I called Nationwide Medical after my current CPAP supplier was no longer an approved Medicare vendor. I gave all my information to the man I spoke to, including the model and serial numbers of the machine I was using, my doctor's names and phone numbers, and my Medicare number.
REM rebound. REM rebound is the lengthening and increasing frequency and depth of rapid eye movement (REM) sleep which occurs after periods of sleep deprivation. When people have been prevented from experiencing REM, they take less time than usual to attain the REM state.
Like deep sleep, REM sleep is associated with increased production of proteins. One study found that REM sleep affects learning of certain mental skills. People taught a skill and then deprived of non-REM sleep could recall what they had learned after sleeping, while people deprived of REM sleep could not.
