+== Sleep Regularity
 To get maximum of your sleep time, it is crucial to sleep regularly – go to sleep at the same time every day and sleep for a fixed period of time.
 
 Sleep as Android tracks your sleep irregularity and shows you in <</sleep/charts#,Charts>> how irregular your sleep is.
 
 The irregularity shown is the https://en.wikipedia.org/wiki/Variance[variance] of your mid sleep hour.

+=== Sleep Regularity Index
+SRI is a metric calculated as the probability of an individual being in the same state (asleep or awake) at any two time points 24 hours apart, averaged over 7-days (range 0–100, with 100 being perfectly regular).
+This index can be used for monitoring your risk of health issues - read about the link  https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10153326/[between SRI and mortality], or the link https://www.nature.com/articles/s41598-017-03171-4[between SRI and academic performance].
+You can also read how https://academic.oup.com/sleep/article/44/10/zsab103/6232042[SRI compares to other sleep metrics].
