Sleep, that often elusive (especially for shift workers) yet essential part of all of our lives, is in the news again because of a new study published in the journal Science last week.
Scientists at the University of Rochester have discovered that sleep, in addition to boosting learning and memory retention and helping us feel more rested and alert, also gives our brains the opportunity to ‘take out the trash’. The trash is the toxic byproducts of activity during the daytime that need to be flushed out. The brain’s cleaning system goes into high gear when we are asleep by shrinking the cells in the brain allowing the cerebrospinal fluid to circulate throughout the brain tissue collecting the waste and sending it into the bloodstream. From there it is carried to the liver for detoxification.
Dr. Charles Czeisler, chief of the division of sleep medicine at Brigham and Women’s Hospital, commented that the brain acts like a smart sanitation engineer; it’s easier to move the trash at night when the streets are clear. When we don’t get enough sleep or stay up all night, the toxins aren’t removed as efficiently as when we are sleeping. This explains why sleep deprivation has such strong and immediate consequences, such as mental fog and crankiness.
The results of this study are of great interest to Alzheimer’s researchers because one of the byproducts that is cleaned out daily is beta-amyloid, clumps of which form plaques found in the brains of Alzheimer’s patients.
If we didn’t already have enough reasons for trying to get enough sleep, this can certainly be added to our list!

Looking for a way to increase your physical activity and fit the recommended 150 minutes of exercise per week into your already full day? Start cleaning! As health experts look at the continued weight gain of people in North America, they have blamed fast food and sugary drinks. However, a recent study reports that one reason for the gain could be that we are doing half the housework than we did in the past.
The researchers report that currently 13 hours per week are spent doing housework, about half of what was done in 1965. They have calculated that 360 fewer calories are burned each day because of the decline in housework. This is the equivalent of 30 minutes of running or an hour long aerobics class seven days a week. Wow!
So pick up your broom, scrub that floor, wash your dishes, pick up the clutter, clean out that closet – get up and move! You will feel better, live longer, get in shape and have the cleanest house on the block!

The Centers for Disease Control and Prevention (CDC) recently reported good news with regard to walking-more Americans are doing it! The percentage of adults who went on a 10 minute walk once a week increased from 56% in 2005 to 62% in 2010. Even better is the fact that this increase was seen across all regions, races and ages.
We are certainly heading in the right direction, but we do have room for improvement. Federal guidelines recommend that adults get 2 ½ hours of moderate (brisk walking) to vigorous (running) exercise each week. It is not always easy to find the time to fit exercise into our routine; it is even more difficult for shift workers.
Walking is one of the most popular and accessible of physical activities since it requires no equipment, can be done anywhere and by people of different athletic abilities. How to start? Take the stairs instead of the elevator, park farther away, walk inside or outside your building when taking a break at work. Small steps can literally translate into lifesaving benefits.
Regular walking can improve your mood, lower blood pressure, help to manage diabetes and cholesterol and keep you trim and fit. Taking short breaks at work will keep you awake and at the top of your game. Give it a try!

As though there aren’t enough reasons to eat a healthy balanced diet, researchers have come up with one more-Vitamin B6. A study just published in the Journal of Nutrition shows a strong association between chronic inflammation and Vitamin B6; those people with the highest levels of B6 in their blood had the lowest levels of chronic inflammation and those with the lowest levels of B6 had the highest levels of chronic inflammation.
Normally, temporary inflammation, such as redness or swelling after an injury, is part of a healthy immune system. However, chronic inflammation is a much different and serious story. It occurs when the immune system does not shut off, which causes immune cells to interfere with the body’s healthy tissues. This can cause heart disease, diabetes and stroke, among other chronic diseases. Some of these are conditions that shift workers already have at a higher rate than day workers. Even scarier, most people don’t know they have chronic inflammation since there is not a reliable blood test to screen for it.
The findings from this study give researchers a better idea of what is going on in the body regarding this inflammation. Other studies are now being conducted to determine the exact role of Vitamin B6; at this time experts are not recommending supplements. However, they do recommend including foods in your diet that contain B6 as there are numerous other benefits of this vitamin. B6 is present in chicken breasts, fish, hamburger, legumes, pinto beans and vegetables like red peppers and potatoes. Shift workers should try to include these foods in their daily diet. They are all foods which provide numerous health benefits….enjoy!

Social media is proving to be an important tool for employers trying to encourage their employees to participate in Wellness Programs or to achieve weight/health goals. With much of the population looking at text messages, Facebook and Twitter each day, it appears to be the wave of the future.
The question at this point is how it should be used; many companies are coming up with ways it can be the most effective for their employees. Chilton Hospital in New Jersey had tried for years to engage its employees in programs and initiatives aimed at promoting well-being and reducing health care costs. The resulting behavior changes were minor and covered only a small number of employees. Then in 2011, Chilton tried a new approach; they entered a county-wide 100 day fitness challenge where employees from local companies formed teams of 6 and vied to see who could walk the most, lose the most weight and eat the healthiest. Participants logged onto a Facebook-like social network where they reported results and cheered each other on. As an incentive to participate, Chilton did offer a cash reward of $150 each to members of the winning team and $500 to the person who lost the most weight. Ultimately though, money was not the driving force; it was the challenge and online camaraderie that pulled people in.
Another company, incentalHEALTH, surveyed the participants in its own Wellness Program about their use of social media. It found that 90% of them were on Facebook and 81% texted daily. With this information, the company created a “push” model which delivers wellness information via daily coaching texts and a Brag to Facebook feature. Other features being considered are online wellness journals, discussion groups and progress reports that can be shared with others.
There is an ever growing list of services and apps now available (with more and more coming out each day) for those companies interested in promoting wellness through social media. What better way to get people involved and to change unhealthy behaviors than by employing a media that is an integral part of so many their lives?

