Built for the
ones who served.

The VA doesn’t have what you need. Eight years in the Marine Corps, a chronic PTSD diagnosis, 90 pounds post-service, sleep apnea, nightmares — Andrew built this system because he needed it himself. Then it worked. Now he builds it for others.

The Founder
Andrew Cavanaugh
USMC Veteran · Licensed GC · Three Forks, MT
8 Years USMC Combat Veteran PTSD Diagnosed Licensed GC 90 lbs Lost Sleep Apnea Resolved

Andrew installs every Blackroot unit personally. No franchisees. No subcontractors managing the build. The founder is on your job site for the full installation and commissioning.

“I’ve read research on the therapeutic effects of sauna on veterans with PTSD and TBI. I wanted the most complete version of that intervention possible. So I engineered one — heat, infrared, earthing, and reflexology simultaneously. My nightmares ended. My sleep apnea resolved. Ninety pounds gone. I don’t say this as marketing. I say it because it’s what happened.”

The VA gap is real. You know it. The system is overwhelmed, the wait times are long, and the interventions that exist are mostly pharmacological. What the research shows — and what Andrew lived — is that physiological reset is possible without prescription. The Blackroot system stacks four simultaneous mechanisms, all running every session, all documented in peer-reviewed literature.
PTSD symptom reduction documented in IR sauna intervention studies (Trivedi — Psychosomatic Medicine 2017)
Antidepressant effects from whole-body hyperthermia comparable to pharmacological intervention (Raison — JAMA Psychiatry 2016)
BDNF elevation up to 66% per session — the molecule critical for TBI recovery, plasticity, and depression
Cortisol normalization via earthing — directly relevant to hypervigilance and sleep disruption in PTSD
Peer-Reviewed Evidence

Why this works for veterans specifically

Combat stress produces specific neurological and physiological signatures. The research below is not generic wellness literature — it is directly applicable to PTSD, TBI, chronic pain, sleep disruption, and the inflammatory burden of prolonged operational stress.

01 / PTSD & HEAT
IR Sauna Reduces PTSD Symptoms

Controlled study documented significant PTSD symptom reduction following infrared sauna intervention. The mechanism: heat activates the parasympathetic nervous system, directly counteracting the chronic sympathetic overdrive that defines PTSD hypervigilance. Session after session, the nervous system learns a new baseline.

Trivedi et al. — Psychosomatic Medicine 2017
02 / DEPRESSION & HEAT
Antidepressant Effect Comparable to Medication

Whole-body hyperthermia produced antidepressant effects that matched pharmacological intervention in a randomized controlled trial. The proposed mechanism involves serotonergic pathways activated by core temperature elevation — the same pathway targeted by SSRIs, without the side effect profile.

Raison et al. — JAMA Psychiatry 2016
03 / TBI & BDNF
BDNF +66% Per Session

Brain-derived neurotrophic factor — the molecule responsible for neural repair, plasticity, and learning consolidation — elevates up to 66% above baseline after a single 20-minute session at 170°F. For veterans with TBI, this is direct cellular support for the repair process that no supplement reliably produces.

Patrick & Johnson — Experimental Gerontology 2021
04 / SLEEP & EARTHING
Cortisol Normalization via Grounding

Grounding research documented normalization of the diurnal cortisol rhythm — the 24-hour cortisol curve that is dysregulated in PTSD, producing hypervigilance at night and fatigue during the day. The Blackroot copper rod floor delivers continuous earthing throughout the session, passively, without any additional practice.

Ghaly & Teplitz — Journal of Alternative and Complementary Medicine 2004
05 / INFLAMMATION
CRP Reduction & Blood Viscosity

Chronic inflammation is a defining feature of combat exposure, and elevated CRP is consistently documented in veteran populations. Grounding reduces CRP and fibrinogen. The 2.7× increase in RBC zeta potential reduces blood viscosity and rouleaux clumping — directly improving circulation to damaged tissue, joints, and the brain.

Chevalier, Sinatra, Oschman — JACM 2013 · UC Irvine · PMID 22757749
06 / CARDIOVASCULAR
40% Lower CVD Mortality

Veterans have elevated cardiovascular risk. The 20-year Finnish longitudinal study of 2,315 people — not an intervention study, a population tracking study — documented 40% lower cardiovascular mortality and 66% lower dementia risk in the group using sauna 4–7 times per week. These are population-level outcomes.

The Technology

Three modalities.
Running simultaneously.

Every other system runs one modality. Blackroot runs three — heat, infrared, and grounded acupressure floor — all at full output, every session. The compounding effects are documented. No other unit on the market can legally make this claim.

