Physical Activity Delays the Onset of Age-Related Hearing Loss
Age-related hearing loss affects almost two-thirds of U.S. adults over the age of 70. It’s a result of natural changes that happen in your inner ear, middle ear, and neural pathways as you age. The loss is gradual and can lead to communication problems, feelings of isolation, and decreased physical function. But results from a recent study in the Journal of Neuroscience suggest that regular exercise can delay age-related hearing loss.
The Study The researchers compared two groups of mice for 24 months. The experimental group regularly exercised by running on a wheel; the control group did not.
Mice in the exercise group had better hearing after 24 months than did the control group, and the physical findings supported this: For mice in the exercise group, key areas of the inner ear hadn’t broken down as much as the same …
