| dc.description.abstract | Having enough sleep is relevant to avoid cognitive and emotional problems. Longitudinal studies are necessary to track how such problems might emerge in relation to sleep. However, the majority of such studies rely on behavioral and self-reported measures of sleep. This study aims to investigate how sleep varies in quality and quantity across time. We took an exploratory approach, using a multitude of measurements, investigating whether these variations in sleep are associated with any other variables such as subjective wellbeing. Therefore, during a continuous longitudinal study, we followed a single participant across one year on a weekly basis and acquired polysomnography (PSG) sleep recordings, self-reported questionnaires and behavioral tasks. The results show that our participant falls within the normal ranges of his normative group concerning the length of sleep stages but deviating in sleep efficiency and duration of sleep. We found that higher reaction times in the psychomotor vigilance task (PVT) predicted feeling more sick while higher sleep efficiency predicted lower feeling of sickness and more positive mood. Moreover, a higher number of minutes slept during the night predicted a lower level of tiredness. Furthermore, a frequency analysis revealed that certain ranges of frequencies (2-4 Hz and 12-14 Hz) fluctuated more across time compared to the other frequencies. Nevertheless, these fluctuations were not associated to behavioral changes. Overall, these results could aid in the development of personalized analysis, diagnostics and treatments. Through their high specificity, individualized interventions could thereby lead to an improvement of life quality. | en_US |
