Accumulating a sleep debt:

Sleep loss is cumulative and builds a debt. Most people get 1 to 1.5 hours less sleep per night than they need. People whose sleep was restricted 4 to 5 hours per night for one week needed two full nights sleep to recover vigilance, performance and normal mood. How do you get out of sleep debt? Sleep!
