Emotional breathing is one of the possible causes of your weight gain
Breathing should be controlled by your physiology, but because in “modern” man the mind has taken over most of your physiology, your hunger, your breathing, your sex, your breathing has also been controlled by your mind.
Mind contains your thoughts and your feelings. It is true that you have bodily feelings, just like any living being, but it is the mind that decides for you what they mean.
The mind is a meaning making machine. And lately its main, self-assumed function is to say if something is negative or positive.
Let me give you an example: you sit at your computer and you suddenly have a stab of pain on the right side of your chest.
Depending on your predisposition, your mind will decide what the pain “means” and then start dictating your actions.
