Study Says Cell Phones Cause Hearing Loss

I feel like Chris and I are tag-teaming on posts about the ill effects of cell phone use, but that's all we hear about these days. One study he mentioned yesterday suggests that cell phone use may slow your brain activity if you're a frequent mobile phone user. You might have good focus and better concentration, but your brain activity may be a little sluggish.

Today I found out via Switched that researchers at the Post Graduate Institute of Medical Education and Research in India found that people who talk on the phone for more than an hour a day could suffer from high-frequency hearing loss, particularly the ability to hear consonants such as s, f, t, and z. They also think that the longer you use a cell phone, the more damage you do to your right ear. An early warning sign of high-frequency hearing loss, according to the full report here, includes a warm sensation, fullness in the ears, or ringing indicative of damage to the inner ear. We've heard that loud music is dangerous to our ears many times before, maybe it's time to turn down the volume on our cell phones too.
