Judgment and Safety | Need Sleep. A Tragic Example. Nineteen- year- old Candy Lynn Baldwin was well acquainted with the 8. Baltimore, Maryland, and her home in the Eastern Shore town of Millington. She had made the drive, which crosses the Chesapeake Bay, many times. On Saturday evening, August 9, 2. Friday night and full day Saturday preparing for and attending her mother's wedding, Baldwin and a cousin set out for Baltimore. They didn't give their return trip much thought, even though they knew they would be returning late. Just before 4: 0. Baldwin steered her 1. Chevrolet Camaro onto the Chesapeake Bay Bridge toward home. By that time, she had been awake for many hours straight. In addition, her internal biological clock, a part of the brain that helps control the timing of alertness and sleep, was likely sending out strong signals that her body needed to sleep. At the same time, John Short was pulling onto the far end of the massive bridge, driving a semi- truck full of refrigerated chicken. On this particular night, maintenance had forced both directions of traffic onto the same eastbound span. As the two vehicles converged at highway speeds, Baldwin nodded off and veered across the centerline, far too quickly for Short to avoid. Short's attempt to avoid a crash, and the subsequent collision, sent his truck hurtling into the opposite lane before smashing through a guardrail and plunging into the water below. He died of multiple injuries and drowning, according to autopsy reports. Baldwin's cousin escaped relatively unscathed, receiving only minor injuries. Baldwin herself sustained two broken kneecaps and damage to her spleen and liver. She has no recollection of the crash. The book of hours has its ultimate origin in the Psalter, which monks and nuns were required to recite. By the 12th century this had developed into the breviary, with weekly cycles of psalms, prayers, hymns, antiphons, and. The Satanic Rebellion: Background to the Tribulation.

Although this is an extreme and tragic example of the hazards of driving while sleep deprived, the circumstances that led up to Baldwin's accident are all too common. According to a National Sleep Foundation survey, one- third of all adult drivers say they have fallen asleep at the wheel. On the basis of the best available research, the Institute of Medicine estimates that drowsy driving is responsible for 2. That means that drowsy driving causes 1 million crashes, 5. U. S. 2. Driving is not the only activity negatively impacted by insufficient sleep. Virtually any task or profession that requires alertness and sound judgment may be affected by too little sleep. The medical profession, for example, is notorious for the long, sleepless hours required of doctors, nurses, and other healthcare providers, and this has an impact on the quality of care patients receive. Although the precise number of medical errors attributable to insufficient sleep is unknown, a randomized, controlled trial at Harvard's Brigham and Women’s Hospital found that more than one- quarter of the errors that interns (first- year doctors- in- training) made in the care of ICU patients were attributable to their traditional extreme work schedules. Given that medical errors are responsible for as many as 9. U. S. 5, the reduction of doctors' and nurses' sleep deprivation has become a major public health issue. How Poor Sleep Affects Performance. Several sleep- related factors can affect an individual's ability to stay alert and perform a task safely and competently. The first is the number of hours that person has been continuously awake. With each hour of wakefulness, the drive to sleep increases and alertness fades. Another common factor is insufficient sleep on a regular basis, also known as chronic sleep deprivation. Scientists have found that a small nightly decrease in sleep has serious cumulative effects; for instance, a week and a half spent sleeping just six hours per night, rather than seven to nine, can result in the same level of impairment on the tenth day as being awake for the previous 2. Another factor is an individual's internal biological clock. Shift workers, in particular, are affected by the timing of their internal clock, especially when they try to be alert when their internal clock says they should be sleeping, or when they try to sleep when their clock says they should be awake. Drowsy or Drunk, the Effects Are Similar. Studies have shown that staying awake for just 1. European countries). This level of impairment slows an individual's reaction time by about 5. Twenty- four hours of continuous wakefulness induces impairments in performance equivalent to those induced by a blood- alcohol level of 0. United States. 7. Perhaps even more profound is the effect of poor sleep on judgment. The prefrontal cortex, an area near the front of the brain responsible for logical reasoning and complex thought, seems particularly vulnerable to sleep deprivation. Experts think this may explain why people typically have such a hard time recognizing their own fatigue and level of impairment. Like the drunk driver who thinks he or she is just fine to drive, the tired driver is not always the best judge of his or her ability to operate a vehicle safely.

Research has shown that bad sleep can adversely affect a person’s physical health and emotional well- being. However, the amount of sleep one gets can also influence his or her decision- making. A study published in the March 1 issue of the journal SLEEP finds that sleep deprivation impairs the ability to integrate emotion and cognition to guide moral judgments. The study, conducted by William D. S. Killgore, Ph. D, and colleagues at the Walter Reed Army Institute of Research, was focused on 2. Compared to baseline, sleep deprivation resulted in significantly longer response latencies (suggesting greater difficulty deciding upon a course of action) for moral personal dilemmas. The findings suggest that continuous wakefulness has a particularly debilitating effect on judgment and decision making processes that depend heavily upon the integration of emotion with cognition, said Killgore, adding that the results provide further support to the hypothesis that sleep loss is particularly disruptive to the ventromedial prefrontal regions of the brain, which are important for the integration of affect and cognition in the service of judgment and decision making.“Most of us are confronted with moral dilemmas nearly every day, although the majority of these choices are minor and of little consequence,” said Killgore. Although such decisions are inextricably steeped in social, emotional, religious and moral values, and their correct courses of action cannot be determined through scientific inquiry, it is well within the realm of science to ask how the brain goes about solving such dilemmas and what factors, whether internal or external to the individual, contribute to the judgments and decisions that are ultimately reached. According to Dr. Killgore, these findings do not suggest that sleep deprivation leads to a decline in “morality” or in the quality of moral beliefs, but a latency to respond and the change in the leniency or permissiveness of response style as evidenced by the tendency to decide that particular courses of action were “appropriate” before and after sleep loss.“Our results simply suggest that when sleep deprived, individuals appear to be selectively slower in their deliberations about moral personal dilemmas relative to other types of dilemmas,” said Killgore. The present findings may have implications for those in occupations that frequently require periods of extended sleep loss and in which real- world moral dilemmas may be encountered (e. Killgore. When sleep deprived, such personnel may experience greater difficulty reaching morally based decisions under emotionally evocative circumstances and may be prone to choosing courses of action that differ from those that they would have chosen in a fully rested state, added Killgore. Experts recommend that adults get seven- to- eight hours of sleep on a nightly basis. Those who think they might have a sleep disorder are urged to discuss their problem with their primary care physician, who will issue a referral to a sleep specialist.
