Bright Light Therapy for Cancer-Related Fatigue

Set aside time to rest, eat well, hydrate, and exercise regularly. These are common recommendations for self-managing cancer-related fatigue (CRF). Easier said than done, right?  Well, there’s another low cost and low burden intervention that sounds promising and may be worth exploring.

Growing evidence suggests that bright white light (BWL) therapy may  be effective in reducing CRF.  A 2014 study published in Psychooncology reported “CRF among clinically fatigued cancer survivors was significantly reduced among those who were exposed to BWL.” More recently, researchers concluded that “BWL was associated with greater improvements in fatigue and improvements on secondary psychosocial outcomes.” (Johnson, J. et al., 2017)

Cancer-related fatigue can be a debilitating side effect of cancer treatment that lasts beyond the treatment itself. Wouldn’t it be great if something as simple as bright white light exposure 30 minutes a day can help improve sleep and reduce feelings of fatique?
