No one likes to have surgery, but if you find yourself needing to go under the knife, bring along your favourite tunes. A study by the Yale School of Medicine determined that patients who got to listen to their favourite music did better during certain procedures. They were given a local anesthetic to deaden the pain, but were otherwise remained awake and listening to music on headphones. They needed much less sedative because they were already relaxed by the music. This is good because sedatives can make you nauseous or make you itch everywhere—plus there can be rare severe complications. But before you get the wrong idea, music won’t help if you’re having open-heart surgery or a liver transplant, but this idea has major implications for things like the dreaded colonoscopy and other procedures where the patient supposed to stay awake. Think about it.
