Toddler Snoring May Lead to Unruly Behavior

Loud snoring, which occurs in nine percent of children two to three years of age, related to behavior problems.

Persistent snoring in preschoolers, which puts them at risk for worse behavior, is most common in children in poorer families and in those breastfed for short times or not at all, a prospective study showed.

After adjustment for demographic variables, frequent snoring was significantly associated with socioeconomic status and duration of breastfeeding, according to Dean W. Beebe, PhD, of the University of Cincinnati ...

Poor Sleep Hampers Vaccine Effectiveness

Adults who slept less than six hours nightly weren’t adequately protected from virus.

Lack of sleep can reduce the effectiveness of vaccinations, according to a new study.

Researchers measured the sleep patterns of 125 adults who received the three-shot course of the vaccine to protect against hepatitis B. The immune systems of participants who slept less produced fewer antibodies in response to the vaccine and blood tests showed that they did not meet the standard of protection from the virus.

People who slept ...

Two Chemical Systems Help Keep Muscles Paralyzed During REM Sleep

What is actually going on inside of our bodies when we dream?

Imagine this: You’re having a vivid dream of something chasing you. You run and leap across buildings, jumping and spinning.

What keeps your body from actually acting out these movements during REM sleep, even as they play out so actively in your brain?

Scientists have pinpointed the mechanism that keeps our muscles paralyzed, and they say that understanding could be a boon to finding treatments for sleep conditions and disorders ...

Bad Sleep Tied to Cognitive Decline

Three different studies all support the concept that sleep disturbances are associated with cognitive decline among older individuals.

Common sleep problems may be a sign of impending cognitive decline or even Alzheimer’s disease, according to results of several studies reported here.

Sleeping too little or too much, abnormal breathing during sleep, and excessive daytime sleepiness all were significantly associated with cognitive impairment — years later in some cases.

The studies were presented at a “featured research session” during the Alzheimer’s Association International Conference ...

Sleep Better: How to Be a Star Sleeper

Exercise and sexual activity are just two ways to help you catch some more z’s.

Instead of bragging about how little sleep we need, what if we rewarded star sleepers for their healthy habits?

First, we’d have to identify those key qualities that make someone good at sleep. A recent survey from Consumer Reports may offer some clues.

The publication asked more than 26,000 subscribers about their sleep habits. Nearly 60 percent reported feeling tired or having trouble falling or staying asleep at ...

Why Do We Sleepwalk?

Fact or fiction: Waking a sleepwalker is not a good idea? Read on.

There’s spaghetti in the bathroom sink, the laptop’s in the laundry basket, and please tell me that is not urine dripping down the refrigerator door.

Either a group of college kids took over the house for the night or there’s a sleepwalker on the loose. Sleepwalking, or somnambulism, is a disorder that happens when people do some activity besides snoozing while they’re still asleep. There are lots of potential ...

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, ...
