Summary

Patients treated with chemotherapy complain of poor sleep, fatigue and depression. In addition, chemotherapy disrupts the body's internal "biological clock", which may make sleep, fatigue and depression all worse. Women with breast cancer undergoing chemotherapy are not exposed to much bright light and this may also contribute to the disruption of their body clock, because bright light is necessary for a strong biological clock. One of the easiest ways to strengthen the biological clock is by increasing bright light exposure. The correct timing of the light exposure will help the women feel more alert during the day.
