Being a hot sleeper has become a surprisingly easy problem to solve. Instead of relying on an open window or a bedside fan, you can now cool your bed with circulating water, temperature-regulating fabrics, wearable cooling tech, or smart home gadgets that help keep your bedroom comfortable all night.
The challenge is figuring out which type of cooling actually fits your sleep setup. That’s why we’ve grouped these gadgets by how they work, making it easier to find the right solution for the way you sleep.

Active Cooling Systems
These systems actively remove heat while you sleep. They also make up the most expensive category, but if you always sleep too hot or regularly wake up drenched in sweat, they’re the products most likely to improve your sleep.
Eight Sleep Pod 5: Best for a Fully Automated Sleep Experience
The Eight Sleep Pod 5 is a sleep operating system that uses a water-filled cover that sits over your existing mattress, continually heating or cooling each side of the bed. Meanwhile, built-in sensors monitor metrics like heart rate, breathing, and movement; if you get warmer during the night, the system automatically adjusts without you touching a button.
It’s impressively hands-off, but the trade-offs are that the system requires occasional water refills, it relies heavily on the companion app, and many of the smartest features live behind an ongoing subscription. But if you love automation and don’t mind a connected ecosystem, it’s one of the most advanced cooling systems currently available.
Chilipad 2.0: Best for Powerful Cooling Without a Subscription
Like Eight Sleep, the Chilipad 2.0 uses circulating water to tweak the temperature of your bed, letting you cool or warm your mattress anywhere between 55°F and 115°F. It’s not automated like Eight Sleep’s offering, but one of its nicest upgrades is the physical bedside remote, so you don’t have to reach for your phone every time you want to adjust the temperature.
You’ll still need to refill the reservoir periodically and perform basic maintenance to keep the system running smoothly, but there are no mandatory subscription fees or locked features. For people who simply want excellent temperature control without regularly paying for software, it’s a compelling alternative.
BedJet 3: Best for People Who Hate Sleeping on Water Tubes
Instead of cooling the mattress itself, the BedJet 3 pushes a steady stream of temperature-controlled air beneath your sheets using a hose tucked under the bed, helping remove heat and humidity before they build up around your body.
Because it’s an air-based system, there’s no water tank to refill or clean, and the maintenance is largely limited to keeping the filter clean. The trade-off is that you’re still cooling with the air that’s already in the room, so the performance depends somewhat on how cool the room is. If the temperature regularly sits above 79°F, BedJet acknowledges that you’ll probably want air conditioning helping out too.
Passive Cooling Materials
Passive cooling relies on clever materials and construction to make it harder for heat to build up in the first place. While these products won’t cool your bed to a specific temperature like an active system can, they’re typically quieter, maintenance-free, and much more affordable.
Dormeo Premium Mattress Topper: Best for Reviving a Hot Memory Foam Mattress
If your mattress feels like it stores heat all day and gives it right back to you at night, the Dormeo Premium Mattress Topper is built around a patented Octaspring design to help cool you, with hundreds of open-cell foam “springs” that create channels for air to circulate throughout the topper.
Every time you roll over or shift position, the springs compress and rebound, helping to push warm air out while drawing cooler room air back in. Dormeo claims the design is up to eight times more breathable than conventional memory foam, making it a solid option for anyone who likes the pressure relief of foam but hates the stuck-in-quicksand feeling that often comes with it.
Helix GlacioTex Mattress Protector: Best for Cooling With Waterproof Protection
A mattress protector might not be the first product you’d think about when you’re trying to sleep cooler. In fact, many waterproof protectors have a reputation for making beds feel warmer, but the Helix GlacioTex Mattress Protector tries to solve that.
Helix uses GlacioTex, a high thermal conductivity fabric designed to pull heat away from your body as soon as you lie down. The cooling sensation is immediate because the fabric conducts heat away from your body more efficiently than standard materials, giving it that cool-to-the-touch feel. At the same time, it still provides waterproof protection against spills and everyday accidents.
The biggest limitation is that conductive fabrics don’t continually remove heat the way active cooling devices do. Once the material reaches the same temperature as your body, the cooling effect becomes less noticeable. Still, if you already love your mattress and simply want a cooler sleep surface, this is a practical upgrade.
Slumber Cloud UltraCool Comforter: Best for Year-Round Temperature Regulation
The Slumber Cloud UltraCool Comforter uses Outlast ClimaDry fibers, a phase-change material originally developed for NASA. Instead of trapping warm air like a traditional comforter, these fibers absorb excess body heat when you’re warm and gradually release it as your body cools later in the night.
That means that the comforter is regulating temperature rather than constantly feeling cold. It also features a silky nylon outer shell with one of the higher published Qmax ratings on the market, meaning it delivers an immediate cool-to-the-touch sensation before the phase-change materials take over.
There’s also no maintenance beyond normal washing, and because the cooling technology is built into the fibers themselves, there’s nothing to recharge or replace. Just keep in mind that even the best comforter can’t compensate for a bedroom that’s already uncomfortably hot.
Quince Organic Crisp Percale Sheets: Best for Breathable Summer Bedding
The Quince Organic Crisp Percale Sheet Set uses a classic one-over, one-under weave that creates a lighter, more breathable fabric than sateen. Instead of feeling silky or heavy, percale has that crisp hotel-sheet feel that lets air circulate more freely around your body.
Breathable sheets won’t fix a mattress that traps heat, but they can make your bed feel noticeably cooler by improving airflow around your body. They’re one of the simplest upgrades you can make, and unlike active cooling systems, they don’t require any maintenance beyond wash day.
