Bright Light Therapy for Depression Symptoms in Adults With Cystic Fibrosis (CF) and COPD

This project will occur on a 29-bed pulmonary step-down unit at a 1,600-bed academic medical center. This unit commonly treats patients with CF, COPD, and other pulmonary complications. The unit's patient care staff will be educated on the bright light lamps in order to prevent interruptions and to encourage compliance.
