A Total Time in Bed Time between your bedtime (#1) and rise time (#7) Convert hours to minutes by multiplying by 60† (minutes) |
B Total Time Awake Add the numbers above in this column (minutes) |
C Total Sleep Time A minus B (minutes) |
D Sleep Efficiency C/A x 100% My sleep efficiency is % |
† For example, if you were in bed for 8 hours and 20 minutes, this is the same as 8 x 60 + 20 minutes = 500 minutes.
