I never would have directly thought of the benefits of singing, let alone that there was research into it, but it is one of those things that should be obvious.
There’s a growing body of research into the impact of singing on well-being. We now know, for example, that group singing raises your pain threshold. And that it releases oxytocin into your bloodstream, which helps promote feelings of trust and safety.
Singing also enables fast social bonding. It breaks the ice so you feel closer as the group, even if you don’t yet know anything about each other. The team behind this research also suggest that the social bonding effect of singing may even have been vital in enabling modern humans to sustain larger social networks than their evolutionary ancestors. And that, in turn, may have helped them colonise risky environments worldwide. Those early singers were no slackers.
When you sing with other people your heartbeats sychronise – which may explain why singing together can create a sense of shared perspective. Choral singing can certainly improve mood, enhance quality of life, and lead to greater happiness, reduced stress and better emotional well-being. But, whether you sing alone or with others, the simple act of singing raises your heart rate variability, which in turn improves both your well-being and social cognition.
