One-Third Of U.S. Workers Aren’t Getting Enough Sleep: Study, Tampa

Despite the recommendation that adults get between seven and nine hours of sleep a night, a new study shows that about a third of us aren’t hitting those goals.

Researchers from the Centers for Disease Control and Prevention looked at data from the 2010 National Health Interview Survey on sleep habits of U.S. workers. They found that 30 percent of people in the study — which calculates to about 40.6 million workers in the U.S. — get fewer than six hours of sleep a night. Their research was published in this week’s Morbidity and Mortality Weekly Report.

The study of 15,214 people also shed light on what kinds of jobs are linked with less sleep. The researchers found that people who work in manufacturing get less sleep than other workers, with 34.1 percent of them reporting getting less than six hours of sleep a night.

In addition, people who work the night shift were more likely to report getting inadequate sleep (44 percent), compared with those working during the day (28.8 percent).

Among people who worked the night shift, certain industries had high prevalences of inadequate sleep, including 69.7 percent of warehouse and transportation workers and 52.3 percent of health-care and social assistance workers, according to the report.

The researchers also found that people between ages 30 and 64 were more likely to report not getting enough sleep, compared with workers between ages 18 and 29 and workers age 65 and older.

People who work more than one job are also more likely to not get enough sleep during the night, compared with people who just have one job — 37 percent versus 29.4 percent. People who work more than 40 hours a week are also less likely to get enough sleep per night, compared with those who work a 40-or-under week.

Sleep deprivation is dangerous because it raises the risk of a whole host of health problems. Studies have linked inadequate rest with depression, a decreased immune system and memory issues, WebMD reported. Sleep deprivation has also been linked to obesity, high blood pressure and daytime fatigue, which could present safety issues on the job, Harvard Medical School reported.

Is There A Link Between Sleep Problems And Fibromyalgia Pain? Tampa

People with fibromyalgia often report problems with sleeping, but a new study in the Journal of Pain shows that troubled sleep doesn’t actually predict fibromyalgia pain.

University of Florida researchers hypothesized that because past research has shown a link between troubled sleep and other kinds of pain, as well as a link between sleep deprivation and pain in people who don’t have fibromyalgia, there might be a link between less sleep and pain from fibromyalgia.

But in their study, they found that lack of sleep was not able to predict the pain the study participants felt. Their study was based on 74 people with fibromyalgia, whose sleep and pain information was taken for 14 days.

“This study suggests that measures of sleep duration and nightly wake time do not predict fibromyalgia pain at the group level,” the researchers wrote in the study. Rather, they said that being inactive or having fatigue may better predict pain than the amount of sleep obtained in a night.

However, this research isn’t to say there’s no link between sleep and fibromyalgia. A recent study in the journal Arthritis & Rheumatism showed that trouble sleeping can increase a woman’s risk of developing fibromyalgia by more than three times, compared to people who get better rest, Health.com reported.

But still, the researchers of that study cautioned that the research doesn’t show that sleep problems cause fibromyalgia, Health.com reported:

“Sleep problems are just one factor that may contribute to the development of fibromyalgia,” says Paul J. Mork, Ph.D., a study coauthor and a researcher at the Norwegian University of Science and Technology, in Trondheim. “Fibromyalgia is a complex pain syndrome and there are numerous other factors that may contribute to the development of this illness.”

Depression linked with sleep breathing problems, study finds- Tampa

Experiencing breathing problems during sleep may raise your risk of  depression, a new study suggests.

Women with sleep  apnea, in which breathing becomes shallow or pauses briefly during sleep,  were 5.2 times as likely to have depression compared with women without the  condition. Men with sleep apnea were 2.4 times as likely to have depression as  men without the condition, according to the study from researchers at the Centers  for Disease Control and Prevention (CDC).

Participants in the study who had other breathing  problems during sleep also  had an increased risk of depression. However, the researchers found no increased  likelihood of depression among people who snore.

“Snorting, gasping or stopping breathing while asleep was associated with  nearly all depression symptoms, including feeling hopeless and feeling like a  failure,” said study researcher Anne Wheaton, an epidemiologist with the CDC.  “We expected persons with sleep-disordered breathing to report trouble sleeping  or sleeping too much, or feeling tired and having little energy, but not the  other symptoms.”

Both depression and breathing problems during sleep  are common, and both are underdiagnosed, the researchers wrote. Screening people  who have for one disorder for the other could lead to better diagnosis and  treatments, they said.

The researchers took into account other factors that might influence the  results, such as age, sex and weight. The results are in line with those of the  other studies, the researchers said.

The study found an association, not a cause-and-effect link. However, the  researchers wrote that evidence from other research suggests that breathing  problems during sleep may contribute to the development  of depression. For example, one previous study found a link between the  severity of breathing problems during sleep and the odds of later developing  depression. And other studies have shown that people who received treatment for  sleep apnea showed improvement in their depression.

“Mental health professionals often ask about certain sleep problems, such as  unrefreshing sleep and insomnia, but likely do not realize that [breathing  problems during sleep] may have an impact on their patients’ mental health,” the  researchers wrote in their conclusion.

Although exactly how the link might work is unclear, it could partly be  explained by the fact that people with breathing problems experience sleep  that is fragmented, or may have low levels of oxygen in the blood during  sleep.

The researchers used data collected from 9,714 adults who participated in the  National Health and Nutrition Examination Survey, which is an ongoing study  conducted by the CDC.

Participants were considered to have depression based on their answers to a  questionnaire asking about how often they experienced symptoms of  depression.

Six percent of men and 3 percent of women in the study reported having  physician-diagnosed sleep apnea.

The study was limited in that participants’ depression and sleep problems  were measured at only one point in time, and in that it relied on self-reported  symptoms. People may not be aware they have breathing problems during sleep, and  there was no information about whether participants were being treated for  depression.

The study is published in the April issue of the journal Sleep.
