Cancer survivors often have problems getting a good night's sleep, sometimes for
years due to chemotherapy drugs, or other problems, a U.S. researcher says.
Karen Mustian of the University of Rochester Medical Center in New York said
some cancer patients might have trouble sleeping because of a worsening sleep
problem they had even before their cancer diagnosis.
Mustian analyzed data involving survivors with sleep problems who did yoga for
75 minutes twice a week for a month.
The study, published in the Journal of Clinical Oncology, found cancer survivors
who took up a form of gentle yoga slept better.
"While they showed greater improvements in their overall rating of their sleep,
they really showed improvements in feeling less tired during the day and napping
less," Mustian said in a statement.
