4 Ways Hearing Aids Can Improve Your Overall Health

Recent research funded by the National Institutes of Health and led by Frank Lin, M.D., of Johns Hopkins University studied nearly 1,000 people ages 70 to 84 who had significant hearing loss. The study participants were randomly assigned to two groups: One received hearing aids and were taught how to use them. The second group — the control — was enrolled in a health education program. 

The study found that those who wore hearing aids, not surprisingly, reported a substantial uptick in communication abilities, according to results published in 2023 in The Lancet.
