Welcome to Zen Chiropractic, your home for healing and optimal health
Many people would state that higher variability is better health in general. So many people make treatment plans for higher variability and state that it is the key to health! However, there is a consequence of high variability.
If your physiology, such as blood pressure, heart rate, skin temperatures, etc., remain in a random un-restored state, your life trajectory will come to an end. We are to have some predictable patterns and not changing so rapidly. Having “higher HRV” is a state of more random function to a degree.
When your brain and physiological state pass the edge of complexity and sophistication into randomness, you also have caused unhealthy conditions. This state is equal to letting a monkey steer a car. Just because there is a lot of activity at the steering wheel, does not mean that it is a coordinated function. This is past sophistication and complexity. On the other hand, there is a steering wheel lock seems stable in its activity, but that does not mean it is a healthy condition for the passengers in the back seat.
The key to understanding HRV is to be leaving the ranges of randomness and before entering a rigid physiological state is Health. Health is a well-trained chauffer who steers the car with calmness and adapting to the vehicle’s path through a timeline of life.
HRV is an objective measurement of the physiological state of adaptation to the environment. This concept is in large, very abstract and multi-variables that need consulting and help to understand your healthy state.
