Sleep banking is a concept that involves storing up or banking sleep hours when one has the opportunity, with the idea that this reserve can be used when one may be short on sleep. It is based on the belief that getting extra sleep when possible can help reduce the adverse effects of sleep loss. While the idea of sleep banking is intriguing, there is ongoing debate about its effectiveness. Some studies suggest that it can help improve performance and alertness during periods of sleep deprivation, but others argue that it is more about repaying sleep debt rather than truly banking sleep.

| Definition | "Sleep banking" is a concept that involves storing up, or "banking," sleep hours when one has the opportunity, with the idea that one can use this reserve when they may be short on sleep. |
| Effectiveness | Early research suggests that sleep banking might be effective in helping people get better rest. Some studies say that when people get a few extra hours of sleep leading up to a period of reduced sleep, they perform better than those who did not bank those extra hours. |
| Sleep Debt | Sleep debt refers to the difference between the amount of sleep you should be getting and the amount you actually get. It's like a negative balance in your "sleep bank." |
| Limitations | Sleep banking is less effective for those who already have an existing sleep debt. |
| Scientific Controversy | There are two schools of thought on sleep banking. Some believe that if you get enough sleep and build up to an event, you can afford to miss one night's sleep. Others argue that you cannot bank sleep, and that extra sleep is ineffective when you've already had plenty. |

Sleep banking may help counterbalance sleep deprivation
Sleep banking is a concept that revolves around the idea of storing up or "banking" sleep hours when one has the opportunity, similar to storing money in a bank account. The notion suggests that by getting extra sleep before a period of anticipated sleep deprivation, one can counterbalance the negative effects of sleep loss.
The idea of sleep banking stems from the understanding that sleep is crucial for optimal health and performance. In today's fast-paced society, sleep deprivation is a prevalent issue, with many individuals consistently failing to get the recommended amount of sleep. Sleep banking offers a potential solution to this problem by encouraging individuals to proactively manage their sleep schedule and make up for lost sleep in advance.
Neurobiologist Allison Brager, author of "Meathead: Unraveling the Athletic Brain," compares sleep to a bank account. She explains that just as depositing more money in a bank account allows for larger withdrawals, getting extra sleep ahead of time can help individuals withstand periods of sleep deprivation and maintain their performance and alertness. This concept is supported by numerous studies, including a 2015 study published in the journal Sleep, which found that participants who slept longer than usual for six nights and then had their sleep restricted exhibited improved sustained attention and alertness.
However, it is important to note that the effectiveness of sleep banking is still a subject of debate. Some experts argue that the concept of sleep banking may not be as straightforward as it seems. Dr. Rafael Pelayo, a clinical professor of sleep medicine, suggests that individuals who practice sleep banking are simply repaying their sleep debt rather than actually banking sleep. He emphasizes that the benefits of sleep banking may be more closely tied to reducing existing sleep debt rather than storing sleep for future use.
Additionally, the two-process model, a framework used to understand sleep-wake dynamics, implies the existence of a stable set-point for sleep. According to this model, deviations from a certain level of sleep (either a deficit or excess) would trigger a proportional adjustment in the subsequent sleep amount and intensity until equilibrium is reestablished. This notion seems to contradict the idea of sleep banking, as it implies that the set point is altered, which is not supported by the existing data.
In conclusion, while sleep banking may provide some benefits in counterbalancing sleep deprivation, it is important to approach the concept with a nuanced understanding. Further research and studies are needed to fully comprehend the effectiveness and limitations of sleep banking as a strategy for managing sleep deprivation.

Sleep debt and sleep banking
Sleep banking is a strategy that involves getting extra sleep in anticipation of a period of sleep deprivation. It is based on the idea that sleep debt can be repaid or offset by getting more sleep beforehand. While it is not truly "banking" sleep for future use, sleep banking can help to counterbalance sleep deprivation and improve performance and alertness during the anticipated sleep-deprived period. This strategy can be particularly useful when individuals know they will be experiencing less sleep due to travel, a big project, exams, or welcoming a newborn.
To implement sleep banking, individuals can strive for an extra hour or 90 minutes of sleep each night in the week leading up to the anticipated sleep-deprived period. Napping and sleeping in on weekends can also help to make up for missed sleep, but it may take several days to recover from the negative effects of sleep loss. It is important to prioritize sleep and practice good sleep hygiene to avoid accumulating sleep debt and its associated health consequences.
While the concept of sleep banking has gained attention, some experts argue that it is not truly possible to bank sleep. Dr. Rafael Pelayo, a clinical professor of sleep medicine, states that individuals who feel better after sleep banking are simply repaying their sleep debt and returning to normal levels of alertness and attention. He suggests that if sleep could be truly banked, individuals could stay up for days at a time without needing to sleep.
Overall, the concepts of sleep debt and sleep banking highlight the importance of recognizing the impact of sleep deprivation and striving for healthy sleep habits to maintain optimal health and performance.

