why does light keep us awake at night but it’s easy to nap in full sun during the afternoon?
In: Biology
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
