Until there's more research studying the long term effects of this, I really don't think it's a good idea.
Current research has identified that conventional sleeping helps memory, learning, creativity, and muscle repair/recovery (related to working out); not sleeping well can lead to stuff like high blood pressure and the hardening of heart arteries (which leads to heart attacks).
Then again if you don't have much of a choice if you have a hard deadline, this may be a useful tool to use now and again.
Polyphasic sleep != sleep deprivation unless it is not done correctly. Yes, not sleeping well (deprivation) can cause those things, but it does not mean that polyphasic sleep causes them. if you have adapted and are on a consistent schedule, you should be more rested than before.
