Understanding Sleep Debt
Sleep debt, also called sleep deficit, is the running total of sleep you have lost by sleeping less than your body needs. Your body keeps a tally of that loss and tries to repay it through deeper, longer sleep.
Occasional short nights are easy to absorb, but chronic sleep debt has real consequences: slower thinking, low mood, a weaker immune system, a higher accident risk, and links to weight gain and heart disease.
The encouraging part is that sleep debt is recoverable. With a consistent schedule and a few nights of extra rest, you can steadily pay it down and restore a healthy sleep-wake balance.
