After reading about it and doing some research(google :]) it appears to be nothing more than bad advice, people who do it may feel less tired but their actual cognitive abilities are worse than a normal sleeper.
The same goes for sleeping less, several pages mention that cognitive abilities deteriorate at a steady pace when you sleep for 6 hours rather than 8, and even more dramatically if you sleep for 4 hours.
These are a few links I found that are against polyphasic/reduced sleep:

I’m currently studying psychology and I could talk for days about how bad that advice is, but I figure if people try it out they’ll soon realize it’s not for them anyway.
I’m hoping this won’t make the new edition of the site when it’s released.
January 4, 2014 at 11:30 pm #43102Just sayin’. =P
January 5, 2014 at 3:17 am #43110So it’s like coffee? I mean: you don’t feel tired even though you are?
January 5, 2014 at 8:20 am #43127Kinda. It depends on what you’re doing each day and how naturally intelligent you are.
If your mind never contemplates much more than what you’re going to be eating at next meal time and you work as a manual laborer, you probably won’t notice it much.
If you’re studying Japanese, you will start to hate Anki to the point that you destroy your computer. And you’ll be more likely to follow through with the destroying part. It’ll start to be like you’re drunk once you do for a certain length of time.
That said, there is nothing wrong with doing some of the things suggested, as long as it’s in the short term.
It’s simply not sustainable.
There’s also correlative data that suggests that people who sleep too little tend to die sooner.
That said I usually consider those types of studies to not be worth the paper they are wrote on, but…
January 5, 2014 at 5:42 pm #43148Where did you find the time to get all those links when you’ve got Japanese to be studying? :P
I tried doing it a while ago but found I could never fall asleep quick enough for the whole napping thing to work properly, so I eventually gave up. The naps were supposed to be about 20 minutes but it would take me 15 minutes to actually doze off :P
January 5, 2014 at 10:25 pm #43155Very interesting post :P. I was considering looking into polyphasic sleep patterns, after seeing my (very disjointed) timetable for this year. I suppose that idea’s going in the bin. Thanks for the links :D.
On the broad topic of “finding time”, I would imagine the best method is to review what you realistically spend time doing every day. I suspect when I get back to serious studying, I’ll need to reduce my internet forum/article reading habits ;_;.
January 5, 2014 at 11:24 pm #43156It doesn’t take too long to find the links and read about them, maybe 30-60 minutes, I skimmed the scientific PDF’s.
Although I looked for polyphasic at first it mentioned reduced sleep. I’ve been sleeping for 5 hours a day for the last 4 months so I have some catching up to do.I’ve noticed I have a lot of the sleep-deprivation symptoms, though of course there could be other contributing factors.
Mainly though I just wanted to bring attention to how dangerous this piece of advise is so that it would be fixed, TextFugu is great and I especially love all the little bits of motivational help centered on this being for self-learners but if anyone followed through with this long-term then it would be really detrimental to how well they could study, which is the opposite of TextFugu’s intent.
Pantome, about finding time… generally even when I sleep less I I don’t do anything productive in the hours I ‘gained’, perhaps it would be better to go to bed early and wake up early so you have a continuous block of time to work and relax (I believe TextFugu mentions the Pomodoro technique somewhere, though I find I need longer breaks) while still having slept a good amount of time.
January 6, 2014 at 11:12 am #43170@Ricardo: You maybe ought to email Koichi with this suggestion. I know he’s currently in the process of overhauling most of the site but I have a feeling it’s not something he’s probably thought much into, plus he doesn’t visit the forum any more so he won’t see this thread unless you specifically show it to him.
@Pantome: “I’ll need to reduce my internet forum/article reading habits ;_;” – I try to reduce procrastination pretty much every day but it never (or rarely ever) works out :P I did, however, have great success when I removed Cracked and Kotaku from my Facebook feed – it was ridiculous the amount of time I spent reading articles on those sites; they’re all so long and pointless! It took a while to “get around” to actually doing the deed – I thought I was enjoying reading them all and didn’t really want to quit, if you get me – but when I did, I realised that I really didn’t lose anything from it. I can safely say I’m quite content not knowing “The 5 most mind-blowing facts about X you probably didn’t realise!”. So much information that took so long to read and probably about 90% I’ll never use again or could even tell you an hour after I read it. Of course, as soon as one distraction is gone, others gradually sneak their way in; I’m still unproductive as hell XD
January 7, 2014 at 12:28 am #43179Yeah I have a mate that always sends me links to kotaku, and I have over 300 unread e-mails in his folder. LOL.
