New Information about Sleep and Shift Work

We’ve written extensively about the challenges many shift workers face as a result of not getting enough sleep. A few new studies provide more insight for those with sleep challenges. Read this article…

Seratonin Levels Feed Anger

Many studies have shown that low levels of serotonin are also associated with anger, depression and anxiety. Fluctuations of serotonin levels in the brain, which often occur when someone hasn’t eaten or is feeling stressed, affect brain regions that enable people to regulate anger. So when stressed or hungry, people are often unable to manage their anger. This is especially relevant to shift workers as the stress of working outside regular daytime hours is significant and good eating habits of shift workers are often lacking (self-reported). A new study published September 15, 2011 in the journal Biological Psychiatry has shown that individuals who might be predisposed to aggression were the most sensitive to changes in serotonin depletion.

Do you Learn from your Mistakes?

People who think they will learn from their mistakes have a different brain reaction to mistakes than people who think intelligence is fixed. Jason S. Moser, of Michigan State University, who collaborated on a new study, found that people who think intelligence is malleable say things like, “When the going gets tough, I put in more effort” or “If I make a mistake, I try to learn and figure it out.” On the other hand, people who think that they can’t get smarter will not take opportunities to learn from their mistakes. People who think they can learn from their mistakes did better after making a mistake; they successfully bounced back after an error. Their brains also reacted differently, producing a bigger second signal, the one that says “I see that I’ve made a mistake, so I should pay more attention” Moser says.

Dealing with People on a Power Trip?

Individuals in roles that possess power but lack status have a tendency to engage in activities that demean others. The experiment demonstrated that “individuals in high-power/low-status roles chose more demeaning activities for their partners than did those in any other combination of power and status roles.” It feels bad to be in a low status position and the power that goes with that role gives these workers a way to take action on those negative feelings.

Want Happy Memories this Holiday Season? Consider Scrimping on Sleep!

Sleep plays a crucial role in the development of memories….but lack of sleep may actually help you put your bad experiences aside!

Researchers showed healthy volunteers video clips of both safe driving and unexpected motor vehicle accidents. After viewing the clips, half of the volunteers were deprived of sleep while the other half received a normal night’s sleep. Sleep deprivation eliminated the fear-associated memories. The researchers suggest this may be due to the lack of memory consolidation that typically occurs during sleep.

So, if you’re not looking forward to unsettling holiday parties, stressful family events, too much overtime work, or dealing with the loss of a loved one – take it easy. But don’t be too focused on getting extra sleep. A little sleep deprivation may be a good thing. Just make sure you’re rested enough that you’re ready for what you need to do – whether work or play!

Happy Holidays from WorkingNights.

It’s Important to Talk with your Doctor about Working Shift Work

If you’ve read much of the material on this blog, you know that working shift work contributes to many challenging, but manageable, health and lifestyle issues.  One way to make sure you manage your own unique circumstances is by talking with your health practitioner about the fact you work shifts and raising any concerns you have about shift work.  A recent study by the University of Illinois at Chicago and the VA Center for Management of Complex Chronic Care found that physicians tend to follow a fairly standard approach to care for most health conditions.  Physicians do not generally take into account  a particular patient’s situation or life context, so the fact that a patient works shift work is not likely to enter the doctor’s radar screen.  But, it’s critical for shift workers to have doctors who understand the unique challenges of working shift work.

Some of the special issues shift workers can face include:

1.  Sleep disturbances from work schedules distrupting sleep schedules.

2. Lower levels of Vitamin D resulting from lack of exposure to sunlight.

3. Overweight due to lack of nutritional food when working nights.

4. Higher rates of divorce due to lifestyle challenges of working shifts.

5. Increased risk for depression arising from lower levels of seratonin.

Read other posts throughout this blog for more areas of risk when working shifts. 

Next time you go to your health practitioner, bring a list of your concerns and be vocal about them with your provider.  Make sure your doctor or nurse practitioner knows you work shift work.  The University of Illinois at Chicago and the VA Center for Management of Complex Chronic Care study found that doctors were more likely to respond to biomedical facts – e.g. test results - than to contextual red flags - such as I work  shift work and I’m concerned about my increased risk for cardiac problems even though I don’t have any family members with heart health issues.  Both biomedical facts and contextual red flags are equally important to planning appropriate care, according to the study researchers.  By planning care with your provider you can prevent shift work challenges from impacting your health and lifestyle.

