I do want to find a solution to a (for me) confusing state of mind. I'm a bit of a night-owl, always been one. The whole day I prolongue work that I want to do, my brain seems to sleep-in until after sunset. It does not matter if i get up at 3 am, 5 am, 8 am, noon, late evening, whatsoever - my brain does not wake up until late at night, where i can get very productive.
Now i wonder if there is a link between this phenomenon and some kind of special rays or waves, that would be emmitted at sunrise and later on sunset.
Mainstream research brought no conclusion, as their researchers are mainly focussed on during-the-day radiation (especially ultraviolet and infrared).
I found a study done in canada, which supports the "early bird" theories , which is linked to sunrise in a way.
Is there material out there, which shows special radiation or waves being emitted at sunrise / sunset? Please point me in the right direction :)
