For millions of people scrolling through TikTok or Instagram, the symptoms feel all too familiar: a racing heart, a tight chest, chronic digestive issues, or a baseline of anxiety that never seems to lift. In the last year, a wave of content has surged across these platforms, offering a seductive explanation for these feelings. The diagnosis? A “dysregulated nervous system.”
The videos, often produced by well-meaning creators in their living rooms, promise a “reset.” They suggest that through a specific sequence of humming, chest-tapping, weighted blankets, or ear massages, you can manually override your body’s stress response and return to a state of calm. While some of these grounding exercises can provide temporary relief, medical experts warn that the narrative being sold online often simplifies complex biology into pseudoscientific shortcuts.
As a physician, I have seen how the allure of a “quick fix” grows when people feel overwhelmed by a world that feels increasingly unstable. But understanding nervous system dysregulation requires moving beyond a 60-second clip. True regulation is not a button you press; This proves a lifelong interplay between your biology, your history, and your environment.
The Biology of Balance: Sympathetic vs. Parasympathetic
To understand why these online trends are so appealing, it is first necessary to understand what the nervous system actually does. According to Ciaran Murphy-Royal, an associate professor in the Department of Neuroscience at the Université de Montréal and principal investigator at the Murphy-Royal Lab at the CHUM, the nervous system is essentially the body’s primary communication network.
It is divided into the central nervous system—the brain and spinal cord—and the peripheral nervous system, which consists of the nerves that reach every corner of the body. Within this network, two primary states govern our physiological response to the world: the sympathetic and the parasympathetic systems.
- The Sympathetic Nervous System: This is the “fight or flight” mode. It releases stress hormones, accelerates heart rate and breathing, dilates pupils, and increases muscle strength to facilitate us survive a crisis. Simultaneously, it shuts down non-essential functions, such as digestion.
- The Parasympathetic Nervous System: This is the “rest and digest” mode. It slows the heart rate, lowers breathing, and stimulates autonomous processes like digestion, allowing the body to recover and maintain itself.
Dysregulation occurs when the response of the nervous system is inappropriate for the current circumstances. This can manifest in two directions: a hyper-response, where a minor stressor triggers a full-blown panic attack, or a hypo-response, where the system “shuts down” during a dangerous situation, leaving the individual without the energy or motivation to respond.
However, Murphy-Royal emphasizes that regulation is not a binary “on or off” switch. “We expose just the black and white, but in fact, everything is in the gray zones,” he notes. Most people who can function in daily life—eating, moving, and thinking normally—are already largely regulated, though everyone operates on a different baseline of resilience shaped by their early life and environment.
The Weight of the World: Allostatic Load
Medical science recognizes that not everyone starts from the same baseline. The risk of dysregulation is often tied to a concept known as “allostatic load”—the cumulative physiological wear and tear on the body and brain resulting from chronic exposure to stress.
Kafui Sawyer, a psychotherapist and director of the Joy Health & Research Center in Ottawa, explains that this load is not distributed equally. Individuals who have experienced childhood abuse, poverty, or systemic racism accumulate a higher allostatic load. For example, repeated racial microaggressions trigger a persistent “fight or flight” response, which can lead to long-term issues with blood pressure and sleep.
Sawyer, who also serves as a consultant for Health Canada, points out that the current global climate—marked by environmental instability and social injustice—amplifies this load for nearly everyone. When people realize they do not live in a secure or just world, the resulting feeling of loss of control manifests as chronic anxiety.
Debunking the ‘Vagus Nerve Reset’
This widespread anxiety has created a market for “nervous system hacks.” Many of these videos focus on the vagus nerve, the longest nerve in the body, claiming that massaging the neck or the ear can “reset” the system.
@docbeckyck Most people don’t realize this… The upper ear is directly connected to the vagus nerve. Slow circular massage here for 2 minutes sends safety signals to your nervous system, helping ease stress, tension, anxiety, and that “on edge” feeling. No tools. No supplements. Just your body remembering how to regulate itself. If your system has forgotten what calm feels like, this is your reminder. ✨ This is just one of many nervous-system-based healing practices inside Harmonic Healing—where regulation becomes your recent baseline, not a rare moment. 👉🏻 If this landed in your body, you’ll feel at home inside the course.

While grounding techniques like deep breathing or gentle tapping can be helpful because they bring a person back into the present moment, Murphy-Royal is skeptical of claims that one can “restart” the nervous system through external nerve stimulation. “I would not massage my nerves too much, because I would not want to damage them. They are very fragile structures,” he warns.
He notes that while a massage can be relaxing, there is no clinical evidence supporting a specific “activation system” for the vagus nerve that can be triggered by simple rubbing or the use of vibrating consumer tools. When a creator claims to have found a “miracle solution” or a complete understanding of these complex pathways, it is often a red flag for pseudoscience.
Evidence-Based Paths to Regulation
For those struggling with chronic anxiety or trauma, science recommends more robust, structured interventions than social media hacks. Depending on the severity, these may include pharmacological options or specialized therapies:
- Cognitive Behavioral Therapy (CBT): A gold-standard approach that helps individuals recognize the relationship between their thoughts, emotions, and behaviors to regain a sense of control.
- EMDR (Eye Movement Desensitization and Reprocessing): An evidence-based treatment for trauma that uses bilateral sensory stimulation to reduce the emotional intensity of painful memories.
- Somatic Therapies: These approaches explore the connection between the body and the mind, acknowledging that trauma is often “stored” physically.
Sawyer emphasizes that for marginalized communities, these therapies must be culturally adapted and anti-racist to be effective. However, she argues that individual clinical care is only one piece of the puzzle.
The most critical factor in healing a dysregulated system is often social connection. “The nervous system does not heal in isolation,” Sawyer says. “In fact, it regulates most effectively within safe and just spaces where the dignity of individuals is respected.”
Healing requires a combination of individual therapy and the reintegration into a supportive community. Replacing negative experiences with positive ones in environments where a person feels welcome is essential for long-term recovery. This means that addressing systemic inequalities—such as lack of access to healthcare and the legacies of colonization—is not just a political goal, but a public health necessity.

As research into the gut-brain axis and the vagus nerve continues to evolve, the medical community expects more nuanced data on how we can support the nervous system. The next frontier of this research will likely focus on the intersection of social determinants of health and biological resilience, moving the conversation away from “hacks” and toward systemic wellness.
