"grogginess" redirects to this page, and the first paragraph reads:

"Sleep inertia is a physiological state characterised by a decline in motor dexterity and a subjective feeling of grogginess..."

So, what exactly is "grogginess" and where can I find that info?--TiagoTiago (talk) 02:15, 19 September 2008 (UTC)


 * Someone has obviously made a decision to redirect, even though sleep inertia isn't the only possible cause of grogginess.
 * From Wiktionary, a very short definition: "Slowed or weakened, as by drink, sleepiness, etc."
 * Personally I'd define it as being temporarily unsteady, mainly mentally, possibly also physically. Confused and unable to think/function normally. Or to use another colloquialism: "in a fog."
 * Or, to steal a phrase from one of the links, "psychomotor vigilance deficit".
 * Does that help? --Hordaland (talk) 06:53, 19 September 2008 (UTC)

What's up with "Being awakened during this slow-wave sleep yields more sleep inertia than awakening from other stages of sleep. However, since one cannot predict accurately the stages of sleep that will occur within a nap, there is no physiological reason to try to limit the length of a nap. When one is sleep deprived, any sleep is good."? That's a non-trivial thing to say. Are there any studies supporting that? First, stages have an average length, so actually they could be predicted to some extent. Also, maybe having half a sleep stage is worse than not having it. Where is the evidence? 186.53.26.5 (talk) 08:49, 9 December 2015 (UTC)
