Smartphones are increasingly integrated into everyday life, but frequency of use has not yet been objectively measured and compared to demographics, health information, in particular, sleep quality.The aim this study was characterize smartphone by measuring screen-time directly, determine factors that associated with increased screen-time, test the hypothesis is poor sleep.We performed a cross-sectional analysis subset 653 participants enrolled Health eHeart Study, an internet-based longitudinal cohort open any interested adult (≥ 18 years). Smartphone (the number minutes each hour screen on) continuously via application. For participant, total average were computed over 30-day windows.

Sleep problems and internet addiction among children and adolescents: a longitudinal study

Journal of Sleep Research, Journal Year: 2016, Volume and Issue: 25(4), P. 458 - 465

Published: Feb. 8, 2016

Although the literature has documented associations between sleep problems and internet addiction, temporal direction of these relationships not been established. The purpose this study is to evaluate bidirectional addiction among children adolescents longitudinally. A four-wave longitudinal was conducted with 1253 in grades 3, 5 8 from March 2013 January 2014. student participants were measured by parental reports on Sleep Habit Questionnaire, which catalogues early insomnia, middle disturbed circadian rhythm, periodic leg movements, terrors, sleepwalking, talking, nightmares, bruxism, snoring apnoea. severity students' self-reports Chen Internet Addiction Scale. Based results time-lag models, dyssomnias (odds ratio = 1.31), especially insomnias 1.74 2.24), sequentially predicted rhythm 2.40), regardless adjustment for gender age. This first demonstrate relationship insomnia predicting subsequently predicts rhythm. These findings imply that treatment strategies should vary according order their occurrence.

Optimizing sleep to maximize performance: implications and recommendations for elite athletes

Scandinavian Journal of Medicine and Science in Sports, Journal Year: 2016, Volume and Issue: 27(3), P. 266 - 274

Published: July 1, 2016

Despite a growing body of literature demonstrating positive relationship between sleep and optimal performance, athletes often have low quality quantity. Insufficient among may be due to scheduling constraints the priority relative other training demands, as well lack awareness role in optimizing athletic performance. Domains performance (e.g., speed endurance), neurocognitive function attention memory), physical health illness injury risk, weight maintenance) all been shown negatively affected by insufficient or experimentally modeled restriction. However, healthy adults are notoriously poor at self‐assessing magnitude impact loss, underscoring need for increased importance both elite practitioners managing their care. Strategies optimize quantity include approaches expanding total duration, improving environment, identifying potential disorders.

Abstract Sleep deficiencies, which include insufficient or long sleep duration, poor quality, and irregular timing of sleep, are disproportionately distributed among populations that experience health disparities in the United States. deficiencies associated with a wide range suboptimal outcomes, high-risk behaviors, poorer overall functioning well-being. This report focuses on (SHDs), is term defined as differences one more dimensions consistent basis adversely affect designated disadvantaged populations. SHDs appear to share many same determinants causal pathways observed for outcomes well-known disparities.

Molecules involved in innate immunity affect sleep and circadian oscillators vice versa. Sleep-inducing inflammatory molecules are activated by increased waking activity pathogens. Pathologies that alter molecules, such as traumatic brain injury, cancer, cardiovascular disease, stroke often associated with disturbed electroencephalogram power spectra. Moreover, disorders, insomnia disordered breathing, dysregulation of processes. Inflammatory both the central nervous system periphery can sleep.

Sex differences in sleep, circadian rhythms, and metabolism: Implications for precision medicine

Sleep Medicine Reviews, Journal Year: 2024, Volume and Issue: 75, P. 101926 - 101926

Published: March 21, 2024

The number of individuals experiencing sleep loss has exponentially risen over the past decades. Extrapolation laboratory findings to real world suggests that females are more affected by extended wakefulness and circadian misalignment than males are. Therefore, long-term effects such as metabolism disorders likely be prevalent in males. Despite emerging evidence for sex differences key aspects sleep-wake regulation, much remains unknown, often underrepresented research. This brief communication is intended highlight 1) how systematically impinge on regulation humans, 2) factors modulate metabolism, 3) meaning these precision medicine. Ultimately, justify factoring when optimizing individually targeted interventions humans.
