Answer:

a sleep debt.                        

Explanation:

Sleep debt is also known as a sleep deficit. It is the intensifying effect of not getting proper or enough sleep. A huge sleep debt can even lead to physical or mental fatigue. There are two types of sleep debt which include the results of total and partial sleep deprivation. According to a study, it takes almost four days to recover completely from the loss of one hour's sleep. Most adults sleep for only six hours each night.
