About this trial
Cancer-related fatigue (CRF) is a severe and persistent side effect of cancer and its treatment, affecting up to 40% of patients and significantly reducing quality of life. Recent research suggests that circadian rhythm disruption has been implicated as a possible related pathophysiological mechanism underlying CRF. Circadian rhythms are 24-hour cycles regulating physiology and behavior through environmental cues called "zeitgebers." Strengthening these cues-such as light exposure, physical activity, and eating-may help reduce CRF.
This project will develop and test the optimal combination a home-based, low-burden chrono-behavioral therapy (ChronoBT) targeting these zeitgebers.
