Many people have heard that exercising keeps people healthy and fit but did you know that it is also good for your hearing? This is what researchers from the University of Florida are suggesting based on research performed on mice.
According to the research, it appeared that the structures needed to maintain the auditory system (hair cells and strial capillaries) were lost in inactive mice at a much higher rate, than mice that actively exercised. This resulted in a hearing loss of about 20% in inactive mice, whereas there was only a 5% hearing loss in mice that did exercise.
Likewise, hearing loss occurs in humans who are 70 years old or older when there is a loss of hair cells, strial capillaries and ganglion (found within cochlear system of the ear.) According to the research, it’s the hair cells that sense sound, while the strial capillaries feed oxygen to the auditory system, which is always on and always processing sound, it needs a large amount of oxygen.
The spiral ganglion is comprised of a group of nerve cells whose function is to send sound to the brain from the cochlea (the inner ear). This overall process is further stimulated when on-going exercise is taking place – thus decreasing age-related hearing loss.
