Advanced breast cancer patients need quality sleep, not quantity

An American Academy of Sleep Medicine study reports the ratio of time asleep to time spent in bed is predictive of survival time for women with advanced breast cancer. The researchers found disruptive sleep patterns impacts the immune function of the cancer patient which decreases survival during a six-year period. 

"We were surprised by the magnitude of the relationship between sleep quality and overall survival even after we accounted for medical and psychological variables that typically predict survival," said lead author Oxana Palesh, PhD, assistant professor in the Department of Psychiatry and Behavioral Sciences at Stanford University and research director of the Stanford Cancer Survivorship. "Good sleep seems to have a strongly protective effect, even with advanced breast cancer."

This study involved 97 women (average age 55) with advanced breast cancer. Overall, participants spent approximately eight hours in bed each night but slept only slept for about six and a half hours. Full article >>
