Bright Light Therapy Improves Sleep Quality in Cancer Survivors, Pilot Study Shows
Daily sessions of bright light exposure improve sleep quality in fatigued cancer survivors, researchers found. The study, “The Effect of Systematic Light Exposure on Sleep in a Mixed Group of Fatigued Cancer Survivors,” appeared in the Journal of Clinical Sleep Medicine. Cancer patients, including those with ovarian cancer, report sleep disturbances at a higher rate than the general population. A significant proportion of cancer survivors (23% to 44%) experience insomnia even years after treatment. Sleep disturbances are associated with fatigue and are considered part of the cancer symptom cluster, which also includes cognitive impairment and depressive mood, and greatly reduces quality of life. Pharmacologic and non-pharmacologic interventions, including exercise and cognitive-behavior therapy, have shown only modest benefits in the treatment of cancer-related fatigue. Researchers evaluated the effectiveness of systematic light exposure, which had shown positive effects in breast cancer patients undergoing chemotherapy. The pilot study (NCT01873794) included 54 adult participants (average age about 54; 75% women) who had completed treatment with chemotherapy with or without radiation for breast cancer or gynecological cancer, or stem cell transplantat for blood-related malignancies at least 3.5 years before they enrolled in the study.The study was conducted at the Icahn School of Medicine at Mount Sinai in New York City.
