Memory Foam Mattress Too Hot? Let’s See Why!

Memory foams are a tremendous pain-relieving source for people who are suffering from body pain. It is specially designed to relieve intense body cramps and back pains. The foam is dense, and it folds to fit your body perfectly. It is the best foam for pressure points; its material is soft and feels comfortable against the skin. However, it can retain a lot of heat and make a person feel uncomfortable and super-hot. So, do memory foams really worth the hype and what are the best ones on the market? Check out here. Let's see why and how these memory foams make you feel hot! 

1. Lack of airflow 

Regular polyurethane foam has an open-cell design. In other words, there are tiny air channels that make such mattresses more breathable. However, that’s not the case with memory foam. This material has a much denser composition and doesn’t really let the air through. And when the air does not circulate, it can’t help dissipate the heat. That’s why memory foam mattresses typically sleep hot.

Reduced airflow also affects the mattress’s ability to wick the excess moisture away. This often causes sleepers to sweat more during the night, which only leads to further heat build-up.

2. Cradling and trapping heat

Memory foam is a visco-elastic material. It responds to applied pressure and body heat, compressing easily and enveloping the body curves. As a result, memory foam has a hugging feel. That much of a hug means that more of the body surface is in contact with the mattress. And this creates more spots where the heat may accumulate. 

In other words, sleepers aren’t only wrapped by the blanket on one side. They are also wrapped by the mattress on the other side, creating a cocoon of warmth. While this may come in handy during colder months, it also causes night sweats when the weather is warm (even if the sleeper decides to ditch the blanket).

Some Ways to Keep Cool On a Memory Foam Mattress

If you have already invested in a memory foam mattress, then you will feel so mad at its overheating property. However, it is not easy to get rid of the mattress as you spend a fortune to buy it. No one wants to give away a mattress that they thought would last them more than a decade. Hence, it is natural to look for remedies to keep cool on a memory foam mattress. Are you looking to cool down memory mattresses too hot? Here are some: 

  1. Change your bed platform. Well, who would have thought changing your bed platform will resolve the hot mattress issues? The mattress solid platform can constrict the airflow significantly. People blame their mattresses for constricted airflow, but the platform can be easily blamed in a real bed. The first step you must take before you blame your mattress for overheating is to check the kind of bed platform you have. You can switch to a slatted base as it helps in better airflow. It helps in removing warmth and moisture from your mattress.

  2. Manage your room’s temperature. If you live in a hot climate, even the best cooling mattress cannot help you. The real culprit is the weather, and you must do something to control your room’s temperature. An air conditioner is the best thing available in the market. If you can, you must save up the money to invest in an air conditioner. If you have a thermostat, adjust its setting to cool. If you do not have even one of the facilities available, try to open your fan and windows. Let the air flow freely into the room and do things to enhance ventilation. The consistent flow of air helps to cool down a memory foam mattress.

  3. Choose breathable sheets. Sheets make a world of difference in making your bed cool or hot. If you use a polyester bed sheet, it is likely to make you feel hot as it traps more heat. A breathable bed sheet is soft, and it feels cold against the skin. A linen sheet feels like heaven in summer, primarily if you use light colors. Lighter color adds freshness to your room and makes everything more vibrant. A sheet with appropriate thread counts to promote airflow is probably a better option to keep your mattress from absorbing heat. Such sheets help in wicking away moisture and sweat.

  4. Mattress pads. One thing that is a must-have for you if you have a memory foam is a mattress pad. A mattress pad helps to make memory foam mattress cooler. It protects the mattress from staining as well as compressing. We love it is ideal for retaining the mattress’s shape. If you are looking to keep cool in a memory foam mattress, a gel-coated or cotton pad is perfect. They help in wicking moisture and heat from the mattress. The mattress pad does not let the heat go deeper but rather dissipate faster.

  5. Change your clothes. Sometimes people can feel hot on a mattress without memory foam due to the type of clothes they wear to sleep. If you wear a polyester pajama or jeans set to sleep, you will feel hot. Hence, it is essential to invest in some breathable linen or cotton pajama set. It is necessary to make sure you change in your night suit before going to bed. The memory foam should not always be blamed for leaving you all hot and bothered. Sometimes, it’s the poor choice of a pajama set or rather sleep-wear fabric. Want a mattress without memory foam? Check out here!
