Improved sleep quality may ease tinnitus symptoms

A woman lies in bed with her eyes closed, appearing to be asleep, while a faint, glowing blue wave-like graphic or "sound ring" emanates from her ear. This visual representation illustrates the internal sound of tinnitus and its impact on rest and the brain during sleep.

New research suggests disrupted sleep is not just a consequence of tinnitus but may play a role in sustaining it

Neuroscientists at the University of Oxford have uncovered a close connection between sleep physiology and tinnitus, raising the possibility that improving deep sleep could help manage the condition.

For people who live with constant sounds such as ringing, hissing or buzzing, tinnitus can be distressing and in some cases disabling. New work from neuroscientists at Oxford suggests sleep and tinnitus are tightly linked in the brain. Understanding that relationship could open new therapeutic avenues.


A shared basis in brain activity

“What first made me and my colleagues curious were the remarkable parallels between tinnitus and sleep,” Linus Milinski of Oxford’s Sleep and Circadian Neuroscience Institute told ScienceAlert. Both rely on spontaneous brain activity, and exploring those similarities may “offer new ways to understand and eventually treat phantom percepts”.

The Oxford team proposed that the large, spontaneous waves of activity that characterise deep non-REM sleep could suppress the abnormal neural activity thought to generate tinnitus.


Evidence from animal studies

To test the idea, researchers used a ferret - because ferrets possess similar auditory systems to humans. Animals that developed stronger tinnitus after noise exposure also showed disrupted and reduced sleep.

“We could actually see these sleep problems appear at the same time as tinnitus after noise exposure,” Milinski said.

The same animals showed hyper-responsive neural activity to sound while awake. That hyperactivity was reduced during deep sleep, suggesting sleep may temporarily mask tinnitus by engaging overlapping brain circuits.

“Our findings indicate that deep sleep may indeed help mitigate tinnitus and could reveal natural brain mechanisms for modulating abnormal activity,” Milinski said.


Human data points in the same direction

Population studies now echo those findings. Analyses of US National Health and Nutrition Examination Survey data show that short or long sleep duration and disturbed sleep patterns are linked to higher tinnitus risk. Other analyses associate sleep disorders and difficulty sleeping with hearing problems and tinnitus.

Research also suggests that people whose tinnitus is influenced by sleep show altered REM and Stage 2 sleep patterns. These individuals also appear less able to suppress wake-state hyperactivity as they fall asleep.

A recent human study led by Xiaoyu Bao of South China University of Technology found that tinnitus-related hyperactivity was poorly suppressed during the transition to sleep but was reduced during deep sleep. The authors concluded that sleep represents a critical therapeutic target for interrupting the 24-hour cycle of tinnitus.


A vicious cycle of sleep and stress

“We often see a vicious cycle with tinnitus and sleep,” said Micaela Stonestreet, a Clinical Audiologist at Hearology®. “People with tinnitus can struggle to fall asleep, wake up during the night and can’t get back to sleep, or wake up early already distressed by the noise. Poor sleep then heightens the brain’s sensitivity to tinnitus the next day, reinforcing anxiety and awareness of the sound. That’s why a holistic approach to tinnitus management needs to consider sleep patterns and, where appropriate, involve sleep specialists to help break that cycle.”

The emerging picture is not a roadmap to a cure. It does, however, reframe tinnitus as a condition tied to fundamental brain dynamics and sleep physiology rather than solely damage to the ear. 

Oxford researchers are now exploring whether strengthening sleep-related mechanisms could prevent tinnitus from emerging or reduce its severity, through approaches ranging from behavioural sleep therapies to techniques that mimic deep-sleep brain states.
