Reducing Cancer Side-effects With Systematic Light Exposure

The main purpose of this interdisciplinary proposal is to conduct two randomized controlled trial (RCT) of the efficacy of self-administered systematic light exposure (Bright White Light (BWL)), an innovative, low cost, and low burden intervention to treat cancer-related fatigue. Another common and often overlapping treatment side-effect is cognitive impairment. A secondary outcome of the proposed RCT is, thus, cognitive functioning. Finally, possible underlying chronobiological (circadian activity rhythms, sleep), biological (pro inflammatory markers), and neurophysiological (brain morphology) mechanisms of BWL will be explored.
