Effects of Exercise on Sleep in Women with Breast Cancer: A Systematic Review.
Study Goal
The researchers aimed to evaluate the effectiveness of exercise interventions, particularly walking, in improving sleep deficiency among women with breast cancer.
Results Summary
Walking, primarily during chemotherapy, was associated with postintervention improvement in sleep deficiency in 11 out of 15 studies. Other interventions like yoga, qigong, and dance showed no significant differences between groups.

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.
