Daily activity helps preserve hearing in older adults

Scientists from the University of South Carolina have found that among older adults, a higher level of physical activity is associated with a lower risk of hearing loss. A team of specialists from the Department of Communication Sciences and Disorders, together with colleagues from the Arnold School, analyzed data from 150 adults aged 50 to 80 from the Aging Brain Cohort project. The participants had previously undergone a comprehensive assessment, and then experts collected information about their cognitive abilities, hearing, blood pressure, daily physical activity, and other aspects of health and lifestyle.

According to study leader Jean Nils‑Strunjas, these results suggest that systolic blood pressure is probably not a key predictor of hearing loss or cognitive decline in healthy older adults. At the same time, direct support for physical activity may be a more effective strategy for preserving hearing and cognitive health than relying solely on blood pressure control.

It is important to note that the sample mainly consisted of women, so the results may not fully reflect the situation for other population groups. Furthermore, this concerns an identified association, not a proven mechanism. The study does not explain exactly how activity protects hearing, but it convincingly demonstrates such an association.

Hearing loss is widespread among older people, and today hearing aids are often the primary solution. However, experts are increasingly focusing on prevention: preserving hearing before it begins to decline can be much more beneficial. The data suggest that large‑scale programs aimed at maintaining physical functionality in older adults can significantly improve long‑term outcomes for this growing population group.

The authors emphasize that any issues related to blood pressure should be discussed with a healthcare provider. However, their work provides an additional argument in favor of the idea that regular, moderate physical activity can be a potential tool for protecting hearing as people age.
