Mattress sizes are shown by different words like a queen, a king, a full, double, and so on. No matter whether the inside material is memory foam, feather, or any other material. Are you considering a memory foam mattress or a similar product? Read what the sleep experts have to say about it. Few things are as good as a good night's sleep. This is especially true when your sleep seems to be slipping away every night. If you've ever heard of memory foam, you may be wondering if it can improve the quality of your sleep. Some people swear by it. Others are less enthusiastic. 
What exactly is the shape of memory foam? What are the pros and cons? Here's some information to help you decide if it's worth trying a memory foam. What is the shape of memory foam? Shape memory foam was first developed in the mid-1960s for NASA's aviation seats and is made of a material called viscoelastic. It is very energy-intensive and soft. Shape memory foam conforms to your body in response to heat and pressure, and distributes body weight evenly. After the pressure is released, it returns to its original shape. These properties, in addition to impact protection, make the memory foam very comfortable. After NASA's "first flight", memory foam moved into other applications. For example, it was used as a lining in caps and shoes. Medicine has found applications for prostheses and pressure ulcer prevention products such as seat cushions for people with severe disabilities. So, the memory foam is really gone. Today it is known for use in pillows, mattress protectors, and mattresses of various densities and depths. What are the benefits of shape memory foam? Can the special properties of memory foam improve your sleep? dr. Donna L. Aran, a sleep specialist, says there is no objective research supporting the purported benefits of memory foam or the effect of any particular type of sleeping surface. 
He says there are several reasons for this. This type of sleep test can be expensive if done alone. Or if it is backed by the industry, it is influenced by bias. In addition, some sleep technologies, such as memory foam, are relatively new and have not been well researched. But perhaps one of the most difficult hurdles to testing the health benefits of mattresses like memory foam is the subjective nature of sleep. It's just hard to measure. Sometimes the brain's electrical activity, as measured by an electroencephalogram (EEG) and other results recorded during a sleep test, does not always match the subjective experience of a person, says Aran, clinical director of the Kettering Sleep Disorder Center in Dayton. Ohio "They may say," I slept well, "but my EEG parameters may not be. Aran says sleep is not only subjective but also preferences for individual sleep levels. "There is a difference between people when it comes to the surface they prefer to sleep on, whether it's hard, hard, or soft," she says. As far as we know, there is no rhyme or reason for it. Many Arendt patients who use memory foam have unwanted, radiant messages, such as the one about memory foam: "I sleep well." "Best dream I've ever had." "I like going to sleep at night," Arendt says these anecdotal reactions can be one-sided. This is because they and other staff do not ask all patients about their sleep levels. "Maybe we only hear good things," says Aran. 
- Kathy R. Grommer, a sleep specialist at the Minnesota Sleep Institute in Minneapolis, agrees that memory foam can improve sleep. "It can ease painful pressure points," he says. Grommer adds that memory foam doesn't work for sleep apnea or other respiratory-related sleep disorders - and sleep disorders are the biggest problem for most of his patients.
“When you lie on a memory foam, your body heat softens it in all the right places so it supports your body along the natural curves and contours of your body,” says Aran. Shape memory foam manufacturers say the memory foam helps relieve pain, resulting in more restful sleep. And while consumers generally believe that extra-firm mattresses are the best, more "forgiving" mattresses like these can lead to better sleep in people with back pain, according to the National Sleep Foundation. While there is no scientific data to support this hypothesis, Aran questions whether the shape of memory foam sleeping surfaces may be particularly beneficial for the elderly. For them, minimizing the extra exercise may reduce the number of nighttime awakenings. As an added benefit, you may be less aware of your bed partner's movements, she adds. “No liner and no movement you and your partner feel while sleep." What are the disadvantages of memory foam? Memory foam products can trap body heat and become more comfortable in hot weather, Grommer says. But Aran did not hear this complaint from his patients. "In our culture, most people can adjust their thermostat or their blankets according to the season," Aran says. 
The new form of memory foam can produce a strange chemical smell - a phenomenon called off-gassing. To minimize this problem, the Sleep Product Safety Council, a sleep products trade group, recommends airing out your mattress or pillow for at least 24 hours before putting sheets on it. "If you follow the directions, the smell goes away quickly," says Arndt. But I never heard anyone answer him. Are memory foam products safe for young children? "I recommend avoiding these and other very soft crib materials," says Groomer. This is because soft bedding retains [carbon dioxide] and increases the risk of death from sudden infant death syndrome (SIDS).
