These days, it’s not uncommon to find mattresses designed with materials that allow for more airflow and less heat retention. However, we discovered that not all cooling mattresses are created equal in temperature regulation and ventilation. You shouldn’t limit your search for a cool sleep solution to your mattress. To that end, consider your bedroom as a whole. A variety of the best mattress for side sleepers with back pain and sleeping aids can either help or hinder your efforts to keep a steady temperature throughout the night.
Cooling Mattress Materials
Mattresses can be constructed from a variety of materials. While some help keeps mattresses cool by increasing airflow, others act as thermal blankets. Those who have trouble keeping cool at night could shop confidently for mattresses by knowing which materials are the most breathable.
Key Cooling Materials
- Coils & springs:
Most mattresses have a steel coil or spring system at their centre. Since their layers are so absorbent, they allow air to flow through the mattress and cool the comfort layers above.
- Gel-infused foam:
Some manufacturers inject gel into the memory foam’s comfort layers as a cooling mechanism. However, the degree of success of this strategy is debatable. The design of the mattress, rather than the presence or absence of gel in the memory foam layers, may be more important to consider if you tend to sleep warm.
- Basic memory foam:
The main component of memory foam is polyurethane. When warmed up, it moulds to the shape of the wearer’s body, creating a snug sensation. Additionally, regular memory foam has the propensity to retain heat, making it an unappealing choice for warm sleepers.
- Advanced memory foam:
NASA first developed memory foam to cushion astronauts during space flights. They successfully developed memory foam with innovative features, such as a network of microscopic holes or cooling gel-infused beads.
- Basic polyfoam:
Polyurethane-based polyfoam, commonly used in mattresses, can trap heat similarly to memory foam. Said polyfoam can be used in either the comfort layer or the support core. The main difference between this and memory foam is that it doesn’t conform nearly as much.
- Advanced Polyfoam:
Open-cell polyfoam, also known as advanced polyfoam, is a step up from basic polyfoam. This modern polyfoam features tiny air bubbles or cells that increase breathability and decrease heat absorption. Based on our findings, modern polyfoam mattresses are less likely to retain heat.
If you tend to get too hot when sleeping, you might take some measures to cool down the bedroom. Choosing comfy bedding should be your first order of business. Sheets designed to keep you cool are made of breathable materials like cotton percale, linen, or bamboo rayon to help your mattress release some excess heat it absorbs as you sleep. Alternatively, you might use a cooling mattress pad, which can either be passive or active in its ability to maintain a comfortable temperature while you sleep.
Adjusting the temperature in your bedroom might help you get the most out of the space. According to doctors, the recommended temperature range for a good night’s sleep is between 60 and 67 degrees. Maintaining a comfortable temperature in your bedroom during the summer months can be accomplished with the help of a fan, air conditioner, or swamp cooler.
