Turn up the volume: it’s good news for hearing aid-wearers.
Not sure whether hearing aids are worth getting? Well, scientists investigated their benefits – and the results are loud and clear. In fact, new research shows that hearing aids can reduce your risk of death by almost 25 per cent.
Despite there being 40 million adults in the USA who suffer from hearing loss, only 1 in 10 people who need hearing aids actually use them. In the UK, only 3 in 10 people who need the devices use them, though 11 million are affected by hearing loss.
Now, researchers from the University of South Carolina in the USA hope the findings of their study will encourage people to use hearing aids.
“These results are exciting because they suggest that hearing aids may play a protective role in people’s health and prevent early death,” said Dr Janet Choi, lead researcher of the study and otolaryngologist with Keck Medicine of USC.
The researchers believe that lower levels of depression and dementia are behind the longer lifespans. Improved hearing, according to Choi, goes hand in hand with improvements in mental health and cognition. These improvements promote overall health – and therefore longevity.
Published in journal The Lancet Healthy Longevity, the study is the largest to investigate this topic to date, examining 10,000 participants in total.
In the group of 10,000, the scientists identified 1,863 people as having hearing loss. Of these, only 237 people regularly wore hearing aids – meaning at least once a week for five hours. The majority, 1,483 people, were ‘never-users’ of hearing aids. The researchers described the remaining group as ‘non-regular users’, meaning they wore the devices less than once per month.
The researchers not only found that the mortality risk was 25 per cent higher in never-users compared to regular users. They also found that this was a steady rate: variables such as the degree of hearing loss, age, ethnicity, income, and others did not change the benefits of hearing aids.
Interestingly, the study did not find a difference between non-regular users and never-users. When it comes to hearing aids, this suggests you need to go all-in: occasional use of the devices likely does not boost your lifespan.
