Premise Two of the 5 premises is to understand that a human body can be described as a series of interconnected chambers. The brain and spine are housed in their own chamber, as are the body organs, the lungs and the heart. The regulation of pressure is probably carried out by the correct functioning of the intercostal muscle function and our posture. As soon as we are born out of a fluid environment into a gravity dependent environment we have to start pressure regulation.
The brain and spine chamber interconnect with the abdominal chamber, which interacts with the pleura and the pericardium. In the adult human heart rate can be affected by pressing on and holding for long enough the eyeballs. The eyes are a well accepted sign of cranial pressure. The wiring that connects the heart rate and the eyes helps with the process of pressure regulation in the adult human.
The back can be a site of increased pressure as can the head. Cranial therapy can be very helpful to not only infants but to adults as well. Cranial faults can be a reason for reoccurring pain syndromes. Maintaining the function of the rib cage and an upright posture is not just aesthetically pleasing it helps us to regulate the pressure changes of our environment and the movement forces we develop in our daily activities. Classically increased intensity of discomfort / pain on laying down can be a sign of pressure dys-regulation.
