Shift Work and Worker Health: Beyond the Shift Work and Cancer Tie

Over twenty percent of the U.S. workforce holds jobs that the World Health Organization now considers possible causes of cancer. Most people who work extended hours, shifts, or nights have probably already seen the “Graveyard Shift Soon to Be Listed As ‘Probable’ Cause of Cancer” article, and gotten appropriately nervous. But, for the bad news before the good, shift work brings health risks that go far beyond the big threat of cancer. The good news is that shift work does not automatically cause cancer, of course, and many habits common among shift workers have long been known to increase the risk of cancer. So, certain lifestyle changes can quickly cause your risk of cancer, and other diseases and chronic problems, to plummet. Read this article…

Women and Sleep…Sleep Stress and Sleep Disturbances…Welcome to the Bedroom!

Kids and caffeine, stress and sleep apnea, menstruating giving way to menopause: women have a lot of unwanted guests in the bedroom when it comes to getting enough sleep. Studies have shown sleep makes a huge difference in concentration, memory, alertness, and even weight loss and happiness. Staying safe at work depends greatly on workers getting enough sleep. Over a quarter of shift workers report making mistakes from inattention several times a month, and almost half report having nodded off while driving to or from work. These tired mistakes can have sometimes fatal consequences. A healthy sleep schedule can save lives. Read this article…

Men and Sleep; Yes – Men have Challenges Too

Going for 22 hours without sleep is equivalent to having a blood alcohol level of 0.05. One is perfectly legal, but the other could cause you to be arrested for being behind the wheel and kicked out of work. Shift workers, especially night shift workers, might see nothing out of the ordinary in going 22 hours without sleep, but they pay for it with their health, and sometimes even with their lives. Exhaustion decreases alertness, attention and the ability to process new information, creating danger on the job. When working with machinery, as many shift workers do, or in health care of emergency services, one slip of attention can cause accidents, injury, and death. Bad sleep habits also set off a whole variety of health problems, including weight gain leading to obesity. Many existing issues, such as depression, asthma, and addiction to drugs or smoking can make sleep habits worse, and then continue to worsen themselves because of the troubled sleep. Sleeping pill prescriptions reached 56 million in 2008, showing the extent to which sleep problems haunt Americans. But this is a problem that can be conquered. Read this article…

The Impact of Fatigue on Driving

Most people know that driving after drinking enough alcohol could be a death wish, but driving home after a seemingly endless shift could be equally dangerous. After 22 hours without sleep, you act the same behind the wheel as if you had a blood alcohol level of 0.08, the legal driving limit. It won’t get you pulled over (yet, although several states have laws pending to outlaw driving while drowsy) but falling asleep at the wheel can send you hurtling towards a tree or another vehicle with no control over your car just as easily as alcohol or drugs can. The urge to reach home and bed can sometimes overtake caution on the road. Truck drivers and night-owl teens are also greatly affected by this risk, which often goes unnoticed in our up-and-at-’em culture. Read this article…

Linking Sleep Loss and Obesity

Results from a 2003-2004 National Health and Nutrition Examination Survey indicate that an estimated 66 percent of U.S. adults are either overweight or obese. The same survey indicates that an estimated 17 percent of children and adolescents ages 2-19 years are overweight.

Restless Legs Syndrome and Its Connection to Shift Work

For shift workers slumping into bed after a long night shift or extended hours work day, a pain that feels like a burning iron on your leg is not the feeling you were hoping for. Restless Leg Syndrome (RLS), a chronic problem sometimes unnoticed by health care, affects almost 10 percent of the population, yet it is still a misunderstood and often forgotten disorder. A shiftwork lifestyle causes workers to face a much greater risk for Restless Leg Syndrome than the normal population. Restless Leg Syndrome often goes undiagnosed for up to twenty years after it rears its ugly head, causing pain, lack of sleep, and irritation, but people can work their way towards recovery. It is important for shift workers to arm themselves with knowledge of RLS and its symptoms, so that they can avoid unnecessary harm. Read this article…

How Circadian Rhythms and Sleep Patterns Affect Learning and Performance

Circadian rhythms, or each person’s internal “body clock” that clicks through the day setting off urges to sleep, eat, and complete other daily actions, have a larger affect on our lives than one might realize. Every body has a definitive time of day in which it is most alert, least alert, most active and most tired, and screwing with this natural cycle can be disastrous. Shift work forces most people to work outside their natural, circadian determined working hours, like working nights or evenings, so that not only do workers find it more difficult to concentrate on their job while they are doing it, they also have more trouble relaxing and falling asleep during their off-hours. Your circadian biological clock can be “reset” over time using light therapy and gradually shifting sleep times to the desired pattern, but many shift workers try to sleep normal hours during their days off and opposite hours when they work night shifts, further disrupting their body clock. Several methods can help night workers and extended hours workers determine the workings of their own circadian rhythms and biological clock, and to better adapt themselves to shift work schedules.

Spring Cleaning: Understanding the Physiological Benefits of Daylight Savings Time

Benjamin Franklin first suggested the idea of Daylight Savings Time in 1784, long before electricity, when keeping the clock’s hours more in line with the sun was the only way to avoid more time working in the dark for farmers in the winter. The idea caught on after World War I, yet many people still wonder about Daylight Savings Time’s meaning and importance. While it’s annoying to lose that one hour of sleep in the spring as you move the clock forward, Daylight Savings Time helps us improve our health and mental state by allowing us more time in the sun, and saves us money on energy bills by making sure more of our active hours are lit by daylight.

When Fall Arrives: Preparing Children (and Parents) for Going Back to School

Any parent who has ever faced the Herculean struggle of trying to drag a teenager out of bed in the morning for school has felt the stress September brings. Most parents have probably wondered at one point or another why their teenager seems so drained all of a sudden. Now, science shows that Circadian rhythms, that determine when we feel hungry, tired, and experience other bodily urges on a daily basis, do in fact shift as we age. As we go through different stages of life, we not only need different amounts of sleep, our bodies need that sleep at different times. A teenager feels alert and ready to learn at different times than do younger siblings, parents, or older people. For parents that work nights or shifts, helping understand children’s sleep schedules when you’re busy worrying about your own can be tough. Adapting to age-specific schedules can help families be the most prepared to enter the school year with the least stress possible. Read this article…
