How To Cool A Memory Foam Mattress: 7 Effective Tips for Hot Sleepers

Memory foam mattresses are beloved for their pressure-relieving comfort and body-contouring support that an innerspring mattress doesn’t necessarily provide, but they’re also less fondly known for retaining heat. If you’re a hot sleeper who’s been waking up sweaty or tossing and turning due to an uncomfortably warm sleep environment, we have good news: you don’t have to give up your comfortable foam mattress to achieve cooler sleep.

This comprehensive guide walks you through seven simple methods to cool your memory foam mattress, from strategic bedding choices to room optimization techniques. As sleep specialists and manufacturers of premium sleep solutions, including advanced cooling mattresses, AirPedic™ brings you expert-backed solutions that can transform your hot sleep experience into refreshing, restorative rest without requiring a complete mattress replacement.

Tip 1: Use a Cooling Mattress Topper

A cooling mattress topper offers one of the quickest and most cost-effective solutions for reducing memory foam heat retention. These specialized cooling toppers work by creating a breathable barrier between your body and the heat-trapping foam surface below, immediately improving temperature regulation and sleep quality:

Gel infused memory foam toppers enhance heat dispersion through gel particles that actively draw heat away from your body. The gel material helps maintain a cooler surface temperature while preserving the pressure-relieving benefits you love about memory foam.

Latex foam toppers offer naturally breathable comfort with responsive support thanks to the material’s open-cell structure. This promotes superior airflow and buoyant support without traditional memory foam’s “sinking” sensation or heat retention.

Open-cell foam toppers are engineered with synthetic materials for better ventilation. Unlike traditional memory foam’s closed-cell structure, open-cell designs allow air to move freely through the material, reducing heat buildup significantly.

Copper or graphite-infused foam toppers utilize these materials’ natural thermal conductivity properties to actively transfer heat away from your body. These advanced materials not only cool but also offer antimicrobial benefits for a cleaner sleep environment.

When selecting a cooling topper, ensure its dimensions match the entire surface of your mattress, and remember that the thickness you choose might affect the fit of your sheets. A well-fitted topper provides consistent cooling and adds an extra comfort layer that can extend your mattress’s life while minimizing heat retention issues.

Tip 2: Opt for Breathable Bedding

Regarding your choice of sheets, mattress protectors, and covers play a crucial role in regulating sleep temperature.  Synthetic fabrics tend to trap heat and moisture, but natural fibers offer superior moisture-wicking while promoting airflow around your body:

Cotton sheets, particularly those with a percale weave, offer excellent breathability and moisture management. Percale’s crisp, lightweight feel provides superior airflow compared to sateen weaves, making it ideal for hot sleepers on memory foam surfaces.

Bamboo viscose naturally regulates temperature through moisture-wicking properties and enhanced breathability. This eco-friendly material feels silky smooth while maintaining coolness throughout the night.

Tencel™ Lyocell represents premium cooling bedding technology. Made from sustainably sourced eucalyptus, Tencel naturally regulates temperature, wicks moisture, and inhibits bacterial growth for a consistently clean, cool sleep environment.

Keep these materials in mind for all your bedding layers. The right combination creates multiple airflow channels while protecting your mattress from moisture that could affect its cooling properties over time. For example, AirPedic’s premium sheets and protectors are specifically designed to complement each other, as well as cooling mattress technology for optimal temperature regulation.

Tip 3: Increase Air Circulation in Your Bedroom

Even the most breathable mattress cannot stay cool in a poorly ventilated room. Optimizing airflow throughout your sleep environment significantly reduces heat buildup on and around a memory foam mattress.

Electric fans can dramatically improve bedroom cooling. Strategically position a ceiling fan or oscillating fan so that it creates consistent air movement across your bed. Similarly, a floor fan near the foot of the bed pushes cooler air upward, promoting beneficial air circulation patterns.

Natural ventilation from simply opening windows during cooler evening hours can cool your bedroom before and while you sleep. Cross-ventilation between windows on opposite walls or sides of the house also helps prevent warm air from accumulating around your mattress.

Air purifiers with built-in fans serve dual purposes, improving air quality while enhancing air circulation. Again, position these devices to create gentle airflow patterns that promote cooling.

Be mindful of humidity levels, which can make heat feel more oppressive. In humid climates, a dehumidifier can create a drier environment that feels cooler and more comfortable, even at the same temperature.

