Singing in a choir makes you happier. It boosts all the good hormones in your brain.
Heres an article: Slate and here's an excerpt.
"Music is awash with neurochemical rewards for working up the courage to sing. That rush, or “singer's high,” comes in part through a surge of endorphins, which at the same time alleviate pain. When the voices of the singers surrounding me hit my ear, I'm bathed in ...
dopamine, a neurotransmitter in the brain that is associated with feelings of pleasure and alertness. Music lowers cortisol, a chemical that signals levels of stress. Studies have found that people who listened to music before surgery were more relaxed and needed less anesthesia, and afterward they got by with smaller amounts of pain medication. Music also releases serotonin, a neurotransmitter associated with feelings of euphoria and contentment."
How cool is that?
