Intro: Sleep and circadian rhythm disturbances are frequent across diverse mental health disorders. Basic sleep hygiene recommendations advice against daytime sleep (napping) not to decrease the sleep pressure at nighttime. In depressive disorder, mood drops after sleep and daytime napping. Neuroimaging studies have found increased amygdala reactivity in response to sleep restriction together with increased impulsivity towards negative stimuli. Meta-analysis has raised concern of increased mortality with daytime napping, but results were not homogenous and reverse causality was suspected. Napping has some documented beneficial effects also: memory consolidation, preparation for subsequent learning, executive functioning enhancement, and boost in emotional stability. Knowledge of how napping might affect mood, affect and behavior in patients with mental disorders in the acute phase has not been systematically investigated. Previous work on napping has not considered the type and habituality of naps.
Metoder: Cross-sectional design. We will collect a sample of patients hospitalized due to a mental disorder irrespective of illness severity. Data will be collected by interview, questionnaires and staff observations in the medical record.
Resultater (forventede): The results will provide further knowledge on how daytime sleep may be associated with important aspects of psychiatric illness and subjective well-being.
Diskussion/Impact (forventet): The knowledge might serve as the basis for designing an intervention trial that more specifically tests hypotheses of daytime sleep as a potential therapeutic target.