Tip 4: Lower Your Bedroom Temperature

The ideal sleep environment maintains temperatures between 60-67°F. Even if your memory foam mattress retains some heat, a cooler room temperature can effectively offset this thermal retention for comfortable sleep.

Thermostat management provides the most direct temperature control. Set your thermostat to a lower temperature an hour before bedtime, allowing your room to reach optimal cooling before encountering any mattress heat retention. Don’t have central air conditioning? A portable unit or swamp cooler can be a boon in hot climates during summer months.

Programmable or smart thermostats can automatically adjust temperatures throughout the night regardless of the season, maintaining consistent coolness without manual intervention. Smart systems can even learn your preferences and adjust accordingly.

Blackout curtains prevent daytime sun from raising room temperatures, which can last well into the evening. Blocking sunlight during peak heat periods keeps your bedroom cooler when bedtime arrives.

Cool-toned room decor in light blues, greens, and whites reflects rather than absorbs heat, contributing to a psychologically and physically cooler environment. Dark colors absorb heat and can make spaces feel warmer.

Running air conditioning, fans, and dehumidifiers for at least an hour before bedtime helps your bedroom reach cooler temperatures before you even slip into your memory foam bed.

Tip 5: Adjust Your Sleeping Position

Your sleeping position significantly affects how your body retains and releases heat on a memory foam surface. Certain positions can trap warmth against the mattress, while others promote better heat dissipation and help even hot sleepers sleep cool.

Back sleeping allows sleeping body heat to dissipate by reducing contact with the mattress surface and promoting natural airflow around your body. It also reduces the deep compression that can increase heat buildup in memory foam.

Side sleeping can be adjusted to improve cooling for those who prefer this sleep position. For example, using a breathable body pillow to create space between your legs helps prevent heat buildup in areas where skin touches skin. 

Avoid stomach sleeping, which presses the entire torso into the mattress, maximizing heat-retaining contact. If you must sleep on your stomach, consider a very thin, cooling pillow to reduce neck strain and heat buildup, and spread out your limbs for less skin contact.

Inclined sleeping helps increase air movement around your upper body. This position promotes cooling and can improve breathing and reduce snoring, especially with an AirPedic adjustable bed base, which enhances both temperature regulation and overall comfort.

Tip 6: Use Cooling Accessories

The right accessories can also bolster your memory foam mattress cooling efforts, targeting specific areas where heat buildup is most problematic.

Cooling pillows address one of the most heat-sensitive areas of your body. Choose from gel memory foam, latex, or specialized cooling fill materials designed to regulate head and neck temperature throughout the night.

A cooling mattress pad offers similar enhanced temperature regulation. These bed accessories often feature phase-change materials or cooling gels that actively manage heat fluctuations.

Lightweight blankets made from natural fabrics and breathable material provide comfort without adding thermal burden. Look for blankets specifically designed for hot sleepers, featuring breathable fabrics and cooling technologies.

Seasonal bedding swaps can optimize your sleep environment year-round. Ultra-lightweight, cooling sheets are ideal during warmer months, as is transitioning to warmer options as desired during cooler seasons.

Consider upgrading multiple accessories simultaneously for a cumulative impact on cooler sleep. The combined effect of cooling pillows, breathable blankets, and temperature-regulating sheets can dramatically improve your sleep experience on memory foam.

Tip 7: Take Care of Your Mattress

Proper mattress maintenance extends the lifespan of any bed, but can also help preserve and even improve the cooling properties of memory foam over time.

Regular rotation every 3-6 months prevents concentrated wear patterns that can create heat-trapping depressions. Even wear distribution maintains memory foam’s ability to allow airflow and prevents the formation of permanent body impressions that retain heat.

Periodic airing benefits memory foam significantly. Strip all bedding and allow your mattress to breathe for several hours, preferably in a well-ventilated room. This process helps release trapped moisture and odors while refreshing the foam’s cellular structure.

This is also an excellent time for gentle vacuuming to remove dust, dead skin cells, and other debris that can clog foam pores and reduce breathability. Use an upholstery attachment and low suction to clean the surface without damaging the foam structure.

Maintaining a clean, dry sleep environment will preserve your mattress’s cooling properties and extend its effective lifespan while ensuring optimal temperature regulation.
