Upright posture: It’s what defines us as humans and no other body does it better. Not only do we stand perfectly upright, but we walk about in a most efficient way that required significant evolutionary changes from head to foot.
Anthropologists suggest several different possible scenarios as to what environmental factors might have triggered upright posture and bipedalism in humans and hominids. The truth is, we don’t know. We can only guess, but by all accounts it was a behavioral decision on the part of the brain and that fateful decision led to some amazing anatomical and physiological changes.
For the most part the those changes were beneficial, especially for the brain. In fact, anthropologists attribute the large size of the human brain to the increase in brain blood flow caused by upright posture, as well as an enhanced cooling system. Some even believe that enhanced cooling had a greater impact on the increase in size of the brain than the increase in blood flow. They call it the radiator theory.
This blog will address some critical health care issues that I believe to be associated with upright posture. It will start with neurodegeneraive diseases because conditions, such as Alzheimer’s, Parkinson’s and multiple sclerosis are some of the most critical and costly health care issues we face in the industrialized world today. Yet, despite billions of dollars and decades in research, we still don’t have a clue as to what causes them. This is important because knowing the cause is the key to better treatment and possibly even prevention.
In the final analysis, I am going to present a strong case for doing further research into a brand new theory that has to do with upright posture and the unique design of the human skull, spine and circulatory system of the brain and their role in cranial hydrodynamics. Faulty cranial fluid mechanics may be the root cause of many neurodegenerative diseases.
