Electromagnetic Radiation from Your Laptop

Oh dear. Yet another thing to be wary of when it comes to laptop addiction.

For all that i love the portability that my 12 inch laptop affords me, I'm coming to accept that working at it full-time is *not* good for me. The postural problems that result from hunching forward over a laptop, and constantly looking down at a screen that's below eye level, are bad enough. But I've also started noticing something more insidious.

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 named Mark Levine, in Richmond Hill. While we were chatting after my (great) session, 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 MacBook 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 iCurve and 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!
