Inclusion Criteria
  • 21 years of age or older
  • Newly diagnosed with stage I-III breast cancer

  • Experiencing disrupted sleep (determined by Pittsburgh Sleep Quality Index)
  • Morning or evening types (determined by Horne-Ostberg Morningness-Eveningness Questionnaire (MEQ)
  • Sighted
  • Mentally competent to consent
  • Able to under English
Exclusion Criteria
  • Concurrent malignancy
  • Undergoing other cancer treatments
  • Engage in shift work or travel across more than 3 time zones within 2 weeks prior to study
  • Known history of seasonal affective disorder or substance abuse
  • Current diagnosis of major Axis I psychiatric disorders, neurological impairments, or muscular dystrophies
  • Regularly use steroid or other immunosuppressive medications
  • Take prescribed sedative hypnotics or sleep medications because these conditions may affect fatigue and/or sleep/wake patterns.
  • Have eye conditions (glaucoma or retinal disease), problems triggered by bright light (e.g. migraine), or take photosensitizing medications (e.g. some porphyrin drugs, antipsychotics, antiarrhythmic agents)
