular. These green technologies help you stay cool while also being kinder to the environment.
Plant-based cooling fibers are leading the way in sustainable cooling bedding:
These natural materials provide cooling through their breathable structure and moisture-wicking properties without relying on synthetic chemicals.
Sustainable cooling treatments are another big trend. Instead of chemical coolants, companies are using:
These treatments achieve similar cooling effects to their synthetic counterparts but with a much lower environmental footprint.
Recycled cooling materials are also becoming more common:
The best eco-friendly cooling comforters combine these sustainable approaches with effective cooling performance. Brands are finding that they don't have to choose between helping you sleep cool and helping the planet—they can do both!
Look for certifications like OEKO-TEX®, Global Organic Textile Standard (GOTS), or MADE SAFE when shopping for eco-friendly cooling bedding. These labels help confirm that the products are truly sustainable and free from harmful substances.
When shopping for a cooling comforter, you might see something called a "Qmax value." This number is super important for understanding how cool a fabric really is—but what exactly does it mean?
Qmax is a scientific measurement that tells you how quickly a fabric pulls heat away from your skin. The higher the Qmax value, the cooler the fabric will feel when you touch it.
How is Qmax tested? Scientists use a special machine called a thermal conductivity analyzer. Here's how the test works:
The Promeed CoolRest™ Cooling Comforter has a Qmax value of 0.45, which is considered excellent for cooling bedding. For comparison, regular cotton might have a Qmax value around 0.10-0.15, so the CoolRest™ moves heat away about three times faster!
What makes a good Qmax value? For cooling bedding:
When comparing cooling comforters, Qmax isn't the only thing to consider, but it's a reliable scientific way to compare the immediate cooling sensation of different fabrics.
Remember that Qmax measures the initial cool-to-touch feeling. For all-night cooling, you'll also want to look at breathability, moisture management, and other cooling technologies used in the comforter.
The best cooling comforters combine a high Qmax value with other cooling features to keep you comfortable all night long, not just when you first get into bed.
