The vestibular system not only plays a role in maintaining body balance and orientation but may also affect sleep quality and duration. Sleep, in turn, may be related to the effective repair of vestibular nerves, and vestibular-related structures or functions can change in cases of sleep disorders. The interaction between the vestibular system and sleep has increasingly attracted attention. In recent years, scholars at home and abroad have conducted research on the mutual influence and related mechanisms between the vestibular system and sleep, achieving certain progress. This article reviews the recent research progress on the interaction and mechanisms between vestibular disorders and sleep disorders, aiming to provide better guidance for the diagnosis, treatment, and effectiveness evaluation when vestibular system diseases coexist with sleep disorders.
