As a part of survival the body must make a sensory determination on whether a demand placed on the surface of the body is benign or a threat. It has a split second to do this. It must first determine where the demand is and then how grave the danger. It does this by activating the sensors in that area of the body. This requires blood and nerve supply to fuel this inquiry and hormonal supply to react to the need for inflammatory responses if indeed something serious is going on.
This reflexive response can be used to reset the stress mechanism.I look at the foot for example as a stress pattern. It can form over a day but also it can accumulate over a lifetime.
The simple act of rolling your foot on the foot roller or golfball can break up those patterns of stress and reset the tone of not only the foot but the entire body. It is a way to quite quickly and effectively put the brakes on not only the stress in your feet but also the stress in the rest of the body.
One thing to remember is that the feet's communication helps set the tension level for the whole body. If the signal is lost the result is simple. We fall down. It is all or nothing situation. The acts of standing and walking require a continuous stream of information to be successful. Any interruption can be castatrophic
Harnessing this sensory reflexive response is a way of focusing on the areas of the body that need our attention It is simple and it puts you in control making you your own body manager.
