Introduction to Mattresses for Hot Sleepers
If you’re someone who sleeps hot and wakes up drenched in sweat, finding a cooling mattress can be a game-changer for getting better sleep. The right mattress can help hot sleepers like you stay cool and comfortable and get the quality sleep your mind and body need.
This guide will cover everything hot sleepers need to know about finding the best cooling mattress from what causes overheating at night, signs you sleep hot, how it impacts health, and the exact mattress features and types that allow the most airflow and cooling.
Plus we’ll recommend the top mattress brands and beds that keep hot sleepers coolest based on verified customer reviews and policies that let you test them risk-free.
What Causes Excessive Heat at Night?
Many factors can cause someone to sleep excessively hot:
- Body heat production – Metabolism and circulating blood keep the body quite warm throughout the night.
- Room temperature and humidity – The ideal room temperature for sleep is 60 to 67°F with low humidity. Warmer or muggy rooms inhibit cooling.
- Mattress materials retaining heat – Traditional memory foam and certain other foams are known for retaining body heat.
- Medical conditions like thyroid issues, diabetes, or hormone changes
- Medications – Diuretics and hormones can induce hot flashes and night sweats.
- Menopause – Declining estrogen causes 75% of women to experience hot flashes and night sweats.
- Weight and BMI – Excess weight can increase insulation, inflammation, and heat retention.
Paying attention to all these factors is important, but finding an appropriate mattress designed to help you sleep cool and comfortable through the night can make the biggest impact for chronic hot sleepers.
Signs You’re a Hot Sleeper
How do you know if you’re a hot sleeper struggling with overheating rather than waking occasionally warm? Here are the most common signs:
- Waking often to kick off blankets – If you’re layering on blankets to sleep and then stripping them off a few hours later drenched in sweat, you sleep hot.
- Difficulty falling or staying asleep – Tossing and turning trying to get comfortable but feeling too hot is a sign your mattress isn’t cooling you properly.
- Night sweats that soak sheets or pajamas – Hot flash-type night sweats that leave you or your sleep environment wet are a clear sign of overheating.
- Reliance on fans or AC being very cold – If you can’t sleep without a loud fan inches from your face or freezing AC pointing directly at you, your mattress likely retains heat.
- Avoiding certain mattresses or bedding – If certain mattress types like memory foam or flannel sheets cause you to overheat, pay attention and avoid them.
If one or more of these scenarios sounds familiar, then you likely need better cooling and breathability from your sleep setup.
How Sleeping Hot Affects Health and Quality of Sleep
Sleeping hot isn’t just annoying and uncomfortable in the moment. Chronic overheating during sleep can seriously impact both short and long-term health.
Some consequences hot sleepers face include:
- Fatigue and grogginess – Waking up from hot flashes or night sweats leaves you feeling unrested. This carries over into chronic low energy and fatigue.
- Impaired concentration and cognition – Lack of deep REM sleep from disrupted overheated sleep deprives the brain of restoring itself fully each night.
- Increased irritability – Between feeling exhausted yet restless, hot sleepers tend to feel more impatient and irritable.
- Weakened immune system – Inadequate sleep fails to recharge the immune system, leaving you prone to sickness.
- Higher risk for illness and disease – Long-term sleep deprivation from sleeping hot is linked to a higher risk for chronic diseases like heart disease, diabetes, and cancer.
- Weight gain – Fragmented sleep triggers increased appetite and cravings the next day, especially for sugary and salty high-calorie foods. Over time this leads to weight gain.
- Skin aging from dehydration – Losing fluids each night from sweat can lead to dryness, wrinkles, dark circles, and loss of skin elasticity over time.
Sleeping hot negatively impacts health both in the short and long run. Finding a suitable mattress and bedding to maintain an ideal sleeping temperature through the night can solve these issues.
Tips for Cooling Down Beside Your Mattress
While this guide focuses specifically on mattresses for cooling down hot sleepers, it’s worth mentioning a few other habits that can synergize with your new bed to fully solve overheating issues:
- Keep room temperature between 60-67°F
- Choose breathable sheets and bedding made from bamboo, eucalyptus, or other moisture-wicking fabrics
- Sleep separately from a partner whose body heat warms you
- Limit consumption of caffeine, alcohol, and spicy foods several hours before bed
- Take a cool shower 1-2 hours before getting in bed
- Keep the ceiling fan on or use a bed fan to circulate air near your body
- Stay well hydrated by drinking plenty of water during the day and limiting fluids 2 hours before bed to prevent middle-of-the-night bathroom trips
Now let’s dive into choosing the right mattress and foundation to keep you sleeping as cool as can be every single night.
Mattress Qualities to Keep Hot Sleepers Cool
The first step to combatting sleeping hot is being aware of which materials and design factors actually keep you cool vs those that retain heat and moisture leading to feeling sweaty and overheated.
Here are the most important mattress features and characteristics to evaluate when shopping for cooling beds specifically for hot sleepers:
Breathability and airflow – This refers to how well air circulates through the mattress layers instead of getting trapped causing insulation. Models with ventilation channels or chambers allow the most airflow.