Coronary heart disease is the result of plaque buildup in the arteries, which blocks blood flow and heightens the risk for heart attack and stroke. It accounts for 1 in 6 deaths in the United States.
Currently, the Framingham Risk Score is the most widely used method for measuring heart risk. It takes into account general information, such as blood pressure, cholesterol level and basic knowledge about whether a family member had a history of heart disease. Based on the results, a decision is made as to who may be at high risk.
However, a recent article in the Wall Street Journal reports that a new study shows that detailed family information could help doctors better predict who is at high risk for heart disease. Dr. Donna Arnett, a genetic epidemiologist and president-elect of the American Heart Association, says that, “Family history remains one of the most important predictors of an event for an individual. But “most of the family history that we’re collecting is just the presence or the absence of heart disease, not the age of onset or the type of disease.”
Another risk-measurement tool, the Reynolds Risk Score, does consider if a patient’s parent had a heart attack and at what age. This tool has been available since 2007 but is not yet widely used. Gathering the additional information does take more time and often, the patient is not aware of his family health history.
So the next time you are at a family gathering, ask some questions about the health histories of your parents, grandparents and siblings. Find out if they had heart disease, a heart attack and at what age. The more information you have, the easier it will be for your doctor to make a diagnosis. It could save your life!

Do you really know when you are sleepy…too sleepy to drive or perform an activity? This question is front and center as people are getting fewer hours of sleep each night than ever before. Studies show that consistently getting too little sleep poses long term health risks, but do a few nights of little sleep have any impact?
A recent article in the Wall Street Journal details the steps being taken by sleep researchers around the world to develop a test for sleepiness. They are trying to find ways to identify sleepiness in people before they are so impaired that accidents occur. We know that people who are sleepy have decreased attention, slower reaction times and problems learning and processing information. Many people often don’t know how sleepy they are until it is too late. This is especially significant for shift workers who generally get less sleep than day workers.
Some interesting information noted in the article are the results of a 1997 study published in the journal Nature which showed that being awake for 24 hours resulted in the equivalent level of cognitive impairment as having a blood-alcohol concentration of 0.1%. In the U.S., it is illegal for adults to drive with a concentration of .08% or above.
The WSJ reports that researchers are looking for a biomarker, a characteristic or substance, in the body that will indicate if someone is sleepy and if they are, just how sleepy. While actual biological tests are years away, great strides are being made.
Other ways of identifying sleepiness are also being pursued. A professor of applied physics in Finland, Edward Haeggstrom, has noted that balance is impacted by sleepiness; “the longer you have been awake, the more you sway”. Additional research notes the link between sleepiness and eye blinks; the sleepier you are, the slower your eyelids close.
While we know the importance and value of sleep, this research provides the hope that this new information and knowledge can be used in our daily lives as part of our health care regimen, helping us to lead healthier and safer lives.

Researchers come up with all kinds of crazy studies….all in the spirit of solving complex medical and scientific challenges that expand our knowledge and can potentially lead to curing disease. Sometimes however, all the research in the world seems to only take us back to what we already know. A recent study by psychologists at University of California – Berkley found that performance on learning and memory tasks are compromised by jet lag. The impact of jet lag has been closely correlated with the consequences of working shifts in research on the body’s circadian rhythms. But, learning and and memory problems can be avoided…..

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.

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…..

Shift workers are at greater risk for cardiovascular disease and diabetes as they themselves report getting less exercise and being prone to eating more unhealthy foods, especially when working nights. As a result, they are often overweight, contributing to heart disease and diabetes. But, small steps can make a big difference. The results from three new studies, all promoting the benefits of eating red foods [and drinks], have been released in the past few weeks. Read this article…

The National Sleep Foundation (NSF) has just released the 1st poll to examine sleep among four ethnic groups in the United States: Asians, Blacks/African Americans, Hispanics and Whites-the 2010 Sleep in America Poll. Although significant differences in the sleep habits and attitudes of each group are revealed, there are also a number of interesting similarities. The poll found that more than three fourths of respondents from each ethnic group agree that poor sleep is associated with health problems. It also showed that each group reports similar experiences missing work or family functions because of fatigue. This is of extreme significance to shift workers who routinely average less sleep than day workers.
The NSF is committed to understanding people’s sleep needs and giving them the tools necessary to get the optimum amount of rest. Read more about the poll and its findings at the NSF’s website…

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.

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.

Long nights, little sleep, changing shifts- the collision of stress and exhaustion can cause other types of collisions for shift workers, such as collisions between cars with tired drivers, collisions in the arteries that cause heart attacks and strokes, and a whole host of other worries. Night work and shift jobs cause a huge variety of health problems for shift workers, problems that can rip chunks out of struggling checking accounts. Rising health care costs become a concern for managers, who have to shoulder a good deal of the cost with insurance, and for workers, who not only have to deal with their illness or injury but with the stress of paying for it. No one wants to choose between their salary and their health, or their job and their life. Management needs to spend money efficiently to keep everyone going strong. Zeroing in on extended hours workers will provide an employer more bang for their health care buck. Read this article…
