Music played during surgery can help patients recover. A study was conducted by doctors in India. They played flute music to a female patient. She was having an operation. Before the operation, doctors gave the woman drugs to put her to sleep. The drugs blocked pain signals and relaxed the woman's muscles while she was asleep. However, even when the drugs made the woman sleep, the part of her brain that helps her listen stayed partly active. Doctors say she could still hear music. This means she needed fewer painkilling drugs, woke up faster, and was more alert after surgery.

The lead researcher explained why music helps patients. She said music is more than just simple background music. She said music helps patients to feel less pain and need fewer painkillers. A co-researcher, who is a specialist in anaesthesia and music therapist, agreed. She believes music is important in the operating theatre. She said: "Our aim is early discharge after surgery. Patients need to wake up clear-headed, alert… and ideally pain-free." She said music helps manage pain and reduces patients' stress after they wake up.
