Abstract: Sleep loss causes mood disturbance in non-clinical populations under severe conditions, i.e., two days/nights of sleep deprivation or a week of sleep restriction with 4–5 h in bed each night. However, the effects of more-common types of sleep loss on mood disturbance are not yet known. Therefore, the aim of this study was to examine mood disturbance in healthy adults over a week with nightly time in bed controlled at 5, 6, 7, 8 or 9 h. Participants (n = 115) spent nine nights in the laboratory and were given either 5, 6, 7, 8 or 9 h in bed over seven consecutive nights. Mood was assessed daily using the Profile of Mood States (POMS-2). Mixed-linear effects models examined the effect of time in bed on total mood disturbance and subscales of anger-hostility, confusion-bewilderment, depression-dejection, fatigue-inertia, tension-anxiety, vigour-activity and friendliness. There was no effect of time in bed on total mood disturbance (F(4, 110.42) = 1.31, p = 0.271) or any of the subscales except fatigue-inertia. Fatigue-inertia was higher in the 5 h compared with the 9 h time in bed condition (p = 0.012, d = 0.75). Consecutive nights of moderate sleep loss (i.e., 5–7 h) does not affect mood but does increase fatigue in healthy males.

Abstract: Validated sleep and mental health assessments are grossly underutilised in athletic populations. Previous studies have predominantly focused on elite competitors. To form a more representative view of sleep and mental health in athletes, we conducted a large-scale survey that is more inclusive of different competition levels and playing statuses. Current and retired athletes (N=1007) participated in an online survey. Utilising validated tools, we screened for sleep difficulty and disordered breathing (ASSQ), depression (CESD-R), anxiety (GAD-7), and poor quality of life (PWI-A). Participants were categorised as currently competing, retired, or unable to play, from an amateur, sports institute/university, semi-professional, or professional level. Retired athletes (41.7%) were more likely to report sleep apnoea symptoms than competing athletes (24.5%) and those unable to play (27.1%) (p& .001). No differences in sleep difficulty were observed across playing status (p=.212). Competition level did not affect sleep difficulty (p=.595) or sleep apnoea symptomology (p=.274). Sleep apnoea symptomology was predicted by age (p& .001), BMI (p& .001), and quality of life (p=.002), but not anxiety (p=.544) or depression (p=.102). Sleep difficulty was predicted by the same factors, in addition to depression (p& .001). Findings suggest that sleep problems affect all athletic populations, with most respondents (72.4%) reporting mild to severe sleep difficulty. While competition level may not affect athletes’ sleep health, we identified athletic retirement, age, BMI, depression, and poor quality of life as risk factors for disordered sleep. Therefore, protective strategies for mental health are needed for athletes from all competition levels and playing statuses.

Abstract: Sleep and mental health are important aspects of human health that work concurrently. However, sleep and mental health disorders are often overlooked and undiagnosed in sport due to the negative stigma associated with them. Evidence suggests that athletes are disproportionately affected by mental health issues and sleep problems. Internal and external pressures contribute to psychological distress. Variable competition times, travel and stress are detrimental to sleep quality. Retirement from sport can deteriorate sleep and psychological wellbeing, particularly for those who retired involuntarily and identify strongly with their athletic role. When untreated, these issues can manifest into a range of clinical disorders. This is concerning, not only for compromised athletic performance, but for general health and wellbeing beyond sport. Previous research has focussed on sleep and health independently among currently competing, or former, athletes. To date, no research has comprehensively assessed and compared sleep complaints and mental health issues between these two cohorts. Moreover, research has failed to obtain data across a variety of different competition levels, sports, and genders, leaving the current scope of the literature narrow. Comorbid conditions (e.g., concussion history, obesity), ex-college athletes, and mental health has been the focus of existing literature post-retirement. Future research would benefit from employing both quantitative and qualitative methodologies to comprehensively assess the prevalence and severity of sleep and mental health disorders across current and retired athletes. Research outcomes would inform education strategies, safeguarding athletes from these issues by reducing negative stigmas associated with help-seeking in sport and ultimately increase self-guided treatment.
