This always breaks my brain. From what I have read about sleep and the effects on caffeine on sleep, coffee nap seems to work in a very different way than just having coffee when you feel sleepy.

Some research suggests, it boosts your energy level as caffeine doesn't have to compete with adenosine (which make us sleepy)as by sleeping adenosine levels drop. But I always wondered how the boost works, when infact you could just have a nap and then drink coffee and the same thing should happen.

Anyway, I need to read more about this someday.
