why does light keep us awake at night but it’s easy to nap in full sun during the afternoon?
In: Biology
I don’t know exactly but I hate it.
Stimulation for me I suppose. An annoyance for my eyes that makes my brain focus on something instead of being calm and shutting down enough for REM sleep
Contrast.
When everything is illuminated, you don’t notice individual bright things, everything is bright.
When things are dark, light really stands out.
Your brain uses various signals to decide when to sleep or stay awake, one of them is blue light (which indicates day time).
However, this is one of many inputs. If you have a build up on adenosine in your brain then that too can make you sleepy even if its day time. You nap during the day because you are tired. You are tired because you stayed up on your phone all night and didnt sleep well enough
