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.

Over time, disrupted nerve communication can contribute to elevated resting heart rate, blood pressure instability and reduced heart rate variability, which measures how well the heart adapts to stress and recovery. Nervous system regulation, particularly vagal tone, plays a major role in maintaining healthy heart rate variability. Vagal tone refers to the activity level of the vagus nerve, which is the main nerve of the parasympathetic nervous system that regulates the body’s relaxation response, heart rate and stress recovery.

Chronic stress compounds heart health issues. Stress often manifests physically as muscular tension, shallow breathing and limited thoracic movement. This keeps the sympathetic nervous system switched on, forcing the heart to work harder even at rest. When the body stays in this heightened state, inflammation increases, blood vessels stiffen and cardiovascular strain rises.

Posture and movement further influence the spine-heart relationship. Slouched posture compresses the chest, limits lung expansion and reduces oxygen efficiency. Sedentary lifestyles decrease spinal mobility, which can dampen parasympathetic activity. Movement, on the other hand, acts as a neurological reset—improving circulation, calming the nervous system and supporting heart function.

Spinal adjustments can improve nervous system function, reduce inflammation and enhance circulation. Adjustments have also been shown to lower blood pressure and ease strain on the heart. Infrared light is another complementary approach to cardiovascular wellness because it lowers blood pressure, improves circulation and reduces inflammation–all of which improves heart health, promotes healing and recovery and slows the progression of age-related heart disease and hypertension. Infrared light therapy also boosts cellular energy production in heart tissue, which can help prevent heart disease and help the heart heal after a heart attack. After a heart attack, mitochondria enter a shocked state and do not produce adequate energy (ATP). Infrared light supports ATP synthesis to help damaged tissues heal.

True heart health is more than a mechanical issue—it’s a communication issue. The heart relies on clear, balanced signals from the nervous system and those signals travel through the spine. By caring for spinal health, managing stress and supporting nervous system regulation, we can create a stronger foundation for long-term cardiovascular resilience.
