Employee Health and Shift Work Lifestyle Training Leads to a Happier and Healthier Workforce….and to Increased Company Profits!

Is employee morale low at your company? Employee morale is higher when companies provide shift work lifestyle training.  Nearly 60% of employees at companies providing shift work lifestyle training rank their morale as good or excellent compared 35% without shift work training.[i] 

Some shift workers are at a greater risk for cardiovascular disease.  Want to save upwards of $6,500 for each of these at-risk employees per year?  And, protect your employees from this number one killer!

Workers in shift work operations generate, on average, more health care costs than other workers.  How about reducing overall company health care costs by 17% to 37% by targeting this population and helping them improve their health?[ii] Other cost savings may also be possible, including safety incident and workers’ compensation costs. Worker productivity may increase, possibly even up by 39%.[iii]

In extended 24-hour operations, a well-designed shift schedule or roster is unlikely to provide adequate protection from worker fatigue.  An integrated risk management system incorporates data analysis and training towards an effort of reducing fatigue and reducing a company’s costs, risks, and liabilities.[iv]

Among the shift worker population, 71% of men and 53% of women are overweight, 54% of workers have smoked or currently smoke, only 27.5% workers report having good nutritional practices, and 77% report not exercising regularly.  Add to this the sleep deprivation statistics, 27% of shift workers report making mistakes of inattention several times per month, and it’s clear that both shift workers and their employers would benefit from worker health and lifestyle training.[v]  In addition, a fatigue management program would help target the reasons shift workers aren’t always as attentive and productive as day-time workers and help companies and employees develop some initiatives to reduce employee fatigue levels. 

Each of the examples above show the overwhelming benefits to a company and its employees when an employee health and shift work lifestyle training program tailored to the company’s needs is implemented……..It’s all in the details, so read on for more information about targeting a program for your operation…..

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.

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.

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?

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?

Shift Worker Liquid Intake Extremely Important!

Most shift workers admit they don’t have the best understanding of nutrition and that they find it challenging to follow good nutritional habits. It makes sense that sticking with good nutritional meals can be difficult when working shifts – most shift workers admit they eat what they can find with the least effort – which is often food from vending machines, 24/7 convenience stores, or fast food restaurants. What doesn’t make sense is that shift workers don’t have better knowledge about their own nutrition. Certainly with education, just as with everyone, shift workers’ nutritional awareness can be exponentially increased.

We often read about nutrition and relate it immediately to the food we eat. We’ve written in other posts about the importance of eating healthy food – see “Be Careful What you Eat When Working Shift Work.” However, liquid sustenance is a significant part of our daily intake as well. When we’re awake, we drink water, juice, soda, coffee, tea, alcoholic beverages, and some of us drink liquid nutritional supplements too. What’s important about the liquids we put in our body? The essential information to know is about hydration and dehydration, calories and caloric content, and how where you live, the job you perform and your overall activity level impacts your body’s need for liquids.

Another Important Reason to Assess Levels of Vitamin D

Cardiovascular disease is the leading cause of death among those with diabetes. And, according to researchers at the Washington University School of Medicine in St. Louis, people with diabetes and low Vitamin D have more than double the risk of cardiovascular disease. One possible reason (according to the study’s authors) – diabetics who are deficient in vitamin D don’t process cholesterol normally, so it builds up in their blood vessels and increases the risk of heart attack and stroke. Why is this important to shift workers? Because some studies have shown that shift workers may have a greater risk of developing type 2 diabetes and shift workers are also are at a greater risk of having a vitamin D deficiency. This study may provide more support for why shift workers have a greater likelihood of suffering from cardiovascular disease. And, it also sheds some light on a possible way to reduce the risk of heart disease – besides exercise, good nutrition, and maintaining proper weight, make sure you get enough vitamin D.

