I'm Aeryn O'Halloran, chronic illness survivor and certified mind/body practitioner. My work blends neuroscience, somatic practices, and polyvagal-informed education with my own lived experience of chronic illness and trauma. No quick fixes. No forcing. No pushing your system past its capacity. Just support, practical tools, and a path that honors your body's pace.

You’ll learn how stress patterns shape your physiology, how safety influences your biology, and how simple, repeatable practices can help your body shift out of survival mode and into a more balanced state. This approach blends trauma-informed neuroscience, somatic techniques, and holistic health principles with lived experience. Designed for sensitive bodies that need gentleness, clarity, and a realistic path forward.
The Resonant Body™ Approach
Sensory Modulation Techniques
ONE
Sensory modulation is especially important if you live with POTS/dysautonomia, ME/CFS, Lyme disease, MCAS, autoimmunity, anxiety disorders, or trauma-related challenges — all conditions where the nervous system becomes easily overwhelmed and reactive.
When sensory processing is dysregulated, your system stays stuck in survival mode, which can amplify symptoms like fatigue, dizziness, breathlessness, pain, nausea, overwhelm, and anxiety.

When sensory processing is dysregulated, your system stays stuck in survival mode, which can amplify symptoms like fatigue, dizziness, breathlessness, pain, nausea, overwhelm, and anxiety.
Sensory modulation techniques use gentle, specific inputs to help your body respond more appropriately, stabilize energy, reduce unnecessary activation, and strengthen the neural pathways that support healthy autonomic function. Over time, these techniques build flexibility, capacity, and resilience, allowing your system to respond to life with greater steadiness and less symptom reactivity.
Ultimately, sensory modulation supports long-term nervous system adaptability and healing, improving daily functioning and quality of life.

The Resonant Body™ Approach
Foundational Nutrition
Proper nourishment is especially supportive for people navigating chronic illness, dysautonomia, chronic fatigue, autoimmune conditions, or high inflammatory load. Your body needs consistent building blocks to support cellular processes, hormone regulation, immune resilience, and overall stability.
Foundational nutrition inside Resonant Body focuses on gentle nourishment that supports mitochondrial function, gut integrity, and reducing histamine or inflammatory load when needed.
You’ll learn simple principles that support steadier energy, clearer thinking, and a more supported system — without restriction or complicated protocols.

The Resonant Body™ Approach
Holistic Health Principles
Supporting chronic conditions requires a whole-body approach. Holistic health principles help regulate circadian rhythms, encourage more restorative sleep, support lymphatic and detox pathways, lower overall stress and inflammatory load, and align your lifestyle with your nervous system’s actual capacity.
Combined with nervous system work and foundational nutrition, these practices support a more sustainable, long-term path toward fewer flares, and a body that feels more regulated and resilient.

“I was having a massive range of symptoms like weight gain, pain, fatigue, brain fog, heart palpitations, panic attacks, etc and I decided I was completely over it. Aeryn gently guided me and gave me resource after resource on things to help and changes to make. Over the course of us working together it took a lot of dedication and patience but the results started to show up and stay. The storm has finally passed and I’m ready to take on life again.”

“Aeryn’s support has been out of this world. She was able to do more for me in one session than another practitioner was able to do in 8 months. Her approach is science based and comes from a place of deep understanding. I would recommend her program all day long to any one looking to better understand their patterns and nervous system.”

“Before working with Aeryn, my life was completely run by symptoms… I truly believed there wasn’t any hope for my recovery, as my doctors simply didn’t have any answers for me on how to improve. But after working with Aeryn, I noticed a difference. It was very slow at first, but within a few months I saw major improvement. I firmly believe that if I hadn’t found Aeryn when I did, I would still be in bed struggling to have energy to complete each day.”

The Foundations is my signature self-paced nervous system program for sensitive, overwhelmed, and chronically fatigued people who want to feel safe in their bodies again. This isn’t a quick fix. It’s a gentle, clinically informed rebuild of your relationship with your body — one that honors trauma, pacing, and the physiology behind chronic illness.
The Resonant Body Circle is a private messaging space where Foundations students can reach out for grounded guidance as they apply this work to daily life. You’re welcome to message as things arise, and I’ll respond during my weekday support hours with thoughtful, nervous-system-informed feedback. This is ongoing care, built around your real life with the flexibility to cancel anytime. Available exclusively to Foundations students.

Sensory modulation is the practice of using intentional sensory input, (touch, sound, rhythmic movement, breath, visual cues), to influence how your nervous system processes information. It gives your body alternative information to orient to, which can help reduce overwhelm and support a more regulated state..
These techniques aim to create neural pathways to encourage calming, organizing, and settling nervous system activation. Instead of forcing change, sensory modulation offers cues that help your system find a greater sense of balance and internal safety.
