Most conversations about the nervous system stop at the brain and spinal cord. Occasionally, they include the vagus nerve. Far less often do we hear about the enteric nervous system, even though it contains over 100 million neurons and operates with a level of autonomy that rivals the brain itself. Recent peer-reviewed studies, such as a 2023 research article on ENS-immune system connections, stress the critical role the ENS plays in preserving bodily homeostasis, further anchoring its importance in the scientific community.
Often called “the second brain,” the enteric nervous system (ENS) lives primarily in the gut. But that description undersells its reach. The ENS is deeply interconnected with fascia, vascular systems, and sensory signaling throughout the body. It plays a central role not only in digestion but in affective regulation, intuition, and overall nervous system balance.
In my work, I've noticed that when people begin to regulate their nervous system more fully, one of the first areas to respond is the gut. This isn't accidental, it's biological. I've observed in practice how clients often experience a noticeable softening in gut tension following simple breathwork exercises. For example, one client came in following a notably stressful week, describing a tight knot in their stomach. Through guided breathing sessions, they reported a gradual yet definite sense of ease in their gut, and how their digestion felt smoother and less erratic by the end of the session. This distinct change shows the extent to which intertwined breathwork and gut response are in the context of nervous system regulation.
What the enteric nervous system actually does
The enteric nervous system governs digestion, motility, enzyme release, blood flow, and immune signaling in the gastrointestinal tract. Unlike other parts of the nervous system, it can function independently of conscious thought. It constantly gathers information from the internal environment and responds in real time.
But what’s less discussed is how sensitive the ENS is to vibration, pressure, rhythm, and frequency, as demonstrated by recent findings on mechanosensitive neurons (Smith and colleagues, 2022).
The gut is richly innervated and surrounded by layers of fascia, connective tissue that transmits mechanical and electrical signals throughout the body. Fascia is not inert wrapping; it is a sensory organ in its own right. It holds tension, memory, fluid, and information.
When the fascia is restricted or the nervous system is chronically dysregulated, the ENS receives distorted signals. Over time, this can show up as digestive discomfort, anxiety, fatigue, or a persistent sense of being “off,” even when lab results look normal.
Fascia as a communication network
Fascia forms a continuous, body-wide matrix that connects muscles, organs, nerves, and fluids. According to Akash, fascia is a continuous network of connective tissue that surrounds and connects muscles, bones, nerves, and organs, and its semi-elastic, fluid-filled structure allows it to transmit mechanical forces such as vibration throughout the body.
Research indicates that sensory nerve signals are stronger after passing through fascia at specific points, suggesting that well-hydrated and pliable fascia may help signals travel more efficiently. When it is restricted or densified, commonly due to stress, trauma, inflammation, or prolonged fight-or-flight, communication becomes noisy or muted.
This is where entrainment comes in.
Entrainment and the nervous system
Entrainment is a phenomenon in which biological systems synchronize to external rhythms. The heart, brainwaves, breath, and nervous system all entrain naturally when given consistent, coherent input. As you read this, take a moment to place a hand on your belly. Notice any subtle vibrations or movements, inviting your focus on the pattern of your breath. This micro-practice can enliven the concept of entrainment for you in real time. Sound and vibration are especially effective forms of entrainment because they move through tissue, fluid, and fascia simultaneously. According to a 2022 study, exposure to low-frequency whole-body vibration by sonic waves was found to significantly increase parasympathetic nervous system activity and decrease sympathetic nervous system activity, supporting a more regulated state in the body.
Digestion improves. Breath deepens. The gut softens. And something else frequently emerges: clarity.
The gut, intuition, and sensory awareness
The idea of “gut instinct” is not metaphorical. The enteric nervous system sends more information to the brain and is constantly scanning for safety, coherence, and alignment.
When the nervous system is overwhelmed, this signaling can feel chaotic, presenting as anxiety, indecision, or hypervigilance. But when regulation is restored, the gut becomes a reliable source of information.
People often describe this as intuition returning. Not intuition as something mystical or detached from the body, but intuition as sensory intelligence, the ability to feel what is true, safe, or supportive in the moment.
From a nervous system perspective, intuition happens when signals are clear, and the system is not stuck in survival mode.
Why regulation matters more than “fixing”
One of the most important shifts I’ve seen in nervous system work is moving away from the idea that something is broken. The enteric nervous system is not malfunctioning; rather, it is responding to the environment it’s been given. The signals from chronic stress, unresolved grief, lack of rhythmic input, and disconnection from bodily sensation are not faults but calls for care and attention. These elements affect how the ENS functions. Regulation doesn’t come from forcing change, but from providing the right conditions: safety, rhythm, and coherent sensory input.
When those conditions are present, the body does what it has always known how to do.
A more integrated view of health
Understanding the enteric nervous system invites us to think differently about well-being. Health is not only about nutrition, mindset, or exercise in isolation. It’s about communication between systems.
Gut health, fascial health, emotional management, and nervous system balance are not separate conversations, they are the same conversation, spoken through different tissues.
When we honor that interconnectedness, we move toward a model of care that is less about control and more about listening.
And sometimes, listening begins in the gut.
