Per World Health Organization – 40% of Cancers are Preventable

According to the World Health Organization, cancer is responsible for one out of every eight deaths worldwide.  Over 20% are related to viruses, like the  human papillomavirus, or HPV, which causes cervical cancer, or hepatitis infections that cause stomach and liver cancer.  Read more at The Boston Globe.

Why is this especially important to shift workers?  Because shift workers’ are more prone to smoke, drink alcohol to cope with working shifts, and they are less likely to focus on maintaining good nutrition.  To avoid cancers in the lungs, colon, and breasts, people should  stop smoking, limit their alcohol consumption, avoid too much sun, and maintain a healthy weight through diet and exercise.

Human Fatigue in Shift Work Operations – Causes and Solutions

“Weariness or exhaustion from labor, exertion, or stress.”

-          Per Merriam-Webster 

Fatigue is a lack of energy or motivation.  It’s severity can range from the exhaustion resulting from chronic fatigue syndrome (CFS) to the weariness that results from working all day and taking care of a baby during the night – or for many shift workers, working all night and taking care of the home front during the day! 

This posting looks at CFS and regular, everyday fatigue, assessing how working shift work causes fatigue and what shift workers can do about it. Read this article…

This Emotional Life – Following up on “Stumbling on Happiness”

Daniel Gilbert, professor at Harvard and best selling author of “Stumbling on Happiness,” hosts this PBS show, This Emotional Life, starting Monday, January 4th.  The show will explore ways to improve social relationships, cope with emotional issues, and become more positive and resilient as individuals. 

Many people from all walks of life are profiled, including every day moms, dads, and workers, and famous people like Katie Couric and Richard Gere.  If you have to work when the show is aired, you can  either tape it at home, or purchase the series at http://www.shoppbs.org/product/index.jsp?productId=3914596. 

In Stumbling on Happiness, Gilbert shares with us facts about the way our mind works.  Gilbert, a Harvard University Psychology professor, is particularily interested in the shortcomings of our imaginations.  He says we’re much too accepting of the conclusions of our imaginations.   He notes that our imaginations are really bad at telling us how we will think when the future finally comes. And our personal experiences aren’t nearly as good at correcting these errors as we thing they are.

A Great Book to Read over the Holidays – “My Stroke of Insight,” by Jill Bolte Taylor

Book Review – My Stroke of Insight – a Brain Scientist’s Personal Journey, by Jill Bolte Taylor, Ph.D.,

Taylor’s book provides a unique education about our brains, in particular, about how the two different hemispheres of our brains work – together and independently.  Taylor provides insight into the impact of impaired brain functioning, something that is critical to the health and safety of shift workers and to the success of shift work operations.  Shift workers are known to exist on less than the optimal amount of sleep ~ typically 5 hours versus 7-8 hours; while obviously not as severe as a stroke, sleep deprivation has been shown to have a significant negative impact on the brain’s ability to perform.

There have been many studies on the impact of sleep deprivation on the brain.  In one study (Dai-Jin Kim et al, International Journal of Neuroscience, 2001), sleep deprived subjects showed no differences in distractibility, physical and visual functioning, reading, writing, arithmetic, and intellectual processes when compared to study participants who were allowed to sleep.  However, cognitive functions such as motor skills, rhythm, receptive and expressive speech, memory and complex verbal and arithmetic functions were decreased after sleep deprivation.  In another study (Drummond et al, Nature, 2000), researchers found “dynamic, compensatory changes in cerebral activation during verbal learning after sleep deprivation.” The researchers found that the prefrontal cortex (controls decision making and following through with thoughts and actions) and the parietal lobes (sensory integration) were key factors in allowing the subjects to function after sleep deprivation.  In other words, our brains work hard to compensate when we are sleep deprived and this may explain why some people claim they can exist on very little sleep – something we don’t recommend.

