An extra half-hour of sleep shown to improve mindfulness
A new study of nurses shows the importance of sleep—and staying aware on the job.
- A study of nurses found that an extra 29 minutes of sleep dramatically improved job-related mindfulness.
- Nurses that reported higher mindfulness scores were 66 percent less likely to experience symptoms of insomnia.
- Roughly 70 million American adults suffer from some form of sleep disorder.
Health care requires extreme attention to detail. Surgeons must pay particular attention to every move. Orthopedic surgeons can easily miss revealing details on an x-ray. Perhaps no job in health care requires more multitasking than nursing. Mindfulness is especially important in this field.
A new study from the University of South Florida's School of Aging Studies, led by assistant professor Soomi Lee and published in the journal Sleep Health, uncovers a critical best practice for nurses: sleep. In this study of 61 full-time nurses in U.S. hospitals, an extra 29 minutes of sleep every night helped these frontline workers be more mindful while on the job.
Mindfulness requires complete attention to detail on the moment in front of you. Derived from Buddhist philosophy, mindfulness became vogue in psychotherapy circles in the seventies, predominantly due to the work of Jon Kabat-Zinn. While the word tends to invoke images of seated meditation practice, mindfulness can be done at all times by anyone, making this focus on nurses especially intriguing.
Nurses are expert multitaskers—the antithesis of mindfulness, though given their job duties, juggling multiple obligations comes with the territory. It's easy to overlook a blood test or temperature check when the hospital floor is slammed. Mindfulness plays an important role in helping them stay on track without becoming overwhelmed by tasks.
Thanks to long and often grueling shifts—some nurses can be on the floor for 24 hours—sleep problems are common. This is especially true during the COVID-19 pandemic; the emotional toll is causing mental health problems for all frontline workers, which can result in a lack of sleep. A vicious cycle ensues.
For the study, Lee and her team tracked the nurses via self-reported questionnaires on their phones, examining eight sleep variables across five dimensions: satisfaction, alertness, timing, efficiency, and duration. They also reported their levels of attention and awareness while at work. The nurses answered mindfulness and sleepiness questions three times a day for two weeks.

It shouldn't be surprising that more sleep leads to greater capacity to focus. Specifically, the nurses that reported greater sleep sufficiency, higher sleep quality, and less insomnia fared best the next day at work. The goal, however, was to track more than awareness. As Lee notes,
"Mindful attention is beyond just being awake. It indicates attentional control and self-regulation that facilitates sensitivity and adaptive adjustment to environmental and internal cues, which are essential when providing mindful care to patients and effectively dealing with stressful situations."
In a sort of feedback loop, the nurses that reported higher mindfulness scores were 66 percent less likely to experience symptoms of insomnia. About one-third of American adults sleep less than six hours per night. Problems ranging from cognitive decline and weight gain to automobile accidents and immune system issues result from too little sleep.
If car crashes are more likely when drivers aren't sleeping enough, just think of the number of workplace accidents—an especially harrowing prospect if your job requires sticking needles into patients and monitoring their vitals. With an estimated 70 million Americans suffering from some form of sleep disorder, this is an under-discussed public health crisis.
The feedback loop from Lee's study shows the necessity of cultivating both more awareness and sleeping better. When you work in health care, it's not only your health on the line.

What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.
- Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
- That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
- We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
The inherent worth of all human beings<p>Human dignity is the inherent worth of each individual human being. Recognizing human dignity means respecting human beings' special value—value that sets us apart from other animals; value that is intrinsic and cannot be lost.</p> <p>Liberalism—the broad political philosophy that organizes society around liberty, justice, and equality—is rooted in the idea of human dignity. Liberalism assumes each of our lives, plans, and preferences have some unimpeachable value, not because of any objective evaluation or contribution to a greater good, but simply because they belong to a human being. We are human, and therefore deserving of a baseline level of respect. </p> <p>Because so many of us take human dignity for granted—just a fact of our humanness—it's usually only when someone's dignity is ignored or violated that we feel compelled to talk about it. </p> <p>But human dignity means more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose—a freedom that can be hampered by restrictive social institutions or the tyranny of the majority. The liberal ideal of the good society is not just peaceful but also pluralistic: It is a society in which we respect others' right to think and live differently than we do.</p>

