Do you have trouble sleeping through the night because the bed gets too hot? You’re not alone. In fact, there are enough people who struggle with hot sheets that manufacturers have come up with several solutions. Via a variety of materials as well as technology designed specifically for the task, they have created cooling sheets that keep a consistent temperature throughout the night, allowing you to finally get some truly restful sleep.
To start, let’s go over the basics for the features that create a cool, temperature regulated, sleeping experience in a sheet set:
- Breathability: if you want to sleep cool, you need a breathable fabric (by far the most important feature of a cooling material) – the tradeoff is often that more breathable fabrics are coarser and thus sometimes don’t feel as soft as less breathable fabrics. This is why linen, for example, feels more rough than silk, but it is much more breathable (hence why we wear it summer)
- Thermal effusivity, conductivity, and specific heat
- Thermal effusivity is a measure of how ‘cool’ a material feels. For example, if it is cold outside during winter, and you touch a metal pole, you’ll notice that it feels cooler than wood – this is because it has a higher thermal effusivity
- Thermal conductivity is a measure of how well a material conducts, or pulls heat, away from your body – thus a material with a higher thermal conductivity will lead to a cooler sleeping experience
- Specific heat is a measure of how much ‘heat’ a fabric can store – for hot sleepers, you generally want a fabric that has a higher specific heat, so it can store more heat from your body.
- Moisture management: simply put, moisture-wicking is the process of moving moisture away from your skin (think Lululemon/dry fit clothing). Thus, moisture wicking fabric has two jobs: (1) move moisture from one place to another and (2) dry rapidly so that the sweat doesn’t saturate the fabric. Moisture wicking fabric is generally cooler than moisture absorbing fabric (all things held the same) because it helps water evaporate off our bodies. When we want to stay dry, we often wear moisture wicking clothing (like Lululemon or other athletic wear) instead of fabrics like cotton, which tend to retain a lost of moisture
With these factors in mind, let’s discuss the various materials, their pros and cons, and how they impact your sleep experience.
There are a number of materials that claim to have cooling and temperature regulating properties – linen, bamboo, polyester blends, and cotton – the most important thing to keep in mind is that you are looking for a sheet set that promotes airflow, wicks away moisture, and pulls away body heat. Moisture-wicking fabrics and weaves can help to keep us from overheating as we sleep. In our experience, and according to research across the Internet, linen and bamboo are the coolest fabrics to sleep on because they are the most breathable and have the best moisture management, effect, but the other fabrics have their benefits as well. Ultimately, it’s all about what you prefer. The material is excellent for summer clothing, and that extends to sheets as well.
Here is our rank for the coolest fabrics to sleep on:
- Linen – linen is always going to be the coolest fabric – it’s the most breathable (hence why so many people wear it in the summer!). It also absorbs a lot of moisture and cools quickly, keeping you cool and dry. Some people don’t like the slightly coarser feel of linen.
- Bamboo – bamboo is the best moisture wicking fabric. It’s also breathable (though not quite as breathable as linen). It’s also incredibly soft, which is why it is such a popular fabric for sheets and even clothes.
- Cotton – cotton is a classic material that is going to be soft, breathable, and generally cool. The issue with cotton is that it’s so hit or miss depending on the quality of the cotton you get.
- Polyester blends (the blend part is important) – polyester blends, particularly those with spandex and/or nylon are cool – but be careful, there is a lot variability with polyester fabrics, so make sure you find a good one. We’ve found that people either love these fabrics or they hate them – rarely an in between. So if you’re going to get these, look for a brand that has a generous return policy.
Lastly, it’s important to also evaluate the weave and thread count of the sheets you choose – thread counts that are too high (over 400) are going to be warmer because they are less breathable. (Not to mention that high thread counts are usually deceptive, anyways). Finally, it’s important to note that a percale weave is cooler than a sateen weave (because it is more breathable).
There is an entire science-based around temperature regulation in the bedding industry. The best temperature for sleeping is around 65 degrees, and the aim is to keep sheets at a consistent temperature close to that ideal throughout the entire night. While there are many options to consider, we’ve found that linen-bamboo sheet blends were the most breathable, moisture wicking, and temperature regulating sheets on the market. Not to mention, we love the luxe, incredibly soft feel.
#1 Best overall cooling sheets: Dosaze ThermaCool Linen-Bamboo Temperature Regulating Sheets – CHECK PRICE
The Dosaze ThermaCool Linen-Bamboo Temperature Regulating sheets are the cream of the crop, the crème de la crème. They are by far the coolest sheets that we tested (not to mention the softest and most comfortable).
Dosaze combined the breathability of linen with the moisture-wicking and soft feel of bamboo to produce the best sheet set that we tested.
After testing this fabric, we found that it has a higher thermal effusivity (cool to the touch sensation), thermal conductivity (ability of material to pull heat away from your body), and specific heat (ability of the material to store heat) than cotton. The science backs up our personal experience sleeping in these sheets.
Furthermore, we it is also true that linen-bamboo is more moisture wicking than cotton and more breathable – it really facilitates a cooling sleep experience and is so luxuriously soft.
If you toss and turn all night because your pillow is always getting hot on one side, then there’s some bonus good news for you: the set comes with pillowcases with the same temperature regulating technology.
