Hey, first time asking for an edit, so... Anyway, i think the section 2.1 Restoration should be revised... http://en.wikipedia.org/wiki/Sleep#Restoration it says that studies found that sleep deprivation is bad for healing. and yet, on the sleep deprivation page: http://en.wikipedia.org/wiki/Sleep_deprivation#Effects_on_the_healing_process It says the oposite. Both pages cite sources. But clearly they cant be both right. Can someone check into this? At least the text should change to inform that studies with both results have been done. Thanks. 189.148.120.35 (talk) 20:18, 6 May 2008 (UTC)AnonymSleeper

[edit] How much sleep do you need?
O.k. I saw the whole table for ages but what is the normal amount of sleep that generally anybody needs please tell me and where you found your information!!!!!!! Thank you!!!!!!! —Preceding unsigned comment added by Z heezey (talk • contribs) 02:43, 10 January 2008 (UTC)
- An adult in good health who sleeps regularly, timed according to her/his chronotype, needs enough sleep to not feel sleep deprived nor excessively sleepy during the day. It is possible that some need no more than 5 hours and some require 10 hours, but those are a very small proportion of the population. The average is about seven and one half hours for both women and men.
- For people living in a siesta culture and napping daily, the nap is included. People who nap only irregularly have a different quality to their naps. --Hordaland (talk) 09:05, 10 January 2008 (UTC)
- Z heezey has a point, we should have a source for those amounts. Puchiko (Talk-email) 15:44, 10 January 2008 (UTC)
- Several huge studies have been done using self-reported sleep time, not controlled. This has made news lately: long sleepers die younger. News makes it look like cause-and-effect, even when scientists haven't said that. Studies controlled by actigraphy, for example, are much smaller. --Hordaland (talk) 17:43, 10 January 2008 (UTC)
[edit] Tryptofan
Why does this page label tryptofan as a possible cause of drowsiness when the tryptofan page on wikipedia calls it basically an urban legend?(MGoers37 (talk) 01:08, 13 January 2008 (UTC))
- As I read tryptofan, it debunks tryptofan as a cause for drowsiness after eating lots of turkey (and other foods, which by itself can cause drowsiness). However, even in the case of tryptofan supplements it seems that the sources available are not entirely uncontroversial. Where next Columbus? (talk) 01:27, 13 January 2008 (UTC)
[edit] Archiving
This page is 47 KB KiB (7418 words) long. Because of possible technical issues, I think we should archive this page. Puchiko (Talk-email) 19:34, 27 January 2008 (UTC)
- Supported! Thanks for the warning; I just read through the whole page. Whew. --Hordaland (talk) 20:48, 27 January 2008 (UTC)
- Okay, I just read though Help:Archiving a talk page. I think the cut and paste procedure should be used. I'll go ahead and do it this afternoon, leaving the three most recent threads, in case someone wishes to discuss them further. Puchiko (Talk-email) 14:49, 28 January 2008 (UTC)
[edit] why sleep amount???
age nine is less slepp than 10-17 why? —Preceding unsigned comment added by 76.118.107.105 (talk) 22:00, 28 January 2008 (UTC)
- Our data is from [1] and [2]. You might want to try asking them. However, it's generally believed that teens need more sleep than pre-teens. Puchiko (Talk-email) 10:02, 29 January 2008 (UTC)
-
- I agree with Puchiko (again). On a related topic, one often reads that "we" are sleeping less than "we" did a few decades ago. That's been debunked by recent studies, at least with regard to self-reported hours of sleep. I don't know if there've been studies of kids older than nap age and pre-puberty (about 6-10), and of teens. I suspect that both groups (in the industrialized world) are sleeping appreciably less than they did a few decades ago. --Hordaland (talk) 15:47, 29 January 2008 (UTC)
I've shortened the table for amount of sleep by age. There are huge individual differences, also among children, so it seems unnecessary and almost misleading to provide so much detail. I looked at the sources provided and don't think I changed much except "7-8(+)" for all adults. One sees 7-9 or 8-9 often, but no one seriously means that all adults need 9 hours sleep. The vast majority (in western societies, at least) self-report 7.5 hours at the top of a fairly even bell-curve. --Hordaland (talk) 14:13, 19 February 2008 (UTC)
[edit] Adult photo
Why revert the photo of the adult sleeping, so that we have both child and adult, representing both aspects of biological sleep? 76.7.6.79 (talk) 20:59, 18 February 2008 (UTC)
[edit] Image:StreetSleepers3a.jpg
I have removed this image. Yes, it's funny. But there's already an image in that section, and I don't think this deepens the readers understanding of the subject (it's definitely not what I imagine under the term "sleep"). I'll admit that the article looked quite hilarious, but we're not Uncyclopedia. However, since the removal of the image could be viewed as controversial, I have decided to leave a note on the talk page. Puchiko (Talk-email) 21:00, 18 February 2008 (UTC)
- I agree. For start what are the verifiable sources that tell us he's asleep. Given the nature of the subject it is not unreasonable to believe that he could be unconscious rather than sleeping. Given the nature of the picture a reasonable reader could ask this question. Further I agree that this is not adding anything useful to the article. Gwernol 21:02, 18 February 2008 (UTC)

