There was a thread not long ago about whether 'Catters ever sleep. Here at the Bedtime for Bonzo Sleep Disorder Lab over to the Neil Young Center, we have a new theory to advance for your comment.Seems a big part of my own not-sleeping was having bombarded my pineal gland with hours of bright but non-full-spectrum light, flickers as I page-hopped, 18 inches from my face with other light on in the room. This over-rode, sense, exhaustion, and even sleep-inducing chemicals. I finally reset the system with melatonin and a GOO-GOB of tears, also due for other reasons, physical and stress-levels. (The only other time melatonin helps me is during SAD season, so I had not tried it for this.) I told Hardiman it was like when we artificially light up the henhouse with more than 12 hours light, so the hens will lay eggs in winter-- it resets their diurnal rhythms. He said, I don't see any eggs. I said, well, they're all written ones, and tasty too, because the hens got a great diet. Bright yellow yolks, mmm. 'Course he didn't see them cuz I was taking all the online time!!!
Now I am sensitive to light and lighting effects, so I noticed these effects bigtime. I bet it's a factor for some of you others too.
I'll say more about my own lighting sensitivities cuz maybe that will give someone else a starting point to think about. If I get around a real strobe light I actually... well it's undiagnosed but it's a form of epilepsy similar to what are called phantasmagoria. You get that ometimes when you drive a dappled road and the sun dapples kinda make you... go somewhere... else.
So... anyone out there care to share?
PS, I have a light on now, and I limit my screen time!!
