This paper aims to outline the literature that situates sleep as a public health concern. In particular, it discusses the bi‐directional relationship between insomnia and mental health.

This paper reviews and presents the findings of other relevant research, relating the discussion to policy and practice.

Getting good quality sleep is essential, but insomnia is a huge problem and may be the most commonly reported mental health complaint in the UK. Mental health influences insomnia, and insomnia can lead to mental health problems. Sleep medication is a commonly prescribed treatment for insomnia, but evidence from robust research suggests that cognitive behavioural therapy for insomnia (CBTI) is the most successful treatment for chronic insomnia.

GPs need evidence‐based information on the importance and benefits of sleep and to be able to recognise sleep problems in primary care. CBTI needs to be represented in NICE guidance for insomnia. CBT‐influenced methods could be implemented as low level interventions as part of a stepped care framework.

Reviewing the academic literature on sleep problems related to mental health reinforces the importance of sleep as a health issue, which can be assessed in primary care as appropriate.

Typologies of sleep problems have usually relied on identifying underlying causes or symptom clusters. The purpose of this paper is to explore the value of using the patient's own reasons for sleep disturbance.

Using secondary data analysis of a nationally representative psychiatric survey the patterning of the various reasons respondents provided for self‐reported sleep problems were examined. Over two thirds (69.3 per cent) of respondents could identify a specific reason for their sleep problem with worry (37.9 per cent) and illness (20.1 per cent) representing the most commonly reported reasons. And while women reported more sleep problems for almost every reason compared with men, the patterning of reasons by age showed marked variability. Sleep problem symptoms such as difficulty getting to sleep or waking early also showed variability by different reasons, as did the association with major correlates such as worry, depression, anxiety and poor health.

While prevalence surveys of “insomnia” or “poor sleep” often assume the identification of an underlying homogeneous construct, there may be grounds for recognising the existence of different sleep problem types, particularly in the context of the patient's perceived reason for the problem.

A typology based on reasons presents a different snapshot of the landscape of insomnia. Using patient's reasons to underpin a sleep nosology is an alternative way of sub‐dividing patients' symptoms which has some face validity given the “subjective” associations between reasons and symptoms.

The purpose of this paper is to discuss recent papers on trauma, sleep and psychotic experiences to highlight the lack of attention given to sleep.

A search was carried out to find recent papers on psychosis or schizophrenia, trauma and sleep.

Papers tended to focus on trauma and psychosis, or on sleep and psychosis, but not on trauma, sleep and psychosis. The two papers discussed in most detail here focussed on sleep difficulties from either a service user or professional perspective. Both concluded that sleep difficulties need more attention. The author also discussed evidence suggesting that stress and trauma cause sleep difficulties and that these, in turn, are an important cause of psychotic experiences. Severe or prolonged stress may also directly cause some psychotic experiences.

The two main papers highlight for the first time in detail service users’ own experiences of sleep difficulties, and how mental health professionals view them, suggesting more help is needed. Other papers suggest that sleep is overlooked in research into the causes of psychosis. There is growing evidence that people have sleep problems before psychotic experiences, and that many have experienced severe or prolonged stress due to life events and circumstances, often in childhood. Given that stress can interfere with sleep, it is time to investigate further the role of stress and sleep in the development and maintenance of psychosis.

The conventional customer lifecycle fails to acknowledge the “sleeping” stage between regular patronage and churn, particularly prevalent in the hospitality industry. This study constructs an awakening model to regain “sleeping” guests.

342 questionnaires from Macau using partial least squares-structural equation modeling (PLS-SEM) were analyzed. The model was compared across different membership levels through multigroup analysis.

The results indicate that the point policy can awaken “sleeping” guests by influencing their perceived value, regret, and integrated satisfaction with a shorter “sleeping” period. Two path coefficients showed significant differences among basic and elite members.

Companies with loyalty programs should implement a transitional period before resetting points, leveraging altruistic point policies to awaken “sleeping” guests via direct communication. This strategy mitigates the negative impact of finite point expiration policies, enhancing customer re-engagement and point utilization.

Our study focuses on a crucial facet of hotel marketing—customer regain strategies. By identifying customer segments who have not revisited the hotel group for more than twelve months, we confirm the concept of “sleeping” guests. This term offers a nuanced perspective, distinguishing “sleeping” guests from generic lost customers. The “sleeping” guest segment provides valuable insights for enhancing targeted and effective marketing activities in the highly competitive hotel industry.

