Insomnia raises risk of fatal injury

Having insomnia can raise a person's risk of death by motor vehicle and other fatal injuries.

New research suggests that insomnia is a major contributor to deaths caused by motor vehicle crashes and other unintentional fatal injuries. The results underscore the importance of the "Sleep Well, Be Well" campaign of the National Healthy Sleep Awareness Project.

Results show that the risk of unintentional fatal injury increased in a dose-dependent manner with the number of insomnia symptoms present. People with all three symptoms of insomnia were 2.8 times more likely to die from a fatal injury than those with no insomnia symptoms, even after adjusting for potential confounders such as alcohol consumption and daily use of sleep medication.

Among the three insomnia symptoms, difficulty falling asleep appeared to have the strongest and most robust association with fatal injuries. People who almost always had difficulty falling asleep were more than two times more likely to die from a motor vehicle injury (hazard ratio = 2.40) and more than 1.5 times more likely to die from any fatal injury (HR = 1.66) than people who never had trouble initiating sleep. Further analysis found that self-reported difficulty falling asleep contributed to 34 percent of motor vehicle deaths and eight percent of all unintentional fatal injuries, which could have been prevented in the absence of insomnia.

"Our results suggest that a large proportion of unintentional fatal injuries and fatal motor vehicle injuries could have been prevented in the absence of insomnia," said lead author Lars Laugsand, MD, PhD, postdoctoral fellow in the department of public health at the Norwegian University of Science in Technology in Trondheim, Norway. "Increasing public health awareness about insomnia and identifying and treating people with insomnia may be important in preventing unintentional fatal injuries."

The study results are published in the November issue of the journal Sleep.

"Healthy sleep is essential for physical health, mental well-being, and personal and public safety," said American Academy of Sleep Medicine President Dr. Timothy Morgenthaler, a national spokesperson for the Healthy Sleep Project. "Sleep is a necessity, not a luxury, and the promotion of healthy sleep should be a fundamental public health priority."

Earlier this year the Healthy Sleep Project launched the "Sleep Well, Be Well" campaign to increase awareness of the importance of sleep as one of the three pillars of a healthy lifestyle. More details are available at http://www.projecthealthysleep.org.

The study involved that analysis of population-based survey data from 54,399 men and women between 20 and 89 years of age. Cause of death was identified using a national registry. During the 13-year follow-up period there were 277 unintentional fatal injuries, including 169 deaths from falls and 57 deaths from motor vehicle crashes.

According to the Centers for Disease Control and Prevention, there are more than 126,000 unintentional injury deaths in the U.S. each year, making it the fifth leading cause of death. There are more than 33,000 motor vehicle traffic fatalities and more than 27,000 unintentional fall deaths annually, as well as 29.3 million emergency department visits related to unintentional injuries.

The danger of overlooking insomnia

The article details how important it is to get insomnia symptoms checked by a doctor, and discusses what health outcomes could occur from not doing so.

With our busy lives, it can be tempting to shrug off—or ignore altogether—difficulties with sleep. Trouble falling asleep, difficulty staying asleep throughout the night, waking feeling tired and unrefreshed: these are commonly experienced disruptions to sleep for millions of adults. Too often, these sleep problems aren’t taken seriously, or are considered the less-than-ideal price to pay for living full and sometimes hectic lives.

Difficulty falling asleep, waking during the night, waking very early in the morning, and experiencing un-restorative sleep are all symptoms of insomnia, a serious sleep disorder. People may experience these symptoms all at once, or some of them and not others. They may experience them chronically or every so often. They are signs of disrupted, poor quality sleep and they should never be ignored.

New research indicates how high a price we may pay for overlooking signs of insomnia. Scientists at Massachusetts’ Brigham & Women’s Hospital have identified a link between insomnia symptoms and elevated risk of death. Their study, which included more than 23,000 men, found certain symptoms of insomnia associated with higher mortality risk from cardiovascular disease. The men were all participants in the Health Professionals’ Follow-Up Study, a long-term, ongoing research endeavor that investigates issues related to men’s health. In 2004, 23,447 men reported to researchers about their sleep and any insomnia symptoms. Researchers followed up with the men over a period of 6 years, during which time 2,025 of the men died. After adjusting for other mortality-influencing factors including age, lifestyle habits, and other health problems, researchers analyzed data on men’s mortality as related to the presence of the following insomnia symptoms:

• Trouble falling asleep
• Difficulty maintaining sleep
• Waking in the early morning
• Experiencing non-restorative sleep

They found that several symptoms of insomnia were associated with higher rates of cardiovascular death among the men. In particular:

• Men who reported having difficulty falling asleep had a 55% increased risk of death from cardiovascular disease as compared to those men who did not experience this sleep difficulty.
• Men who reported experiencing un-refreshing sleep most of the time were at 32% higher risk for cardiovascular death than men who did not report this symptom.

