Acupuncture works based on the need of the human body to have healthy, soft tissue and good circulation.
When muscles or connective tissues start to tighten, blood flow changes start to happen. We know because of the study of fluid dynamics in physics that when fluid moving in a closed environment changes in one place, it changes in all places. So, to put it simply, if you have tension or impaired circulation in one area of your body, it literally impacts all of your body.
That might not bother you too much if you’re overall pretty healthy, but if you have inflammation or stress, or you’re not sleeping well the impacts of these changes to your body can start to accumulate. In theory, acupuncture can work to reverse these physical changes, which helps your body work much more efficiently!
