Waking up hot in your memory foam mattress? Is it making you uncomfortable? Here is why and some remedies.
One of the most common complaints we hear with memory foam mattresses is that they "sleep hot" or rather, that people find they wake up sweating in the mattress. In fact, it is not unusual when showing our customers our foam beds that their first response is "I don't like memory foam."
It is true that most memory foam beds sleep hot. This is due to several factors:
- Most foam beds are very dense, which prevents air flow around your body
- Most foam beds are covered with "microfiber" fabric or some other blend of polyester, which are all made from plastic
- The leading foam mattresses are sold with solid wood box springs which prevent air flow at the bottom of the mattress
To understand why these beds sleep hot, we must first understand where the heat comes from. The heat in your bed comes from your body. At the deepest stage of sleep, your body is quite busy. Here is what is going on:
- Blood pressure lowers
- Breathing becomes slower and deeper
- Muscles relax
- Blood supply to muscles increases
- Tissue growth and repair begins
- Energy is restored
- Hormones are released, such as growth hormones, which are essential for growth and development, including muscle development
With all these processes occurring , the body generates heat and with heat comes sweat. This is where foam beds CAN become an issue. When you are sleeping on foam beds that are constructed with dense foam (too dense in my opinion) and plastic fabrics, the moisture your body generates has no where to go and the heat is trapped. You end up baking and sweating.
Nature devised a brilliant way for our bodies to process heat and moisture: hair. Hair can wick moisture away from the body. As the moisture forms on your skin, it comes in contact with the hair and pulls it up and away from the skin, helping it to evaporate quickly. And of course, hair can keep you insulated in the winter. Plastics are incapable of absorbing moisture so the heat and moisture your body generates in your sleep does not evaporate. Coupled with the lack of air flow, the result is a very hot sleep environment.
At Nest Bedding, we believe foam is one of the most advantageous sleep products, as it can be both supportive and pressure-relieving. It was our mission to find a foam mattress that utilizes natural fibers and more breathable foams, and we found these attributes in Bed In A Box.com foam mattresses, which we gladly and exclusively in our showrooms in Berkeley/Albany Ca and in San Francisco, Ca, and online at www.NestBedding.com.
So, not all memory foam beds will sleep hot. Some are simply designed with you in mind, and not the contents of your wallet. And we back that up with a 4 months 100% money back guarantee!
