Medications are often necessary for the prevention of debilitating conditions, to fight infection and disease, or to help us maintain properly balanced body chemistry. Despite the remarkable benefits of modern pharmaceuticals, there is always the risk of undesired side effects. When dosage is properly controlled, side effects are usually minimal or at least manageable.

So far in this series, we’ve discussed how a diet rich in antioxidants can minimize or prevent toxic oxidative stress, and how oxidative stress leads to hearing loss through apoptosis. Now, we’ll concern ourselves with another way apoptosis and hearing damage may occur, and the devastating role noise exposure plays in this scenario.

A respirator isn’t the first thing that comes to mind when thinking about hearing protection.

In Part 1 of this series we discussed the benefits of antioxidants in general and the role they play in protecting hearing in particular. So, what is it, exactly, that antioxidants are preventing? Oxidation, as the name implies, of course.
