Sleep debt is the effect of not getting enough rest and sleep; a large debt causes mental, emotional, and physical fatigue. It is unclear why a lack of sleep causes irritability; however, theories are emerging that suggest if the body produces insufficient cortisol during deep sleep, it can have negative effects on the alertness and emotions of a person during the day.