- I just don't think it's that representative of sleep. Lets try to pick a different image from commons:Category:Sleeping people, okay? The two I think are best for the article are Image:Israel 2 021 Sleeping Rucksack-Tourist.jpg and Image:Bezdomovci.jpg, as they clearly show that the people are sleeping (unlike the former picture), yet don't take place in conventional places for sleep (like the former picture). Puchiko (Talk-email) 21:10, 18 February 2008 (UTC)

- looks like they could be cuddling. The image I would like to use represented that sleep occurs anywhere, it is clear this person is sleeping. 76.7.6.79 (talk) 21:12, 18 February 2008 (UTC)

- You see, that's exactly the problem: in your opinion "he looks like he fell asleep drawing". He might be asleep. He might be drunk, drugged or dead. Its most likely he's asleep but its very plausible he's in another of those states. Any reader of this article could wonder about what the picture really shows. Unless you know for sure that this photo shows someone who is asleep, you can't claim for sure that he is asleep. Therefore you can't use this image in this article. Sorry, Gwernol 21:13, 18 February 2008 (UTC)

- May I have a certificate from a doctor that shows the child is not in a drug induced state. I don't understand how your argument then only applies to my proposed photo. 76.7.6.79 (talk) 21:18, 18 February 2008 (UTC)
- The author of the photo states it on the description page. 76.7.6.79 (talk) 21:22, 18 February 2008 (UTC)

- The editor who created that photo tells us the child is asleep and a reasonable person looking at the image would not doubt it. The photo you are proposing adding has neither of these attributes to recommend it. Gwernol 21:22, 18 February 2008 (UTC)

- I just don't think it's representative of sleeping people, most people are lying down.
You have a point, we can't prove the girl is sleeping wither.
I've thought about this, and I guess I don't really mind if the image 76.7.6.79 added stays in the article, but I'd prefer a different one. When I saw the edit, I burst out laughing, which isn't really the purpose of this article. It's 10:20 PM over here, let's finish this discussion quickly so I can sleep.
P.S. I hate edit conflicts, this is like the fourth one in this discussion. Puchiko (Talk-email) 21:23, 18 February 2008 (UTC)

