The Trouble With Tinnitus

Tinnitus, or chronic ringing in your ears, is experienced by a rising number of young people, likely due to ongoing and loud noise exposures. Those with tinnitus displayed signs of damage to their auditory nerves that may predict future hearing troubles.

Chronic TinnitusStory at-a-glance

  • More than one-quarter of young people may suffer from chronic tinnitus and incidence is on the rise, likely due to increased exposure to noise
  • Young people with tinnitus had significantly reduced tolerance for loud noise and tended to be more protective of their hearing, which may be signs of damage to the auditory nerves
  • Tinnitus may be a sign of permanent nerve damage that could predict future hearing impairment
By Dr. Mercola
Tinnitus, or chronic ringing in your ears, affects about 1 in 5 people. While it's typically not serious, it can significantly impact your quality of life, and it may get worse with age or be a symptom of an underlying condition, such as age-related hearing loss, ear injury or a circulatory system disorder.1
In the majority of cases, tinnitus is diagnosed after the age of 50 years, however, recent research has shown that tinnitus in youth is surprisingly common and on the rise, likely due to increased exposure to loud music and other environmental noise.2
Worse still, it may be a sign of permanent nerve damage that could predict future hearing impairment.

One-Quarter of Youth May Experience Tinnitus, Risk Hearing Loss Later in Life

In a study of 170 students between the ages of 11 and 17 years, researchers from McMaster University in Canada found "risky listening habits," including exposure to loud noise at parties or concerts, listening to music with ear buds and use of mobile phones excluding texting, were the norm.
More than half of the study participants reported experiencing tinnitus in the past, such as experiencing ringing in the ears for a day following a loud concert.
This is considered a warning sign; however, nearly 29 percent of the students were found to have already developed chronic tinnitus, as evidenced by a psychoacoustic examination conducted in a sound booth.3
Youth with and without tinnitus had a similar ability to hear, but those with tinnitus had significantly reduced tolerance for loud noise and tended to be more protective of their hearing.
Reduced sound level tolerance is a sign of damage to the auditory nerves because, when nerves used to process sound are damaged, it prompts brain cells to increase their sensitivity to noise, essentially making sounds seem louder than they are.

Prevention Is the Best Solution to Tinnitus

Auditory nerve injury that's associated with tinnitus and heightened sensitivity to loud noises cannot be detected by typical hearing tests, which is why it's sometimes called "hidden hearing loss." Further, such damage is permanent and tends to worsen over time, causing increasing hearing loss later in life.
Because there is no known cure, the best solution is prevention. Study author Larry Roberts, Ph.D., of McMaster University's Department of Psychology, Neuroscience and Behaviour has compared the emerging risks from loud noises to early warnings about smoking.
At this point, many people are unaware that listening to loud music via earbuds or at parties may be permanently damaging their hearing, particularly since they may still hear normally at this point in time.
If more people were aware of the risks, more would take steps to turn down the volume and give their ears a break. Roberts told Science Daily:4
"It's a growing problem and I think it's going to get worse … My personal view is that there is a major public health challenge coming down the road in terms of difficulties with hearing …
The levels of sound exposure that are quite commonplace in our environment, particularly among youth, appear to be sufficient to produce hidden cochlear injuries … The message is, 'Protect your ears.'"

Tinnitus Is Associated With Psychiatric Disorders and Stress

In adults, the majority of people with tinnitus (77 percent) may suffer from co-existing psychiatric disorders ranging from anxiety to personality disorders. Further, 62 percent of tinnitus patients may suffer from depressive disorders while 45 percent may have anxiety disorders.5
Further, there appears to be a close link between tinnitus and stress, such that stress may make tinnitus worse and vice versa. In one study, emotional exhaustion — or the feeling of being drained due to chronic stress — was a strong predictor of tinnitus severity.6
In addition, chronic stress may be as large a risk factor for developing tinnitus as exposure to occupational noise. Research has found that exposure to highly stressful situations and occupational noise each double the risk of tinnitus.7
Further, stress is especially influential in the transition from mild to severe tinnitus, with researchers concluding, "Stress management strategies should be included in hearing conservation programs, especially for individuals with mild tinnitus who report a high stress load."8
Also of note, many people with tinnitus first noticed the ringing in their ears during a stressful life event, such as divorce, being laid off, sickness in family members, accidents or surgery. As noted in the Journal of Neurology, Neurosurgery, and Psychiatry (JNNP):9
"These events can heighten the brain's arousal, and the tinnitus may be noted cortically [by the cerebral cortex]. This interaction between reduced auditory sensation and brain compensation might explain why some people are very bothered by their tinnitus and others just adjust to it."
The researchers have suggested that tinnitus is not simply a condition affecting the auditory system but rather is neuropsychiatric in nature, which would explain why it often occurs alongside cognitive and behavioral symptoms.

