DEEP SLEEP - THE ULTIMATE GOAL
Researchers at The Karolinska Institute, the prestigious medical university that awards the Nobel Prize in Physiology and Medicine, performed a study investigating the effect different types of mattresses had on the body and sleep quality.
Their results showed that those who slept on a DUX bed not only fall asleep faster, but remained in deep sleep longer – a good thing since deep sleep has been proven to be the only sleep stage where muscles can heal and repair themselves.
In an independent sleep study conducted by the Karolinska Institute of Sweden, the sleep patterns of individuals using a variety of innerspring mattresses were measured using an EEG to record the electrical activity in the cerebral cortex of the brain. The study demonstrated that DUX users not only reached the Deep Sleep stage of sleep faster, but remained there longer. This is especially beneficial since it is during Deep Sleep that the body and immune system recovers and repairs itself.