Minimal heat retention – You want foams, gels, and other comfort materials that don’t absorb and trap body heat. Advanced phase change materials are ideal as they react to your body temp throughout the night to warm up and then cool off accordingly.
Moisture-wicking and quick-drying – Rather than absorbing sweat and staying damp, ideal mattresses quickly wicked moisture away keeping your sleep space dry and cool through the night.
Advanced cooling technologies – Copper, graphite, titanium, and other new technology infuse mattress foams with natural cooling agents. Open-cell designs further promote cooling.
Generous sleep trial policies – Given how subjective individual sleep needs are, being able to try out the mattress in your unique sleep environment for at least 100 nights is key. Look for full refunds for returns.
Now that you know what to look for in the best mattress for cooling, next, let’s explore the common mattress materials and types you may want to avoid as a hot sleeper.
Mattress Materials to Avoid for Hot Sleepers
Most modern mattresses use some combination of foam, innerspring, latex rubber, or specialty comfort materials. Some options tend to trap heat and moisture leading hot sleepers to wake up sweaty and uncomfortable.
The worst bedding materials for sleeping cool include:
- Memory foam – Known for cradling pressure relief but also notorious for retaining body heat. However, newer technologies like gel infusions and open-cell designs improve breathability.
- Traditional high-density polyfoam – Similar to memory foam, dense petroleum-based foams tend to absorb and trap heat until newer cooling innovations.
- Natural or synthetic latex foam – Provides contouring and responsiveness but can sleep warm due to insulation and humidity if not designed to enhance breathability.
- Low coil count innerspring sets – Many older spring mattresses with thin comfort layers sleep very hot and uncomfortable for most people, especially hot sleepers.
- Fiberfill comfort layers – Found in older mattresses, materials like cotton batting seem soft initially but compress down and retain heat and moisture.
Instead of these dated materials that tend to contribute to sleeping hot throughout the night, newer technologies like copper graphite-infused memory foams paired with pocketed coil support systems promote steady airflow and cooling comfort ideal for those who tend to sleep hot no matter the mattress.
Best Mattress Types for Keeping Cool
Now that you know what features to look for and what materials to avoid when shopping for the best cooling mattress, let’s explore the top mattress types (and a few brands making them right) for providing breathability and temperature-regulating comfort all night long.
For sleepers wanting targeted pressure relief with responsive temperature regulation, a quality latex mattress can sleep quite cool and comfortable thanks to natural airflow through the material and minimal heat retention.
The tiny air pockets within natural or blended latex foam provide buoyant support while facilitating steady airflow. This prevents excessive buildup of body heat common with denser memory and polyfoam layers. Plus latex naturally resists absorbing moisture.
Certain latex mattress brands further enhance cooling by arranging layers into unique zones or layering latex over pocketed support coils for improved overall breathability.
Example latex mattress good for hot sleepers:
Zenhaven – Flippable 100% Talalay Latex Mattress
On its own, an innerspring or coil mattress isn’t enough to provide adequate cooling and comfort. But when paired with the right advanced comfort materials, an innerspring base offers excellent overall airflow and temperature regulation – often better than all-foam beds.
The space within and between hundreds of fabric-encased coils allows for plenty of air circulation. Just be sure to choose quality foams in the comfort system to cover the coils that don’t retain excessive body heat like outdated polyurethane or fiber layers.
Modern innerspring mattresses include gel, latex, graphite infused, or other temperature-regulating foams for cool sleeping comfort night after night.
Examples of innerspring mattresses keeping hot sleepers coolest:
DreamCloud Hybrid Mattress
Winkbed EcoCloud Hybrid Mattress
Hybrid mattresses combine the very best aspects of foam comfort layers and pocketed coil support cores to provide luxurious cooling comfort for even the hottest sleepers.
By pairing open-air pocketed coil layers that facilitate constant airflow with innovative foam and latex materials designed to dissipate heat, hybrid models offer the best of both worlds for keeping you cool.
Advanced technologies like gel infusions, open cell foams, steady airflow chambers, and even cool-to-the-touch covers all help regulate temperatures hour by hour keeping hot sleepers comfortable.

Gel Memory Foam Mattresses
For years, reviewers complained about traditional dense viscoelastic memory foam trapping heat and sleeping uncomfortably hot for many people. In response, mattress companies developed innovative gel-infused memory foam.
Phase change gel materials formulated into memory foam react to your body temperature throughout the night. Gel absorbs heat to warm up initially then releases warmth to cool back off as you sleep keeping airflow and moisture under control.
When shopping for a gel memory foam mattress focus on the density, depth, and quality of the gels used to ensure adequate cooling performance. Be wary of light 1” gel foam layers that won’t offer much relief.

Cooling Mattress Pads and Toppers
If you enjoy your current mattress’s comfort and support but still tend to sleep hot, try adding an upgraded cooling mattress pad or topper before replacing the entire bed.
The best cooling pads and toppers combine moisture-wicking fabrics like poly-cotton, eucalyptus, or bamboo over advanced foams infused with graphite, copper gel and other phase change materials to dissipate heat.
Some pads even include high-tech oscillating fans to facilitate airflow across your entire sleep surface. Cooling toppers should have enhanced airflow through open cell foams and steady ventilation.
