As you prepare for sleep, your body temperature gradually drops, and normal functions, like digestion, slow down. During sleep, your body adjusts to the temperature of the room. However, if your current mattress doesn’t have any cooling materials, the body’s temperature can quickly rise, leading to sleep disruptions.Some types of sleepers run hot, like plus-size sleepers and people with certain medical conditions.Hot SleepersHot sleepers naturally run hot, whether due to gender, age, or other minor reasons. For example, men run hotter than women, because women have a slower metabolic rate—men burn calories quicker than women, heating up their body.Plus-Size SleepersPlus-size sleepers have more body weight, and tend to retain more heat in two ways: overweight people tend to sink more in a mattress, especially if the bed is softer than a medium firmness, trapping more heat. Plus-size sleepers also use more energy to move at night, giving off more heat.Medical ConditionsSome pre-existing medical conditions may cause overheating, like chronic back pain—a herniated disc, for example, may damage and cause nerves and muscles to become inflamed, leading to increased body temperature. Cooling properties can reduce inflammation in affected areas and may also improve blood circulation.What to Look for in the Best Cooling MattressSleeping cool may improve sleep quality, because it leads to less sleep disruptions from overheating. To find your best mattress, consider mattress type, mattress cover, sleeping position, body weight, and available sleep trials, return policies, and warranties.Mattress TypeEach type has a distinct feel. Some customers prefer the hug-like sensation of memory foam, while others prefer the bouncier surface of an innerspring.Memory FoamMemory foam mattresses are popular due to their conforming properties. Heat and pressure cause memory foam to soften, forming to the body’s natural curves to relieve pressure points.A significant drawback to a traditional memory foam mattress is heat retention—the dense structure restricts airflow, causing heat traps. Better options are memory foam beds with cooling materials, like plant-based, gel, and copper and graphite infusions.Plant-BasedPlant oils partially replace petroleum during the manufacturing process, producing a breathable, responsive memory foam.GelCooling gel is swirled or mixed in during the manufacturing process. The gel absorbs and disperses body heat.Copper and Graphite InfusionsCopper and graphite are natural heat conductors, drawing heat away from the body. Copper is also antimicrobial.InnerspringInnerspring mattresses are common in households across the country. Innersprings have bounce, edge support, and cooling; in fact, innerspring mattresses offer the best airflow inside because of their open structure—it enables better airflow inside the bed for optimal cooling. Despite better airflow, innersprings offer very little pressure relief because they lack a thick enough comfort layer, and they transfer motion more than other mattress types.LatexLatex foam shares similarities with memory foam—conforming pressure relief and motion isolation. Unlike memory foam, latex mattresses have a responsive bounce and sleeps cooler. There are two types of latex: synthetic and natural. Synthetic latex is made through a chemical process and retains more heat, but natural latex is created one of two ways from rubber tree sap.DunlopDunlop latex is denser and more durable than Talalay and doesn’t have any added chemicals.TalalayIt contains natural latex and polyurethane fillers to create its signature sponge-like feel. Talalay latex is softer than Dunlop.Latex mattresses can be expensive, depending on how much natural latex they contain, and might be heavy, making them difficult to move.HybridHybrid mattresses contain both memory foam or latex and innerspring coils, forming the perfect bed. While there are many beds containing foam and coils that claim to be a hybrid, a true hybrid mattress has at least 2 inches of foam in the comfort layer. Natural latex or gel memory foam combined with innerspring coils pulls heat away and enables better airflow inside the mattressHybrids offer the benefits of both mattress types, including pressure relief, motion isolation, bounce, and cooling. But, they also have drawbacks, like heat retention, motion transfer, and less pressure relief. Due to the number of materials and layers they contain, hybrid mattresses can be very heavy and difficult to move. They’re also one of the most expensive mattress types.Mattress CoverIf a mattress company markets their beds as having “cooling materials,” that can also apply to the mattress cover. Cotton and polyester are more breathable and may help lower body temperature at night.If the cover is quilted or non-quilted can also affect temperature regulation. Quilted covers thicker and plusher and may feature a thin pillow top. While this may provide extra cushioning, it also means the body sinks more into the bed, trapping heat.Non-quilted covers are thinner and sleep cooler because they encourage better air circulation. They’re less likely to cause overheating.Sleeping PositionConsider your preferred sleeping position before choosing the best mattress. Each sleep position needs a specific level of comfort and support to keep the spine aligned and prevent pressure buildup.Side SleepingSide sleeping is the most common sleep position and the healthiest, reducing acid reflux, improving heart health, and enabling better breathing.The best mattress for side sleepers is a soft to medium mattress for maximum pressure point relief in the