You are limiting yourself with fear.
The fear to express yourself and your desires clearly, or allowing others to dominate and control you, can be physically reflected in breathing difficulties. Issues such as asthma, wheezing, choking, hypoventilation, and emphysema are common emotional projections.
This heart code could also indicate that your habitual breathing pattern has become shallow because you feel inadequate or incompetent. Shallow breaths keep your body’s sympathetic nervous system in a constant state of stress, which can lead to long-term health issues. Consciously changing your breathing patterns can assist with the emotional process of overcoming fear.
