If You Want To Change Your Thoughts, Should You Include The Body?
For decades, mental health treatment has centered on the brain—changing thought patterns, reframing beliefs, and altering cognition to address mental and emotional challenges. While this approach has its merits, groundbreaking research from 2022-2024 suggests a more nuanced truth: the brain may not be the sole driver of our emotions, but instead part of a complex feedback loop with the body. To truly understand and support mental health, we must look beyond the brain as a standalone problem-solver and consider how the entire body shapes our emotional and psychological states.
The Brain as a Processor, Not the Problem
Emerging evidence highlights the brain’s role as a processor of information relayed by the body rather than the sole originator of thoughts and feelings. Interoception, the ability to sense internal bodily states like heartbeat, muscle tension, and gut activity, has been shown to profoundly influence emotions and perceptions. A 2024 study published in Nature Mental Health found that disruptions in interoceptive pathways were linked with increased vulnerability to mental health disorders such as anxiety and depression. This study underscores that the brain’s emotional response is deeply intertwined with signals from the body, challenging the traditional view that emotions are primarily cognitive. (ucl.ac.uk)
The Nervous System’s Silent Influence
According to Polyvagal Theory, developed by Dr. Stephen Porges, the autonomic nervous system (ANS) serves as the body's emotional regulator. The ANS constantly assesses internal and external environments for safety, using physiological cues—such as heart rate, respiratory rhythm, and gut activity—to determine whether the body should be in a state of calm or defense. This subconscious evaluation, termed neuroception, often dictates emotional responses before we are consciously aware of them.
What does this mean for mental health? It suggests that conditions like anxiety and depression may often stem from dysregulation in the body rather than purely maladaptive thought patterns. Instead of simply addressing the brain, interventions that target the nervous system—such as vagal nerve stimulation, breathwork, or body-based practices—can effectively shift emotional states. A 2023 study from Washington University School of Medicine found that brain regions responsible for higher-order cognition are deeply connected to networks regulating involuntary functions like heart rate and blood pressure, reinforcing the idea that emotional dysregulation often begins in the body.

The Gut-Brain Axis: Mental Health’s Hidden Key
The gut, often called the “second brain,” further illustrates the body’s impact on mental health. The gut-brain axis is a communication highway linking the digestive system and the brain via the vagus nerve. This connection explains why imbalances in gut health—such as inflammation or an unhealthy microbiome—can influence mood and even contribute to mental health disorders. Recent findings published in 2023 revealed that gut bacteria directly produce neurotransmitters like serotonin, which plays a key role in mood regulation. Disturbances in gut health have been correlated with conditions like depression, anxiety, and cognitive dysfunction, suggesting that effective mental health care must also address digestive health.

Yoga: A Pathway to Emotional Regulation
If the brain processes signals from the body, then practices that regulate the body can be essential for mental well-being. Yoga, long recognized for its holistic benefits, has emerged as a powerful tool for emotional regulation. More than just physical exercise, yoga combines movement, breathwork, and mindfulness, directly targeting the nervous system and promoting interoceptive awareness.
A 2020 study published in Frontiers in Psychiatry found that yoga breathing practices (pranayama) significantly improve autonomic nervous system balance, reducing symptoms of anxiety and enhancing emotional regulation. Moreover, yoga enhances interoceptive awareness, teaching individuals to recognize and respond to bodily cues with greater skill. For individuals recovering from trauma, this ability to reconnect with their bodies can be transformative, fostering safety and emotional stability where disconnection once dominated.

Moving Beyond “Mind Over Matter”
The idea of “mind over matter” has shaped how many professionals approach mental health, yet this concept is incomplete. The mind cannot be fully understood or healed without addressing the intricate web of signals flowing between the brain and body. By integrating approaches that regulate the nervous system, nurture gut health, and enhance interoceptive awareness, we create a more comprehensive framework for mental well-being.
For professionals working in the fields of mental health, somatics, body based emotions, or trauma recovery, the implications are clear: addressing mental health requires a whole-body approach. By expanding our focus beyond the brain, we can better support our clients in achieving lasting emotional balance and resilience.
It’s time to redefine the conversation—not as brain versus body, but as brain and body working together as one interconnected system.
