Sleep Duration, Sleep Apnea, and Gray Matter Volume

Journal of Geriatric Psychiatry and Neurology, 2021
This study aimed to evaluate the effect of sleep duration on brain structures in the presence versus absence of sleep apnea in middle-aged and older individuals. The study investigated a population-based sample of 2,560 individuals, aged 49-80 years. The presence of sleep apnea and self-reported sleep duration were examined in relation to gray matter ...

Sleep duration, sleep quality and body weight: Parallel developments

Physiology & Behavior, 2013
The increase in obesity, including childhood obesity, has developed over the same time period as the progressive decrease in self-reported sleep duration. Since epidemiological studies showed an inverse relationship between short or disturbed sleep and obesity, the question arose, how sleep duration and sleep quality are associated with the development

Dreaming and Habitual Sleep Duration

Perceptual and Motor Skills, 1991
By demonstrating that habitual short-sleeping university students were less likely to report dreaming but were more likely to experience unpleasant dreams than their long-sleeping peers, we replicated Hartmann's 1973 results.

Sleep cycle content and sleep cycle duration

Electroencephalography and Clinical Neurophysiology, 1974
Abstract Sleep was recorded on 10 nights in each of seven older subjects (mean age 55) and nine younger normal subjects (mean age 22). The duration of the NREM-REM (non-rapid eye movement—rapid eye movement) sleep cycles was determined, starting from the onset of NREM sleep. In the older group an intra-individual comparison was made between the mean

Metabolomics, sleepiness, and sleep duration in sleep apnea

Sleep and Breathing, 2020
Although the mechanism is unclear, daytime sleepiness, a common sequela of obstructive sleep apnea (OSA), has been found to be correlated with a adverse cardiovascular outcomes. Reviewing metabolomics mechanisms of sleep disturbances and cardiovascular disease may help to explain this correlation.This review examines the current literature on the ...

Sleep Duration and Adiposity During Adolescence

Pediatrics, 2012
BACKGROUND AND OBJECTIVE: The association between sleep and obesity has been described in different age groups. However, there are not sufficient data to clarify the inconsistent results reported in adolescents. Our objective was to study the associations between sleep duration and adiposity at 13 and at 17 years of
