Can music relieve the pain of surgery and help recovery?
New research suggests playing music during operations can have a positive effect on both surgeons and those they treat.
A major study published in the Lancet says that patients who listen to music during and after an operation will feel less pain and have a speedier recovery - even if they had been under general anaesthetic.
The Department of Health said doctors should consider the findings.
The scientists want hospitals to suggest in NHS information leaflets that patients bring music devices and playlists into hospital with them.
