Listening to the Wisdom of your Heart

Our bodies have a built-in system called homeostasis to respond to stress and maintain balance. The nervous system is critical in this process, controlling automatic bodily functions to keep us stable. Heart rate variability (HRV) measures the effectiveness of our nervous system in handling stress. It shows how well the vagus nerve regulates heart rate, a key part of the autonomic nervous system. The autonomic nervous system has two parts: the sympathetic and parasympathetic systems, which work together to manage stress and promote survival.

The sympathetic system provides energy during stressful events, while the parasympathetic system conserves energy and promotes calmness. The vagus nerve influences both parts of the autonomic nervous system, promoting emotional regulation and engagement when we feel safe and activating a low-energy response during extreme stress.

Chronic stress weakens the vagal break, leading to anxiety, depression, and relationship problems. Maintaining a healthy vagal tone is crucial for overall well-being. By understanding how our nervous system works and taking steps to manage stress, we can promote a robust vagal break and enjoy a better quality of life.


Optimal HRV is an online platform designed to help individuals optimize their vagal tone, manage stress levels, and improve overall well-being. Users can gain insight into their autonomic nervous system functioning through interactive tools and personalized metrics. The site utilizes heart rate variability (HRV) technology to measure a user’s vagal tone, the balance between their sympathetic (“fight or flight”) and parasympathetic (“rest and engaged”) systems.
