Women who sleep well have a better chance of surviving advanced breast cancer, a new U.S. study has found.

The mean survival rate for women who were efficient sleepers was 68.9 months, about five years and eight months, compared to 33.2 months, two years and eight months, for poor sleepers, the Stanford University researchers found.

"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," lead author Oxana Palesh said in a release. "Good sleep seems to have a strongly protective effect, even with advanced breast cancer."

The study involved 97 women with advanced breast cancer who were an average age of 55. Overall, participants spent about eight hours in bed at night, but only slept for about 6.5 hours.

The research has been published in the journal Sleep.
