Polyphasic Sleep

Sleep Efficiency and Sleep Health Score

By Nade

Averages [av] are not true averages but represent an ideal average based on 8h sleep recommendations. Everything is in minutes.

ST is sleep total

(sws<9) and (rem<9) are blocks of sws or rem that lasted less than 9 minutes, representing poor quality broken process of sleep.

Sleep Efficiency Score

= [ (SWS + REM) ST ] [ (SWSav + REMav) STav ] * 100

= [ (SWS + REM) ST ] [ (90 + 100) 450 ] * 100

= [ (SWS + REM) ST ] 0.42 * 100

Sleep Health Score

= [ SWS*3 + REM + (sws<9) + 1/2*(rem<9) – 5*(awakenings) ] [4.43 – (Age*0.0415)]
