Sleep, a predictor of subjective well-being

Subjective well-being is not just a product of situational and dispositional factors, but is also based in part on underlying circadian rhythms. A pilot study was conducted in order to examine subjective well-being components which are affected by sleep. Sleep parameters, mood, and cognitive and alertness satisfaction were assessed by participants, through self-monitoring over a period of 14 consecutive days. We concluded that self-assessed resting level upon waking is a statistically significantly predictor of the mood which is affected by it to a greater extent than are cognitive and alertness skills, denoting the importance of sleep quality for daily well-being.
