July unofficially marks the beginning of sweaty season. After we get over the highly anticipated, jovial first month of summer, we are left traveling through high temps and higher humidity and waking up in pools of our own sweat. Yes, this one’s for the hot sleepers among us: a list of the best products for cooler sleep.

It seems no matter how high you crank up your AC, you’re still plagued by uncomfortable nights of sleep to go along with those higher electricity bills. It’s already miserable sleeping solo, but add another person to the mix and you’ve got double the body heat, and not in a hot-and-heavy way. What you need to do is invest in some cool sleeping products.

To aid you in building the ultimate cool sleeping bed, I — InsideHook’s resident sweaty sleeper — have tested a bunch of products that have not only kept me cool all night but have also provided me with a more supportive and comfortable sleep. The list below includes every sleep product you could imagine (mattresses, pillows, sheets, etc.), all engineered with cooling properties designed specifically to release heat and help with airflow while you sleep this summer.

Let’s start with the base: your mattress. I’ve been sleeping on Casper’s Snow Cooling Hybrid Mattress for about six years now, and I still sleep as well now as I did in the first weeks I got it. Unlike other foam mattresses that retain heat, Casper’s mattresses include an advanced cooling system that helps you maintain a comfortably cool temperature all night. But this specific mattress from the brand does it the best. That’s because it’s packed with layers of cold-sleep technology, which allows hot air and body heat to escape faster over a longer period of time (12+ hours).

Believe it or not, this unassuming comforter is equipped with not one, but two layers of temperature-regulating technology that has NASA’s stamp of approval. It may be the best thing I’ve slept with in a while. (It’s even received compliments from guests.) The SlumberCloud UltraCool Comforter features a combination of cooling nylon, a touch of spandex and the brand’s patented hypoallergenic fiberfill. This ingenious mixture is what gives the comforter its silky smooth feel and effective cooling properties. But it’s just as heavy as a traditional duvet, so you can cozy up under it year-round.

If you’re anything like me and haven’t given a single shit about the quality of your pillows and, consequently, have woken every morning for many years with searing neck pain, it’s time to improve your game. After literally one night’s rest with Coop Home Goods’ Eden Pillow, I felt a substantial difference (and was shocked to discover neck pain is not simply an unavoidable fact of life). The pillow’s case is crafted from sustainable bamboo — a naturally breathable fiber — for additional airflow and comfort while you sleep. But what really makes Coop stand out from the other pillows I’ve laid my delicate little head on is they come with extra filling, so you can add or take out as much as you want to achieve your desired support. It’s a choose-your-own-adventure of sorts.

If you’re looking to cool your sleep space without sacrificing your bedroom’s aesthetic, I recommend this luxe duvet cover from Parachute. Crafted in Portugal from high-end European flax, the brand’s Linen Duvet Cover is soft, protective and pleasantly light.

The easiest way to sleep cooler? Thermoregulating bedsheets. Brooklinen’s cool-touch fabric is made with premium cotton and cooling Tencel Lyocell fibers, so can you get a sweatless night’s sleep without sacrificing comfort.

You anxious sleepers have not been forgotten. Weighted blankets, if you’re unaware, alleviate anxiety and stress, help with insomnia and ADHD, and overall improve your quality of sleep. Of course, the extra weight makes it harder to release body heat, but with this cooling version from premier weighted blanket brand Bearaby, you, my anxiety-ridden friend, can have it all.

The Tree Napper is available in 10-, 15-, 20- and 35-pound weight options, eight shades and features all the same weighted technological properties as the brand’s best-selling Cotton Weighted Blanket. It’s hand-knit with Tencel eucalyptus fibers to ensure you stay cool (and calm) all night long.
