Computer use contributing to insomnia?

I remember long ago in the late 70's... when I didn't use a computer... I fell asleep every night.  As my computer use at work turned into use at work and at home through the mid-80's and all of the 90's, my insomnia began (around 1992-93) and continues to this day.  The artificial light that is emitted from a laptop or a desktop computer at work or home will eventually cause insomnia.  I'm certain of that.  The optic nerve was never meant to be stimulated on a constant basis.  I gave up TV in order to stop that artificial light stimulation and I erroneously replaced it with the computer light.  Now, I need to take something to "knock me out" in order to shut off an over-stimulated brain. 

Hi,

 

Yes, I'm sure that we should allow some time (an hour or two) after using the compuere before going to bed. Advice that I, myself, often fail to follow.

the night sky is no longer black as it once was, then there is lack of exercise as many fled to the burbs - but when you age your body no longer has all the natural hormones and stuff to put us to sleep.

 

look at a baby - it sleeps most of the time - we aren't babies anymore.
