According to the Mirror, yoga can help improve the sleep of cancer patients.
Just two 75-minute sessions a week for four weeks helps people feel less tired, while they also report better social, physical and emotional wellbeing.
Experts said sleep problems typically affected between 30% and 60% of cancer patients and survivors.
It could be due to the side-effects of cancer drugs or fears over the implications of having the disease.
Researchers at the University of Rochester , New York, studied 245 women who had been treated for early-stage breast cancer , with an average age of 54.
All the women said they were suffering sleep problems and were quizzed about their energy and pain levels, sleep patterns, social interactions, sex life, mental state and ability to work.
