Drawing in Breath

By

I decided to look into the science of how we breathe, and I read this description:

“The diaphragm is a thin skeletal muscle that sits at the base of the chest and separates the abdomen from the chest. It contracts and flattens when you inhale. This creates a vacuum effect that pulls air into the lungs. When you exhale, the diaphragm relaxes and the air is pushed out of lungs.”

I see now that when I consciously breathe in I am really just tensing a muscle, and the low pressure space created, pulls in the air. I thought I was actively pulling in breath. I certainly have the sensation that I am actively drawing in breath. I believe that I am pulling in the air. But I am not.

Having read about the vacuum created when the diaphragm contracts, I sat and contracted my diaphragm but without any intention to breathe in, just contracting the muscle – and I felt air being sucked into my chest.

I tried tensing my diaphragm at the same time as closing my throat to stop air being drawn in. Try it, you can feel the tussle between the two bits of your body.