Sleep extension and its impact on alertness and performance
Sleep extension refers to the voluntary lengthening of nighttime sleep duration without greater-than-normal homeostatic sleep pressure. In other words, it is when individuals sleep more than they usually do. Sleep extension has been shown to have a positive impact on alertness and performance.
Multiple studies have reported that extended sleep reduces sleep propensity and improves performance and mood. A study by Rupp et al. found that sleep extension did not affect subjective sleepiness. However, the intrusions of microsleeps during wakefulness were less frequent in subjects from the extended sleep group, indicating improved alertness.
A study on Japanese national wheelchair basketball teams found a correlation between sleep and psychological mood states in female players. The study suggested that the more sleep an individual gets, the greater the next-day improvements in alertness and performance, and the less "recovery sleep" is needed to restore alertness and performance to normal levels.
Another study on healthy, normally-sleeping young adults found that sleep extension significantly improved fatigue below baseline levels. However, it did not improve subjective sleepiness/alertness or mood. The study also demonstrated that one week of sleep extension had no detectable effect on self-reported mood.
Overall, while the concept of "sleep banking" or "sleep debt" may not be accurate, sleep extension has been shown to improve alertness and performance. This can be especially useful when individuals know they will be facing sleep deprivation in the future, such as during a long journey or when expecting a new baby.

Sleep banking and the two-process model
Sleep banking is a strategy that may help counterbalance sleep deprivation. The concept revolves around the idea of storing extra sleep for future use, akin to saving money in a bank account. While the idea of sleep banking is intriguing, it is essential to understand its underlying mechanisms and how it fits within the framework of sleep regulation. This is where the two-process model comes into play.
The two-process model of sleep regulation posits that sleep is governed by the interplay of two distinct processes: a sleep-wake-dependent homeostatic process (Process S) and a circadian process controlled by the body's internal clock (Process C). Process S dictates the drive to sleep based on the amount of prior wakefulness, while Process C aligns sleep timing with the body's 24-hour circadian rhythm. These two processes interact to determine when we fall asleep, when we wake up, and the quality of our waking neurocognitive functions.
The two-process model suggests the existence of a stable set-point for sleep. Deviations from this set-point, such as sleep deprivation or excessive sleep, trigger a proportional response in sleep amount and intensity until equilibrium is restored. This notion of a stable set-point seems at odds with the concept of sleep banking, which implies that the set-point can be altered. However, it is important to note that the existing data neither confirms nor refutes this possibility.
While the two-process model is a valuable framework for understanding sleep regulation, it is traditionally applied on a shorter time scale of around 24 hours, unlike sleep banking, which operates over several days. Future sleep banking studies that incorporate sleep/wake EEG and mathematical modelling of Process S will likely shed more light on how these two concepts intertwine.

Sleep banking and neurobehavioural functions
Sleep banking is a strategy that may help individuals counterbalance sleep deprivation. The concept revolves around storing up or "banking" sleep hours when one has the opportunity, similar to depositing money in a bank account. This reserve can then be utilized during periods of reduced sleep. For instance, individuals may strive for an extra hour or 90 minutes of sleep each night in the week leading up to anticipated sleep deprivation.
Neurobiologist Allison Brager, author of "Meathead: Unraveling the Athletic Brain," supports this concept, likening it to a bank account. She asserts that the more sleep deposited, the more can be withdrawn without incurring a negative balance. Approximately 30 published studies conducted in laboratories and at the Walter Reed National Military Medical Center have supported this idea. These studies found that individuals who obtained an additional hour of sleep each night leading up to sleep deprivation performed better on tasks than those who did not.
However, the notion of sleep banking remains controversial. Dr. Rafael Pelayo, a clinical professor of sleep medicine at Stanford University School of Medicine, argues that individuals cannot truly bank sleep. Instead, he suggests that those who practice sleep banking are merely repaying their sleep debt, and returning to a normal level of sleep improves their alertness and attention. The two-process model, traditionally used to describe the dynamics of sleep and wakefulness over a short time scale, implies the existence of a stable set-point. This set-point theory suggests that any deviation from a certain level of sleep would trigger a proportional response to reestablish equilibrium. As a result, the concept of sleep banking, which implies altering the set point, may appear inconsistent with this fundamental postulate.
While the effectiveness of sleep banking in creating a positive sleep balance is still under debate, it has sparked important discussions about the impact of sleep on neurobehavioural functions. Sleep banking studies that incorporate sleep/wake EEG and mathematical modelling of Process S may provide valuable insights into the dynamics between sleep and wakefulness and their effects on neurobehavioural functions.
