Memory foam responds to temperature changes, molding to the body’s contours and providing support at pressure points. It can improve sleep quality and alleviate chronic back pain. Memory foam was developed for the space program but cannot be used due to trace gases. Investing in memory foam pillows can be a good way to test if a memory foam mattress is worth the cost.
Memory foam is basically an insulating material that responds to changes in temperature. When the foam contacts something warmer, the foam realigns itself to provide cushion, softening where the body raises the temperature of the foam. When used in a mattress, it molds to the contours of the human body, providing excellent support at pressure points along the spine, legs and elsewhere. This avoids some of the stresses on the skeletal and muscular systems of the body that are sustained during sleep on any other type of surface. As a person changes position, the foam automatically realigns itself to maintain the cushion effect.
With the pressure distributed evenly throughout the body, there is less chance of waking up to find a more comfortable position. The end result is that you can achieve deep REM sleep, which is the most restorative form of sleep. People with chronic back problems often find that using a memory foam mattress is especially helpful for pain relief.
Although there are several excellent mattresses made with this material on the market today, the most effective models can be expensive. One way to find out if one can be a good solution to sleep problems is to invest in a set of memory foam pillows. If the user finds that the pillows seem to help them get more restful sleep, then purchasing a mattress made from the material would be the next logical step.
The development of memory foam happened because of the space program in the United States. The idea was to find ways to alleviate the adverse effects of acceleration and deceleration periods for astronauts in flight. Unfortunately, the foam that was ultimately created cannot be used for this purpose, as it gives off trace gases that would accumulate in the ship’s enclosed atmosphere. The result of all this research has been a product that is ideal for use in other ways.
