Estimation of elapsed time after spontaneous wake-up from sleep in home setting

<p>Time estimation after wake-up from sleep has in earlier studies been shown to correlate with relative amount of slow-wave sleep. The aim of this study was to investigate if this effect could be found with subjects sleeping until spontaneous wake-up. Twenty-six women who slept alone at home, equipped with an actigraph and a questionnaire, participated in the study. The result showed that there was a positive correlation between time in bed, which was assumed to reflect relative amount of slow-wave sleep, and subjective time in relation to objective time. However, there also was a positive correlation between predicted wake-up time before going to sleep and subjective time in relation to objective time. This suggest that the former correlation might have been a result of pure intellectual guesses. Further studies, using more participants or different research designs, are needed to investigate or reject this eventual relationship.</p>
