Intervention programs seeking to mitigate alcohol-related harms should focus on reasons for use when they are the most developmentally salient. PMID: 28728638 [PubMed - in process]

Sleep duration and self-rated health, as the main outcome of interest, were measured as self-reported. As potential covariates, we included sex, age, smoking status, alcohol consumption, physical activity, sedentary behavior, psychological distress, and body mass index.Results:Approximately 30% of participants slept 7–8 hours, 17.4% were short sleepers (categories 10 hours ...

The objective of this study was to identify mechanistically plausible factors, beyond negative affect, that may explain why individuals experience nightmares.Method846 participants from the UK general population completed an online survey about nightmare occurrence and severity (pre-occupation, distress, and impairment), negative affect, worry, depersonalisation, hallucinatory experiences, paranoia, alcohol use, sleep duration, physical activity levels, PTSD symptoms, and stressful life events. Associations of nightmares with the putative predictive factors were tested controlling for levels of negative affect. Analyses we...

ConclusionNo relationship was found between symptoms of CMD and the onset of severe musculoskeletal time-loss injuries. However, professional football players who suffered from severe musculoskeletal time-loss injuries are likely to develop subsequent symptoms of CMD. This study emphasizes the need for an interdisciplinary medical approach, which not only focuses on the physical but also on the mental health of professional football players. An early identification of players at risk of symptoms of CMD, such as those suffering from severe musculoskeletal injuries, creates the opportunity for an interdisciplinary clinical m...

Conclusion This study explored the relationship between having a sense of purpose in life and sleep quality and sleep disorders. Researchers found generally, having a greater sense of purpose in life was associated with better quality of sleep and a decreased likelihood of sleep disorders like sleep apnoea and restless leg syndrome. The researchers suggest this may be down to people having better overall physical and mental health. Although these are plausible hypotheses, there are a few points to note. As with the majority of cohort studies, it isn't possible to prove cause and effect and fully rule out the i...

Abstract ObjectiveEpidemiological and laboratory‚Äźbased driving simulator studies have shown the detrimental impact of moderate, legal levels of alcohol consumption on driving performance in sleepy drivers. As less is known about the time course of decaying alcohol alongside performance impairment, our study examined impairment and recovery of performance alongside decaying levels of alcohol, with and without sleep restriction. MethodsSixteen healthy young males (18–27 years) underwent 4 counterbalanced conditions: Baseline, Alcohol (breath alcohol concentration [BrAC]