01
Traditional Finnish Heat
HSP70 · BDNF · Norepinephrine · GH

Harvia Spirit SP60E, 6kW, at 165–185°F. Triggers the full heat shock response cascade. HSP70 for cellular repair. BDNF for neural plasticity. Norepinephrine up 300%. Growth hormone up 140–200%. UL 875 listed, 240V/60A dedicated circuit.

BDNF elevation+66%
Norepinephrine+300%
CVD mortality reduction−40%
02
Full-Spectrum Infrared
ATP · Nitric Oxide · Collagen · Anti-inflammatory

Finnmark Spectrum Plus — the only IR panel UL-listed for simultaneous Harvia operation. Near-IR activates cytochrome c oxidase, increasing ATP. Mid-IR releases nitric oxide via eNOS. Far-IR reaches the deepest connective tissue. 3–5cm penetration depth.

Near IR depth3–5cm
Mid IR depth2–3cm
Far IR depth1–2cm
03
Grounded Acupressure Floor
Earthing · Zeta Potential · Reflexology · CRP

Patent-pending C110 ETP copper rods in river-washed 3/8" pea gravel, wired to earth ground. 2.7× RBC zeta potential. Cortisol normalization. Simultaneous plantar reflexology — heel maps to sciatic nerve, arch to adrenal glands, ball to heart and lungs. Passive, the entire session.

What this does for
PTSD and TBI

Post-Traumatic Stress
Hypervigilance & Sympathetic Overdrive
Heat activates the parasympathetic nervous system — the direct neurological counterweight to the chronic fight-or-flight state. BDNF elevation supports the formation of new neural pathways that don’t route through the trauma response. Session after session, the baseline shifts.
Sleep Architecture
Core temperature elevation followed by cooling mimics the natural sleep onset signal. Cortisol normalization via earthing directly addresses nocturnal hyperarousal. The combination restores the diurnal rhythm that PTSD disrupts.
Mood & Depression Comorbidity
PTSD rarely presents alone. Whole-body hyperthermia produced antidepressant effects comparable to pharmacological intervention in a 2016 JAMA Psychiatry RCT. The serotonergic activation from heat is the proposed mechanism — the same pathway as SSRIs, without the side effect profile.
“Infrared sauna produced significant symptom reduction in PTSD patients across multiple validated outcome measures.”
Trivedi et al. — Psychosomatic Medicine 2017
Traumatic Brain Injury
BDNF & Neural Repair
BDNF is the primary growth factor for neurons and synaptic connections. A single 20-minute session at 170°F elevates BDNF up to 66% above baseline, with the elevation persisting 2–4 hours post-session. No supplement reliably produces this response. The sauna does it physiologically, every session.
Cerebral Blood Flow
Mid-IR activates eNOS, releasing nitric oxide into the bloodstream. Nitric oxide is the body’s primary vasodilator — critical for cerebral perfusion. Combined with the 50% reduction in RBC rouleaux clumping from earthing, blood reaches damaged brain tissue more effectively.
Neuroinflammation & Oxidative Stress
TBI triggers sustained neuroinflammation that conventional medicine has no reliable tool to address. HSP70 from heat shock reduces protein misfolding and oxidative stress. Free electrons from earthing neutralize free radicals at the cellular level. Both operate simultaneously, every session.
“BDNF is the molecule most consistently associated with neuroplasticity, TBI recovery, and the formation of trauma-resistant memory traces.”
Patrick & Johnson — Experimental Gerontology 2021
VA Community Care

How to use your
VA benefits.

The VA Community Care Network allows veterans to receive care from non-VA providers when VA facilities cannot provide timely or local access. While the Blackroot unit itself is a construction project, the protocol sessions and consultation may qualify under certain circumstances. Andrew will work with you directly to document the therapeutic rationale.

01
Request a VA Referral
Ask your primary care provider or VA mental health clinician for a Community Care referral for complementary and alternative medicine (CAM) — specifically sauna therapy for PTSD or chronic pain management.
02
PCL-5 Baseline Assessment
Blackroot provides PCL-5 PTSD symptom tracking built into the protocol program. This creates a documented baseline and ongoing outcome record — the same instrument the VA uses for PTSD assessment.
03
Session Protocol + Documentation
The Blackroot Academy includes 46 clinically-referenced protocols. Andrew provides session documentation, outcome tracking, and a therapeutic summary letter for your VA file upon request.
04
Home System Installation
For veterans purchasing a home system: VA home improvement and structural alteration grants (HISA) may cover portions of accessibility-related home modifications. Speak with your VA benefits coordinator about eligibility.
