The relationships between sleep and measures of health and well-being in college students: a repeated measures approach.

The stability of subjective measures of sleep, health, and well-being, as well as the stability of the relationships between sleep and health and well-being were assessed over 3 months. Healthy college students with no consistent sleep complaints completed a 7-day sleep log and battery of surveys related to health and well-being at 3 separate times during the 3 months. Measures of health and well-being were more strongly related to the quality than to the quantity of sleep. Further analyses using the repeated measures results found that participants reported improved sleep and better health, but the affect balance, life satisfaction, and mood states were unchanged across the 3 testing periods. The relationships between the measures of sleep and measures of health and well-being remained constant across the experimental period. Even when working with a non-sleep-disturbed population, healthcare professionals should consider sleep quality as a consistent correlate of daily health and well-being.
