A messed up sleep pattern due to late night studying. Especially among University studentswho study during the night and then get up early for lectures or exams just to fall asleep during the day when they get home. Adjusting after several weeks of late night studying back to a normal sleeping schedule is usually difficult and the student experiences a jet lag even though they haven't been traveling through time zones.

It is usually used when there is a ton of work to be done in little or not enough time frequently due to procrastination.

an invisible wall one hits when one has reached the point of study material saturation. All further attempts to study are futile and aimless browsing of the internet persists unabated.
After hitting the study wall, all I could do was look at rage comics on reddit until I woke up the next morning covered in piss.
