I've done my research about polyphasic sleep many times during my lifetime. When I was 15 years old I started sleeping for 4h + two 20 minutes naps, and everything went okay.
Right now I am 22 years old, and I failed to achieve polyphasic sleep. My ideal recipe is 6.5h + 16min nap. But I'm not entirely sure about that.
However, following my constant research trying to beat sleep, and so having more time to increase my productivity, I have concluded that no, polyphasic sleep is not good for you, we need to sleep for the 6-9 hours range that we always have heard about.
As I think the "It works for me" says nothing, I have been doing my research on the topic.
I have found no real evidence supporting polyphasic sleep. There are many famous cases of people who have achieved to break our sleeping routine, but there's no consistent paper or research made over a relevant population; by contrast, we do have evidence of the negative consequences of not getting enough sleep.
In opposition to the simple "many mammals sleep several times a day" argument, I dare say human brain is more complex than any one of other species, as well as our memorization and learning processes, making extrapolation from a our dog or a primate a tricky task; at least when it comes to focusing on a subject or knowledge retention.
I must also say that evidence shows that, for the majority of the people, after several periods of sleep deprivation, you start to feel fresh and awesome, but inside of you, your brain performance is decreasing, even if you feel lucid -that would be a false sensation-. Nevertheless, a small percentage of the world population is able to get through the day with less hours of sleep. [http://www.businessinsider.com/people-who-sleep-short-hours-2015-11]
Besides how many hours we have to sleep, it seems like we, Spaniards are doing well: naps are good for you. Numerous studies claim the positive effects of napping. Although almost every one of them suggest naps should not last too long (in my case, the aforementioned 16 minutes).
Finally, I have to say the the "8 hours myth" is that, a myth. The vast majority of humans need to sleep between 6 to 9 hours per day, and not the classical and "stiff" 8 hours. [https://blog.bufferapp.com/how-much-sleep-do-we-really-need-to-work-productively]
That said... Let's go to sleep!
