Recent scientific research has tried to understand and quantify the buzz singers feel and has shown remarkable findings. All four key 'happiness hormones' are triggered by singing together: Dopamine, Serotonin, Endorphins and perhaps most importantly Oxytocin.
Oxytocin is a powerful bonding hormone which promotes trust and togetherness, and reduces stress and anxiety. Singing together produces significant levels of Oxytocin without physical contact and is the ideal way to improve genuine connections in your workplace.
Singing together also reduces Cortisol (the stress hormone) levels. As Time magazine states:
‘Group singing is cheaper than therapy, healthier than drinking, and certainly more fun than working out… if you walked into rehearsal exhausted and depressed, by the end of the night you’ll walk out high as a kite on endorphins and good will.’
Recent studies have also shown that choir singers heartbeats synchronise and experience an overall reduction in heart rate:
"When you exhale you activate the vagus nerve... that goes from the brain stem to the heart. And when that is activated the heart beats slower."
