Health risks are non-existent? What the heck have you been reading (or better yet, not reading)?

It sure seems like the goal of this sleep regimine is to put your system into continual REM Rebound, which by just about any definition from sleep research equates to "dumb."

All the best research I've read on the topic says that the gold standard is getting whatever your body would require if you allowed yourself a proper night's sleep, which for most people averages a total of 7-8 hours.

REM Rebound aside, shorting your total sleep time by half just puts you into "sleep deprivation." You probably won't notice the effects, since one of the major effects of sleep deprivation is an IQ drop of about 15 points, which will put you into the "too clueless to recognize your confidence for the foolhardiness that it is."