Try and Take Full Advantage of Recovery Days – Especially over the Holidays

There have been a number of studies done on the importance of recovery days after working shifts. It’s logical….our bodies (and minds) can’t work at odd hours, long days, or rapidly rotating schedules, without being seriously impacted. Now, a few days before Christmas and a week before New Year’s, almost everyone is suffering from depleted energy. But as we continue to push ourselves to persevere, saying, “Just hold on and get through the holidays; it’ll be over soon,” we seek our ways to cope. Often we do this in a robotic-like fashion, not even consciously. We might drink a little too much hoping to calm ourselves down for sleep, pop pain-killers to reduce our aches and pains from all the running around, or skip dinner in favor of Doritos because we’re too tired to cook.

Sound familiar? These are the feelings, vegetative state, and survival tactics most shift workers face on a regular basis, not just around the holidays. If you work shifts, you know.

Back to recovery days……

New Shift Work Information on Weight Loss and Apnea, Craving a Smoke, and the Combined Effects of Caffeine and Alcohol

During the last month three new studies potentially impacting a number of shift workers have been released. Here are the top level findings:

1. A dramatic weight loss can improve moderate to severe sleep apnea in obese men.

2. Craving a cigarette while performing a cognitive task increases the chances of a person’s mind wandering and they don’t even realize it is happening.

3. Drinking a cup of coffee may actually make it harder for people to realize they’re drunk.

Read on to understand why these are important studies for shift workers.

Can Music Calm a Shift Worker’s Soul – and Improve Sleep as Well?

Where can you find Coldplay, Betty Buckley, The Beastie Boys, Bruce Hornsby, and Vanessa Carleton all working together? Seems like an unlikely group, doesn’t it?

These musicians and many other creative types are big supporters of the Institute for Music and Neurologic Function (IMNF). Created in 1995, IMNF was founded “to restore, maintain and improve people’s physical, emotional and neurologic functioning through the systematic use of music.” IMNF collaborates with researchers and practitioners around the world to advance the understanding and application of the power of music to promote healing and wellness. Some of IMNF’s most significant research and startling findings are in the areas of music and its impact on language, memory, and recovery from nerve injury.

How does music affect shift workers? Should it be listened to at work? Does it help you fall asleep? Can it lower stress when coping with variable schedules?

New Research Proves – You are what you eat – More than Ever!

Australian researchers overseeing a study published last month in the Archives of Internal Medicine found that eating more carbohydrates than fat and protein increases serotonin production in the brain. Serotonin is a chemical that has been linked with improved mood and mental health. Shift workers have been found to have lower levels of serotonin than daytime employees. Does this mean that people working the night shift should run out and stock up on potatoes, beans, rice, pasta, and bread? YES

In the study, half of the participants spent a year following a diet low in fat and high in carbohydrates. The other half went on a low-carbohydrate, high-fat diet. The participants in both groups lost 30 pounds on average and generally said they felt happier after two months on the diet. But after continuing to diet for a year, the people who ate less fat (butter, steak, pork, veal) and more carbs (pasta and potatoes) reported feeling happier and less depressed and anxious than they had before. The other group, who ate more fat and fewer carbohydrates, felt that their moods were worse than they’d been before.

The book, “The Serotonin Power Diet,’’ by Judith J. Wurtman, PhD and Nina T. Fruszajer, MD, published in December of 2006 beat the Australians to the punch line. The book’s authors state on the home page of their website, “Our brains makes serotonin when you eat foods such as pretzels, pasta, rice, and potatoes – in the right amounts, at the right times of the day, and without protein.” And they also say that serotonin curbs your appetite, restores mental energy, and soothes emotional stress. The authors recommend that “30-60 minutes before your next meal, munch on a serotonin soothing snack: pretzels, cheerios, popcorn, or cherry licorice bites. Notice how it takes the edge off your appetite and energizes you.”

WSJ Covers Heart Risk at Work and Seasonal Affective Disorder

There were two articles in the Wall Street Journal today that are significant to shift workers. One story is about Seasonal Affective Disorder (SAD), and the other’s about a new study reporting that men who didn’t confront colleagues or bosses who treated them unfairly doubled their risk of heart attack.

Seasonal Affective Disorder – the article states that SAD “affects an estimated 6% of Americans, causing depression, lethargy, irritability and a desire to avoid social situations. It can also create an urge to overeat, particularly carbohydrates. As many as 15% of people in the U.S. may have a milder version that includes only some of these symptoms.” What the article leaves out, that all shift workers know, is that SAD symptoms are routinely felt by workers at jobs outside the normal day-time hours of 7 a.m. to 7 p.m. See more about this in our articles on Vitamin D and Serotonin.

