Filter by:There are three components to this study: a Field Trial, a Shift Worker Survey, and Focus Groups. The Investigators will study the effectiveness, feasibility, and acceptability of an 8-h sleep intervention in older night workers in an operational environment. The overall goal of the Field Trial is to minimize sleep deficiency and negative outcomes resulting from that, including sleepiness and performance impairments during night shift work. The Shift Worker Survey is designed to understand some of the demographic and operational factors that enable or inhibit the ability of individual shift workers to adopt this intervention. The Focus Groups are designed to glean in-depth information from older shift workers who indicate that they are unable or unwilling to adopt an 8-h sleep timing intervention. Understanding these factors will assist in refining and targeting the intervention to those individuals who will be most likely to benefit from the intervention sleep timing strategy.
Nonstandard time-schedules work are widespread in the world of work. Shift and night work have been shown to be responsible for a desynchronization of biological rhythms, associated with melatonin secretion impairment and sleep disturbances. However, while health consequences of night and shift work are widely recognized and represent a major public health concern (High Authority of Health 2012 Recommendations and National Agency for Public Health Food, Environment and Work 2016 Report), the mechanisms by which the circadian system is affected by shift work remain poorly understood. Indeed most of the studies in the fields are cross-sectional, based on few blood or urinary samples in a single work position, in workers whose shift work patterns are often misidentified and heterogeneous. Moreover, few studies have assessed melatonin secretion alterations in relation to objective sleep measurement (actigraphy). The aim of this study is to assess the dynamics of melatonin secretion adaptation in 12-hour shift work and to correlate these data to sleep-wake cycle recording.
This project examines 1) the effects of appropriately timed bright light on adaptation (in terms of sleep and sleepiness) to three consecutive night shifts; and 2) the effects of such bright light on re-adaptation (in terms of sleep and sleepiness) to a day-oriented schedule after the night shift period.
The purpose of this research is to test the hypothesis that those with non-traditional work schedules (e.g. shift workers) have a higher cardio-metabolic risk than those with traditional work schedules (e.g. day workers), and that both accumulated sleep debt and the degree of circadian disruption predict the elevated cardio-metabolic risk. The findings of this research are expected to increase our understanding of physiologic tolerance to non-traditional work schedules and provide the basis for the development of methods for the early detection of adverse health effects and determine coping strategies for the millions of workers with non-traditional work schedules.
This study aims to evaluate the effects of aroma massage to sleep quality of the nurses and staff during night shift.
Firefighters work some of the most demanding schedules known under highly stressful and demanding conditions. The need to work frequent extended shifts and long work weeks leads to acute and chronic partial sleep deprivation as well as misalignment of circadian phase. Sleep disorders are common, costly, and treatable, but often remain undiagnosed and untreated and it is likely that a significant proportion of firefighters suffer from undiagnosed sleep disorders which will further impair their sleep and exacerbate fatigue.In the current proposal, we aim to address the health, performance and safety issues related to fatigue in firefighters and test the effectiveness of a Comprehensive Firefighter Fatigue Management Program (CFFMP) that we have termed 'Operation Healthy Sleep.'
Firefighters frequently work extended duration shifts and long work weeks which have adverse effects on alertness, health, safety and performance. This protocol uses a survey instrument to examine the effects of extended duration shifts on safety outcomes (e.g., motor vehicle crashes, accidents, injuries), health (e.g., diagnosis and treatment of sleep disorders, improved general health indices, decreased number of sick days), and performance (e.g., decreased response time). This study will expand understanding of the nature, scope, etiology and consequences of firefighter fatigue and increase our ability to develop guidelines that can be generalized across fire departments throughout North America. This study could provide an avenue to make lasting policy improvements that could enhance the safety, health, and performance of firefighters.
The purpose of this study is to test the effects of eszopiclone on daytime sleep and overnight wakefulness in shift workers.
The purpose of this study is to determine if a modified version of the Sleep Enhancement Fatigue Reduction Training (SEFRT) system can improve sleep and health-related symptoms and quality of life in experienced shift-working nurses.
The purpose of this study is to determine if a modified version of the Sleep Enhancement Fatigue Reduction Training (SEFRT) system can improve sleep and health-related symptoms and quality of life in shiftwork-naive new nurse graduates.
