Hear this: running protects the auditory system
REGULAR exercise can help to prevent age-related hearing loss, a study has shown. Reporting in the Journal of Neuroscience, researchers from the University of Florida found that lazy laboratory mice lost structures that are important in the hearing system – such as hair cells and capillaries – at a much higher rate than their running counterparts.
Their results suggested that ageing sedentary mice experienced a 20% loss in hearing compared with a 5% hearing loss in mice who totted up about 7.6 miles running per day. It is thought that age-related inflammation damages the capillaries and cells in the hearing system and that exercising provides protection against it. “Exercise likely releases some growth factors yet to be discovered that maintain capillary density as compared to the control animals who were not exercising,” said Christiaan Leeuwenburgh, a co-author of the study and professor and vice-chair of research for the US’s National Institute on Aging. “Also, exercise may release other beneficial factors, but can also attenuate and blunt negative factors, such as inflammation.”
