Many studies have been published that raise serious concerns about the effects of cell phone use on your health, but I still feel one of the best was published in Lancet in 2000. If you haven't already, please consider reading my review of it as well.

I used to discourage cell phone use entirely. Then, with the advent of headsets, my once stringent recommendations relaxed a little, as headsets seemed like a logical way to decrease radiation exposure from cell phones. However, I recently learned that emissions from your phone can still travel up the headset wire and into your head, potentially leading to even more exposure than you would get without one.

Of course, the best advice would be to reduce or even eliminate your cell phone use completely, but I realize that this is not a practical option for many of you.

The next best option would be to use the speaker phone on your handset if it has one. My experience, though, is that most do not have them, and even if they do it could be inconvenient to use in many settings. Without the use of a wire headset, moving your cell phone further away from your head will certainly decrease your exposure.

If you would like more information on this important issue, I urge you to watch the recently released independent documentary, PUBLIC EXPOSURE: DNA, Democracy and the "Wireless Revolution." This film provides a comprehensive, well-documented look at the science, economics, politics and potentially irreversible health effects of this 21st-century phenomenon.
