Cardiovascular health is crucial for longevity and well-being, yet nearly 20% of Americans over 65 have heart disease. While most associate cholesterol, blood pressure, diet and exercise with heart health, there is another overlooked player. The nervous system directly affects the heart with the spine acting as a bridge facilitating communication between them. Spinal health and nervous system regulation significantly impact heart rhythm, blood pressure, inflammation and long-term cardiovascular health.
It is critical to understand the spine-heart connection when discussing cardiovascular health. The Autonomic Nervous System (ANS) is a network of nerves that controls automatic bodily functions such as heart rate, breathing and blood pressure. ANS consists of the sympathetic and parasympathetic nervous system. The sympathetic system activates the “fight or flight” response, increasing heart rate and blood pressure during stress. The parasympathetic system promotes “rest and digest,” and slows the heart to support recovery. Heart health depends on balance between these two systems.
The spine is a communication highway between the brain and the heart with nerves that influence cardiac function exiting the spinal cord from the neck (cervical spine) and upper back (thoracic spine). If spinal movement is restricted, posture is poor or tissues around the spine become chronically tight, nerve signaling can become distorted.
