Just another comment... Polyphasic sleep gives your mind the feeling of rest. You feel ok but the lack of sleep starins your immune system. You are also eating really healthy so you are most likely keeping your immune system up to par, but people that arent eating extremely healthy and want to attemp to sleep in polyphasic mode be weary that you may tend to get sick more often. Also Poly rests the mind as it goes into the REM cycle. The REM cycle is the part of sleep where you get most of your rest. But REm rests the mind. The problem with Poly isnt the short term effects that are harmful but years later. Your body isn't getting enough rest. Your joints will wear out muscles will get used and you will be more likely to have major health problems later on in life. Diabetes, arthritis, osteoporosis and thats just the body. Diabetes would happen because sleep deprivation causes your body to not digest the sugars you eat properly.
I have learned a lot about how the mind regenerates portions lost during the day. Later on in life you could be more prone to memory loss.
There hasn't been much research on this to presuade me to go either way on this. Only personal testimony which is useless.
