A quickly example. Say your body needs 8 hours but you average out 6 hours, five nights a week:

2 hours short 5 weekdays 10-hour hebdomadally catch some Z’s debt

Multiply that across a month: 40 hours of additive debt that’s the combining weight of pull five all-nighters back-to-back.

1. Group A slept normally(8 9 hours)
2. Group B was restricted to 5 hours every night
