Feeling cozy might help you fall asleep, but too much heat is a sure ticket to restless, poor-quality slumber. Fortunately, there are some products that can help you stay cool and sleep deep.
According to experts, the best temperature for optimal sleep is between 60 and 67 degrees Fahrenheit. A cool environment will help you sleep more soundly and more comfortably. If you don’t have an air conditioner, though, it makes this much more difficult.
However, investing in some cooling sleep products might help you sleep better and cut down or eliminate those middle-of-the-night sweats. The materials your blankets, sheets, and even your mattress are made of can have a big impact on your body temperature.
The items below are designed to make you a whole lot more comfortable at night.
Best Mattress Topper: ViscoSoft 4-Inch Pillow Top Memory Foam
A mattress topper is a great way to make your bed more comfortable overall, but this one by ViscoSoft is especially great because it also keeps you cooler. The memory foam is breathable, so it keeps your body from getting overheated too easily. There’s also a pillow top cover for an extra layer between the memory foam and your body to really cool things down.
The memory foam also conforms to your body for a personalized feel and eliminates motion transfer, so you won’t feel every move your partner. Plus, the handy straps on each corner hold it in place.

Best Alternative Down Comforter: Linenspa All-Season
If you find yourself sweaty most nights, you should probably think about changing your comforter to something cooler. The Linenspa All-Season Alternative Down Comforter is a great option at a terrific price point.
Made with soft, all-season microfiber, it’s hypoallergenic, making it a great alternative to down. It’s also lightweight and never feels too heavy or suffocating, yet, it’s somehow still cozy. The box stitch design keeps the fill in place so it won’t clump up and will always look and feel fluffy.
The non-white versions of the comforter are also reversible, so you can switch up the look of your bed whenever you want.

This down alternative comforter is lightweight and comfy.
Best Down Comforter: Snowe Lightweight

If you prefer a genuine down comforter, the Snowe Lightweight is worth the extra money. We know from personal experience this is an instant game changer for sweaty sleepers! Made of premium French white down that’s ethically sourced, it strikes the perfect balance between lightweight and cozy.
The lightweight is best for those on the warmer side (the all-season version has 40 percent more fill and is better for people who get cold at night). The comforter has loops at all four corners to easily keep your duvet cover in place, and the fill never clumps.
Best Sheets: Brooklinen Linen Core Set

When it comes to cooling sheets, you can’t do much better than linen. It’s much more breathable than cotton and most other materials, and it’s also naturally lightweight but very soft. The Brooklinen Linen Core Sheet Set is perfect for warm weather or naturally warm sleepers because they’re 100-percent linen made from Belgian and French flax (in other words, high quality).
They come in a variety of colors, and the texture is aesthetically pleasing. They’re super-soft, and a great option if you prefer sleeping without a comforter and want as little as possible touching your skin.
Best Fan: Dyson Pure Hot + Cool
If you’re trying to stay cool while you sleep, one of the best things you can add to your bedroom is a fan. It will circulate the air and create a pleasantly cool breeze. The Dyson Pure Hot and Cool Link is certainly a more expensive option, but it also has a lot of features and is much more than just a fan.
It acts as a fan, heater, and air purifier. It cools efficiently and quietly and puts out an even breeze. You can also control it with a remote, making it super-easy to use. Plus, it has an automatic shutoff if it tips over.
As a purifier, the HEPA filter captures 97-99 percent of allergens, so it’s helpful for anyone who has allergies, or if you have pets, dust, pollen, or mold spores in your home. It’s not a substitute for an actual air conditioner. However, if you just need things a bit cooler or want to circulate the AC air from a vent around a room more efficiently, it’s a great, nearly silent option.
Dyson Pure Hot+Cool™ HP01 Air Purifier, Heater & Fan - White/Silver
Cools efficiently and also works as an air purifier.
Best Pillow: Coop Home Goods Eden
A pillow can trap heat and make you feel warmer than you’d like. The Coop Home Goods Eden Adjustable Pillow is made of cooling, gel-infused memory foam and a microfiber fill blend. This combination cuts down heat-retention so you’ll feel much cooler than with a traditional pillow.
It’s also truly adjustable and versatile. You can add or remove the fill via the zipper on the side depending on how fluffy you want it to be. We found this pillow is neither too firm, nor too soft, and really does provide a cooling effect.

Made of gel-infused memory foam that won't trap heat.
Best Mattress Pad: Slumber Cloud Nacreous

When it comes to cooling mattress pads, it’s tough to beat the Slumber Cloud Nacreous. It’s made specifically to reduce heat and moisture buildup. It also reacts to each person’s sleep temperature.
The thermal-regulating material absorbs and releases heat to keep your body temperature stable. It can even cool down hot mattresses by allowing greater airflow so the heat can escape from underneath you. If you’ve been considering replacing your entire mattress, you might want to try this first.
The lining fabric is heavily coated with space-aged Outlast® technology, which is what’s used in NASA spacesuits to help astronauts stay cool. It’s made up of thousands of microscopic beads that counter temperature fluctuations and absorb and store excess heat. If you get too cool, the beads will release the heat to keep you comfortable.
Best Bed Cooler: chiliPAD Sleep System

While the NASA-inspired, passive-cooling technology of our previous suggestion is tough to beat, active cooling can do it. The Chili company makes systems that pipe water through thin tubes in a plush mattress pad.
It works much like a heated mattress pad, only instead of adding heat with electrical wires, it removes it with the help of an exchanger (shown in the image above). This device sits on the floor of your bedroom.
The original chiliPAD Sleep System consists of a hydro-powered mattress pad, thermal-regulating control unit, and a remote. It regulates the temperature of your bed and will keep it comfortably cool when you add water to the control unit and use it with the mattress pad.
The more advanced Ooler System combines the original design with a better cooler and app integration. The app not only replaces the remote control, but also features a helpful sleep schedule. This allows you to customize your sleeping and waking routines using temperature-based cues.
