There is a reason why needling your head may fix your stomach - Demystify Internal Diseases
Many internal diseases, such as stomach issues, IBS, asthma, insomnia, and fatigue, can be attributed to dysfunction in the autonomic nervous system.
The autonomic nervous system, often referred to as the "fight or flight response," represents evolutionary adaptations that enhance the chances of survival in threatening situations.
However, when the fight or flight response is excessively frequent, intense, or triggered inappropriately, it can lead to various internal conditions.
Acupuncture, through the insertion of needles, focuses on rebalancing both the Yin (parasympathetic nervous system) and Yang (sympathetic nervous system), ultimately calming your mind.
