If you’ve already been diagnosed with some degree of hearing loss, the most effective thing you can do is reduce noise exposure, manage underlying health conditions, and get your hearing tested regularly so changes are caught early. Hearing loss from damage to the inner ear can’t be reversed, but the rate at which it worsens is largely influenced by factors you can control.
Know Your Noise Limits
Noise exposure is the single biggest controllable risk factor for worsening hearing loss. The National Institute for Occupational Safety and Health sets the hazard threshold at 85 decibels averaged over an eight-hour period. For every 3-decibel increase above that, the safe exposure time cuts in half. So at 88 decibels, you have roughly four hours before damage accumulates. At 91, just two hours.
The tricky part is knowing what 85 decibels actually sounds like in your daily life. City traffic hits about 85 decibels. A vacuum cleaner runs around 75. A power mower reaches 107, a chain saw at close range about 110, and a subway train at 200 feet sits around 95. Even a portable music player at half volume can reach 94 decibels. If you already have some hearing loss, these exposures do more cumulative harm than they would to someone starting with fully intact hearing.
Wear hearing protection any time you’re around sounds that force you to raise your voice to be heard. Foam earplugs, over-ear muffs, or custom-molded earplugs all work. For music or podcasts, noise-canceling headphones let you listen at lower volumes by blocking out background sound, which removes the temptation to crank things up.
Manage Cardiovascular Risk Factors
Your inner ear depends on a rich blood supply delivered through tiny, delicate vessels. When that blood flow is compromised, the structures responsible for hearing deteriorate faster. High blood pressure accelerates age-related hearing loss by damaging the tissue that maintains the chemical balance inside the inner ear. High cholesterol causes structural changes in the same area. Diabetes damages both the blood vessels and the nerve cells that transmit sound signals to the brain.
The CDC recommends that people with diabetes get annual hearing tests and stay on top of what it calls the “ABCs”: A1C (blood sugar control), blood pressure, cholesterol, and smoking cessation. That guidance applies broadly. Keeping blood pressure, blood sugar, and cholesterol in healthy ranges protects the blood supply your inner ear needs to function. If you’re on medication for any of these conditions, staying consistent with treatment is one of the most meaningful things you can do for your hearing.
Watch for Medication Effects
Certain common medications can damage hearing, especially with long-term use. The most frequently used ones with this potential are NSAIDs (ibuprofen, naproxen) and acetaminophen. In a study of older adults, 58% were taking NSAIDs and nearly 37% were using acetaminophen. Research from large, long-running studies found that people who used non-aspirin NSAIDs or acetaminophen two or more times per week had a higher risk of hearing loss compared to those who used them less often.
Other medication classes with known effects on hearing include loop diuretics (often prescribed for heart failure or high blood pressure), certain IV antibiotics, chemotherapy drugs, and quinine. If you’re already experiencing hearing loss and you regularly take any of these, it’s worth having a conversation with your prescriber. In many cases, alternatives exist, or the dosage or schedule can be adjusted. Don’t stop prescribed medications on your own, but do make sure every provider involved in your care knows about your hearing loss.
Quit Smoking
Smoking restricts blood flow throughout the body, including to the inner ear. Women who smoked 20 or more pack-years had a 30% higher risk of hearing loss compared to those who never smoked. Current smokers with the same history had a 21% increase. The damage is dose-dependent: the more you’ve smoked, the greater the risk. Quitting doesn’t erase past damage, but it stops the ongoing vascular harm that makes hearing loss progress faster.
Pay Attention to Nutrition
Several vitamins and minerals appear to have a protective effect on hearing, likely because they support blood flow and help neutralize the oxidative stress that damages inner ear cells. The evidence is strongest for magnesium, vitamins C and E, folate, and vitamin A.
In one study, people with the highest magnesium intake had hearing thresholds about 2.5 decibels better than those with the lowest intake. That may sound small, but over years of gradual decline, it adds up. Magnesium has also been studied specifically for protecting against noise-induced damage. People with the highest vitamin C intake showed thresholds roughly 2.4 decibels better than those with the lowest, and results were similar for vitamin E. A three-year trial of folic acid supplementation found that the group taking folate experienced about half the hearing decline in low frequencies compared to the placebo group. People with the highest vitamin A (retinol) levels had a 47% lower risk of significant hearing loss.
You don’t necessarily need supplements to get these nutrients. Magnesium is abundant in nuts, seeds, leafy greens, and whole grains. Vitamin C comes from citrus, peppers, and berries. Vitamin E is found in nuts, seeds, and vegetable oils. Folate is in leafy greens, beans, and fortified grains. Vitamin A comes from liver, dairy, eggs, and orange or yellow vegetables. A varied diet that consistently includes these foods gives your inner ear the raw materials it needs to resist further damage.
Protect Your Ear Canals
Earwax buildup can muffle your hearing and make existing loss feel worse than it is. But the way most people try to deal with it, using cotton swabs, hairpins, or other objects, can push wax deeper and damage the ear canal or eardrum. Never insert anything into your ear canal to dig out wax.
If you’re prone to buildup, softening agents like mineral oil, olive oil, or saline drops can help wax migrate out naturally. Over-the-counter drops containing carbamide peroxide also work, but should only be used as directed since they can irritate the delicate skin inside the ear. If blockages keep recurring, periodic professional cleanings once or twice a year can keep things clear without risking injury.
Recognize Signs of Progression
Hearing loss often worsens so gradually that you don’t notice until it’s significantly changed. Knowing what to watch for helps you catch shifts early, when intervention is most effective. Key signs that your hearing may be getting worse include:
- Speech sounds muffled even in quiet rooms, not just noisy ones
- Consonants become harder to catch, making words blur together
- You’re turning up the TV or phone volume higher than you used to
- Background noise feels more intrusive, making it harder to follow conversations in restaurants or group settings
- You’re asking people to repeat themselves more often than before
- New or worsening tinnitus (ringing, buzzing, or hissing in your ears)
- You start avoiding social situations because following conversation feels exhausting
Any sudden loss of hearing, especially in one ear, is a medical emergency that needs same-day attention. Gradual changes warrant a hearing test to establish a new baseline. If you work in noisy environments or already have diagnosed hearing loss, annual testing helps track whether your current protections are working or need to be adjusted.
Use Hearing Aids Early
If you’ve been prescribed hearing aids, wearing them consistently does more than help you hear better today. When hearing loss goes unaddressed, the brain gradually loses its ability to process the sounds it’s no longer receiving. This is sometimes called auditory deprivation, and it can make hearing loss feel like it’s worsening faster than the physical damage alone would cause. Hearing aids keep those neural pathways active. Many people put off using them for years, which makes the adjustment period harder and the perceived benefit smaller when they finally start. The earlier and more consistently you use them, the better your brain maintains its ability to interpret sound.
