We measure our sleep, stack our supplements, and follow strict morning routines. Yet somehow, we are more anxious and more disconnected from ourselves than ever. Maybe the problem isn't that we're doing too little. Maybe it's that we're doing too much of the wrong things, and not enough of the oldest ones. "Our nervous system doesn't need more," organizational psychologist and neuroscience-based coach Julie Robinson said. "It needs less, and it needs better."
When the Nervous System Never Rests
When the nervous system is balanced, the body settles into rest-and-digest mode, and every system functions as it should. When it's activated, the body shifts into fight-or-flight, and the stress response pulls resources away from digestion, immunity, and repair toward immediate survival needs, licensed psychologist Jaz Robbins explained. The problem, according to integrative physician Priyal Modi, is that modern life often keeps that switch flipped long after the actual threat has passed. "Many people are living in a chronic state of survival without realizing it," Modi said.
The symptoms of that dysregulated state ripple across nearly every system: elevated heart rate and blood pressure, disrupted sleep, persistent fatigue, gut problems, difficulty concentrating, emotional reactivity, social withdrawal — sometimes accompanied by self-medicating with ultra-processed food, caffeine, or alcohol. One biological mechanism researchers point to is the vagus nerve's role in regulating inflammation: when the nervous system is well-regulated, production of pro-inflammatory cytokines decreases.
"Reducing a single symptom over the long term can be challenging when that symptom may be resting atop an activated, or overactivated, nervous system," Robbins said.
Ancient Answers, Modern Language
Neuroscience is now validating much of what ancient traditions have understood for thousands of years — that the state of the nervous system shapes how we think, feel, heal, relate, and function, Modi explained. Breathwork, meditation, mindfulness, chanting, yoga, prayer, time in nature, and mindful movement were designed as ways to regulate the nervous system and cultivate balance. "What neuroscience now offers is the language and physiology behind these practices," she said.
Mindfulness-Based Stress Reduction (MBSR), now used in hospitals and clinics worldwide, was developed by Jon Kabat-Zinn in 1979 — drawing explicitly from contemplative traditions in early Buddhism dating back roughly 2,500 years. The practice didn't change. The framing did. Regular meditators exhibit higher levels of GABA, a neurotransmitter associated with calming the nervous system, along with lower cortisol and measurable improvements in nervous system flexibility over time.
"Interestingly, ancient wisdom traditions and modern approaches to nervous system regulation often share remarkably similar practices: meditation, breathwork, rhythm, movement, social connection, and time in nature," certified mindfulness teacher Dr. Lilian Cabiron added. The key difference lies in interpretation — ancient traditions often viewed these practices as pathways to spiritual balance and wisdom, while modern approaches explain them through neuroscience and stress physiology.
Back to Basics: The Regulator No App Can Replace
"What I keep returning to, both in my own life and in the work I do with people, is that the basics are foundational, and most of us have abandoned them in pursuit of something more sophisticated, measurable, and impressive," Robinson said. Because they seem simple, many people dismiss them as insufficient. "However, they are the solid ground everything else is built on, and when we skip past them in search of the next trend, we are building on the fragility of sand."
Robinson points to something missing from most conversations about wellness optimization: nervous system regulation has become a solitary pursuit, managed through apps and individual protocols, while overlooking the most powerful regulator of all — human connection. "We settle our nervous systems in the company of people who feel safe to us," she said. "We resource one another, and we are renewed by connection in ways that no protocol can replicate."
What Regulation Actually Looks Like
Kari Asadorian, a registered nurse with a background in neurology and psychiatry, sees this play out daily in her school nurse's office. When a student is too overwhelmed to speak, she doesn't reach for a checklist — she asks them to place a hand on their belly and notice their breath. "As a school nurse, I see dysregulated students who need tools to help them calm down so they can socialize with peers and perform at an optimal learning state in the classroom," Asadorian said.
Her tools are simple and old: guided breathing, grounding techniques, sensory awareness. One example is the 5-4-3-2-1 method — identifying five things you can see, four you can touch, three you can hear, two you can smell, and one you can taste — which anchors a racing mind back to the present moment. Stretching, dancing, walking, and humming may also help stimulate the vagus nerve and support a shift toward a parasympathetic, rest-and-digest state.
"Stress is part of everyday life," Asadorian said. What matters is what you do during those shifts, and finding what actually works for you — consistency over intensity is central to nearly everything experts in this space recommend.
Regulation Isn't Just Rest — It's Flexibility
Nervous system care isn't only about calm. Healthy challenge, purpose, play, creativity, laughter, and emotional connection are equally regulating for the human system, Modi noted. "A healthy nervous system is flexible," she said. "It allows activation when needed and a return to rest afterward. This adaptability is what regulation really means."
Perhaps what modern science is increasingly showing us isn't something entirely new, but rather a new language for principles that have shaped human wellbeing for thousands of years. The tools were never missing. We just needed the research to catch up to what contemplative traditions already knew.
