Known medically as tinnitus, this often-distressing condition has seen significant advancements in understanding its causes. Westbury / Getty ImagesWhen an ambulance speeds by with a blaring siren, you instinctively cover your ears until the noise fades. Similarly, a cat's loud cries outside might prompt you to shut the window. However, for some, escaping intrusive sounds isn't as simple, as the noise originates internally. These sounds can manifest as ringing, buzzing, hissing, clicking, or crackling, and may vary in duration from intermittent to constant.
Tinnitus, the medical term for this condition, has been the focus of extensive research to uncover its origins. External vibrations travel through small bones behind the eardrum, reaching a fluid-filled chamber in the inner ear. Here, thousands of delicate hair cells detect the vibrations, converting them into electrical signals sent via the auditory nerve to the brain. The brain then interprets these signals as recognizable sounds, providing awareness of the external environment.
In some cases, hair cells can become damaged, causing them to send constant electrical signals to the auditory nerve even in the absence of external sounds. Essentially, these cells remain perpetually active, tricking the brain into perceiving continuous sound vibrations.
Hair-cell damage can result from various factors, including prolonged exposure to loud noises, earwax buildup, infections in the middle or inner ear, a ruptured eardrum, fluid retention, or ossification of the middle-ear bones. Additionally, conditions like allergies, blood pressure fluctuations, tumors, diabetes, thyroid issues, and head or neck injuries can contribute to this damage. Age-related deterioration of hair cells is another common cause of tinnitus.
While tinnitus is not life-threatening, it impacts nearly 50 million Americans, with 1 to 2 million experiencing severe symptoms that disrupt daily life. Fortunately, several home remedies can help alleviate the discomfort and make the condition more manageable.
Reduce noise exposure. Anyone who has been to a loud concert knows the ringing that persists afterward. However, consistently listening to music at high volumes on devices like iPods or Walkmans increases the risk of tinnitus. Prolonged exposure can even lead to temporary or permanent hearing loss. Each loud noise exposure further harms the delicate hair cells in the inner ear, diminishing the chances of recovery or the nervous system's ability to adapt and filter out the noise.
It's important to note that loud music isn't the only culprit. Many professions, such as factory and construction work, expose individuals to harmful noise levels. Hobbies like hunting or shooting can also damage hair cells. To protect your hearing, lower the volume on your devices and use proper hearing protection during noisy activities.
Monitor your blood pressure. Tinnitus is frequently linked to elevated blood pressure. Consider the ringing as an alert to undergo a thorough medical examination, as hypertension severe enough to cause tinnitus may also be harming other parts of your body. High blood pressure is a major contributor to heart disease, a condition far more serious than ear ringing and one that should never be overlooked.
Reduce sodium intake. While sodium isn't always an issue for those with tinnitus, individuals with inner-ear conditions like Meniere's disease or high blood pressure should minimize their salt consumption. Avoid obvious sources like table salt and scrutinize food labels for hidden sodium in snacks, processed meats, frozen meals, and canned soups. Opt for products labeled "sodium free," indicating less than five milligrams of sodium per serving.
Use aspirin cautiously. High doses of aspirin can lead to temporary tinnitus, often lasting a day after consumption. Regular use, such as for arthritis or chronic pain, may harm the ear's hair cells, though the risk varies with dosage (e.g., daily low-dose aspirin for heart health is less likely to cause damage).

Consider reducing aspirin intake to see if tinnitus symptoms improve (consult your doctor if aspirin is prescribed). Also, review labels of other over-the-counter medications, as many contain aspirin. If you rely on aspirin for chronic conditions, discuss alternative treatments with your healthcare provider.
Steer clear of stimulants. Substances like caffeine, found in coffee, tea, chocolate, and sodas, as well as tobacco and recreational drugs, overstimulate the ear's hair cells, causing unnecessary strain. Limit or eliminate these to reduce tinnitus triggers.
Stay active. If tinnitus stems from poor circulation, incorporating light exercise, like a daily brisk walk, might help reduce the ringing. Always consult your doctor before starting any new fitness routine.
Prioritize rest. Excessive fatigue can weaken your immune system, making you more susceptible to illnesses like colds or flu, which can inflame the inner ear and worsen tinnitus symptoms.
Stay calm. While tinnitus can be frustrating, remember it’s not a life-threatening condition. Obsessing over the noise can increase stress and anxiety, amplifying the perceived intensity. Consider stress-relief techniques to help soothe your mind and body.
Use sound masking. External sounds like soft music, white noise, or static from a radio can help distract from the ringing. These sounds are often more tolerable and can provide temporary relief from internal noise.
For severe tinnitus, a masking device resembling a hearing aid can generate soothing sounds to counteract the ringing. An audiologist can adjust the device to provide relief without disrupting normal hearing. However, these devices work for only a small number of people and are often used primarily at night to aid sleep.

In some cases, tinnitus may indicate a more serious underlying condition, though treatment might not eliminate the ringing. Elevated triglyceride levels in the blood can trigger tinnitus. If ringing is accompanied by symptoms like slurred speech, facial numbness, or vision changes, it could signal a stroke, requiring immediate emergency care. Tinnitus is also a key symptom of Meniere's disease, an inner-ear disorder affecting balance, and may indicate acoustic neuroma, a non-cancerous tumor affecting hearing and balance. If no clear cause for tinnitus is apparent, consult a healthcare professional to rule out serious conditions.
