COverall

QualityC

Frequent wake-ups are breaking up your rest; some nights notably worse than others.

DurationB

Sleep ranges from under 5 to over 7 hours; about 88% of time in bed is asleep.

TimingB

You fall asleep on time, but wake times vary over 2 hours; mostly fits your natural rhythm.

PerceptionA

You generally feel your sleep is adequate; some thoughts about sleep may add pressure.
