Sleep banking is the concept of intentionally getting extra sleep in advance to offset anticipated sleep loss or deprivation

It involves "storing" sleep by sleeping more than usual—through longer sleep or naps—before travel, work deadlines, or events

The idea is to reduce the negative effects of sleep debt, such as fatigue, impaired focus, and mood changes

This can involve going to bed earlier or sleeping in later than usual to build up a sleep reserve

Studies show that extending sleep before sleep deprivation improves cognitive performance and alertness compared to normal sleep schedules

It's like filling a sleep "reservoir" to draw from later

However, it's not a perfect fix—chronic sleep loss still requires proper recovery, and banking too much sleep can disrupt your rhythm if overdone

Practically, you might sleep an extra hour or two per night for a week before a demanding period or take strategic naps

It's most effective when paired with good sleep hygiene, like consistent schedules and a restful environment
