Sleep Lab & Sleep Medicine

If you often find yourself wide awake in the wee hours, you're not alone. Nearly two-thirds of American adults experience regular sleep disruptions. Lack of sleep can contribute to following risks:

Insomnia doesn't need to be a life sentence. Many disorders can be diagnosed with overnight sleep study, or polysomnograms. An overnight stay at Virginia Hospital Center's Sleep Lab could pinpoint what ails you. Our physicians will simultaneously record a patient's brainwaves, muscle activity, heart rhythms, belly and chest wall effort, air flow to the nose and mouth, snoring patterns, blood oxygen levels and nerve impulses to the eye. These factors can help identify the onset of REM (rapid eye movement), dream states and possible impediments to sound sleep.

Common Medical Conditions that Can Cause Insomnia

Sleep Apnea
Sleep apnea, a condition affecting some 15 million Americans, is among the most common disorders diagnosed at the Lab. Those affected experience repetitive, involuntary breathing pauses throughout the night due to absent or impaired air flow through the back of the throat. This results in an adrenaline surge, which, in turn, causes an elevation in respiratory effort, blood pressure, lung circulatory pressures and heart rate. The outcome is sleep disruption, loud, irregular snoring, carryover fatigue and headaches. Recent studies have also shown sleep apnea to be a risk factor for high blood pressure, stroke, and heart disease.

Men are twice as likely as women to suffer from sleep apnea. Commonly associated with obesity and large neck size, the condition can be exacerbated by alcohol, tobacco and sedative use. Once diagnosed, however, it can be easily treated with a bedside device, roughly the size of a toaster, called Nasal CPAP (continuous positive airway pressure). A mask attached to the machine blows a constant stream of air into the nose and mouth, acting as a pneumatic splint to prevent the throat from collapsing.

Restless Leg Syndrome (RLS)
Another common sleep disorder affecting 3-5% of U.S. adults is RLS. Individuals with RLS often experience a pins-and-needles sensation in their legs and feel an irresistible urge to move, making sleep initiation difficult. RLS is often associated with anemia, pregnancy, kidney problems and back problems. Although it can affect individuals of all ages, it is most often seen in older adults. Fortunately, RLS can be treated with a range of therapies, from muscle rubs to iron or magnesium tablets. Severe cases are sometimes controlled with the same drugs used to treat Parkinson's disease.

Stress and other health conditions can impact your sleep as well.

If you experience insufficient sleep, don't put yourself at risk of negative health consequences. To schedule an appointment, call our Sleep Lap at 703.236.7171.

Dream On: Why Sleep is Critical for Good Health

By Sarah Markel, Northern Virginia Magazine | February 2017

By many measures, Northern Virginians are among the healthiest—and longest living—people in the nation. Yet when it comes to getting their daily dose of shut-eye, it’s a different story. Virginians rank 25th in the nation when it comes to healthy sleep practices, with more than a third of adults in the state reporting that they sleep less than seven hours each night. That’s behind nearly half the nation. What’s worse, nearly three quarters of teens in the state report sleeping less than the eight to 10 hours recommended for adolescents.

That’s a problem because insufficient sleep, whether voluntary or caused by a sleep disorder like insomnia or obstructive sleep apnea, is linked to a host of negative health consequences, including high blood pressure, obesity, diabetes, heart disease, memory loss and premature death. Read more
