"I been noticing that when I work at my laptop for a while, my wrists and hands get hot from the heat coming off of it. The keyboard is directly over the CPU, after all. Worse than the heat, though, is the feeling of "vibration" that I've been feeling. It doesn't just feel like my hands are getting warm – it feels like they're being pumped full of some kind of energy. As I've become more attuned to it, it's become more and more uncomfortable to me.""Last week, I had an appointment with a craniosacral therapist …the topic of working at a laptop came up. He pulled up a little device he has that measures electromagnetic radiation. When he holds it over things, it registers the radiation coming off of them. As he held it over his … ..[laptop] keyboard, the little indicator shot off the chart. As he held it over his external keyboard, it barely registered anything at all."

"He showed me that you really don't have to get too far back from the CPU for the EMFs to drop significantly – but when you type at a laptop, you really are working direclty in an intense field of radiation. Which explains what I've been feeling… and makes me rather nervous."

"I've been meaning to invest in an…. external keyboard for a while now. No more excuses… I'm going to do it asap. It'll be much better for my back, and will hopefully also elimiate this creepy hot buzzy feeling in my hands that I've got as I type this!"
