This question has been answered by many, my answer is purely my personal opinion. Whether waking up at night is good or bad is entirely up to you
As I am a student, I don't sleep much at night since last two-three years. It did me no harm. And the rest of my study result is in the right line. I can't read much during the day, the environment is quiet at night so I read at night. I said the words in the context of studies, but it can be less about your profession.
The real issue is not waking up at night but whether you are sleeping properly. If you get the sleep you need, like me, you'll be sure to get your work done. And you keep your “OWL” identity.
