Sarah Wilson, neuroscientist and head of the University of Melbourne's School of Psychological Sciences, explained that when you sing, large parts of our brain light up with activity.
Wilson conducted a study on how the brain interacts when singing with MRI.
"There is a widespread singing network in the brain," Wilson says. "When we talk, half of the brain that deals with language lights up. But when we sing, both sides of the brain work."
"We also see the emotion nets in the brain interacting when we sing, as well as the areas that control the movements we need to produce the sounds and expressions also light up," Wilson added.
The explanation is that singing is an aerobic exercise that witnesses the release of endorphins, a good chemical for the brain, as it is associated with a general feeling of happiness and stress relief.
Singing is linked to what is possibly the biggest stress reliever in the body, which is breathing.
In a recent study, researchers found that focusing on controlling your breathing rate activates parts of the brain associated with emotions, attention, and body awareness.
