Nintendo's Virtual Boy will agree. It will also lead to eye pain, plus side effects of headaches, nausea and seizures. lol
The theory is that red light naturally produces melatonin (and blue light supresses/delays it).
Actually UV-A light in the mid to late morning hits aromatic amino acids in the retina, which are building blocks of melatonin and dopamine. Melatonin is then released at night, presuming one gets a couple of hours of darkness before sleep. Blue light especially at night will suppress that release, and regenerative sleep will be evasive.
So essentially, unfiltered morning sunlight along with no blue light at night is the best strategy for improving sleep, and thus lowering all kinds of mortality risk factors. It's like we're designed to live by natural environments and cycles ; )
I love learning new things. Thank you! :)
I'm old enough to have played one of those.
The stories are completely true. The Virtual Boy really did cause you all sorts of headaches and eye pain if you played for more than about 20 minutes at a stretch.
