Direct answer
Sleep debt is a practical way to describe accumulated sleep loss. It signals that recent sleep has been shorter than your need, but it is not a perfectly measurable bank balance and one long sleep may not erase every effect.
How to use it
- ✓Spot repeated short nights
- ✓Plan a steadier sleep opportunity
- ✓Discuss schedule constraints honestly
What it cannot prove
- !Individual sleep need varies
- !Wearable estimates are imperfect
- !Persistent sleepiness may need clinical evaluation
