The underlying factors for the disorder are physiological changes of the sleep-wake cycle, comorbid diseases and drug treatment. Cognitive behavioural therapy (CBT I) combined with light therapy and physical activity can be effective in the treatment of comorbid insomnia in older adults. Methods: Sixty-three (63) insomnia patients (47 female, 16 male) with an average age of 66.6 years participated in the program. Before and after the treatment, the participants completed questionnaires to assess their sleep quality (PSQI), day-time sleepiness (ESS), mood (BDI) and well-being (WHO-5-Index). In addition, they kept sleep diaries for six weeks. Results: Pre-post comparisons revealed a significant improvement in sleep latency and sleep quality, as well as a significant reduction of day-time sleepiness. In patients with both insomnia and depression, all depression scores improved slightly but significantly. Conclusions: Non-pharmacological combination treatment using CBT I, light therapy and physical activity seemed to be effective in older adults with comorbid insomnia and improve additionaly depressive symptoms.展开更多

The description of young adult sleep quality commonly includes the rationale that the independent schedule of the young adults coupled with their preferred social schedule, work and academic schedules leaves the planning for sleep to last place. Despite mentation and memory reductions with sleep deprivation secondary to poor sleep quality documented in young adults, the poor sleep quality prevails. This study is focused on the elements of arousal during a young adult’s day that may predispose them to elevated activation and difficulty relaxing sufficiently to fall asleep. It was hypothesized that light exposure was elevated in young adults with poor sleep quality. Light exposure in terms of overhead bright lights in classrooms and laboratories of the academic environment, bright light in terms of video monitors/TVs/tablets/phone exposure is sufficiently stimulating to cause cognitive activation was light exposure.展开更多
