I have found that after I started practicing QiGong and exploring other 'Subtle Energy' products, I became more sensitive to telephones and cellular phones. At this point, I hate to talk on the cell phone more than a few minutes because of the heat and uncomfortable feelings it produces. As you get more in touch with your energetic self... you become more aware of things that will shift your body out of balance (Cell Phones, Power Lines, Computer Screens, etc) The best thing to do is Sword Fingers (Level II) on your ears to help restore balance to the area.
