Variability of sleep duration is related to subjective sleep quality and subjective well-being: an actigraphy study.

ABSTRACT: While there is a large body of evidence that poor subjective sleep quality is related to lower subjective well-being, studies on the relation of objective sleep measures and subjective well-being are fewer in number and less consistent in their findings.
