Poor Sleep Affects Immune System Much Like Physical Stress

Study findings could have implications for jobs that require rotating shift work, researchers say.

Severe sleep deprivation has the same effect on the immune system as physical stress, according to a new study.

Researchers in the Netherlands and the United Kingdom found sleep loss triggers the production of white blood cells, known as granulocytes, particularly at night.

“The granulocytes reacted immediately to the physical stress of sleep loss and directly mirrored the body’s stress response,” explained the study’s lead author, Katrin Ackermann, a ...

Pesticide Tied to Sleep Problem

REM sleep behavior disorder, a rare condition, appears to share some risk factor associations such as occupational pesticide exposure with Parkinson’s disease.

A rare sleep disorder characterized by disturbances of rapid eye movement (REM) sleep shares some environmental risk factors with Parkinson’s disease, an international case-control study suggested.

For example, occupational pesticide exposure has been clearly linked with Parkinson’s disease, and in this study patients with REM sleep behavior disorder were twice as likely to have been exposed to pesticides as controls, ...

Sleep Can Sharpen Your Memory

External stimulation during sleep can reinforce what you have already learned, study shows.

External stimulation during sleep can help strengthen memory, which, in turn, can help you learn, a new study reports.

Researchers from Northwestern University noted that such stimulation could reinforce what people have already learned, but doesn’t help them gain new skills.

“The critical difference is that our research shows that memory is strengthened for something you’ve already learned,” the study’s co-author, Paul Reber, associate professor of psychology at Northwestern, ...

Apnea Linked to Neuropathy Risk in Diabetes

Future research hopes to find link between treating apnea and treating diabetes.

Obstructive sleep apnea (OSA) independently predicted coexistence of diabetic peripheral neuropathy, and the association remained significant after adjustment for multiple confounders, British investigators reported.

Two-thirds of a group of patients with type 2 diabetes had OSA, and 60 percent of the OSA subgroup had peripheral neuropathy. In contrast, the patients without OSA had a neuropathy prevalence of 27 percent.

The data also suggested potential mechanistic explanations involving nitrosative/oxidative stress and microvascular ...

Melatonin Can Help Seniors Get More Sleep

Taking melatonin resulted in small increases in total sleep time, sleep onset latency, and sleep efficiency in adults with insomnia over age 55.

Over-the-counter melatonin appears to provide a measure of sleep for older individuals who have insomnia, a meta-analysis showed.

Among individuals 55 and older, treatment with melatonin significantly improved sleep onset (by 6.36 minutes) and total sleep time (by 18.29 minutes), according to Jennifer Brault, MD, a resident in psychiatry at the University of Ottawa.

Sleep efficiency was improved by 3.54 ...

Sleep Apnea Therapy Might Ease Depression, Too

Positive airway pressure even helps patients who fail to use the treatment as prescribed, study finds.

Positive airway pressure, which is used to treat obstructive sleep apnea, may also help ease symptoms of depression among people with the sleep-related breathing disorder, a new study suggests.

Although depression is common among people with sleep apnea, researchers from the Cleveland Clinic Sleep Disorders Center found that patients who used positive airway pressure therapy had fewer depressive symptoms — even if they didn’t follow the ...

Hospital Noise Fractures Sleep, Slows Healing

Study showed that when sleep was disrupted, even for a few seconds, heart rates increased.

Nighttime noise in hospitals adds up to poor sleep, which may hurt healing when patients need it most, researchers found.

In a laboratory sleep study, recorded hospital sounds of overhead paging, IV alarms, squeaky carts, and the like disrupted sleep and raised heart rates, Orfeu M. Buxton, PhD, of Harvard and Brigham and Women’s Hospital in Boston, and colleagues reported.

Electronic alert sounds like ringing phones and IV ...

Short Sleep May Signal Stroke Risk

Chronically sleeping less than 6 hours per night significantly increased the rate of stroke symptoms among middle-age to older individuals of normal weight who had low risk of sleep-disordered breathing.

People who habitually sleep less than 6 hours appear to be at risk of developing symptoms that may predict future stroke, researchers reported here at the annual meeting of the Associated Professional Sleep Societies.

Study participants with normal body mass indices (BMIs) who slept less than 6 hours a night had a ...

Restless Leg Syndrome Drug Gets New Indication

FDA approves gabapentin enacarbil after a twelve week trial.

The FDA has approved the restless legs syndrome drug gabapentin enacarbil (Horizant) to treat postherpetic neuralgia.

The drug is administered in one 600 mg dose for the first 3 days of treatment, followed by 600 mg doses twice daily on day four and onward, a statement from makers GlaxoSmithKline and XenoPort said.

Patients with renal impairment should have adjusted doses, the statement added.

Safety and efficacy for the new indication were evaluated in a 12-week ...

Feeling Lackadaisical? Sleep Apnea May Be to Blame

Millions don’t know they have the airway disorder, experts say.

Millions of Americans plod through each day exhausted. Not because they’re working too hard, over-exercising or not taking enough vitamins.

The real reason, experts say, is because they unknowingly have a sleep disorder.

As many as 18 million Americans have obstructive sleep apnea, according to the National Sleep Foundation. But researchers estimate that as many as 90 percent of them don’t know they have it.

Sleep apnea causes people’s airways to become blocked while ...
