Laboratory studies have found that insufficient sleep duration and impaired sleep quality are associated with disease risk, including obesity, diabetes and heart disease. The limitation to the laboratory studies is that they are conducted in artificial environments that do not reflect real-world behavior. Although the epidemiologic studies do reflect habitual behavior, the vast majority of them rely on self-reported measures of sleep, which are only moderately correlated with objective measures of sleep.. The next logical step in the examination of sleep's role in cardiometabolic health is to conduct objective, detailed measures of sleep in people's homes. This project is a pilot study that will develop ideal methodologies for recording sleep in the home environment. Because there is currently is a gap between laboratory models of sleep loss and real world conditions, the ultimate goal of this research is to expand our work on sleep and cardiometabolic health outside of the laboratory. Given the strong evidence for a link between impaired and insufficient sleep and increased disease risk, it is critical that we understand how people sleep in their daily lives and what factors can impact sleep. This project will record sleep in people's homes using ambulatory polysomnography recordings and wrist actigraphy.

Sleep disorders are commonly under-recognized in the primary care setting and available screening tools are often are limited. The study inestigators hypothesize that the use of a novel su...
A randomized, controlled study to examine the effect of group treatment for insomnia (CBT-I) in an outpatient clinic compared with waiting list and treatment-as-usual (sleep-hygiene based ...
The main goal of this study is to assess whether use of earplugs has any effect on sleep, sleep apnea, and daytime sleepiness in individuals who snore.
People under stress, such as those caring for an ill family member, often have trouble with their sleep. The aim of this study is to see if reducing stress and changing a caregiver's slee...
This is an observational study to determine if the presentation of sensory stimulation during sleep can increase slow-wave activity during non-rapid eye movement sleep
The tendency for adolescents to have restricted sleep has been examined in numerous studies; however, the impact of sleep restriction on adolescents' neural activity during sleep (measured by electroe...
What can eyes tell us about what happens during sleep? Their movements split sleep into two distinct states - rapid-eye-movement (REM) or non-REM sleep. A new study now reveals that periodic pupil co...
Insufficient sleep has become recognized as a pervasive problem in modern society. Sleep debt is a novel measure of sleep adequacy that may be useful in describing those at risk for inadequate sleep. ...
The functions of sleep remain a mystery. Yet they must be important since sleep is highly conserved, and its chronic disruption is associated with various metabolic, psychiatric, and neurodegenerative...
Cognitive bias to sleep-related information is thought to be a core feature of sleep disturbances. The bias may enhance pre-sleep arousal, such as excessive worry about sleeplessness, which prevents p...
Periods of sleep manifested by changes in EEG activity and certain behavioral correlates; includes Stage 1: sleep onset, drowsy sleep; Stage 2: light sleep; Stages 3 and 4: delta sleep, light sleep, deep sleep, telencephalic sleep.
Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)
Movements or behaviors associated with sleep, sleep stages, or partial arousals from sleep that may impair sleep maintenance. Parasomnias are generally divided into four groups: arousal disorders, sleep-wake transition disorders, parasomnias of REM sleep, and nonspecific parasomnias. (From Thorpy, Sleep Disorders Medicine, 1994, p191)
A sleep disorder of central nervous system origin characterized by prolonged nocturnal sleep and periods of daytime drowsiness. Affected individuals experience difficulty with awakening in the morning and may have associated sleep drunkenness, automatic behaviors, and memory disturbances. This condition differs from narcolepsy in that daytime sleep periods are longer, there is no association with CATAPLEXY, and the multiple sleep latency onset test does not record sleep-onset rapid eye movement sleep. (From Chokroverty, Sleep Disorders Medicine, 1994, pp319-20; Psychiatry Clin Neurosci 1998 Apr:52(2):125-129)
Conditions characterized by disturbances of usual sleep patterns or behaviors. Sleep disorders may be divided into three major categories: DYSSOMNIAS (i.e. disorders characterized by insomnia or hypersomnia), PARASOMNIAS (abnormal sleep behaviors), and sleep disorders secondary to medical or psychiatric disorders. (From Thorpy, Sleep Disorders Medicine, 1994, p187)
Sleep disorders disrupt sleep during the night, or cause sleepiness during the day, caused by physiological or psychological factors. The common ones include snoring and sleep apnea, insomnia, parasomnias, sleep paralysis, restless legs syndrome, circa...
