The following may have a bearing on why you get drowsy Blossom.
I was asked by a naturopath, who wants a reader, to research the light emitted from them because blue light has a direct affect upon the melatonin levels in the body which affects circadian physiology, alertness, and cognitive performance levels.
Strangely, I found this
study which points to the need to design a computer screen with a spectral profile that can be individually programmed to add timed, essential light information to the circadian system in humans.
I say strange because I found the study half hour after I downloaded a
program for the Mac that modifies the computer screen with a spectral profile that can be individually programmed to add timed, essential light information to the circadian system in humans.
Anyway, I don't suppose anyone knows of a light emitting reader that can be programmed similarly, so night reading doesn't make you drowsy . . .heh!
