Cell Phone Brain Buster

If you thought annoying rings tones just tested your patience, you might be surprised to learn that they can also impair mental function. Research published in the Journal of Environmental Psychology found that as little as 30 seconds of a cell phone's ringtone can decrease cognitive abilities by as much as 25%. The effect only lasts for a few minutes, but it's enough to affect the end result of a final exam or important workplace issue.

The Bigger Picture: Previous studies have determined that cell phone use while driving can be distracting to a potentially dangerous degree. This study goes beyond distraction to suggest that brain function is temporarily impaired. If these findings are any indication, it's probably a good idea to shut off your phone when you're busy lifting weights at the gym.
