Dreaming

According to Wilson & McNaughton (1994) Reactivation of hippocampal ensemble memories during sleep, Science, 265, 676-679, there is a correlation between neural activity recorded during awakened state and during the sleep afterwards (tested on rats). This suggests that the brain is processing the information gained during the day, and possibly reactivates the fresh memories to update the synaptic connection in neocortex, which requires iterative learning. Is this theory worth mentioning in the article? Niky cz (talk) 16:05, 11 August 2010 (UTC)

I've heard of that. Interesting stuff. I don't think there is room for it in Sleep. Maybe better in Dream, Sleep and learning or Sleep and Memory. --Hordaland (talk) 17:53, 11 August 2010 (UTC)

Nonpharmocological sleep disorder treatments: white noise

I added a 2002 article Evidence based complementary intervention for insomnia about white noise. The article doesn't have a ton of support so it would be nice to find more information. There's not many studies: Forquer & Johnson's Continuous White Noise to Reduce Sleep Latency and Night Wakings in College Students had only 4 people, and a couple reviews (The use of alternative medicine for the treatment of insomnia in the elderly and Nonpharmacologic techniques for promoting sleep) don't seem to mention much about it in their abstracts; I may try to get a hold of the full papers. I began using an air filter in my room to provide white noise and I've been waking up substantially more rested. II | (t - c) 06:39, 16 December 2010 (UTC)

Article presumes that sleep is necessary

I don't see any hard evidence proving that sleep is essential for human survival. But this article goes on to declare 'optimal amounts' and to discuss 'sleep debt'. Very presumptuous if you ask me. —Preceding unsigned comment added by 75.85.14.106 (talk) 20:49, 19 February 2011 (UTC)

There is plenty of evidence that sleep deprivation has adverse effects... just do a quick search in Pubmed you'll find lots of articles. Gould80 (talk) 08:07, 28 April 2011 (UTC)

Sleep graph

The graph (midnight to 6 am) doesn't show a normal night's sleep. For example are there only two N4 stages in a normal night's sleep? —Preceding unsigned comment added by 122.61.61.161 (talk) 06:04, 26 February 2011 (UTC)

Polar day/night

Is anyone familiar with any research about the effect of 24-hour sun or lack of sun (midnight sun/polar night) on sleep, or on other aspects of physiology? I didn't see any discussion of it in this article, and midnight sun and polar night have only brief, unreferenced sections about it. I'm especially interested if effects differ significantly between visitors to the polar regions, people who have lived there for several years, people who grew up there, and people who have a long ancestry from the region (Inuit, Sami, etc.).

REM atonia & sleep paralysis

Should there be any mention of the possible relationship between the atonia occurring in REM sleep and the phenomenon of sleep paralysis? Not being an expert on the subject, I am not certain if they are as related as my own experiences would indicate. 216.82.142.13 (talk) 20:35, 5 May 2011 (UTC)

Restructuring of Sleep Article Space

The sleep related article space neeeds a lot of restructuring. For example, the orphan page titled Somnology has good stuff but uses older termninology - see my comment on Talk:Somnology . Clearly Sleep is a great title for a "gateway" or intro article into the study of sleep and other areas related to it. As a gateway? (my term, is there an official WP one?) article it should reference a wide range of other WP pages. Perhaps, these kinds of articles should be titled XXXX_An Introduction where XXXX is the subject area. Codwiki (talk) 13:48, 6 June 2011 (UTC)

Well, Wikipedia articles arent given titles like that because they have to be things that people would search for or type in an address bar. Lots of people will type Sleep, not many will type Sleep: an Introduction. Also there's the fact that a lot of people will get to this article by following links from other articles, and those will be going to the title sleep, so it would have to remain as a redirect anyway. I don't mean to be discouraging though, I would like to hear your ideas for rewriting the content of Somnology. Or were you just directing that comment at the titles of the articles? —Soap— 02:09, 7 June 2011 (UTC)

Skin renewal?

I've heard that a 3 hour period, from 10pm-1am or 11pm-2am, is the time when skin cell renewal and regeneration is greatest during sleep. Is this true? Are there any medical studies showing evidence for it? Wsmss (talk) 14:08, 14 June 2011 (UTC)

Ontogenesis

Can more information be added to this section? How much sleep depravation causes the ill effects mentioned? Wsmss (talk) 14:08, 14 June 2011 (UTC)
