Memory Foam Will Remember Your Body Heat

Memory foam is a kind of polyurethane polymer with an open-cell structure which is very sensitive to temperature and has special viscoelastic, soft properties and strong absorbability. The memory foam was derived from NASA research which applied this material into shuttle seats to reduce the huge impact on astronauts during spacecraft’s cosmic acceleration from atmosphere improving the protection and comfort for astronauts.

In the long run, memory foam is developed to manufacture into different products in many fields including medical equipment, exercise machines, and domestic beddings. It’s now well known for its use in mattresses, toppers, and pillows - coming in various densities and depths.

Memory foam mattresses have the ability to absorb and disperse body weight. It will mold to the shape of our body as it senses human body temperature through the special warm memory particles, and relieves pressure points, giving our body effective support and comfort. So, on one hand, memory foam “remembers” your body shape, however, on the other hand, it stores your body heat. If you don’t have an air-conditioned home, the temperature of the mattress will raise with your body temperature, which makes you feel hotter while you sleep.

What Causes Overheating on a Memory Foam Mattress?

Soft Material

Thanks to the soft material, memory foam mattresses are able to contour to your body, wrapping you in a soft area. As most part of your body keeps in touch with the mattress and this will restrict air ventilation and trap the heat. And memory foam is not firm enough to make air flow between your body and mattress. In the end, we will sleep hotter on the mattress as the night goes on.

Dense Structure

Featuring a very dense substance, memory foam ensures to provide full body support and luxurious comfort. Due to this dense design, memory foam will keep the mattress warm and does not allow much air to pass through. This will lead to heat being trapped inside the mattress and foam temperature increasing continuously. In the end, we will feel too warm or overheated during the night. The higher the foam density, the higher the heat.

Body Heat

Human beings will produce a lot of heat while sleeping at night even if we don’t move at all. Actually, we may toss and turn several times, this will trigger excessive sweating and cause overheating. We will produce more body heat especially when we sleep with a partner. This will give rise to heat-trapping and increase of temperature, shortening our sleeping time and making us feel hotter and sweaty at last.
