Today is the beginning of Day 31 of my polyphasic sleep experiment, so I’ve completed a full 30 days.  This will be my final official log entry on this experiment unless there’s some significant new change down the road.  I consider the experiment a huge success, and I intend to continue with polyphasic sleep indefinitely unless I discover a [...]

Just a few things to report in this polyphasic sleep experiment update. Shifting Perceptions of Time. The sensation that time is passing very slowly that I mentioned in the previous polyphasic log update continues. I’m amazed at how long this weekend seemed to last. To measure time as the passing of days no longer seems [...]

One of the most important (and highly unexpected) developments that recently occurred in my polyphasic sleep experiment was a change in my perception of the passing of time during the naps. When I began this experiment, if I took a 20-minute nap, I’d sleep fairly lightly and awaken feeling that about 20 minutes had passed. [...]

I’ve lasted 3 weeks now on the polyphasic sleep experiment. It’s been quite an amazing experience, and unless some unforeseen roadblocks occur in the weeks ahead, I’ve decided to stick with it. Things I Haven’t Tried. I’ve received several questions about things I haven’t tried, like napping at my desk or eating different foods than [...]

I’ve had some further developments regarding my polyphasic sleep experiment, so I figured an update would be in order. Lucid Dreaming. On Monday night I had another lucid dream during a nap I took just after midnight. This one wasn’t as vivid or as long as the first, but I consider it a significant development [...]

I had made a note on my calendar to write a polyphasic sleep experiment update this morning, so here goes… Today I’m beginning my 18th day on polyphasic sleep. I’ve been able to do a lot more testing and tweaking over the past week, and overall I’ve been very pleased with my progress. Flexibility. I’ve [...]

Since my polyphasic sleep experiment seemed to be going so well, I decided to give it a more difficult test the past few days to get a better sense of its boundaries and limits. This might have been a bit premature, given that I’ve only been at it for a week, but the opportunity was [...]

I just finished my first week on polyphasic sleep. It’s been over 175 hours since my last full night of sleep. Everything is continuing to go well. Today was even better than yesterday. No more brain fog. No more reduced reflexes. I drove the car today for the first time in the past week with [...]

My wife, Erin, has a unique perspective on my polyphasic sleep experiment that she wanted to share, so the rest of this post is from her. You might be wondering what it’s been like to live with Steve while he’s trying his polyphasic sleep experiment. Let me tell you… When he first came to me [...]

Now to address some questions/issues that readers raised with respect to my polyphasic sleep experiment. More Details on Naps: On my polyphasic schedule, I spend about 15-20 minutes asleep during each nap. I set my countdown timer alarm for 30 minutes right when I lie down. It usually takes me 5-10 minutes to fall asleep, [...]
