    Sleep Restriction Enhances the Daily Rhythm of Circulating Levels of Endocannabinoid 2-Arachidonoylglycerol Study Objectives: Increasing evidence from laboratory and epidemiologic studies indicates that insufficient sleep may be a risk factor for obesity. Sleep curtailment results in stimulation of hunger and food intake that exceeds the energy cost of extended wakefulness, suggesting the involvement of reward mechanisms. The current study ...

    Sleep Deficiency is a Modifiable Risk Factor for Obesity and Cognitive Impairment and Associated with Elevated Visfatin AIM: To study the interaction between sleep deprivation, obesity and cognitive functions, and the effect of following a balanced low caloric diet and increasing sleep duration on those variables. SUBJECTS AND METHODS: Ninety two obese females with mean age 47.00 ± 2.00 years and body mass index (BMI) 36.14 ± 3.00 kg/m² were ...

    Gut microbiota and glucometabolic alterations in response to recurrent partial sleep deprivation in normal-weight young individuals Objective: Changes to the microbial community in the human gut have been proposed to promote metabolic disturbances that also occur after short periods of sleep loss (including insulin resistance). However, whether sleep loss affects the gut microbiota remains unknown. Methods: In a randomized within-subject ...

    Morning Circadian Misalignment during Short Sleep Duration Impacts Insulin Sensitivity Short sleep duration and circadian misalignment are hypothesized to causally contribute to health problems including obesity, diabetes, metabolic syndrome, heart disease, mood disorders, cognitive impairment, and accidents [1–7]. Here, we investigated the influence of morning circadian misalignment induced by an imposed short nighttime sleep schedule on ...

    Sleep restriction alters plasma endocannabinoids concentrations before but not after exercise in humans Following binding to cannabinoid receptors, endocannabinoids regulate a variety of central nervous system processes including appetite and mood. Recent evidence suggests that the systemic release of these lipid metabolites can be altered by acute exercise and that their levels also vary across the 24-h sleepwake cycle. The present study ...

    Elevated ghrelin predicts food intake during experimental sleep restriction Objective—Sleep curtailment has been linked to obesity, but underlying mechanisms remain to be elucidated. We assessed whether sleep restriction alters 24-hour profiles of appetite-regulating hormones ghrelin, leptin and pancreatic polypeptide during a standardized diet, and whether these hormonal alterations predict food intake during ad libitum feeding. Methods—...

    Objective short sleep duration is associated with the activity of the hypothalamic-pituitary-adrenal axis in insomnia To evaluate the association between objective short sleep duration in patients with insomnia and changes in blood parameters related to hypothalamic-pituitary-adrenal (HPA) axis activity. Method: A cross-sectional pilot study was conducted in 30 middle-aged adults with chronic insomnia who were divided into 2 groups according to ...