Personal Cooling Gadgets
Sometimes, you don’t need full-bed technology to solve your overheating woes. If your pillow feels warm after 20 minutes, your face is flushed, or your back won’t stop radiating heat, that’s where these localized gadgets come in — because they can provide targeted relief exactly where you need it.
Purple Harmony Pillow: Best for Keeping Your Head Cool
If your pillow turns into a heat trap halfway through the night, the Purple Harmony Pillow tackles the problem through ventilation rather than cooling gels. Its signature Honeycomb GelFlex Grid sits over a ventilated Talalay latex core, creating hundreds of open air channels that let heat and moisture escape instead of collecting around your head and neck.
Unlike many cooling pillows that rely on a gel layer that eventually warms up, the Harmony’s open structure keeps air moving whenever you shift position. It also maintains its shape exceptionally well, so you’re not constantly fluffing or redistributing the fill.
Cooling Gel Pad: Best for Quick Relief During Heat Waves
Cooling gel pads aren’t just useful for your beloved pet. They’re especially useful under your calves, lower back, or feet, which is why many people keep one around for particularly hot nights.
The catch is that gel pads have a finite cooling capacity. Once the gel reaches your body temperature, the cooling effect gradually fades until the pad has time to dissipate that heat. It’s a short-term solution rather than all-night climate control, but if you keep a spare in the fridge, you can easily swap the warm one for a cool one. They’re lightweight, portable, and one of the least expensive ways to make a hot night more comfortable.
Manta COOL Sleep Mask: Best for Cooling Your Face Before Bed
The Manta COOL Sleep Mask uses removable cooling gel eye cups that can be chilled in the freezer before bed. The cold stays localized around your eyes, helping soothe tired, puffy eyes while providing a refreshing sensation that many find relaxing before sleep. Cooling your eyes and forehead can also make your whole body feel more comfortable, even if the room temperature hasn’t changed.
Like any reusable cooling pack, the eye cups gradually warm as they absorb heat, so don’t expect them to stay icy until morning. There’s no maintenance beyond placing them back in the refrigerator or freezer before your next use, and the mask itself remains lightweight and travel-friendly.
Embr Wave 2: Best for Hot Flashes and Instant Cooling
The Embr Wave 2 is probably the most unusual gadget here. Worn like a smartwatch, it uses a small thermoelectric module to deliver gentle cooling or warming pulses to the sensitive skin on the inside of your wrist. That localized temperature change influences how your brain perceives your overall body temperature, which is why many describe feeling cooler even though the rest of their environment hasn’t changed.
Because it’s battery-powered, you’ll need to recharge it regularly, and the cooling sensation is intentionally localized rather than widespread. It’s also designed for use throughout the day, making it especially appealing for people dealing with hot flashes or anyone who wants portable cooling.
Smart Bedroom Climate Control
The coolest bed in the world can only do so much if your bedroom still feels like an oven. These gadgets cool the environment around you or stop heat from building up before/during bedtime.
Dreo Smart Tower Fan: Best for Improving Bedroom Airflow
A good fan can make your bedroom feel significantly cooler by moving air across your skin and helping sweat evaporate more efficiently. The Dreo Smart Tower Fan takes that basic idea and adds a few useful upgrades. Through its companion app, you can schedule different fan speeds throughout the night, control it with voice assistants, and set timers so it gradually slows as the room cools toward morning. It also has multiple airflow modes and speeds that feel less like a constant blast of air and more like a natural breeze.
The main consideration is noise. While Dreo fans are designed to run quietly at 20dB, it’s not invisible. That being said, many people love the ambient sound of a fan running in the background.
ecobee Smart Thermostat Premium: Best for Automating Your Bedroom Temperature
The ecobee Smart Thermostat Premium can make sure your bedroom is already at the right temperature before your head even hits the pillow. Instead of remembering to adjust the thermostat every night, you can create schedules that gradually lower the temperature before bedtime, keep the room cool during the night, and warm it back up before your alarm goes off.
One of ecobee’s biggest advantages is its SmartSensor system, which measures the temperature in individual rooms rather than relying solely on the thermostat’s location. That’s particularly helpful if your bedroom is consistently warmer than the rest of the house. It also integrates with Apple HomeKit, Amazon Alexa, Google Assistant, and other smart home platforms, so it fits neatly into existing routines.
Lutron Caséta Smart Shades/Blinds: Best for Keeping the Bedroom Cool Before Bedtime
Your bedroom usually starts heating up way earlier than when you turn in for the night. The Lutron Caséta Smart Shades/Blinds help tackle that problem by preventing solar heat from entering the room in the first place. You can schedule the shades to close automatically during the hottest part of the afternoon, or integrate them with sunrise, sunset, and smart home routines. That means your walls, floors, and mattress absorb less heat throughout the day, leaving the room noticeably cooler by bedtime.
Once installed, maintenance is minimal, and because everything runs automatically, they’re very much a set-it-and-forget-it addition to a smart bedroom.
Building Your Personal Zero-Sweat Sleep Sanctuary
If your mattress feels like it’s storing body heat all night, an active cooling system like the Eight Sleep Pod 5 or Chilipad 2.0 will make the biggest difference. If you’re mostly struggling with trapped heat under the covers, breathable bedding or a BedJet 3 may be all you need. And if it’s your pillow, your face, or the room itself that’s making you uncomfortable, a targeted gadget can often deliver more value than a complete bedroom overhaul.
Don’t feel like you have to settle for just one solution, either. Many sleepers will find best results by mixing and matching these gadgets to build the perfect sleeping environment.
