Factors Linking Interoception and Sleep Across the Adult Lifespan.

ABSTRACT: Sleep patterns change with age, and interoception-a multifaceted concept referring to the perception of internal body sensations-may be one of the underlying mechanisms of these changes. The insula cortex, a key region for both interoception and sleep, might be a shared neural link. In this study, we examined the role of the insula in linking multiple interoceptive constructs with objectively measured sleep. We also investigated how interoception relates to sleep quality across the adult lifespan at different levels of anxiety. We measured interoceptive accuracy (the objective ability to detect internal signals), interoceptive sensibility (the self-perceived ability to detect these signals), insular volume (using structural MRI), objectively assessed sleep quality (via actigraphy), and tra
