I've found in the discussion below a link to a non-scribd version and submitted that separately: http://news.ycombinator.com/item?id=1953834

a pdf inside a zip file inside cnet? that's just as bad, if not worse, than scribd.

Nah, if I want to download the pdf from scribd (to, for example, use a search function that actually works), I have to upload a document of my own or pay a subscription. Cnet is much less of a hassle.

I haven't read the whole guide yet but on page 8 it mentions polyphasic sleep (with annotation that majority of people who try it fail). Isn't polyphasic considered a popular hoax? As far as I remember, mentioned in the presentation dr Wozniak actually believes it simply doesn't work. Also, I've read a few blogs of people who tried it and failed (some of them appeared on HN) and don't recall a single person that succ…

All the accounts I have read seem to think it worked but go in the way of their lives to much. I doubt there are many out there which would be able to test this for a long period of time without anything at all getting in the way. From the sounds of it missing a single nap was extremely taxing.

While on the face of it it may qualify as a 'Geek's guide', there seems to be a fair amount of woo. "It is estimated that 70% of the population is lactose intolerant (dairy). 33% have yeast sensitivity. 15% have gluten sensitivity (wheat). And 35% have fructose or sugar sensitivity." Really? Any references to back that up? "Some raw-foodists say they need less sleep on a raw food diet compared to a cooked food diet."…

At least for the lactose intolerance, it completely depends on the population. It's fairly well known (and studied) that Asian populations have much much higher rates of lactose intolerance (thus the love of soy milk). The wiki article on lactose intolerance puts 75% of the global adult population at some degree of lactose intolerance.

Of course, if the majority of the people you know are white (European), then of course 70% looks fudged.

It's likely the same for many of the other stats, though I can't say.

The sleep bits are (probably - don't know very much about the topic) ok, but once it gets to diet, it goes right into la-la-land. It is riddled with misinformation and the belief that a "raw food diet" fixes all. A raw food diet might make you lose weight, and it might get you food poisoning, but that's about it. For more information, I recommend C0nc0rdance's youtube videos on raw food.

For other clearly wrong, or wrongly interpreted information: While 70% of the population is lactose intolerant, that doesn't mean you are. We do know that about 99% of the Chinese population is lactose intolerant (which proooobably skews the numbers a bit), yet, for example, only about 1% of Dutch people are lactose intolerant. Northern Europeans and other people from historically very dairy-rich cultures have a very high degree of lactose tolerance, and persistent lactase production (the enzyme that digests lactose and makes you lactose tolerant). Very interesting genetics topic :) Statistics will not say anything useful about whether you are likely to be lactose intolerant, but ethnicity will. Get tested if you are in doubt. It's a simple test. Just make sure you go to a qualified medical practitioner.

As for gluten insensitivity, this is called coeliac disease and is very serious. Thankfully, the highest estimate for prevalence is about 1%, not 15%. The anti-gluten brigade has been on it for years, but non-coeliac people can and should eat gluten. It's a good protein of high quality and makes your bread dough stick together. That's why it's hell trying to bake gluten-free bread or pizza dough.

Casein, a milk protein, is also not a bad protein. While there are many scare stories about casein (it being blamed for autism, cancer, et cetera), they don't hold up very well. Casein is a nice, slow-digesting protein with a very good quality, as any body builder who does the diet/protein thing will be able to tell you. Drink your milk if you can tolerate it, and eat more cheese :)

As for multiple sclerosis, we actually don't know what causes it other than that there likely is a genetic component, but that other factors also interfere. For the actual, REAL long term effects of coeliac disease, see here: http://celiacdisease.about.com/od/symptomsofceliacdisease/a/...

As for cortisol, your body regulates this itself. If you're stressed, stress down. But if your body doesn't regulate itself, you have a huge problem and need to see a doctor right away.

While "eat food, not too much, mostly plants" is very good advice, there's also another piece of advice that has been forgotten: "You are probably not sick, and your body can take care if it." Just eat a normal, healthy diet.

Man. That was long. Sorry about that, but I had to get some facts out.

I was polyphasic for about six months a number of years ago. My schedule was a fairly standard 6x20 minute naps (commonly called the Uberman schedule). After the initial (very, very difficult) adaptation period, I felt great nearly all of the time. I would get tired right before a nap, but by the end I didn't need an alarm to wake up after 20 minutes, and naps left me feeling completely refreshed and alert. I was in graduate school at the time, so my schedule was pretty flexible, and I had a mixture of cognitively demanding work (my research: a project in geophysical fluid dynamics) and less mentally demanding work (grading, family and home responsibilities). Again, after the adaptation period, I wasn't particularly cognitively impaired.

There is a lot of misinformation out on the web about polyphasic sleep, both by its proponents as well as its detractors. Some of the things that have been written (polyphasic sleepers only get REM, for example) are just false. One problem is that there isn't a very large body of peer reviewed literature on the subject; the canonical reference is a volume of conference proceedings from 1991 which can be hard to lay hands on. The fact that (a) adaptation takes a long time (on the order of weeks) and (b) the polyphasic schedule is incompatible with the way most people live their lives has made researching it difficult.

I'm currently involved in a polyphasic sleep experiment organized by the folks at Zeo. They asked for some volunteers to use their hardware to monitor our sleep as we either adapt to a polyphasic schedule or (for those already adapted) function on one. We're not following any kind of rigorous experimental protocol, so this isn't going to be publishable research, but it will at least provide us with some measured anecdotes.

In the U.S. at least, a normal, healthy diet is something of a contradiction. Michael Pollan wouldn't need to promote "eat food, not too much, mostly plants" if people were doing it already. I agree with you completely on your other points, but telling some people to eat a "normal" diet will be interpreted as, "eat out of fast food restaurants and freezer cases," because for many in the U.S., that is a normal diet.

Oh, a "normal" diet varies a lot depending where you are. Myself, I'm in Norway, and the diet here is fairly healthy if somewhat short on vegetables (especially during the winter). I'm sure most other "normal" diets in the world are quite ok, as well. Might need some added vegetables, depending on where you are (the Dutch probably don't need any extra), but mostly, people who are able to afford normal amounts of food will eat better than one would expect given the media hype. They might want to cut down on the amounts, and cut out the sugary drinks, but I think that's it.

You're being melodramatic.

Great to hear you have an opinion on the way I express my opinion. Do you also have an opinion on the matter itself?

The matter itself is a list of sleep hacks.

The worst thing about Scribd is the way it obligates people to ruin perfectly good HN threads with meta-commentary.

If you consider a normal, healthy diet as "eat out of fast food restaurants and freezer cases," then sleeping problems are probably not what you should focus on first.
