Filter by:The purpose of this study is to evaluate the feasibility of conducting a future randomized control trial that will compare the efficacy of sleep behavioral interventions in a high-risk community including adapted sleep hygiene and yoga. The investigators will conduct a 40 person 12-week randomized control trial (RCT) in low-income housing population where half the participants will receive a community adapted sleep hygiene intervention (SH) and half will receive a community adapted sleep hygiene intervention and a yoga intervention. The investigators will evaluate the feasibility of recruiting from our target community, randomizing individuals to interventions delivered in community rooms with home-based practices, and delivering the targeted interventions with high adherence and fidelity.
It is well known that sleep is essential for brain development and learning. Infants require extensive sleep for development of the hippocampus, pons, brainstem, and midbrain and for optimizing physical growth. It is also essential for brain plasticity; the genetically determined ability of the infant brain to change its structure and function in response to the environment. Studies in young animals have shown that sleep deprivation leads to increased programmed cell death, smaller brain size, and loss of brain plasticity, all of which have negative long-term impact on behaviour and learning ability. Infant massage, a form of systematic tactile stimulation by human hands, improves sleep hygiene. Very little is known about how massage influences early brain development but it is certainly linked to the theory of environmental enrichment, which has been well established in animal models. The aim of this project is to optimise the infant's sensory experience through a multi-sensory enrichment programme, including massage (a massage utilising a scented lotion before sleep each day), to encourage more structured sleep and ultimately show improved developmental and cognitive outcomes.
Preterm newborn sleep deprivation due to medical interventions and environmental characteristics of the Neonatal Intermediate Care Unit (NICU) can increase morbidity and developmental deleterious effects. The aim of this study is to test the effect of earmuffs on sleep pattern of preterm neonates. Prospective, randomized, controlled, crossover study conducted in NICU of two teaching hospitals from São Paulo, Brazil. The effect of earmuffs use was analyzed through polysomnography measurement during four "Quiet times" periods. It was also analyzed sleep related variables during 24 hours of the day. Preterm newborns characteristics and clinical characteristics were also analyzed.
Low oxygen at altitude causes pauses in breathing during sleep, called central sleep apnea. Central sleep apnea causes repeated awakenings and poor sleep. Low oxygen itself and the induced oxidative stress can damage mental function which is likely worsened by poor sleep. Reduced mental function due to low oxygen can pose a serious danger to mountain climbers. However there is also mounting evidence that even in populations of people that live at high altitudes and are considered adapted, low oxygen contributes to reductions in learning and memory. Therefore there is a serious need for treatments which may improve sleep, control of breathing and mental function during low oxygen. Melatonin is a hormone produced in the brain during the night which regulates sleep patterns with strong antioxidant and anti-inflammatory properties. A study previously reported that melatonin taken 90 mins before bed at 4,300 m (14,200 ft) induced sleep earlier, reduced awakenings and improved mental performance the following day. However how melatonin caused these effects was not determined. Therefore this study aims to determine how melatonin effects control of breathing, sleep and mental performance during exposure to low oxygen.
The primary objective is to explore the relationship between experimental condition (placebo or PowerOff) and sleep quality between pre-study and post-study. In addition, volunteers will wear actigraphy watches that collect objective measures of sleep, such as total sleep time, and these data points will be compared pre- and post-study.
The aim of this study is to examine the neurobehavioural and glucose metabolic responses to two successive cycles of sleep restriction and recovery in adolescents, and to determine the benefits of napping on cognitive performance, alertness, mood and glucose metabolism. Using a split-sleep design, 60 participants, aged 15 to 19 years old, are divided into a nap and a no-nap group. Both groups undergo two cycles of sleep restriction and recovery over a period of 15 days. The no-nap group receives a 6.5-hour sleep opportunity on sleep restriction nights, with no daytime nap opportunity. The nap group receives a 5-hour sleep opportunity on sleep restriction nights, and has a 1.5-hour nap opportunity the following afternoon.
In the majority of intensive care units, nurses work 12 hour shifts that consist of days and nights. Shift work outside of 6am-6pm has been reported to cause fatigue, induce sleep disorders, and cause metabolic disturbances. This shift to a nocturnal 'day' rather than diurnal, can result in reduced work performance, processing errors, accidents at work, absenteeism, and reduced quality of life. More chronically, those working at night have been shown to experience higher risks of heart disease, cancer and shorter median durations of life span. Much of this elevated risk is thought to be due to altered exposure to light, the dominant environmental cue regulating our circadian rhythms. As diurnal organisms much of our biology is regulated by the solar day. Acutely, bright light exposure (i.e., sun) regulates the phase of the biological clock principally through the suppression of melatonin, which biologically mediates increased alertness and in essence, 'our daytime alertness'. During the night melatonin gradually increases and induces tiredness and ultimately sleep. This, in part, is biology behind the use of melatonin in those with sleep disturbances or to mitigate jet lag, with cross-continental or transoceanic flights. In this study, the investigators will randomize nurses in the hospital to receive either high intensity white light (3,000 lux) or standard ambient white fluorescent (~400 lx) light for 10 hours during their night shift. This high illuminance light, rich in blue spectrum, is what diurnal creatures, like humans, are exposed to during the day. The lights may subsequently be equipped with blue filters (442 nm) to heighten the exposure to the rich blue spectrum light. Exposure will commence at the beginning of the night shift (~7pm) and continue for 10 hours. The rationale for terminating exposure prior to shift end is to foster an onset of sleep biology. At the end of each shift, the nurses will complete the Stanford Sleepiness Scale and the Psychomotor Vigilance Task (PVT). Saliva samples will be collected for melatonin level analysis and the nurses will complete sleep diaries at home. The investigators hypothesize that exposure to high intensity lighting during night shifts will reduce fatigue and enhance alertness and computational capacity that correlates with reduced melatonin.
This research project will examine whether experimental sleep extension in children alters the neural and behavioral mechanisms by which short sleep is a risk factor for emotional/behavioral problems. Children ages 5.0-5.9 years with chronic insufficient sleep (≤9 h/night for ≥6 months) will be randomized to either a sleep Extension or to an active Control group. Extension group parents will participate in a 1-month individualized behavioral sleep intervention to promote targeted sleep duration improvements before beginning a 2-week sleep Extension schedule (8 week protocol). Brain and behavioral assessments will occur at Baseline and post sleep Extension.
The overall goal of this project is to develop and to preliminarily validate a novel intervention to be delivered in the high school setting that integrates two evidence-based, school-based interventions for urban adolescents with proven efficacy: (1) Asthma Self-Management for Adolescents (ASMA), an intervention for adolescents with uncontrolled asthma and (2) the Sleep-Smart Program (Sleep-Smart), which focuses on sleep hygiene and behaviors in urban adolescents. The aim for Phase I is to develop and integrate school-based interventions to improve asthma self-management and sleep hygiene in urban high school students via interviews. The aims for Phase II are: (1) to evaluate the feasibility and acceptability of the intervention procedures; and (2) to assess the preliminary evidence of the effects of the intervention on improving sleep quality in urban high school students with persistent asthma over a 2-month follow-up period. This record is for Phase II only.
Due to the increased focus on education and changing lifestyle, college students are particularly susceptible to poor overall health and wellness due to inadequate sleep and poor dietary choices. This is particularly important because the behavioral choices college students make may affect their risk of chronic disease. This study will research these topics via an online survey, in person visit and stool sample.
