Sleep deficiency is common and distressing for women with breast cancer throughout the care continuum. This article describes the scope and quality of evidence related to exercise interventions to improve sleep in women with breast cancer. Fifteen studies met the criteria and 12 were judged to be excellent quality. The most frequent intervention was walking, primarily during the time of chemotherapy. Eleven studies reported postintervention improvement in sleep deficiency. Most yoga, qigong, and dance intervention studies reported no differences between groups. Emerging evidence exists for the effectiveness of aerobic exercise to improve various sleep outcomes in women with breast cancer.

PURPOSE/OBJECTIVES: To update the state of the science on sleep-wake disturbances in adult patients with cancer, focusing on insomnia in the areas of prevalence, mechanisms and models, measurement, interventions, and implications for practice, health policy, education, and research. DATA SOURCES: Published articles, books, book chapters, MEDLINE, CINAHL, and PsycINFO computerized databases. DATA SYNTHESIS: Since the 2004 conference on Sleep-Wake Disturbances in People With Cancer and Their Caregivers, an increased focus has existed on the prevalence and distress experienced by patients with cancer with sleep-wake disturbances, particularly insomnia. Evidence suggests that altered physiology directly related to the cancer process may play a prominent role in disrupting sleep, circadian rhythms, and hypothalamic-pituitary-adrenal axis-regulated processes. Reliable and valid objective and subjective measurements for screening and assessing sleep-wake disturbances are ready for use in clinical and research settings, and an increasing amount of intervention studies have reported sleep-wake outcomes in adult patients with cancer. CONCLUSIONS: Cognitive behavioral therapy interventions are likely to be effective, but effectiveness has not been established for complementary, education or information, or exercise interventions. IMPLICATIONS FOR NURSING: Multidisciplinary research teams should test the effectiveness of interventions to reduce sleep-wake disturbances in adult patients with cancer. Settings should create the infrastructure to initiate and sustain evidence-based oncology nursing practice, clinicians should educate the public about sleep, and public policies should promote adoption of healthy sleep patterns and early diagnosis and treatment of sleep disorders.
