Breathing Biomechanics and Mechanical Stimulation of the Pancreas

The current view is that breathing (breathing biomechanics) only supplies air with oxygen to the body (inhaling) and expels air containing metabolic waste products (exhaling).

A few years ago, I realised that breathing also mechanically stimulates internal organs. And that one of the necessary conditions for optimal work of internal organs requires optimal mechanical stimulation. Most physical activities provide a specific mechanical stimulation to internal organs, but mechanical stimulation induced by breathing processes differs from mechanical stimulation caused by physical activities. Until now, I have identified seven types of mechanical stimulations that affect the human body. Still, the rest of this article will discuss just mechanical stimulation caused by the breathing process.

a) The inhalation process supplies the body air with oxygen while also decompressing internal organs (the trunk’s cavities expand during inhalation).

b) The exhalation process (expelling air containing metabolic waste products) deflates the lungs while at the same time compressing internal organs (the trunk’s cavities shrink).

Compression of internal organs happens because cavities shrink during exhalation.

Decompression of internal organs happens because cavities expand during inhalation.

The internal organs decompress during inhaling, and during exhaling, they compress. Mechanical stimulation of internal organs consists of their decompression during inhalation and compression during exhalation.

On the one hand, breathing supplies oxygen to the body; on the other hand, it mechanically stimulates the activity of every internal organ. The way how we breathe is the way how our internal organs are mechanically stimulated.

1) The human body gets air with oxygen by any type of breathing, whether it is upper chest, natural, or belly breathing – also called diaphragmatic breathing. (Oxygen (air with oxygen) isn’t the problem, but the situation is different regarding mechanical stimulation of internal organs).

2) Certain types of breathing don’t provide optimal mechanical stimulation to internal organs. Some internal organs are overstimulated (mechanically) by certain breathing types, and some are understimulated (mechanically).

a) Upper chest breathing doesn’t provide sufficient mechanical stimulation to internal organs below the upper chest.

b) Belly breathing, particularly lower-belly breathing, doesn’t provide enough mechanical stimulation to the internal organs in the trunk’s upper part. At the same time, it induces excessive mechanical stimulation on the internal organs located in the middle and lower part of the trunk.

During belly breathing, particularly the lower belly breathing, internal organs in the lover and middle part of the trunk are overstimulated and internal organs in the upper part of the trunk are understimulated. It is because only or mainly the lower part of the trunk expands during inhalation and constricts during exhalation.

Breathing mainly with the upper chest doesn’t provide sufficient mechanical stimulation to the internal organs located in the middle and lower part of the trunk. It is because only or mainly the upper part of the trunk expands during inhalation and constricts during exhalation.
