Any of you who read my blogs or irritated "status" updates know I don't sleep well. Ive always been one of those, "I'll sleep when I"m dead" people, but in the last year or two it's become ridiculous. Now maybe I know why.
Seems computers and smart phones (and tvs, but they aren't right next to our heads) emit a wavelength of light that is normally only found in daylight, and scientists suggest that this may be screwing with the circadian rhythms of some susceptible humans. They think that perhaps until technology can sort this out (and they're working on it as we speak) the best thing to do is not to play around with computers and phones right before - or in - bed.
I don't know about you, but if I can't sleep, the first thing I do after I finish reading my bedside book is haul out the computer and see what other night owls are up to. Or else I text my children, and if they're sleeping, I'll play some teensy game on the phone.
I may have to change that and just keep a bigger pile of books and magazines by the bed. Only I may have to change light bulbs, too - seems many of the fluorescent bulbs also emit this blue light.