Feeling the Impacts of Chronic Stress Brings You Back to Old Habits

Do you feel frazzled and overwhelmed? Are you having trouble sleeping? Are you anxious and impatient? These are just some of the symptoms of chronic stress. According to a new study, the effects of chronic stress force us back into old habits. And this may actually cause us to make bad decisions because in some situations, we are better off inhibiting a habit and instead using a goal oriented strategy – an effort that will force us to approach the situation differently. But when we are stressed we are more likely to just fall back on our habitual approach to dealing with the situation as opposed to being creative and forging a new path.

Untreated Sleep Apnea Outcomes Continue to be More and More Severe

Since shift workers are more likely to suffer from sleep disorders than day time workers, these workers and their family members, employers, insurance providers, and medical practitioners should be especially knowledgeable about the various types of sleep disorders. And, they should stay on top of new information that is released about chronic sleep issues that may impact them. Sleeping is fun – just think of all those wonderful dreams. Not dreaming, maybe you have a sleep disorder. Read here for information on sleep apnea. See other parts of our blog for insomnia, restless leg syndrome and other disorders.

Slowing Down the Aging Process – Tips for Shift Workers

Life expectancy has been increasing year after year in many countries, including the U.S. However the U.S. ranks 42nd in life expectancy but number one in health care costs per capita. Clearly this has gotten the attention of the Obama administration. Question is whether this significant issue will be solved by focusing more on health care prevention, limiting access to care once chronic health issues are diagnosed, by better managing how diagnoses are determined or by all of these things. Shift workers have unique challenges that need to be managed proactively by workers, employers, insurance companies, and medical practitioners.

Shiftworkers, Take a Deep Breath- Reducing the Risk of Lung Disease

On a normal day, we breathe nearly 25,000 times; the air we breathe in contains mostly oxygen and nitrogen. But air also has things in it that can hurt our lungs; bacteria, viruses, tobacco smoke, car exhaust, and other pollutants can be in the air. People with lung disease have difficulty breathing. These breathing problems may even prevent the body from getting enough oxygen.

A low oxygen level puts excess stress on the entire body, but especially on the heart. When oxygen levels are low, pressures inside the heart increase; the heart muscle becomes enlarged and does not pump as it should, resulting in heart failure. It has been well documented that degenerative diseases, including cancer and premature aging, start with low oxygen levels in the body. Also, as we age, we lose vital capacity and the ability to effectively obtain adequate oxygen. After age 25 we lose 10% lung (respiratory) capacity every 10 years, due to shallow breathing.

Lung disease is responsible for one in seven deaths in the United States each year. More than 35 million Americans are living with chronic lung disease including asthma, emphysema and chronic bronchitis. Other diseases impacting the lung include lung cancer, tuberculosis, pneumonia, HIV/AIDS, pulmonary fibrosis and sarcoidosis (inflammation producing tiny lumps of cells in various organs, including the lungs), and influenza. Lung disease and breathing problems are the number one killer of babies younger than one year old. Read this article…

Weight, Obesity, Fitness and Health

With shift work, weight gain seems almost unavoidable- perhaps even more reliable than a weekly paycheck. Behind us are our genes, programmed in times of hunting and gathering to push us to see food, grab it, and devour it, since who knows when another fruit tree or dead animal fall into our laps? In front of us living in the 21st century is McDonalds, Dairy Queen, Sonic, Burger King, huge supermarkets, big plates and silverware, lattes, breakfast muffins, cars to carry us from one place of food to another. Furthermore, shift work makes time for exercise difficult. Night shifts sleep, which can cause the body to hang on to extra weight. It’s no wonder obesity has become such a problem. Many news articles talk about the problem, but how can you determine your risk level and what plan of action is right for you? Read this article…

Vitamin D Deficiency Updated

When a diet lacking in proper nutrients collides with a job that rarely lets you see the sun, vitamin D deficiency can rear its ugly head. Too much time in the sun of course can cause sunburns and raise the risk of skin cancer, but too little and the risk of heart disease skyrockets. Spending some relaxing time out in the sun and eating vitamin-D rich foods such as eggs can work wonders. Read this article…
