Why Night Sweats Happen and How Mattresses Can Help
Night sweats occur when your body’s natural temperature regulation system gets disrupted. Your core body temperature naturally drops as you fall asleep, but certain mattresses trap heat and prevent this cooling process from happening effectively.
Traditional memory foam mattresses are notorious for sleeping hot because they contour closely to your body, reducing airflow and trapping heat. However, the best cooling mattresses use advanced materials and design features to actively draw heat away from your body and promote air circulation.
The key is finding a mattress that doesn’t just avoid trapping heat, but actually helps your body maintain its ideal sleeping temperature throughout the night. This involves materials that conduct heat away from your body, construction that promotes airflow, and sometimes even active cooling technologies.
Detailed Reviews: Best Cooling Mattresses for Night Sweats
Purple NewDay Mattress - Best Overall
The Purple NewDay Mattress stands out as our top pick thanks to its innovative GelFlex Grid technology. This unique gel polymer grid creates hundreds of air channels that promote consistent airflow while providing responsive support.
What makes this mattress exceptional for night sweats is the grid’s open design. Unlike traditional foam that can trap heat, the Purple grid allows air to flow freely through the mattress. The gel material also actively conducts heat away from your body, creating a notably cooler sleep surface.
The NewDay model features three zones of varying grid thickness, providing targeted support for different areas of your body while maintaining excellent temperature regulation throughout. The grid construction also prevents the sinking feeling that can worsen heat retention in traditional memory foam.
Tempur-Pedic TEMPUR-breeze - Best Memory Foam
For those who love the contouring feel of memory foam but struggle with overheating, the Tempur-Pedic TEMPUR-breeze offers the best of both worlds. This mattress incorporates multiple cooling technologies into Tempur-Pedic’s famous pressure-relieving foam.
The TEMPUR-breeze features a cool-to-the-touch cover that feels noticeably cooler when you first lie down. The top layer contains phase change materials that absorb excess heat and help maintain a consistent sleep temperature. Below that, the TEMPUR-CM+ material provides the classic contouring comfort while incorporating cooling gel particles.
This mattress excels at initial cooling and maintaining comfortable temperatures throughout the night. While it’s an investment, the combination of Tempur-Pedic’s renowned durability and advanced cooling makes it worthwhile for serious hot sleepers who prefer memory foam comfort.
Nectar Premier Copper - Best Value
The Nectar Premier Copper proves that effective cooling doesn’t have to break the bank. This mattress infuses copper particles into its memory foam layers, taking advantage of copper’s natural heat-conducting properties.
Copper has been used for centuries in cooling applications, and its integration into mattress foam helps draw heat away from your body more effectively than traditional memory foam. The Premier Copper also features a breathable cover designed to enhance airflow and a supportive base layer that prevents heat buildup.
What sets this mattress apart in the value category is Nectar’s generous sleep trial and warranty, combined with cooling performance that rivals much more expensive options. The copper infusion also provides natural antimicrobial benefits, keeping your sleep environment fresher.
Saatva Solaire Adjustable - Best Hybrid
The Saatva Solaire Adjustable combines the cooling benefits of innerspring construction with customizable firmness levels. This hybrid design naturally promotes airflow through its coil system while offering the ability to adjust firmness based on your preferences and body temperature needs.
The adjustable air chambers allow you to find the perfect balance between support and pressure relief, which can significantly impact sleep temperature. Softer settings may feel warmer due to increased body contouring, while firmer settings promote better airflow around your body.
The Solaire’s organic cotton cover and natural latex comfort layer provide additional cooling benefits. Latex is naturally more breathable than memory foam, and the organic materials avoid the chemical smell and heat retention often associated with synthetic materials.
Naturepedic Verse Organic - Best Natural
For eco-conscious hot sleepers, the Naturepedic Verse Organic offers effective cooling using only natural, organic materials. This mattress combines organic latex with individually wrapped coils for excellent temperature regulation without synthetic cooling technologies.
Organic latex is naturally breathable and responsive, providing cooling comfort without the heat retention of memory foam. The individually wrapped coils enhance airflow throughout the mattress while providing excellent support and motion isolation.
The organic cotton cover is grown without harmful chemicals and processed without flame retardants, which can sometimes contribute to heat retention and off-gassing. This makes it an excellent choice for people with chemical sensitivities who also struggle with night sweats.
