Insomnia may not just take a toll on your health -- it could also cost a lot of money.
New research published in the journal Archives of General Psychiatry shows that insomnia is linked with as many as 274,000 errors and accidents in the workplace each year, costing $31.1 billion in total.
"Accidents and errors directly affect the corporate bottom line," study researcher Victoria Shahly, of Harvard Medical School, told HealthDay.
For the study, more than 10,000 people were surveyed as part of the America Insomnia Survey, the Los Angeles Times reported. HealthDay reported that insomnia of at least a year-long period affected 20 percent of the study participants.
Participants were asked about any accidents in the workplace "that either caused damage or work disruption with a value of $500 or more" or "that cost your company $500 or more," according to the study.
Researchers found that workplaces mistakes related to insomnia were more costly than other kinds of errors, with insomnia-related errors costing $32,062 compared with non insomnia-related errors costing $21,914, on average.
Plus, they found that 7.2 percent of workplace errors were linked with insomnia, as well as 23.7 percent of costs incurred because of these errors, according to the study.
HealthDay pointed out that there may be other factors also at play that could contribute to these costs, but the study still shows a definite link between insomnia and these costly workplace errors.
Last year, a study in the journal SLEEP showed that insomnia costs the nation a total of $63.2 billion and 252.7 days in lost productivity each year.
Having trouble sleeping yourself? Check out these natural remedies for insomnia, from Michael Decker, Ph.D., an associate professor at Georgia State University and spokesperson for the American Academy of Sleep Medicine:
Soothing music before bedtime can really do the trick. A 2005 study found that older people who listened to 45 minutes of soft tunes before hitting the hay reported a <a href="http://www.blackwellpublishing.com/nursing/news/news.asp?id=124" target="_hplink">35 percent improvement in their sleep problems</a>. But it doesn't have to be Brahms, if that's not your style. As long as the music was soft and slow -- around 60 to 80 beats per minute -- it can spur <a href="http://news.bbc.co.uk/2/hi/health/4228707.stm" target="_hplink">physical changes known to promote sleep</a>, like a slower heart rate and breathing, the BBC reported. "We know that when a person closes their eyes they induce a certain frequency of brain waves," says Decker. Slow music may have a similar effect, he surmises, leading to sleep onset. <em>Flickr photo by <a href="http://www.flickr.com/photos/llimaorosa/112246369/" target="_hplink">Llima</a></em>
It was once thought that a glass of warm milk at bedtime would help send you off to dreamland because of the tryptophan, <em>The New York Times</em> reported, but milk and other protein-rich foods actually <a href="http://www.nytimes.com/2007/09/04/health/04real.html" target="_hplink">block tryptophan's sleepiness-inducing effects</a>. However, there might still be a psychological benefit to that warm milk, the <em>Times</em> concluded, calling it "as soothing as a favorite old blanket." "There have been some studies showing that when infants receive warm milk before bed, they'll dream a little bit more," says Decker, but the results don't hold true in adults. "It may be one of those myths that because it happens in children, adults think it may be true for them, too," he explains. However, many adults are actually at least slightly lactose intolerant, he says, meaning a warm mlik at bedtime may just lead to discomfort. <em>Flickr photo by <a href="http://www.flickr.com/photos/julianrod/152930252/" target="_hplink">julianrod</a></em>
If your goal is to bore yourself to sleep, you might try counting sheep, or counting backwards by multiples of three or any of a number of other counting-related mind-numbers. But a 2002 study found that <a href="http://www.ncbi.nlm.nih.gov/pubmed/11863237" target="_hplink">imagining a more relaxing scene might be more effective</a>. The study observed 41 people with insomnia over a number of nights and asked them to try a variety of different sleep-inducing techniques, like counting sheep. On the nights they were told to imagine relaxing scenes like a beach, a massage or a walk in the woods, <a href="http://www.mentalfloss.com/blogs/archives/53137" target="_hplink">they fell asleep an average of 20 minutes sooner</a> than on the nights they were told to count sheep or were given no instructions, Mental Floss reported. Decker agrees. "Counting sheep in and of itself may not help," but can act as a ritual that prepares us for sleep, making it not unlike meditation. Counting sheep -- or more relaxing guided imagery -- helps us "focus on something other than life's stressors," he says. "Thinking about a soothing environment may be more restful than the way you spent the last eight hours!" <em>Flickr photo by <a href="http://www.flickr.com/photos/narciss/3716241331/" target="_hplink">Kr.

Focusing on the breath, whether it's as part of a pre-bed yoga sequence or just a tuned-in awareness, can also have meditation-like effects in preparing for bed, says Decker, like lowering the heart rate. <em>Flickr photo by <a href="http://www.flickr.com/photos/perfectoinsecto/2363255713/" target="_hplink">Perfecto Insecto</a></em>
Your body temp <a href="http://www.health.com/health/condition-article/0,,20189095,00.html" target="_hplink">dips about two hours before bedtime</a>, <em>Health </em>magazine reported, a natural change that "triggers our brain for sleep onset", says Decker. Soaking in a warm bath beforehand boosts your temperature temporarily, but results in a dramatic, rapid cooldown after you get out that relaxes you and eases you into sleep. It's not necessarily the bath that lulls you to sleep, it's that resulting cooling of your body temperature, Decker emphasizes. Research shows that people who take a warm bath before bed not only <a href="http://www.ncbi.nlm.nih.gov/pubmed/2578367" target="_hplink">fall asleep more quickly</a>, but also report better quality of sleep, he says.
Many people swear by a drink to unwind at the end of the day, but alcohol before bed can actually <a href="http://www.huffingtonpost.com/2012/07/04/fourth-of-july-sleep_n_1644627.html#slide=1176662" target="_hplink">disrupt your sleep</a>. You'll be more likely to wake up more often in the early-morning hours, wake up and not be to fall back to sleep or have disturbing dreams. "As alcohol is metabolized by the liver, it has a disruptive effect," says Decker. It takes a few hours to metabolize, he says, so a drink with dinner shouldn't be a problem, but anything too close to bedtime can be counterproductive. <em>Flickr photo by <a href="http://www.flickr.com/photos/rob-qld/2889139445/" target="_hplink">Rob Qld</a></em>
Get Out Of Bed
It sounds crazy -- how will you ever get to sleep if you're not even in bed?! -- but it works, says Decker. "When a person stays in bed and they can't sleep, the bedroom can induce a certain level of anxiety," he says. "We say after 15 or 20 minutes, get out of bed, sit in another part of the house until you feel a little groggy, then go back to sleep," he says. "Staying in bed can condition you to become anxious in bed." A small 2011 study published in the <em>Archives of Internal Medicine</em> found that among the <a href="http://healthland.time.com/2011/01/27/cant-sleep-it-may-help-to-get-out-of-bed/" target="_hplink">adults studied who reported trouble sleeping</a>, those who spent <a href="http://www.thirdage.com/news/insomnia-cant-sleep-get-out-bed_1-26-2011 " target="_hplink">less time in bed had better sleeping habits</a>. <em>Flickr photo by <a href="http://www.flickr.com/photos/perfectoinsecto/3948115802/" target="_hplink">Perfecto Insecto</a></em>