[edit] The trivia section
The Rhett Lamb portion can be verified at the following site or by simply Googleing his name. It's legit I just don't know how to add citations. Anyone who does know how is welcome to use the google to confirm and add the citation. But again it is legit. http://www.baynews9.com/content/36/2008/5/8/346720.html?title=Rare%20condition%20doesn't%20let%20St.%20Petersburg%20kid%20sleep —Preceding unsigned comment added by 24.97.195.241 (talk) 00:17, 22 May 2008 (UTC)
OK, it's called Longest period without sleep, not "trivia", and starts "Depending on how sleep is defined, there are several people who can claim the record for having gone the longest without sleep:"
- Thai Ngoc ... claims to have been awake for 33 years ...
- Randy Gardner holds the Guinness World Record for intentionally having gone the longest without sleep. ...
- ... Tony Wright beat the Guinness World Record by staying awake for 11 days and nights. ...
- There have been various, though largely unsubstantiated, claims by methamphetamine users that with the aid of methamphetamine they have gone without sleep for periods of up to two weeks. Users reportedly experience severe auditory and visual hallucinations that descend rapidly into methamphetamine psychosis[citation needed].
Tho I don't much care for trivia sections, nos. 1, 2 and 3 can stay there. No. 4 is just very vague rumor. I would guess that there are scientific reports on meth's effects on sleep, and that that info could easily be inserted elsewhere on the page, if desirable. I want to delete point 4 above. Objections? --Hordaland (talk) 14:33, 19 February 2008 (UTC)
- No objections, so I'm deleting point 4, quoted in full above. --Hordaland (talk) 07:37, 22 February 2008 (UTC)
[edit] Memory processing
- Turner et al. allowed 18 women and 22 men to sleep only 26 minutes per night over a 4-day period. [...] This demonstrates that there is clearly a connection between sleep and memory.
This does not show ANYTHING. 18 women and 22 men, while there are 6,000,000,000 people or so living on Earth? In addition, most psychologists perform their experiments asking for people to participate. The people who participate are generally university students between ages of 18 and, say, 24 who attend that very same university. So, if this shows ANYTHING AT ALL, it might be about university students between ages 18 and 24 at THAT PARTICULAR UNIVERSITY IN THAT PARTICULAR COUNTRY. It says NOTHING about people not in that group. And the amount of people they tested is too small anyway to be statistically meaningful (psychologists like to use the word "significant" instead). Their research cannot be used to make ANY determinations stated like "This clearly demonstrates". 40 people? 40 people out of 6,000,000,000? 40 people who were probably between ages 18 and 24? 40 people who probably were university students? 40 people who were probably all living in the same area and probably attending the same university? How does that "clearly" show ANYTHING about people of all ages world-wide? This is a ludricous statement. 67.8.56.20 (talk) 02:14, 20 February 2008 (UTC)

- That was a nice rant. The abstract of the study you're criticizing is here; I don't know why there are so many linkless refs to the article.
- I agree that the whole Memory section needs re-doing. It's full of details about small studies. When one or more competent people do a review article about such studies and results, they may become (collectively) meaningful. This is research in a fast-moving field. For example, the chronotypes of these 40 young, healthy people weren't taken into account, and very recent research suggests that morning people and evening people react differently to sleep deprivation. Wikipedia editors need be very careful using small, recent studies, though I don't agree that results of small studies are totally meaningless.
- I hope to be able to tackle that section when I've read up a good bit more. If you feel yourself competent, please do work on it. --Hordaland (talk) 16:01, 20 February 2008 (UTC)
- I hold a Master's degree in Psychology. While studying Psychology, I found that most people in that field design experiments and then ask people to take those. The people participating usually get some monetary reward. But most, if not all, of the people participating are just students at that university. So it says nothing about non-students at that university. I already held a Master's degree in Computing/Computer Science when I started studying Psychology. As a result of my previous education, I learnt a lot more about statistics than most Psychology students or even professors ever will. After I got my Master's in Psychology, I was a professor for some years. I learnt then that lots of people active in the field of Psychology go out of their depth to make the results of their experiments "statistically significant". They use programs like SPSS and twiddle with the settings until they get a "statistically significant" result. And then they have something they can publish and get credit for. While there are some people in the field of Psychology that I truly have respect for, most of them (in my opinion, of course) just use some experiments performed on local students at that particular university and find some way to make a program like SPSS make those findings seem statistically significant. To me, personally, my Master's degree in Psychology is just a joke. Sure, it's a degree, but, no, it means nothing compared to the Master's I hold in Computer/Computing Science. And, unfortunately, I very quickly learnt that most people holding a Ph.D. in Psychology and are professors at universities have no clue. I got into fights many times. Because of my "real" scientific background. Social Sciences, unfortunately, in most cases, is just a joke. From the moment I enrolled as a Psychology student until I received my Master's degree in it was a little over 2 years. I think that proves a lot more than all the experiments I myself participated in as a student and all the experiments I conducted as a "psychology professor". But, to answer your last line, no, I don't want to work on it. I'm probably competent, but I have moved away from the field. I only started my rant because it reminded me of what I went through. 67.8.56.20 (talk) 17:30, 20 February 2008 (UTC)
- Well and good. I don't want to argue, just to point out that there are many specialties other than psychology studying sleep. They get their act together occasionally, as at the conference in the first reference to this article, and the progress is exciting. Any real expert readily admits that there's much more left to learn than what we already know. --Hordaland (talk) 17:57, 20 February 2008 (UTC)