This chapter covers two behaviors that greatly affect college students’ mental health and wellbeing: eating and sleeping. The chapter begins with a definition of eating disorders and distinguishes clinically disordered eating from other forms of problematic eating. The chapter describes common eating disorders among college students: anorexia nervosa, bulimia nervosa, avoidant restrictive food intake disorder (ARFID) and binge eating disorder. The chapter then discusses measures of problematic eating among college students, including the SCOFF, the Eating Disorder Inventory and the Eating Concerns subscale of the Counseling Center Assessment of Psychological Symptoms (CCAPS). Next, the chapter discusses the prevalence of problematic eating among college students. Cultural considerations are described, with particular attention paid to gender, sexual orientation and ethnicity. Causes of problematic eating among college students are discussed, and the consequences of problematic eating are explored, from shame to medical complications to death. Treatment options are detailed, as are barriers to seeking professional help. The chapter follows a similar structure in covering healthy and problematic sleep behaviors among college students. In particular, the chapter explores measures of sleep quality, the prevalence of problematic sleep among college students, their causes and consequences, as well as strategies for correcting poor sleep and interventions for promoting healthy sleep habits.

This study examines the antecedents and dynamics of authoritarian leadership and extends the effects of managers' sleep quality to employee behavior.

On the basis of self-regulation theory, 513 unit day samples were analyzed using cross-level path analysis and a Monte Carlo simulation test.

Managers' sleep quality is positively related to authoritarian leadership and positive emotions play a mediating role. Authoritarian leadership is positively related to employees' counterproductive behavior. Managers' sleep quality affects employees' counterproductive behavior through managers' positive emotions and authoritarian leadership.

Individuals should learn to reduce stress and maintain a positive mood. Organizations should reduce employees' overtime work and work stress and find other ways to improve employees' sleep quality.

First, we considered authoritarian leadership to be dynamic and studied it on a daily basis. Second, we studied the antecedents of authoritarian leadership from the perspective of leaders' states (sleep quality and emotions). Third, we discussed the effect of managers' sleep quality on employee behavior.

Employees have gained increased flexibility in organizing their work in time and space, that is boundaryless work. Managing the boundaries between work and personal life would seem to be crucial if one is to psychologically detach from work during leisure in order to unwind and get sufficient sleep. Drawing from a sample of Swedish professional workers (N = 3,846), a theoretical model was proposed testing the inter-relationships between boundaryless work in time and space, weekly work hours, psychological detachment, sleeping problems and sleep duration using a structural equation modelling (SEM) analysis. Findings showed that working boundlessly in time, that is spread out during the working day and week, was directly associated with both long weekly work hours and lack of psychological detachment. In contrast, working boundlessly in space, that is at several different places, was inversely associated with weekly work hours and had no association with psychological detachment. Psychological detachment, in turn, was directly associated with sleeping problems and inversely associated with sleep duration. Sleeping problems were inversely associated with sleep duration. Employees with long weekly work hours had a low degree of sleeping problems. There was also no association between long weekly work hours and sleep duration. These findings contradict earlier research, however, we interpret these findings as that if one works a great deal but is able to mentally detach from work-related feelings and thoughts during free time, then sleep will not be hampered because perseverative cognitions associated with prolonged biological activation will have been interrupted. As such, psychological detachment can be regarded as the mechanism that mediates the relationships between working ‘anytime’ and long weekly work hours, and sleep. It was concluded working boundlessly in time increases the likelihood for long weekly work hours and lack of psychological detachment. Hence, employees working ‘anytime – all the time’ run the risk of ‘always being on’ resulting in disturbed sleep.

Throughout human history and around the world, co-sleeping was the context for human evolutionary development. Currently, most of the world’s peoples continue to practice co-sleeping with infants, but there is increasing pressure on families in the West not to co-sleep. Research from anthropology, family studies, medicine, pediatrics, psychology, and public health is reviewed through the lens of a developmental theory to place co-sleeping within a developmental, theoretical context for understanding it. Viewing co-sleeping as a family choice and a normative, human developmental context changes how experts may provide advice and support to families choosing co-sleeping, especially in families making the transition to parenthood. During this transition, many decisions are made by parents “intuitively” (Ball, Hooker, & Kelly, 1999), making understanding the developmental consequences of some of those choices even more important. In Western culture, families are making “intuitive” decisions that research has shown to be beneficial, but families are not receiving complete messages about benefits and risks of co-sleeping. Co-sleeping can be an important choice for families as they make the life-changing transition to parenthood, if individualized messages about safe infant sleep practices (directed toward their individual family circumstances) are shared with them.
