I hear all the time that napping for 30 minutes mid day after 4 or 3 hours of work/studying has a ton of benefits and I hear that a lot.

But how the fuck is a nap a thing? Because for me it takes 30 minutes to fall asleep on a good day. and if i do fall asleep its more than an hour or two, and if I wake up in an hour i wake up more tired than before and just want to go back to a long deep sleep

So how the fuck are naps a thing? What constitutes a nap? how the fuck do some manage to take a thirty minute nap? Do you like need to fall asleep for it to count as a nap or is a nap just closing your eyes and relaxing?
