“…A similar study by Strand et al echoes these conclusions: the investigators found an inverse relationship between cardiorespiratory fitness, also measured by maximum oxygen uptake (VO 2max ) and symptoms associated with insomnia in a sample of over 3,000 Norwegian participants [40]. These results were further supported by two separate analyses of exercise levels and the incidence of insomnia symptoms in cohorts of over 12,000 [41] and 450,000 Chinese citizens [42]. Both studies found that decreased physical activity led to an increased risk for insomnia.…”

Although a substantial body of literature has explored the relationship between sleep and exercise, comprehensive reviews and definitive conclusions about the impact of exercise interventions on sleep are lacking. Electronic databases were searched for articles published between January 2013 and March 2017. Studies were included if they possessed either objective or subjective measures of sleep and an exercise intervention that followed the guidelines recommended by the American College of Sports Medicine. Thirty-four studies met these inclusion criteria. Twenty-nine studies concluded that exercise improved sleep quality or duration; however, four found no difference and one reported a negative impact of exercise on sleep. Study results varied most significantly due to participants' age, health status, and the mode and intensity of exercise intervention. Mixed findings were reported for children, adolescents, and young adults. Interventions conducted with middle-aged and elderly adults reported more robust results. In these cases, exercise promoted increased sleep efficiency and duration regardless of the mode and intensity of activity, especially in populations suffering from disease. Our review suggests that sleep and exercise exert substantial positive effects on one another; however, to reach a true consensus, the mechanisms behind these observations must first be elucidated.

An association between physical illness and sleep has been suggested. Disordered chewing might be a physical factor that is associated with sleep issues. This cross-sectional study aimed to determine whether chewing problems are associated with sleep in Japanese adults. Sleep and chewing issues were evaluated in 6,025 community residents using a self-reported questionnaire. The prevalence of poor sleep quality and sleeping for <6 h/day (short duration) were 15.6% and 29.4%, respectively. Multivariate logistic regression analyses showed that prevalence of poor sleep quality was significantly associated with self-reported medical history (odds ratio (OR), 1.30; p<0.001), self-reported symptoms (OR, 4.59; p<0.001), chewing problems (OR, 1.65; p<0.001), and poor glycemic control (OR, 1.43; p=0.035). The prevalence of short sleep duration was also significantly associated with female sex (OR, 1.23; p=0.001), self-reported symptoms (OR, 1.60; p<0.001), chewing problems (OR, 1.30; p=0.001), and being overweight (OR, 1.41; p<0.001). In conclusion, chewing problems were associated with poor sleep quality and short sleep duration among Japanese adults.

“…While Spielman, Caruso, and Glovinsky's () “3‐factor” model provides a framework for understanding the interaction of acute and chronic processes in the aetiology of insomnia, epidemiological research has consistently identified personal attributes associated with elevated insomnia risk, including female gender, older age, degraded health, lower socio‐economic status (Ohayon, ) and, more recently, physical inactivity (Kim et al, ). Low levels of physical activity have been reported as significant risk factors for both prevalent and incident insomnia (Chen, Steptoe, Chen, Ku, & Lin, ; Janson et al, ; Kim et al, ; Morgan, ; Sporndly‐Nees, Asenlof, & Lindberg, ). Typically, however, studies to date have focused either exclusively on leisure activities and/or report only dichotomized (higher versus lower) activity levels.…”

Both very low and very high levels of regular physical activity have been associated with degraded sleep quality. Cross-national variations in habitual physical activity levels, therefore, may contribute to cross-national differences in insomnia prevalence. The present study assesses and compares the extent to which weekly durations of moderate-intensity physical activity contribute to insomnia risk. Demographic, sleep, physical activity and general health profiles were obtained from a convenience sample of 9,238 adults drawn from five countries (South Africa, Australia, China, South Korea and the UK) using social media. Insomnia prevalence, using DSM-5 criteria, ranged from 4.1% (China) to 14.8% (UK). Evaluating risk using logistic regression adjusted only for age and gender, the lowest level of activity (<10 continuous min per week) was associated with significant insomnia risk (odds ratio = 1.37; 95% confidence interval = 1.05-1.79; p < 0.05). However, when adjusted for all covariates except country, only the highest level of physical activity (>300 min per week) was associated with significantly increased insomnia risk (odds ratio = 1.30; 95% confidence interval = 1.03-2.51; p < 0.05). Risk associated with high activity remained after the addition of "country" to the model (odds ratio = 1.31; 95% confidence interval = 1.02-1.69; p < 0.05). Across all models, female gender, low-rated health, low education and older age consistently increased insomnia risk. These cross-national data indicate that extremes of inactivity/activity can significantly influence insomnia risk independent of country. Insomnia risk associated with very low levels of activity may be mediated by poorer health and disadvantageous social status. However, while very high levels of activity increase insomnia risk independent of health and demographic factors, they may also confound with personally and occupationally demanding lifestyles.

Physical activity, smoking, and the incidence of clinically diagnosed insomnia

Abstract: Inactive adults and smokers are at higher risk for incident insomnia, highlighting the importance of a healthy lifestyle and pointing to strategies such as encouraging smoking cessation and physical activity to avoid insomnia among adults.
