Where did that air come from???

[Noticibly F.A.T]

Can someone please explain to me why when you sit down after you have had a big day, you let out a huge breath of air. Where does this air come from, cause i don't realise if i beath in heavily before i sit down. Why do we do this???? :bugeye:

There is a considerably larger amount of air in your lungs than is let out in a single regular exhale. When you are working, walking, standing, these activities are generally associated with work and do not provide a sense of relaxation.

When you sit down the activity is providing less stress on the body and you let go of more air. Extremely beneficial if you sing to hone your body to use up that excess air.
