Wearing earplugs helps protect the inner ears from loud sounds that can damage hearing. It should be safe to wear earplugs frequently—as long as they are clean and inserted properly, they aren’t causing earwax buildup or pain, and they aren’t used to avoid non-threatening everyday noise.

A 2025 analysis found hearing loss in 41% to 72% of people with diabetes, which was, on average, more than four times as often as in people without diabetes. People whose diabetes was less well controlled had greater hearing loss. Diabetes lasting 10 years or more doubled the risk.

The term ototoxicity describes inner ear damage from drugs that can cause tinnitus (ringing in the ears), and affect hearing and sometimes balance. Medications more likely to cause ototoxicity include aspirin; the antibiotics azithromycin and clarithromycin; certain chemotherapy drugs; loop diuretics such as furosemide (Lasix); and some biologics. These drugs can damage hearing by injuring hairlike projections in the inner ear. People taking ototoxic drugs should get their hearing tested before, during, and after using the drug.

A 2023 study suggests using hearing aids may reduce the risk of cognitive decline, especially in older adults with the highest risk of developing severe cognitive impairment.

For people who buy over-the-counter hearing aids, getting the devices is only a first step toward better hearing. It takes time to learn how to use, wear, and adjust the hearing aids, especially during the first two weeks. Tips to ease through this adjustment period include wearing devices at home for at least a few hours per day, and longer if possible; allowing soft sounds to be louder than normal at first; and learning to switch device settings for changes in environmental noise, such as going from a quiet street into a noisy restaurant.

A new medication called dupilumab (Dupixent) may help reduce nasal polyps in people with recurring polyps and chronic sinusitis.

A distorted sense of smell is quite common as people age. Called dysosmia, it can make people smell odors that are not there or be highly sensitive to certain smells. While it’s not bothersome for most, people should see their doctor if the condition becomes persistent.

Ears can feel clogged due to impacted earwax, swollen or blocked eustachian tubes, or hearing loss. If the sensation persists, a doctor should examine a person's ears and hearing.

A 2022 review of dozens of randomized controlled trials and observational studies found that people who used hearing aids or cochlear implants had a 19% lower risk of cognitive decline, compared with people who didn't use the devices.