Sleep Number Climate360 Smart - Best Firm
The Sleep Number Climate360 Smart takes cooling technology to the next level with active temperature regulation. This smart mattress can actually sense when you’re getting too warm and automatically adjust to help cool you down.
The Climate360 technology includes a cooling layer that can actively lower the surface temperature of your side of the bed. You can control this through the Sleep Number app, setting your ideal temperature and letting the mattress maintain it throughout the night.
This mattress is particularly beneficial for couples where one partner sleeps hot and the other sleeps cold, as each side can be controlled independently. The dual-zone temperature control eliminates the compromise typically required in traditional mattresses.
What to Look for in a Cooling Mattress for Night Sweats
Construction and Materials
The foundation of any good cooling mattress lies in its construction and materials. Look for mattresses that use naturally breathable materials like latex, cotton, and wool. These materials wick moisture away from your body and allow air to circulate freely.
Avoid traditional memory foam unless it’s specifically designed with cooling technology. Instead, opt for gel-infused foams, copper-infused materials, or alternative materials like the Purple gel grid that don’t trap heat.
Innerspring and hybrid constructions generally sleep cooler than all-foam mattresses because the coil systems create natural air channels. However, the comfort layers on top still play a crucial role in temperature regulation.
Firmness Level
Mattress firmness significantly impacts sleep temperature. Firmer mattresses typically sleep cooler because they don’t allow your body to sink in as deeply, maintaining better airflow around your body. However, the best cooling mattresses can provide temperature regulation across different firmness levels.
Medium-firm to firm mattresses are generally recommended for hot sleepers, but personal preference and sleeping position should also be considered. Side sleepers may need softer surfaces for pressure relief, making cooling technology even more important.
Cover and Top Layer Technology
The mattress cover and top comfort layer are your first line of defense against overheating. Look for covers made from moisture-wicking materials like bamboo, Tencel, or specially designed cooling fabrics.
Phase change materials (PCMs) in the cover or top layer can provide active cooling by absorbing excess heat when you’re warm and releasing it when you cool down. These materials help maintain a consistent sleep temperature throughout the night.
Breathability and Airflow
Proper airflow is essential for temperature regulation. Look for mattresses with perforated foam layers, open-cell foam construction, or built-in air channels. These features allow air to circulate through the mattress, preventing heat buildup.
The mattress foundation also plays a role in breathability. Platform beds with slats or adjustable bases that allow air circulation under the mattress can enhance cooling performance.
Additional Tips for Hot Sleepers
Room Environment
Even the best cooling mattress for night sweats can’t overcome a hot, stuffy bedroom. Maintain your bedroom temperature between 65-68°F (18-20°C) for optimal sleep. Use fans, air conditioning, or open windows to promote air circulation.
Consider using moisture-wicking sheets made from bamboo, linen, or specially designed cooling fabrics. Avoid flannel and heavy comforters that can trap heat, even with a cooling mattress.
Lifestyle Factors
Certain lifestyle factors can worsen night sweats. Avoid large meals, alcohol, caffeine, and spicy foods close to bedtime, as these can raise your body temperature. Regular exercise can help regulate your body’s temperature control system, but avoid vigorous workouts close to bedtime.
Stay hydrated throughout the day, but avoid drinking large amounts of fluids right before bed to prevent disruptive bathroom trips that can interfere with your body’s natural cooling process.
Bedding and Accessories
Complement your cooling mattress with the right bedding accessories. Cooling pillows made from gel-infused foam or latex can prevent heat buildup around your head and neck. Look for pillowcases made from cooling fabrics like bamboo or Tencel.
Consider a mattress protector specifically designed for cooling. Some feature cooling fabrics or moisture-wicking properties that can enhance your mattress’s cooling performance while protecting your investment.
Bottom Line: Finding Your Perfect Cooling Mattress
The best cooling mattress for night sweats depends on your specific needs, preferences, and budget. The Purple NewDay Mattress offers innovative cooling technology that works for most hot sleepers, while the Tempur-Pedic TEMPUR-breeze provides cooling comfort for memory foam lovers.
Budget-conscious shoppers will find excellent cooling performance in the Nectar Premier Copper, while those seeking natural materials should consider the Naturepedic Verse Organic.