[edit] Human/non-human sleep
This article should really be separated into sleep and sleep in humans. Sleep isn't exclusive to humans but many sections of this article act that way. ...Shot not doing it. Leopold Stotch (talk) 05:13, 22 February 2008 (UTC)
- (I don't understand your last sentence.)
- This is on my list of projects to get at! We have a newish article, Sleep (non-human), and the animal section here should summarize and point to that article. --Hordaland (talk) 07:34, 22 February 2008 (UTC)
[edit] Children and adolescents
Anonymous contributor writes: "I changed the amounts of sleep for adolesents and children from 5-12 years of age."
There are 2 sources given for the info which was in the table before that edit. The first one says 5-12 yrs, 9-11 hrs and adolescents 8.5-9.5 hrs. The other one says
- Ages 6 to 9: about 10 hours of sleep
- Ages 9 to 12: about 9 hours of sleep
- Teenagers: About 9 hours of sleep per night.
It is not at all OK to change info which is sourced. If Anonymous has sources which say something else, a new paragraph about the disagreement & new refs are in order. Reverting. --Hordaland (talk) 23:09, 27 February 2008 (UTC)
[edit] Is it possible to go without any sleep?
If you go without sleep for a long enough period of time will your body adapt to not needing to sleep at all? Just wondering. :0 —Preceding unsigned comment added by 68.151.97.103 (talk) 18:44, 28 February 2008 (UTC)
- Hi. I moved your comment to the bottom of the page, it's a custom to put new threads to the bottom. You should also sign your posts by typing four tildes (~~~~) or pressing the signature button (
). Furthermore, this talk page is to discuss improvements to the article, it really shouldn't serve as a general forum about the topic. See WP:Talk page guidelines for more information.
Concerning your question, the answer is no. This article says In humans, other mammals, and a substantial majority of other animals which have been studied — such as fish, birds, ants, and fruit-flies — regular sleep is necessary for survival. While sleep is essential for survival, its purposes are only partly clear and are the subject of intense research. The article Sleep deprivation provides excellent further material about the effects of lack of sleep in general, but I'll just quote the most important part In rats, prolonged, complete sleep deprivation increases both food intake and energy expenditure, leading to weight loss and, ultimately, death.
I mean there is this guy who claims he's been awake for thirty years, but I don't believe him. --Puchiko (Talk-email) 19:19, 28 February 2008 (UTC)
Hello all! Long time listener, first time poster (or something), so, go easy. I got a bee in my bonnet about "rats die if they don't sleep" not having a citation and came up with the following (which probably has better wording, too - their wording, not mine): "Sleep deprivation of over 7 days with the disk-over-water system results in the development of ulcerative skin lesions, hyperphagia, loss of body mass, hypothermia, and eventually septicemia and death in rats" http://books.nap.edu/openbook.php?record_id=10732&page=121
I have made other, generally minor, edits before without discussing them. I think that this one warrants some discussion, and wanted to float it and see if there were thoughts. Thoughts? Sredmore (talk) 03:52, 1 June 2008 (UTC)
- Your exact quote "rats die if they don't sleep" doesn't appear in the article, so I suppose you mean "They started dying after 5 days." That's a typical statement which should have a reference. I'm pretty sure that I've seen a ref for that somewhere, and also one for something like "they were all dead within 14 days" -- I don't know where.
- But you've found an interesting link which covers it. I'd rather see the whole quote in the ref itself, and a very short version in the article. Go for it. --Hordaland (talk) 05:24, 1 June 2008 (UTC)
- No discussion required. Just do it. --David from Downunder (talk) 09:25, 1 June 2008 (UTC)
