Protect Daytime Sleep Of Shiftworkers

Monday, December 15th, 2008

Labor statistics point to the fact that workers working “non-standard” hours account for approximately 25% of the labor force. This means that there are millions of people working weekends, evenings, nights and various shiftwork schedules. If you aren’t a shiftworker, you probably know someone who is.

We rely on shiftworkers to provide not only health and protective services, but a wide variety of services that we demand ’round-the-clock, at our convenience. Want pizza and a movie at 3 a.m., just call your local provider. Want to order a product or do your banking, just call a toll-free number or use the internet. Want your package in another city tomorrow morning, the courier will have it there.

But for all these services to be convenient and available, someone must be working at night - baking the pizza, answering the toll-free line, sorting the packages and flying them around the world. And if they are working at night, they will need to sleep in the daytime.

And, therein, lies the problem. We demand convenience and ’round-the-clock services, but have not yet recognized that we need to be mindful of the workers who need to sleep in the day as a result. We continue with our noisy and disturbing daytime activities with no consideration for the fact that our neighbor or friend may be trying to sleep. As a result, getting any sleep may be very difficult.

Sleep is also difficult in the daytime because, physiologically, our bodies were designed to sleep at night and work during the day. When we try to sleep during the day, our own body is working against us, trying to keep us awake.

Another factor serving to minimize the amount of sleep workers get is the belief that sleep is dispensible. If we short-change our sleep, it doesn’t matter. Yet more and more research is showing that even one disturbed sleep period or sleep loss has an impact on memory, learning and moods. On-going sleep deprivation leads to more serious consequences of illness, depression and perhaps even a shortened life span.

Sleep is not a luxury. It is essential to our well-being. As shiftworkers, we must be diligent in protecting our sleep and as a community we need to be more mindful of the need for daytime sleep for those who serve us at night.

Shiftwork Schedules

Monday, December 1st, 2008

“What’s the best shiftwork schedule?” The “best” shiftwork schedule is the one that best meets the needs for production, efficiency, safety and worker well-being. This means that schedules will, by design, be different for every workplace.

In spite of this, there are some principles that distinguish better schedules from others. For example, the best schedules are either long or short, that is, they have no more than 2 of any shift in a row or they have more than 14 of the same shift in a row. Intermediate shift rotations (4 - 7 of the same shift in a row) are universally considered to be the most stressful for workers.

Schedules that rotate forward (days - afternoons/evenings - nights) also contribute to worker well-being and usually result in production and safety improvements.

Schedules that allow for permanent shift assignments or established rotations are also favored. Casual/-on-call/swing shift assignments on an on-going basis make huge physical and emotional demands on workers.

Schedules that allow for frequent weekend and evening time for family and friends are also preferred by most workers. In lieu of this, schedules that provide at least four days off in a row are usually attractive to workers.

How good a schedule is is also a factor of management practice. For example, even less than perfect schedules can be tolerated by workers if they have the opportunity to self-schedule and trade-off as their personal needs require.

When you are designing your schedule, be creative. Keep all options open. You will find that you will discover schedule variations which you may not have considered previously and the schedule you decide on will be the best schedule for your workplace.

Food & Diet Strategies to Promote Sleep

Sunday, June 1st, 2008

Limit your consumption of caffeine, including coffee, cola, tea, chocolate milk. Consume no caffeine at least 4 hours before sleeping.

Limit the intake of liquids for the last 2 hours before the end of the night shift so that you have less need for elimination when you are wanting to sleep during the day.

Eat adequately so that hunger does not prevent you from sleeping.

Because proteins tend to promote alertness, you will want to avoid protein foods before sleep and have complex carbohydrate-type foods (whole wheat toast, oatmeal, etc.) to promote sleep.

Limit alcohol, especially before sleep. Alcohol usually induces sleep, but it reduces the quality of sleep.

Some specialists advocate a “fasting and feasting” strategy for readjusting sleeping and eating schedules. It works well for some people, but requires diligence and a good deal of attention to not only the food you eat, but what time it is consumed. If you want to know more about this strategy, you can review some of the literature about jet lag.

Shiftworkers have a greater incidence of GI and CV disease and illness

Shift workers generally have poorer lifestyle habits (smoke more, exercise less) which contribute to higher rates of cardiovascular disease. However, other factors associated with shift work also contribute to this situation. For instance, shift workers experience higher rates of stress and fatigue, particularly if their schedules do not reflect best practise. They also get less sleep on average than regular day workers and sleep deprivation is a major influence on the development of cardiovascular disease.

Some shift workers are more at risk than others. Our proprietary tools help to identify those at greater risk.

If you are a shift worker, you most likely have experienced some type of gastro-intestinal upset. You may be tired and ‘off-schedule’ and don’t feel like eating or make poor food choices. Most workplaces also do not provide healthy, if any, food choices, especially during the night. Do you know what healthy and convenient food choices are best for shift workers?
