| Published July 30, 2025 Big news – we got a Big Win! …DPC Now HSA-Approved, IRS-Backed, and Business-SmartIn a rare moment of legislative clarity, the recent One Big Beautiful Bill (technically H.R. 824 and its health provisions rider) delivered a major win for Direct Primary Care (DPC). Tucked between the usual flood of acronyms and legalese was a plainspoken truth: DPC isn’t “weird insurance.” We’re doctors. We’re care teams. We’re actual medical providers. And now, we’re finally recognized as such by the IRS. What this means for our patients: HSA (health savings accounts) money can now be used for monthly DPC membership fees—without any hand-wringing or fine-print loopholes. Before: Some HSAs allowed it, some didn’t, and the IRS shrugged.Now: We’re solidly in the “qualified medical expense” category. And bonus ! Employers can now write off DPC as a business expense, opening the door for companies (yes—even your brother-in-law’s plumbing company with 19 employees) to offer DPC as a health benefit.This allows small businesses to give better care at lower costs.It boosts continuity, cuts out middlemen, and supports doctors who know their patients.DPC was already an excellent model of care—now the tax code is catching up (after wandering aimlessly for a decade) Speaking of wandering…lets talk about The Wandering Wonder: Your Vagus Nerve Let’s pivot from policy to physiology. The vagus nerve (Latin vagus, meaning “wandering”) is the tenth cranial nerve and a true wanderer—it originates in the brainstem and winds through the neck, chest, and abdomen. Along the way, it touches your heart, lungs, diaphragm, stomach, intestines, and more. It’s the main highway of your parasympathetic nervous system—your rest, digest, recover, and restore system. What does it do? – Slows the heart rate -Stimulates digestion – Calms inflammation – Modulates mood and anxiety – Connects gut and brain in surprising ways And here’s the kicker: some researchers now believe Parkinson’s disease may begin in the gut, not the brain. A major Danish study found that people who had undergone a vagotomy (cutting of the vagus nerve) were significantly less likely to develop Parkinson’s later in life.The theory? Misfolded proteins in the gut travel up the vagus nerve into the brain, triggering a cascade of other proteins including alpha-synuclein to also misfold and thus cause neurodegeneration. This challenges the long-held belief that Parkinson’s is strictly a brain-based illness. It may be an “inside-out” disease—gut to nerve to brain. This fits with emerging models suggesting there is a very definitive gut brain axis – and that disease is often connected across systems. Gut health isn’t just about digestion—it may be shaping your long-term brain health, too. Can We Stimulate the Vagus Nerve to Heal? Yes—though as always in medicine, the details matter. Medical Devices: Vagal Nerve Stimulation (VNS) has been FDA-approved for over two decades for conditions like epilepsy and treatment-resistant depression. These are surgically implanted devices that send controlled electrical impulses to the vagus nerve in the neck. In many cases, they’ve reduced seizure frequency and improved mood in patients with otherwise unresponsive depression. Non-Invasive Options: More recently, researchers have explored transcutaneous VNS (tVNS)—a non-invasive approach using skin-surface electrodes, often applied near the ear (tragus or auricular branch) or on the side of the neck. Early studies suggest potential benefits for: – Anxiety and PTSD – Depression – Heart rate variability (HRV) – Inflammatory diseases (e.g., rheumatoid arthritis, Crohn’s) – Long COVID symptoms including brain fog and fatigue While still under investigation, these applications are promising—and unlike implants, they require no surgery. Consumer-Grade Devices You can now purchase vagus nerve stimulators online—ranging from ear-clip systems to handheld neck pulse devices, many marketed for stress relief, sleep, or mental clarity. But here’s the challenge: clinical-grade tVNS used in studies is very specific in frequency, pulse width, and placement. Consumer devices often lack that precision, and few have undergone independent testing. A 2022 review in Frontiers in Neurology noted that most commercial devices haven’t been validated in high-quality trials, making their claims hard to evaluate.Still, that doesn’t mean they’re useless—some patients report subjective improvements, and early-stage studies show that certain parameters (20–30 Hz, pulse widths of 250–500 microseconds, duty cycles with on-off intervals) can influence autonomic tone. In short: buyer beware, but also buyer curious. More robust research is needed before we can recommend one specific brand or model—but the field is moving fast. Natural Methods That May Boost Vagal Tone Beyond machines, many traditional practices appear to activate the vagus nerve through gentle, body-based inputs. These include: – Deep belly (diaphragmatic) breathing – Humming, chanting, or singing – Prayer and contemplative stillness – Cold exposure (showers, splash-face techniques) – Gentle neck massage – Yoga, tai chi, or slow movement practices – Expressing gratitude and engaging in heartfelt connection These methods are time-tested, free, and show promising links to parasympathetic activation. They’re not “alternative”—they’re foundational. What Does the Research Actually Say? A 2023 meta-analysis in Brain Stimulation concluded that transcutaneous VNS significantly improved heart rate variability (HRV)—an objective marker of nervous system balance and emotional resilience. Smaller trials have reported reductions in inflammatory markers, like TNF-alpha and IL-6, especially in chronic inflammatory and autoimmune conditions. But we need to be honest: – Results are often modest, and some people respond better than others – Placebo effects are strong, especially in mood-related conditions – The field is still young, with ongoing research into who benefits most—and why Still, this much is clear: the vagus nerve represents a measurable, biological link between body and brain, between spiritual peace and physiological healing.When patients tell me they feel better after breathing exercises, time in nature, or prayer—it may not be “just in their head.” It may be traveling the vagus nerve. Two Freedoms Worth Celebrating This month gives us reason to celebrate two kinds of freedom: 1. Financial and healthcare freedom Thanks to legislative change, your HSA now supports the DPC model—care that’s personal, accessible, and relationship-based. Small businesses can now partner with DPC in a tax-smart way. It’s a huge win for patients, families, and communities. 2. Physiological and spiritual freedom God designed your body with remarkable systems for rest and repair. The vagus nerve reminds us that healing often begins with peace, stillness, breath, connection, and gratitude. Dr. Jeff Ponke Forest Direct Primary Care |