What’s Green and Beige and Eaten All Over?

Pistachios! 

Researchers report that up to 95% of people do not get enough potassium.  Failing to meet the standard recommended daily intake levels can lead muscular cramps, twitching, and weakness, poor reflexes, fatigue, kidney failure, lung failure, and cardiac arrest. Also, too little potassium can result in insomnia, cognitive processing delays, and depression.  Getting enough potassium is important for shift workers who are already susceptible to sleep disorders, such as insomnia and restless leg syndrome, as well as fatigue.  When working shift work, it’s important to pay attention to eating nutritiously, which isn’t always easy to do.  Planning meals ahead is often the only way to guarantee a balanced diet when working nights, in particular.

How Do You React to Stress?

Work can be hugely stressful. In fact, twenty-five percent of Americans say that their job is their greatest contributor to the angst in their lives.  And, clearly there are other stresses too.  Pressure, anxiety, and tension can result in headaches, sleep disturbances, difficulty concentrating, short tempers, upset stomachs, low morale, and general life dissatisfaction.  Shift workers can experience extra stress as a result of working variable hours, getting less sleep, having little access to family members and friends, leading to increased isolation and lack of support.

Stress can be reduced though, and here are some ideas to help. Read this article…

Insomniacs with Nighttime Awakenings Have a Huge Impact on Health Care Costs and Workforce Management

Did you know that 30-40% of adults report some symptoms of insomnia within any given year?  But that’s nothing…..according to the National Sleep Foundation, over 60% of people who work shifts report that they suffer from insomnia.  And, 30% of shift workers claim that they’re excessively tired all the time.  People who work shifts are twice as likely to fall asleep at the wheel as those working during the day-time.  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.

Lowering Stress and Anxiety for Shift Workers (and for others too!)

Stress and anxiety are normal parts of life. Sometimes we all need a little angst to keep us going: to make the best presentation, ace the test, or get the job offer. But over time, the effects of too much tension can be mentally and physically taxing.

Extended periods of stress can cause destructive changes in the body, such as depression or a suppressed immune system, potentially leading to heart disease, stroke, or cancer. Stress and anxiety can be felt physically, appearing as an increased heart rate and high blood pressure, sweating, dry mouth, tight muscles, twitching, abdominal pain, and headaches. Emotional responses to stress may include feeling restless, being unable to concentrate, and talking negatively to yourself.

Shift workers experience unique challenges in their life and jobs that can lead to increased tension. Without proper planning, work/life/family balance can get completely out of synch as a result of working rotating shifts or long hours. As a result of the struggle to adapt to ever changing work schedules, shift workers often don’t get enough sleep.

While most sleep experts suggest seven to eight hours of sleep is needed to feel well-rested, most people don’t get this much, and shift workers get even less than the day time population. The National Institute of Health has reported that people who work at night or have frequent major shifts in their work hours, or who have inactive lifestyles, are at a greater risk of developing insomnia. Many shift workers also report that they don’t exercise frequently, so the problem only gets worse. Read this article…

Mental Health Conditions are on the Increase…and Shift Working Companies Should Take Notice

According to a report in the August 2009 issue of Archives of General Psychiatry, one of the JAMA/Archives journals, treatment for mental health conditions is becoming more common in the US. The article has several explanations for why this may be, including patient and medical providers having a broader understanding of the need for mental health treatment, recent significant outreach by nonprofit groups promoting mental health care, and the growing public acceptance of mental health treatments. A related outcome – antidepressants are now the most commonly prescribed class of medications in the US. Read this article…

Serotonin, the Happiness Holy Grail

Happiness has been an elusive goal ever since the beginning of humanity, but the idea that we can find happiness inside ourselves may be based on scientific fact. Serotonin is a chemical in our brains that strongly affects our mood, appetite, sleep, and sexual desire. Low levels of serotonin have been linked to depression, schizophrenia, and certain mental disorders, while normal and higher levels improve your mood and make you more relaxed. Many easy daily habits can increase your serotonin levels- take happiness into your own hands! Read this article…
