Tinnitus Is Connected to Sleep

5 hours ago

Tinnitus is a subjective sound like ringing, hissing, or buzzing, heard only by the affected individual.
Neuroscientists at the University of Oxford suggest a close link between sleep and tinnitus in the brain.
Tinnitus affects about 15% of the global population, with no known cause or cure.
Deep sleep (non-REM) may suppress brain activity linked to tinnitus, as seen in ferret studies.
Ferrets with severe tinnitus showed disrupted sleep and overly responsive brain activity to sound.
Deep sleep might temporarily mask tinnitus effects by engaging the same brain circuits.
Research indicates a potential vicious cycle between poor sleep and worsening tinnitus.
Stress is a strong factor in worsening tinnitus and may even trigger its onset.
Future studies aim to explore sleep as a therapeutic target for tinnitus treatment.
