Nap section[edit]

I noticed that the section on naps is very short and is greatly lacking. The information is very limited and has not come from recent sources. Adding more information could greatly benefit readers. Alexa K Taylor (talk) 21:02, 29 September 2021 (UTC) Alexa Taylor[reply]

Sleep Disorders[edit]

I think this article would benefit some more information regarding sleep disorders especially since the lead contains more information about them then the actual sleep disorder section. I think the article could benefit with a parasomnia section including night terrors, enuresis, sleep talking, added to the somnambulism section. Saramouser (talk) 03:42, 20 January 2022 (UTC)[reply]

Brain waves in sleep - Edit request[edit]

"Alpha and beta waves are the only waves seen when a person is in an awake state. Gamma waves are seen when a person is highly focused on a task or using all their concentration."

These sentences are mutually contradictory. Please edit. RTBoyce (talk) 21:00, 21 April 2023 (UTC)[reply]

The current version says: "Beta waves take over alpha waves when a person is at attention, as they might be completing a task or concentrating on something. Beta waves consist of the highest of frequencies and the lowest of amplitude, and occur when a person is fully alert."
This is plain wrong. Beta waves do not have the highest frequency nor have
necessarily the lowest amplitudePlease remove the entire second sentence. Also, all these oscillations are brain area and task-dependent. Additional references are required.. (talk) 10:58, 22 January 2024 (UTC)[reply]

Semi-protected edit request on 13 June 2023[edit]

On the last line of the first paragraph in "Drugs and diet", there is a minor spelling mistake on the word "natural" highlighted bellow with brackets.

Change : "Interestingly, the endogenously produced drug gamma-hydroxybutyrate (GHB) is capable of producing high quality sleep that is indistinguishable from [natual] sleep architecture in humans." to "Interestingly, the endogenously produced drug gamma-hydroxybutyrate (GHB) is capable of producing high quality sleep that is indistinguishable from [natural] sleep architecture in humans."

 Done - Thanks. Next time, just WP:FIXIT yourself. Zefr (talk) 02:29, 13 June 2023 (UTC)[reply]

Semi-protected edit request on 11 September 2023[edit]

Remove the sentence: "Alpha and beta waves are the only waves seen when a person is in an awake state." as this is not true (see source). The attached source shows that other waves, such as gamma waves can be present when a person is in an awake state, and therefore alpha waves and beta waves are not the only waves.

Quote from source: "Nearly 40 years later another group [82] recorded gamma waves (35–40 Hz) from many different areas of awake humans, including the visual cortex, especially during selective attention."

No mention of the invention?[edit]

When searching via Google Search the query "when was sleeping invented,"'s article on the history of sleep appears with the highlighted segment "Around 450 BC." Where would this best be placed in the Sleep article?  Xan ✨ talk 21:17, 5 January 2024 (UTC)[reply]

Sleep was not "invented" or "discovered" so that kind of wording would be inappropriate. A history section might be good (like there is for blood) that just covers science history related to our understanding of sleep. D1551D3N7 (talk) 16:49, 16 February 2024 (UTC)[reply]


The introduction has not introduced all the subtopics that are in this article. There are many topics that emerge in the text without an introduction of them. The introduction should be revised and be able to convey all the information that is being presented in this article. Kyliek3 (talk) 04:08, 23 January 2024 (UTC)[reply]

Time devoted to sleep[edit]

Sleep "consumes fully a third of our lives—approximately 25 years in the average lifetime" (Kandel et al. 2021, p. 1080). Any reason this shouldn't be added to the article? Viriditas (talk) 22:10, 28 March 2024 (UTC)[reply]

Optimal nap time[edit]

  • The optimal nap duration is around 10–20 minutes, as researchers have proven that it takes at least 30 minutes to enter slow-wave sleep, the deepest period of sleep

Not sure this is even true. Many sources recommend 45 minutes, and that's what I do. I've rarely had sleep inertia, and when I do, it isn't due to napping, it's due to other issues. Viriditas (talk) 22:19, 28 March 2024 (UTC)[reply]
