Editing Sleep tracking

Sleep plays an important role in restoration and memory processing and overall health<ref>https://en.wikipedia.org/wiki/Sleep</ref>. Normally, sleep is governed by a [[circadian rhythm]] of around 24 hours but a variety of disorders can  affect sleep, such as [[obstructive sleep apnea]] or [[insomnia]]. Furthermore, sleep can also be affected by influences such as [[stress]], alcohol consumption, [[Diet tracking tools|diet]] and other factors.

== Tracking sleep ==
A variety of methods for tracking sleep exist. The academic gold standard that is used in sleep laboratories is ''polysomnography'' (PSG), which measures brain activity through EEG (Electroencephalogram)‏‎, often complemented by [[ECG]], respiration, leg movement and other metrics <ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6579636/</ref>. 

While some consumer sleep tracking devices, such as the [[Muse S]] headband make use of EEG information, most wearable devices to date rely on data from [[heart rate]], [[accelerometer]], and increasingly [[temperature tracking|temperature]] sensors. A number of academic studies have compared the accuracy of consumer wearables to that of PSG, overall finding mixed results <ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6025478/</ref><ref>https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6579636/</ref><ref>https://academic.oup.com/sleep/article/44/5/zsaa291/6055610</ref>.

=== Sleep tracking devices/apps ===

* [[Muse S]], an [[EEG (Electroencephalogram)‏‎]] headband 
* [[Fitbit|Fitbit devices]], wrist-worn wearables that track sleep
* [[Oura Ring]], a finger-worn tracker which according to a study done by the company shows a 96% accuracy for sleep/wake prediction and 79% for detecting different sleep stages<ref>https://www.mdpi.com/1424-8220/21/13/4302/htm</ref>
* [https://www.risescience.com/ Rise] "pulls historical data from your phone to tell you your sleep need, sleep debt, and the best time for you to go to sleep."
* [[Withings Sleep]], a mat that can be put under the mattress to record sleep

== Sleep phases ==
Most wearables will divide sleep into 4 different sleep stages: 

* awake
* light sleep 
* deep sleep
* REM (rapid-eye movement) sleep
