Physiological Explanation

[Bazile]

From time to time one feels the urge and it feels good to have a good stretch .

Also you are sitting there in a normal situation and automatically take a sharp intake of breadth .

Is there any physiological reason for the above ?

[Stargazer]

I do not refer to a sharp intake of breath but am aware of taking a very deep and long intake of breath now and again. I think it is because most of the time I (we) are not filling our lungs all the time, but are taking shallow breaths only partly filling our lungs to their full capacity. This may be what you are referring to.

Yawning is a reaction to a lowering of oxygen level in the blood.

//a very deep and long intake of breath now and again. //

Yep , a better description

[Bazile]

Do you mean the body detects a low level of oxygen in the blood and automatically forces you to take more oxygen in

[dannyk13]

Basile. yes, exactly that.