The future of dignity<p>Around the world, people are still working toward the full and equal recognition of human dignity. Every year, new speeches and writings help us understand what dignity is—not only what it looks like when dignity is violated but also what it looks like when dignity is honored. In his posthumous essay, Congressman Lewis wrote, "When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war."</p> <p>The more we talk about human dignity, the better we understand it. And the sooner we can make progress toward a shared vision of peace, freedom, and mutual respect for all. </p>
With just a few strategical tweaks, the Nazis could have won one of World War II's most decisive battles.
- The Battle of Britain is widely recognized as one of the most significant battles that occurred during World War II. It marked the first major victory of the Allied forces and shifted the tide of the war.
- Historians, however, have long debated the deciding factor in the British victory and German defeat.
- A new mathematical model took into account numerous alternative tactics that the German's could have made and found that just two tweaks stood between them and victory over Britain.
Two strategic blunders<p>Now, historians and mathematicians from York St. John University have collaborated to produce <a href="http://www-users.york.ac.uk/~nm15/bootstrapBoB%20AAMS.docx" target="_blank">a statistical model (docx download)</a> capable of calculating what the likely outcomes of the Battle of Britain would have been had the circumstances been different. </p><p>Would the German war effort have fared better had they not bombed Britain at all? What if Hitler had begun his bombing campaign earlier, even by just a few weeks? What if they had focused their targets on RAF airfields for the entire course of the battle? Using a statistical technique called weighted bootstrapping, the researchers studied these and other alternatives.</p><p>"The weighted bootstrap technique allowed us to model alternative campaigns in which the Luftwaffe prolongs or contracts the different phases of the battle and varies its targets," said co-author Dr. Jaime Wood in a <a href="https://www.york.ac.uk/news-and-events/news/2020/research/mathematicians-battle-britain-what-if-scenarios/" target="_blank">statement</a>. Based on the different strategic decisions that the German forces could have made, the researchers' model enabled them to predict the likelihood that the events of a given day of fighting would or would not occur.</p><p>"The Luftwaffe would only have been able to make the necessary bases in France available to launch an air attack on Britain in June at the earliest, so our alternative campaign brings forward the air campaign by three weeks," continued Wood. "We tested the impact of this and the other counterfactuals by varying the probabilities with which we choose individual days."</p><p>Ultimately, two strategic tweaks shifted the odds significantly towards the Germans' favor. Had the German forces started their campaign earlier in the year and had they consistently targeted RAF airfields, an Allied victory would have been extremely unlikely.</p><p>Say the odds of a British victory in the real-world Battle of Britain stood at 50-50 (there's no real way of knowing what the actual odds are, so we'll just have to select an arbitrary figure). If this were the case, changing the start date of the campaign and focusing only on airfields would have reduced British chances at victory to just 10 percent. Even if a British victory stood at 98 percent, these changes would have cut them down to just 34 percent.</p>
A tool for understanding history<p>This technique, said co-author Niall Mackay, "demonstrates just how finely-balanced the outcomes of some of the biggest moments of history were. Even when we use the actual days' events of the battle, make a small change of timing or emphasis to the arrangement of those days and things might have turned out very differently."</p><p>The researchers also claimed that their technique could be applied to other uncertain historical events. "Weighted bootstrapping can provide a natural and intuitive tool for historians to investigate unrealized possibilities, informing historical controversies and debates," said Mackay.</p><p>Using this technique, researchers can evaluate other what-ifs and gain insight into how differently influential events could have turned out if only the slightest things had changed. For now, at least, we can all be thankful that Hitler underestimated Britain's grit.</p>
