Thread: Pseudo-polyphasic

I've been trying to separate my sleep time in two periods for quite a while. However, what I found out is that my body doesn't "get" it.

My normal time to sleep is 8 hours, less is not refreshing enough, so I want to separate in two phases, with about 8 hours in between. I do that pretty much every day and I feel bad, because after 4 hours of sleep it's like there were never any more 4 hours of sleep that happened earlier. My body thinks that it's all sleep it got that day!

Then I go to work and back home, sleep some more, and again my body feels like it slept only for 4 hours, disregarding the previous sleep that happened before.

It's like sleep must last uninterrupedly. No matter how much time it lasts uninterruptedly, my body thinks that it's all it got. It doesn't matter that I sleep two times per day, each time is like the only time.

I'd love to hear from people who did something similar and how they experienced it. I heard of polyphasic sleep where sleeping hours are separated from each other, and it's supposed to work and be refreshing, so I wonder what's wrong here.
