Heart rate variability (HRV) measures the irregular rhythms of a normal, healthy heart in a resting state. These beat-to-beat changes are crucial as they indicate the heart’s flexibility and the body’s ability to adapt to both internal and external stressors. An optimal HRV balance is essential for the healthy regulation of organ systems controlled by the Autonomic Nervous System (ANS).

HRV represents the balance between the Sympathetic Nervous System (SNS) and the Parasympathetic Nervous System (PNS), influencing heart rate based on thoughts, emotions, and physical activity. The rhythms of the heart impact brain function, creativity, problem-solving, and decision-making.

Understanding HRV and its relationship with the ANS empowers individuals to examine their mental, emotional, and physiological processes, promoting inner health and well-being. Positive thoughts and emotions, such as acceptance, appreciation, gratitude, and love, promote order and balance in the ANS, whereas negative thoughts and emotions can lead to disorder, potentially fostering disease.
