A memory foam pillow.
Memory foam is basically an insulating material that responds to changes in temperature. As the foam comes into contact with something that is warmer, the foam realigns itself to provide a cushion, softening where the body heats the foam. When used over a mattress, it conforms to the contours of the human body and provides excellent support at pressure points along the spine, legs and elsewhere. This makes it possible to avoid some of the stresses on the body’s muscular and skeletal systems that occur during sleep on any other type of surface. When a person changes position, the foam automatically realigns itself to maintain the cushioning effect.
Using memory foam can help a person achieve deep REM sleep.
With the pressure evenly distributed throughout the body, there is less chance of waking up to find a more comfortable position. The end result is that deep REM sleep is possible, which is the most restorative form of sleep. People with chronic back problems often find using a memory foam mattress to be particularly helpful in relieving pain.
Memory foam beds are ideal for people with sleep disorders.
While there are several excellent mattresses on the market today that are made from this material, the most effective models can be expensive. One way to find out if one of these might be a good solution to your sleep problems is to invest in a set of memory foam pillows. If the user finds that the pillows seem to be helping them to have a more restful sleep, purchasing a mattress made of this material would be the next logical step.
A memory foam mattress provides great support for the spine.
The development of memory foam came about due to the space program in the United States. The idea was to find ways to mitigate the negative effects of acceleration and deceleration periods for astronauts who were in flight. Unfortunately, the foam that was eventually created could not be used for this purpose, as it gives off traces of gas that would accumulate in the closed atmosphere of the ship. The result of all this research was an ideal product for other uses.