Reducing Heart Risk with Confrontation – the lead researcher from Stockholm University and her research partners asked 2,755 men how they typically responded to unfair treatment at work. Those who said they just let it pass and said/did nothing had significantly more heart attacks during the next ten years. After adjusting for age, socio-economic factors, risk behaviors, job strain, and biological risk factors, the risk of heart and death from a cardiovascular event was 2.3 times greater than it was for those who said they confronted those treating them unfairly. Read more about how shift workers can manage stress on the job and about controlling bullying at work.

The Problem of Migraines and Shift Work

Each year upwards of 90% of the U.S. population will feel headache pain and 13% will suffer from a migraine. Nearly 30 million Americans have migraines. Researchers from Johns Hopkins, after pooling results from 21 studies, involving 622,381 men and women, have found that migraine headaches are associated with more than double the likelihood of the most common kind of stroke – those occurring when blood supply to the brain is suddenly cut off by the buildup of plaque or a blood clot.

The National Headache Association estimates that headaches cost up to $17 billion dollars in absenteeism, lost productivity, and medical expenses each year. Ninety percent of respondents to a NHA 2008 survey indicated that headaches affected their work performance. Migraines are triggered by many different issues such as stress, environmental factors (e.g. lighting and eye strain), depression, or certain foods and some medications. One major factor in the development of migraines is lack of sleep.

Are shift workers more likely to suffer from migraines?

Happy Thanksgiving from Working Nights – an Idea for Getting Through Dinner!

Holiday dinners with family can be easily ruined. A political debate might erupt at the table over health care reform, Obama’s job rating, or how people feel about Sarah Palin. Perhaps a new husband or wife isn’t liked, so half the table ignores them while the other goes overboard to make them feel comfortable. Some people actually have the nerve to state that they don’t like the food – right in front of the chef. Maybe someone has dietary issues so the ingredients of every dish have to be reviewed before they take a bite. How about the nurse or firefighter who worked the entire night before and can’t stay awake at the table or has a short fuse as a result of being tired? There might be sadness over a recent death or heartbreak from missing someone who’s overseas with the military. What about those screaming kids banging their silverware on the crystal stemware or china plates? Sometimes you wish you’d stayed home.

Here’s a new holiday dinner sanity idea.

Differences Between Men and Women at Work – We Need Both Sexes!

Women continue to be a significant force in the workplace; the numbers of working women are gaining on working men. The Bureau of Labor statistics reported this June that women held 49.8% of the U.S jobs. Here are some trends:

• Women have been gaining the vast majority of positions in the few sectors of the economy that are growing (health care, education, and government).

• Through June, men had lost 74% of the 6.4 million jobs eliminated since the recession began in December 2007. Men have lost more than 3 million jobs in construction and manufacturing alone.

• The gender hiring trend is really extreme in local government’s 14.6 million-person workforce. Cities, schools, water authorities and other local jurisdictions have cut 86,000 men during the recession – while adding 167,000 women.

• As a result, at the end of October the jobless rate for women was 8.1% compared to 10.7% for men.

What do these trends mean for men?

Shift Work and Divorce – Does the Work Schedule Really Make a Difference?

Divorce.  It’s not a fun topic for anyone. 

By now most of us have read that we’re better off if we’re married.  According to the Center for Disease Control, married people tend to have lower mortality rates, exhibit less risky behavior, are more likely to monitor their health, comply with necessary medical routines, have sex more often and experience more satisfaction with their sexual lives, save more and earn more.  On a national level, the Census Bureau reports that a shrinking share of Americans are married – only 52% of males and 48% of females were married in 2008. The proportion of Americans who are currently married has been decreasing for decades and is lower than it has been in at least half a century.  The median duration of a marriage in 2008 was 18 years. In 2008, 9% of men were divorced and 12% of women were. 

So why don’t we stick with our marriages?  And, is it true that maintaining a marriage is more difficult for shift workers?
