Circadian disruption: What do we actually mean?

European Journal of Neuroscience, Journal Year: 2018, Volume and Issue: 51(1), P. 531 - 550

Published: Nov. 7, 2018

The circadian system regulates physiology and behavior. Acute challenges to the system, such as those experienced when traveling across time zones, will eventually result in re-synchronization local environmental cues, but this is oftentimes accompanied by adverse short-term consequences. When are chronically, adaptation may not be achieved, for example case of rotating night shift workers. transient chronic disturbance most frequently referred "circadian disruption", many other terms have been proposed used refer similar situations. It now beyond doubt that contributes health disease, emphasizing need clear terminology describing their goal review provide an overview describe disruption discuss quantifications experimental observational settings with a focus on human research, highlight limitations currently available tools.

Sleep is essential for the body, mind, memory, and learning. However, relationship between sleep quality, stress, academic performance has not been sufficiently addressed in literature. The aim of this study was to assess quality psychological stress among medical students investigate performance.This cross-sectional targeted all their preclinical years at a Saudi college 2019. All were asked complete an electronic self-administered questionnaire comprising Pittsburgh Quality Index (PSQI), Kessler Psychological Distress Scale (K10), questions on students' current overall grade point average, other demographic lifestyle factors. associations categorical variables analyzed using Pearson's Chi-squared test 0.05 significance level.The mean PSQI score 8.13 ± 3.46; 77% participants reported poor 63.5% some level (mean K10 score: 23.72 8.55).

Sleep deprivation can impair attention, mood, and performance; however, few effective sleep education programs are available. The aim of this study was to assess the effect a website, Stay Awake (sleeptostayawake.org), on behaviors college students.College students (age 18 years or older) attending public Midwestern university were randomized control intervention groups. All subjects completed baseline surveys that included demographics, Pittsburgh Quality Index, Patient Health Questionnaire, knowledge, measures sleepiness circadian rhythm. group then undertook online intervention. Surveys repeated at 1 week 8 weeks.Students who participated 295 controls 254 subjects. mean age 21.9 ± 4.1 41.7% male.

Sleep is an important determinant of collegiate athlete health, well-being and performance. However, social physical environments are often not conducive to obtaining restorative sleep. Traditionally, sleep has been a primary focus athletic training neglected due competing academic, demands. Collegiate athletics departments well positioned facilitate better culture for their athletes. Recognising the lack evidence-based or consensus-based guidelines management athletes, National Athletic Association hosted summit in 2017.

Validation of the Sleep Regularity Index in Older Adults and Associations with Cardiometabolic Risk

Scientific Reports, Journal Year: 2018, Volume and Issue: 8(1)

Published: Sept. 17, 2018

Abstract Sleep disturbances, including insufficient sleep duration and circadian misalignment, confer risk for cardiometabolic disease. Less is known about the association between regularity of sleep/wake schedules risk. This study evaluated external validity a new metric, Regularity Index (SRI), among older adults (n = 1978; mean age 68.7 ± 9.2), as well relationships SRI using data from Multi-Ethnic Study Atherosclerosis (MESA). Results indicated that irregularity was associated with delayed timing, increased daytime sleepiness, reduced light exposure, but independent duration. Greater also correlated 10-year cardiovascular disease greater obesity, hypertension, fasting glucose, hemoglobin A1C, diabetes status. Finally, perceived stress depression, psychiatric factors integrally tied to These results suggest useful measure in adults. Additionally, may represent target early identification prevention Future studies clarify causal direction these effects, mechanisms underlying links risk, utility interventions reducing
