Human beings are Endotherms - meaning we are able to regulate our own temperature. When, for example, the body’s temperature exceeds the mean, the heart rate increases and the blood vessels vasodilate; opening to circulate blood and heat to the extremities in order to cool the body’s core for homeostasis. Alternately, if the core temperature cools down, the body will constrict the blood vessels through vasoconstriction, allowing less blood and warmth to the exterior in an attempt to contain the heat in the interior.
Blood simply conducts heat. The homeostasis of internal temperature, through the sending out or storing of more blood, is called Thermoregulation. It’s this mechanism that directly influences both health and function; which, throughout life, depending on age and lifestyle habits, adjusts to balance the body’s relationship in accordance with the solar movements.
In health, the body’s core and the movement of heat inwards and outwards needs to be uninhibited. The slightest obstruction or change, much like the sun’s angle, will create temperature and environmental variations, not consistent with function and wellbeing.
It’s this internal mechanism along with our relationship to external influences that directly impacts bodily function; how gas, fluids and blood warm and cool, transform and transport, distribute and store. If you take the time to read and understand the mechanics behind Thermodynamics, it will reveal a completely new understanding of Chinese Herbal Medicine and Acupuncture and its effects on function and health.
