The negative effects of sleep deprivation in human beings

Fatigue is the feeling of tiredness and decreased energy that results from inadequate sleep time or poor quality of sleep. Fatigue can also result from increased work intensity or long work hours.

Sleep deprivation has long been known to impair various cognitive functions, including mood, motivation, response time, and initiative.

The need for sleep varies individually. The absolute amount of sleep required per 24 hours is generally understood to be a minimum of 5 hours. Most healthy adults need between 7.

What Are Sleep Deprivation and Deficiency?

At least two components regulate human sleep: The physiologic drive for sleep increases with time awake and decreases during time asleep. As awake time surpasses 12—16 consecutive hours, the drive for sleep becomes increasingly powerful. Wakefulness, like sleep, also has a circadian rhythm: Indeed, the strength of the circadian cycle has led researchers to argue that human beings are "biologically hard-wired to be active during the day and sleepy at night.

Working at night must therefore be regarded as an inherently unnatural act. Principles and Practice of Sleep Medicine. Given the importance of sleep and its known effect on cognitive performance, the link between sleep and patient safety has garnered considerable attention.

InAHRQ funded the National Academy of Medicine to synthesize evidence on medical resident schedules and health care safety as well as to recommend strategies to enable optimization of work schedules and patient safety.

In this report, fatigue is characterized as a latent hazard and "an unsafe condition" in health care that leads to increased medical error rates. In a classic review of sleep deprivation and decision-making, investigators argued that effective performance in health care environments requires naturalistic decision-making and situation awareness.

This type of thinking involves assessing and planning for rapidly changing situations, forming mental models and future status projections, evaluating risks, appreciating the consequences of actions, and rapidly revising plans in light of changing information.

These cognitive activities place significant loads on prefrontal cortex functions, such as memory and tracking capacity, which are particularly sensitive to sleep deprivation and related fatigue. Both acute and chronic sleep deprivation result in cumulative deficits in executive function and mood, as well as heightened irritability—and all of these can impair communication and coordination in health care teams.

Chronic sleep deprivation can also contribute to burnoutwhich is increasingly recognized as a threat to patient safety. In contrast to dynamic, naturalistic decision-making, certain types of cognitive performance are less sensitive to sleep deprivation.

Complex tasks that are rule-based and interesting or require critical reasoning in logical well-practiced tasks show less sleep-related degradation of performance.

Thus in the context of acute sleep deprivation, individuals may be better able to compensate for cognitive impairment when tasks are complex and interesting e. On the other hand, they may be more susceptible when tasks are rote or rely primarily on vigilance such as reviewing laboratory tests or ordering medications.

Insomnia, Parasomnias, and the Insanity of Chronic Sleep Disorders

This difference may explain why evidence on the effects of acute sleep deprivation e. The effects of sleep deprivation will become increasingly important as health care moves to more shift-based physician staffing.

There is good evidence of increased nursing errors when shifts last longer than 12 hours, nurses work overtime, or nurses do not receive adequate rest breaks. Similarly, in a classic study of resident work hoursLandrigan and colleagues found medical and diagnostic error were significantly more common in residents working traditional long shifts of more than 24 hours.

Studies—including research supported by AHRQ—have shown that residents make fewer errors in the setting of closely monitored, comprehensive interventions to reduce work hours and improve sleep.

Current Context Despite ongoing controversies regarding the impact of resident work hour restrictions and physician sleep deprivation on surgical outcomes, The Joint Commission has issued several reports alerting health care providers and the public to the potential for serious adverse effects of lack of sleep.

In a Sentinel Event AlertThe Joint Commission called on health care organizations to take steps to mitigate the impact of extended work hours on clinician sleep deprivation and fatigue. These steps include conducting a risk assessment; ensuring robust handoff practices; involving staff in design of work schedules; implementing a fatigue management plan including strategic use of caffeine and planned naps; educating personnel about sleep hygiene; and ensuring an adequate environment for sleep breaks.

However, more evidence is needed to determine optimal practices for schedulingplanned nappingand other fatigue mitigation strategies. One challenge in addressing sleep deprivation among clinicians is that adequate sleep time requires a combination of effective organizational policies regarding work hours, shift rotation, and sleep policiesas well as personal commitment to good sleep habits.

Work hour restrictions alone will be ineffective if, when working nights, clinicians do not also limit daytime activities in order to obtain adequate sleep. Related Patient Safety Primers.Transcript of Negative Effects of Computers on Human Beings.