Poor sleep is well understood to have a serious, negative impact on heart health. Not sleeping well, or enough, raises the risks for a number of cardiovascular problems, including high blood pressure, heart attack, heart failure, and stroke. Protecting the quality of sleep as we age is a critical component of protecting long-term cardiovascular health.

This isn’t the first scientific evidence of a link between poor sleep and increased mortality risk. But the news is particularly worrisome because these symptoms are quite common, particularly as we age. Estimates suggest that 30% or more of American adults experience some insomnia symptoms at least periodically, and for 10-15%, insomnia is chronic. Insomnia grows increasingly common with age: more than half of adults over the age of 65 experience symptoms of insomnia. Women are at higher risk than men for insomnia, due in part to hormonal cycles during childbearing years and to the hormonal changes associated with menopause. This current study included only men, but other research has shown higher risks of mortality associated with poor sleep in both men and women:

• In a number of studies that included both men and women, sleeping fewer than 6 hours and more than 8 hours per night has been associated with increased mortality risk.

• Obstructive sleep apnea in men and in women is linked to significantly highercardiovascular and overall mortality risks. Studies have shown that mortality risks from cardiovascular problems are 2 or more times greater for adults with obstructive sleep apnea. The more severe the obstructive sleep apnea, the greater the mortality risks.

• Research has also linked use of sleeping pills to increased mortality risk. The link between higher rates of mortality and sleeping pill use exists even after factoring out other possible contributors to death risk, including health problems, age, and gender.

Ready for some good news? While sleep problems left untreated may shorten longevity, improving sleep can have powerful positive health benefits. A study conducted recently in the Netherlands found that a regular routine of 7-8 hours of sleep may have as significant an impact on risk for cardiovascular death as not smoking.Regular, sufficient amounts of high-quality sleep have also been linked to reduced riskfor type 2 diabetes, largely because of the positive effect that sleep can have on improving insulin sensitivity.

If you have symptoms of insomnia, don’t ignore them. Share them with your doctor. Make an honest assessment of your sleep habits and make a commitment to taking simple steps to improve your sleep routine and your overall sleep hygiene. Taking steps to improve the quality and quantity of your sleep is one important way to protect your cardiovascular and overall health for the duration of your life. And sleeping well may actually help you extend that duration.

Insomnia symptoms can raise risk of death

Both insomnia, and the symptoms of insomnia such as issues falling asleep or staying asleep, have been shown to risk a person's risk of death.

Insomnia increases risk of death

A study finds a link between insomnia and increased mortality risk.

Insomnia, the most common sleep disorder, affects up to one-third of the population in the United States. In new findings, researchers from Brigham and Women's Hospital (BWH) have found that some insomnia symptoms are associated with an increased risk of mortality in men. These findings are published online in Circulation and will appear in an upcoming print issue.

"Insomnia is a common health issue, particularly in older adults, but the link between this common sleep disorder and its impact on the risk of death has been unclear," said Yanping Li, PhD, a research fellow in the Channing Division of Network Medicine at BWH and lead author of the paper. "Our research shows that among men who experience specific symptoms of insomnia, there is a modest increase risk in death from cardiovascular-related issues."

Specifically, researchers report that difficulty falling sleep and non-restorative sleep were both associated with a higher risk of mortality, particularly mortality related to cardiovascular disease.

Researchers followed more than 23,000 men in the Health Professionals Follow-Up Study who self-reported insomnia symptoms for a period of six years. Beginning in 2004 through 2010, researchers documented 2025 deaths using information from government and family sources. After adjusting for lifestyle factors, age and other chronic conditions, researchers found that men who reported difficulty initiating sleep and non-restorative sleep had a 55 percent and 32 percent increased risk of CVD-related mortality over the six year follow up, respectively, when compared to men who did not report these insomnia-related symptoms.

"We know that sleep is important for cardiovascular health and many studies have linked poor or insufficient sleep with increased risk factors for cardiovascular-related diseases," said Xiang Gao, MD, PhD, a researcher in the Channing Division of Network Medicine at BWH and Harvard School of Public Health and senior author of this study. "Now we know that not only can poor sleep impact disease risk, but it may also impact our longevity. While further research is necessary to confirm these findings, there is overwhelming evidence that practicing good sleep hygiene and prioritizing sufficient and restful sleep is an often overlooked but important modifiable risk factor in overall health."
