Harvard Medical School tells us that the human brain and nervous system are hard wired to distinguish music from other noise and to respond to rhythm and repetition, tones and tunes.

​

Put plainly, the brain responds differently to music. 

​

Additionally, singing helps breathing, speech and posture, and can improve circulation. The health benefits of singing are both physical (an aerobic activity that increases oxygenation in the blood stream and exercises major muscle groups in the upper body) and psychological.

 

Combine all of this with the positive benefits that we get from social interaction, and you've got an easily accessible, healthy exercise that can be achieved without strain - even sitting down.
