What is Heart Rate Variability?
HRV is a valuable tool to assess the cardiac autonomic nervous system. The test result reveals individual general fitness, the degree of risk of sudden heart death and the efficiency of the autonomic nervous system, aka ‘the master regulator of metabolism’.
The human heart rate continually responds to all our internal and external stressors. The heart rate will adapt to any stress derived from physical exertion, emotions, temperature fluctuations, exposure to radiation etc.
The HRV test can be useful in determining the efficiency of the autonomic nervous system which helps to maintain functions that are not under our conscious control such as respiration and digestion.
Your HRV result will indicate how your ANS is currently functioning, your stress index, your capacity to burn fat, which is required for effective weight loss, your energy levels, the ability to adapt to stress of any origin, and the ability to regenerate and repair.
What is the Autonomic Nervous System?
The ANS, is also referred to as the master regulator of metabolism. It has two divisions: the sympathetic and the parasympathetic. Each side works in opposition to the other, yet they work together to maintain balance. For example, sympathetic stimulation speeds up the heart rate, and parasympathetic stimulation slows down the heart rate. Together, the sympathetic and the parasympathetic divisions work together to maintain the correct heart rate, as well as the functioning of all the various organs, glands and systems of the body.
