Editing Sleep inertia (section)

==Symptoms==
* "Grogginess", as defined by a drowsy or disoriented state in which there is a dampening of [[Sensory cue|sensory acuity]] and mental processing.<ref name=":1">{{cite journal|last1=Hilditch|first1=Cassie|last2=McHill|first2=Andrew W|date=2019|title=Sleep inertia: current insights|journal=Nature and Science of Sleep|publisher=Dove Press|volume=11|pages=155–165|doi=10.2147/NSS.S188911|pmid=31692489|pmc=6710480|doi-access=free}}</ref>
* Impaired motor dexterity and decrease in cognitive ability. These gross impairments may be responsible for the associated increase in [[reaction time]] and drop in [[Attention|attentiveness]].<ref name=":1" />
* Deficits in [[spatial memory]]<ref name=":02">{{cite journal|last1=Hilditch|first1=Cassie J.|last2=Dorrian|first2=Jillian|last3=Banks|first3=Siobhan|date=2017-05-02|title=Time to wake up: reactive countermeasures to sleep inertia|journal=Industrial Health|volume=54|issue=6|pages=528–541|doi=10.2486/indhealth.2015-0236|issn=0019-8366|pmc=5136610|pmid=27193071}}</ref>
* Reports of heightened subjective [[fatigue (medical)|fatigue]]
* Reduced [[Vigilance (psychology)|vigilance]] and a desire to go back to sleep<ref>{{Cite journal |last=Trotti |first=Lynn Marie |date=October 2017 |title=Waking up is the hardest thing I do all day: Sleep inertia and sleep drunkenness |journal=Sleep Medicine Reviews |volume=35 |pages=76–84 |doi=10.1016/j.smrv.2016.08.005 |issn=1087-0792 |pmc=5337178 |pmid=27692973}}</ref>
These symptoms are expressed with the greatest intensity immediately after waking, and dissipate following a period of extended wakefulness. The duration of symptoms varies on a conditional basis, with primary expression during the first 15–60 minutes after waking and potentially extending for several hours.<ref name=":02" />  Tasks that require more complex cognitive operations will feature greater deficits as compared to a simple motor task; the [[Accuracy and precision|accuracy]] of sensory and motor functioning is more impaired by sleep inertia as compared to sheer speed.<ref name=":0" />  In order to measure the cognitive and motor deficiencies associated with sleep inertia, a battery of tests may be utilized, including: the [[psychomotor vigilance task]], [[Serial sevens|descending subtraction task]] (DST), [[Reaction time|auditory reaction time task]], and the [[Tapping rate|finger tapping task]].<ref name=":02" /><ref>{{cite web |url=https://www.inverse.com/article/50128-how-long-does-it-take-to-wake-up-the-brain |title=Brain Scans Reveal Why It Takes So Long to Wake Up in the Morning |date=2018-10-24 |access-date=2023-08-01 |website=[[Inverse (website)|Inverse]] |last=Betuel |first=Emma}}</ref>
