Experts warn of the link between hearing loss and a higher risk of Alzheimer's, and how to prevent it

Research shows that hearing loss may raise the risk of dementia, making early detection and ear care essential

Hearing loss in seniors is more serious than many may realise. Studies show it may be linked to a higher risk of dementia, including Alzheimer's. Experts recommend regular hearing check-ups and taking care of your ears before the problem becomes serious.

Researchers are still looking into the connection between hearing loss and cognitive decline, but a meta-analysis published in Ageing Research Reviews found that every 10-decibel drop in hearing is associated with a 16% increase in the risk of dementia. With people living longer, this link is becoming increasingly important. A study in The Lancet Public Health projects that the number of people with dementia worldwide could rise from 57.4 million in 2019 to 152.8 million by 2050.

Limiting Noise Exposure

Limiting exposure to loud noise is one of the simplest ways to protect hearing. The World Health Organisation advised that sound levels under 80 decibels are unlikely to cause hearing damage, but prolonged exposure to levels above 85 decibels can be harmful. 

To put this in perspective, a normal conversation is around 60 decibels, a live concert or nightclub can exceed 100, headphones at high volume usually reach 95 to 105, an ambulance siren 110 to 120, a plane engine 130 to 140, and a gunshot or firework can top 150 decibels. Experts recommend using earplugs at concerts, sports events, or when using power tools. They also recommend limiting headphone use to one hour a day and keeping the volume below 60%.

The importance of ear care

Earwax can also cause temporary hearing loss, but this does not increase the risk of permanent damage or cognitive decline if treated promptly. Good ear hygiene is important, but experts say you should avoid washing your ears at home.

Cleaning at home should focus on the outer ear and you should never insert anything into the ear canal. Cotton buds, hairpins, keys, or even fingers can push wax further in and damage the eardrum.

Oils, alcohol, and home remedies are not recommended, and ear irrigation should never be attempted if there is pain. Specific drops or sprays can help with wax buildup, but frequent use should be avoided. If necessary, see a specialist for safe cleaning.