Other Tinnitus Associations to Be Aware Of: Sleep, Trauma, Headaches and More

Tinnitus is often described as a symptom, not a disease in itself, and it may result from a variety of conditions. Traumatic brain injury (TBI) is one common cause, with nearly 40 percent of military personnel with TBI also experiencing tinnitus.10
Tinnitus is also associated with pain disorders and headaches, including migraines, and often leads to sleep difficulties such as delayed sleep, mid-sleep awakenings and chronic fatigue. In addition, tinnitus is also associated with cognitive deficits, including slowed cognitive processing speed and problems with attention.11
There are different types of tinnitus as well, and the variety may give clues as to its origin. For instance, tinnitus may occur in one or both ears and be described as:12
  • Throbbing or pulsing, which may be due to vascular tumors near the ear
  • High-pitched and continuous (this is most common)
  • Clicking, which may be related to muscle spasms in the roof of your mouth, which cause the Eustachian tube in your ear to open and close; temporomandibular joint (TMJ) issues may also cause a clicking sound in your ear
  • Buzzing or humming
Abnormal bone growth in the middle ear, known as otosclerosis, may also cause tinnitus, as can damage to your vestibulocochlear nerve, which transmits sound from your ear to your brain. Such damage may occur from acoustic neuroma tumor or drug toxicity, for instance.

Additionally, certain medications, including certain cancer drugs, sedatives, and anti-inflammatories like ibuprophen and aspirin may also trigger tinnitus.  

If this condition is causing you serious emotional or physical distress, seek professional help. In many cases, however, natural interventions such as those described below may help.  

Effective Tinnitus Treatments

A slew of pharmaceuticals, including antidepressants, anxiety drugs, mood stabilizers and anticonvulsants, have been used to treat tinnitus.  A meta-analysis of a range of tinnitus management strategies revealed only antidepressants had a possible benefit, but even that study could not conclude that antidepressants were the answer.13
Considering their risks, and the fact that some antidepressants may cause ringing in the ears, non-drug options present the best course of action — and of these there are many.14
In many cases natural interventions, including the following, may help:
Cognitive behavioral therapy: which has been shown to improve quality of life in people with tinnitus.15 Even internet-based guided CBT has been shown to effectively manage tinnitus.16
Acupuncture: which was found to improve tinnitus severity and patients' quality of life.17
Nutritional interventions, herbal remedies and melatonin: specifically, zinc deficiency and vitamin B12 deficiency may be associated with tinnitus.18,19 Herbal remedies, including Japanese cornel, dogwood, bayberry, hawthorn leaf, ginkgo and black cohosh may also be useful.20
In animal studies, ginkgo extract led to significant improvement in tinnitus, including complete relief in some cases.21Melatonin also shows promise, and in one study melatonin supplementation led to a significant decrease in tinnitus intensity and improved sleep quality in patients with chronic tinnitus.22
Organic black coffee: research has shown that women who consumed higher amounts of caffeine (mostly in the form of coffee) were less likely to have tinnitus.23
Specifically, women who consumed less than 150 milligrams of caffeine a day (the amount in about 12 ounces of coffee) were 15 percent more likely to develop tinnitus than those who consumed 450 milligrams to 599 milligrams.24 The researchers weren't sure why caffeine may reduce tinnitus risk, although past research has shown it has a direct effect on the inner ear or may be involved through its role in stimulating your central nervous system.
Stress management: including exercise, relaxation exercises and the Emotional Freedom Techniques (EFT), is important for tinnitus treatment and prevention.

Simple Home Remedies May Provide Relief

If tinnitus is interfering with your quality of life, home remedies may help to relieve your symptoms (and if not, there's no harm done in trying). Organic Facts compiled several examples worth considering:25
Warm salt pillow: fill a fabric bag with warm salt. Lie down on the pillow and alternate each ear on the bag. Reheat the salt as necessary and repeat several times a day.
Foot baths: alternate your feet in hot and cold foot baths. This may dilate your blood vessels and stimulate blood flow toward your head, helping to relieve tinnitus symptoms.
Garlic oil: blend six cloves of fresh garlic with 1 cup of olive oil (the garlic should be finely minced in the process). Let the mixture steep for a week then strain out the garlic. Apply a few drops of the oil in each ear.
Music: soft soothing music, white noise, nature sounds or even humming to yourself may help relieve tinnitus.
Stimulate your little toe: use a toothpick to gently stimulate the edge of your little toe near the toenail. This should result in a tingling sensation near the top of your toe. Doing this once a day may relieve tinnitus symptoms.
Ear drumming: gently drum on each ear using your fingertips for two to three minutes twice a day to help relieve ringing.
Jawbone massage: massage the hollow and top areas of your jawbone behind your earlobes using coconut oil or sesame oil. You can also apply a hot compress to this neck area for relief.

How to Protect Your Ears From Loud Noise Exposures

While there are many causes of tinnitus, loud noise exposure is a primary culprit, especially among youth. It's far easier to prevent related damage to your ears than it is to treat it. The World Health Organization (WHO) recommends teens and young people take the following steps to protect their hearing and avoid hearing loss (although the advice applies to people of all ages):

Turn down the volume on personal audio devices
Try a decibel meter app for your smartphone, which will flash a warning if the volume is turned up to a potentially damaging level
Wear earplugs when you visit noisy venues (or when using loud equipment like lawnmowers or leaf blowers)
Use carefully fitted noise-cancelling earphones/headphones, which may allow you to listen comfortably at a lower volume
Limit the amount of time you spend engaged in noisy activities
Take regular listening breaks when using personal audio devices
Restrict the daily use of personal audio devices to less than one hour
