Can you really set out to be happy - happy, through singing? Yes, you can. Scientific studies show that singing is accompanied by physical changes that increase the feeling of happiness. Biochemically, this means: the body produces more endorphins and the bonding or "cuddle hormone" oxytocin.
But that is by no means everything. The first step is breathing. Deep abdominal and flank breathing, which receives special attention in singing lessons, has an effect on the autonomic nervous system (the parasympathetic nervous system): it calms and relaxes. "Try being afraid with a full chest and with your head up - which is all you have to do when you sing - [...]. It doesn't work at all." This is the apt comment by neurobiologist Gerald Hüther. At the same time, the deep Breathing while singing the metabolism. The whole body is better supplied with oxygen, comparable to endurance athletes. The brain is also better supplied with blood, so that the ability to concentrate increases.
It is a field where much research is still needed, but the evidence is already overwhelming: singing stabilises the heart rate, activates the circulation and improves the immune system. For example, singing produces more antibodies, which prevents colds. There are even reports of medical indications that singing could reduce inflammation levels in seriously ill patients or have a favourable effect on cancer.
But even in the midst of everyday life, the effects are clear. Singing makes people happy by reducing stress and improving cognitive performance. It is particularly remarkable that the mood-lifting effect of singing, at least of singing together, can be proven biochemically. Under the direction of the musicologist Gunter Kreutz, this was proven a few years ago in an experiment with a choir. After the choir rehearsals, the initially "grumpy"-unhappy choir members always felt measurably so much better that in the end they changed their name from the "choir of grumpy" to the "happy choir".
Whether together, in the shower or in a virtual room: singing is healthy and brings feelings of happiness to life. Therefore: Sing a Song, and: Be Happy!
