Polyphasic Sleep

[Excelsius]

I posted this thread in Steve's section, but since I don't know when or if he will answer it, I was told to post it in this section in hopes of getting some answers.

Here are the questions:

1. What is the effect of rigorous physical activity (e.g., gym, sex...) on polyphasic sleep? Do you get excessively tired?

2.If you don't have a flexible schedule, does biphasic sleep work (1.5 hours long, once every 12 hours)?

3. Is it wrong to use caffeine during the first difficult week of getting used to this new sleep cycle?

4. I have read that polyphasic sleep does not work when one is trying to carry out overtly intellectual activities: studying physics, differential equations, organic chemistry... Did you have ANY such experiences when you were practicing polyphasic sleep and what was your impression? Please be honest here. If you have not studied complex science while on poly cycle, you can't answer this question.



I also read that many of you sleep 8 or more hours. I was sort of surprised. At most, I sleep 7 hours a night. Nevertheless, I never drink any coffee.

I have found out something interesting in my experimentation with biphasic sleep: usually drowsiness begins to strike me around 11-12am. I tried to take half a caffeine pill (100mg) around this time to cope with the new cycle. Then I discovered that I could easily stay up till 2AM (or 4AM if I took the second half as well) and wake up around 6AM in the morning completely rested and full of energy. I have been doing this for a few days only, but if I can do this for months without ever getting tired, then perhaps this is way better than polyphasic or biphasic sleep? Since I'm already getting around 4hrs/night without any inconveniences, it doesn't seem to be worth it to go to polyphasic sleep to save just an extra hour a night (but I wish I could if I had a flexible schedule)