shoulders and hips.Back SleepingBack sleeping allows the spine to rest in a neutral position for better alignment. Back sleepers may face a higher risk of developing sleep apnea or snoring due to gravity—gravity may cause the collapse of soft tissue at the back of the throat, or the tongue to fall back, obstructing the airways.Back sleepers need a medium to firm mattress to maintain neutral alignment and prevent the hips from sinking down too far.Stomach SleepingStomach sleeping is the least common sleep position because not many are comfortable lying on their stomachs at night. Stomach sleeping is also tied to health risks—increased spinal pressure can lead to neck strain and back pain, though placing a thin pillow under the hips can reduce this pressure.The best mattress for stomach sleepers will have a medium-firm to firm feel, keeping the body resting on top with no deep sinkage.Combination SleepingCombination sleepers regularly toss and turn, switching between two to three sleep positions each night. Combination sleepers enjoy all the benefits of each sleep position, including better breathing and natural alignment, but combination sleeping also comes with drawbacks, like developing sleep apnea and back pain.Combination sleepers need a medium to medium-firm mattress for a balance of comfort and support and maintain spinal alignment.Body WeightBody weight is another significant factor to consider when looking for a new mattress. Each body type needs a specific level of comfort and support to relieve pressure points and support the spine.LightLight sleepers weigh less than 130 pounds. They need a softer mattress to relieve pressure in heavier sections of the body, like the shoulders and hips.AverageAverage sleepers weigh between 130 to 230 pounds. A medium surface is best in providing even comfort and support, without feeling too soft or too firm.HeavyHeavy people weigh more than 230 pounds and find the best comfort in a firmer surface—a firmer mattress gives better support without the risk of sagging.Sleep Trials, Return Policies, and WarrantiesSleep trials, return policies, and warranties give potential customers an idea of how long a mattress will last. These perks also protect the mattress from damages.Sleep TrialA sleep trial allows customers to try a new mattress within the comfort of their own home. Sleep trials last between 90 to 120 nights, though some mattress companies may require customers to keep the mattress at least 30 days before accepting any returns. Sleep trials are more common with bed-in-a-box brands than in-store retailers. Most companies will pick up and donate the bed before issuing a full refund if the customer doesn’t like the mattress.Return PolicyA return policy is a good substitute if a sleep trial isn’t offered, though the trial period is shorter. Return policies last 30 days—about the time it may take the body to adjust to a new sleep surface. The customer can return the mattress for a refund, but read the fine print first before buying a bed without a sleep trial—some mattress retailers only accept unopened mattresses.WarrantyA warranty protects a new mattress from manufacturing defects and sagging greater than 1 inch (measurement depends on mattress brand). Most mattresses come with a standard 10-year warranty and it only applies to the original purchaser.Other Things to ConsiderWhat mattress material is the coolest?While memory foam can sometimes trap heat, latex foam is a naturally cooling mattress material. Also, mattresses with inner coil systems allow for better airflow than all-foam beds. Hybrid mattresses with latex comfort layers are probably the coolest mattress options out there.Do cooling gels and technologies work?Yes and no. Cooling gels feel cool to the touch for an hour or so after climbing into bed, but by the middle of the night, these cooling gels often feel as warm as the rest of the mattress. Air channels in mattresses are a bit more effective because they actually improve airflow and offer passageways for hot air to escape out of the mattress.What is the best mattress for night sweats?Night sweats can occur as a result of illnesses, like cancer, medical conditions, or from taking certain medications, like anti-depressants. To avoid sleep disruptions from night sweats, choose memory foam beds with cooling materials or hybrid mattresses. Gel memory foam absorbs and disperses body heat, while innerspring coils circulate more air inside the mattress.How can I keep my bed cool at night?If buying a new mattress isn’t within your means right now, using cooling bedding or accessories may help you sleep better. Choose bed sheets and pajamas made of breathable materials, like cotton, bamboo, or linen. Adding a gel memory foam mattress pad or topper can also prevent overheating.Does putting ice in front of a fan work?For those trying to keep their room cool at night, especially during the hot summer months, a bowl of ice with a running fan can be just the trick. This cooling alternative works well for those without air conditioning. Place a container of ice in front of an electric fan. The fan blows cold air rising off the ice cubes towards your direction.ConclusionIf you wake at night feeling hot and sweaty even after switching out your bedding, the problem could be your mattress. A mattress with gel memory foam, natural latex, or innerspring coils increases airflow inside the bed and pulls heat away from the body. For a comfortable night’s sleep, a cooling mattress could be the solution.This article is for informational purposes and should not replace advice from your doctor or other medical professional.
