Simply thinking about an incessant buzzing, beeping, humming, or static noise in your head is annoying enough to make most of us cringe, but tinnitus can affect people's mental health and well-being in a very serious way. "A lot of people with bothersome or intrusive tinnitus are experiencing depression and or anxiety because of the ringing," Dr. Sherlock says. On top of that, "some people who are already depressed or anxious are more likely to react to having ringing in the ears than if they were not already depressed or anxious." An estimated 48-78% of people with severe tinnitus also have depression, anxiety, or other behavioural disorders, according to the American Tinnitus Association. In some cases, these associated conditions can lead to suicidal ideation , according to the Hearing Health Foundation.
