Evidence Library · AXIOM SELENE
Verified Wellness Research
Long-form reviews of the evidence behind wellness modalities. Every factual claim carries a citable source. Every gap is named explicitly rather than filled with confident-sounding substitutes. Provenance is visible — not buried in footnotes, not absent.
How every article here works
Each article carries per-claim sourcing (real URL + evidence tier), a last-verified date, and an explicit What We Don't Know section. We do not invent sources. If we cannot find a real source for a claim, we omit the claim.
Evidence tiers: 🅰 Primary — peer-reviewed journals, official registries · 🅱 Secondary — established medical organisations, Cochrane, established press summarising research · 🅲 Weak — provider claims, single blog (always hedged; never used as a standalone factual source).
Breathwork & Nervous System
Preliminary evidence
Breathwork & the Wim Hof Method — What's Actually Proven
A 2014 PNAS study (n=12 trained men) showed practitioners can voluntarily suppress inflammatory cytokines — compelling but small. A 2024 RCT found WHM no better than slow breathing for depression. Mood benefits are real but short-term. Breath-holds near water have caused drowning deaths. Here is what the science actually shows.

Recovery & Cold Therapy
Preliminary evidence
Cold Water Immersion for Mood and Mental Health: What the Evidence Shows
Research shows a single cold immersion can lift acute mood, but the only dedicated randomised controlled trial (2024, n=84) found cold showers did not outperform warm ones for depression. The evidence is early-stage, honest about its limitations, and more nuanced than most wellness content suggests.

Recovery & Cold Therapy
Moderate evidence
Cold Plunge: What the Evidence Actually Shows
A 2025 systematic review of 3,177 participants found real benefits for sleep quality and noted a reduction in sick-day absences — but found no immune effect and cautioned that benefits may be short-lived. Here is what the research says, and what it does not.

Mindfulness & Sensory Therapies
Preliminary evidence
Float Tanks (Sensory Deprivation / REST) — What the Evidence Actually Shows
A 2025 systematic review of 63 studies found consistent signals for stress and anxiety reduction — but the most rigorous chronic pain trial found no long-term benefit over placebo, sleep evidence is limited, and most anxiety research comes from a single research group. Here is what the science shows, and what it does not yet confirm.

Oxygen & Pressure Therapies
Preliminary evidence
Hyperbaric Oxygen Therapy for Wellness: What the Evidence Actually Shows
HBOT has a strong evidence base for specific acute and chronic medical conditions — decompression sickness, carbon monoxide poisoning, non-healing wounds. Its use for anti-aging, longevity, and general wellness rests almost entirely on one small Israeli study with no control group. Here is the honest picture.

Heat Therapy & Longevity
Preliminary evidence
Infrared Sauna vs Traditional Sauna: What the Evidence Actually Says
Both types of sauna generate heat and induce sweating — but they work via different mechanisms, operate at very different temperatures, and have almost entirely separate bodies of research. A 2018 systematic review of 3,855 participants concluded there is currently not enough evidence to distinguish any particular health differences between the two. Here is what is actually established, and where the evidence runs out.

Nutrition & Metabolic Health
Moderate evidence
Intermittent Fasting: What's Proven, What's Overstated, and What We Don't Know
Intermittent fasting reduces weight and improves some metabolic markers — but so does standard calorie restriction. Here is what the controlled trials actually show, where the hype outruns the evidence, and who should be careful.

Nutrition & Supplementation
Moderate evidence
Magnesium Supplements: Proven vs. Overhyped
Magnesium is the fourth most abundant mineral in the body and genuinely important — but most of the measurable benefits appear in people who are actually deficient. Here is what the peer-reviewed evidence shows across seven common claims, and where the marketing has run far ahead of the science.

Recovery & Massage Therapy
Moderate evidence
Massage Therapy & Recovery: The Evidence (Including Thai Massage)
Massage has good evidence for reducing post-exercise muscle soreness and short-term pain relief. Thai massage specifically has promising trial data for pain and flexibility. But popular claims — 'flushes lactic acid', 'detoxes the body' — are either false or unsupported. Here is what the research actually shows.

Mindfulness & Stress Science
Moderate evidence
Meditation & Stress: What the Evidence Actually Shows
Mindfulness meditation has moderate evidence for reducing anxiety and depression. The cortisol picture is more complicated: 71% of studies find reductions, but effect sizes are likely small, study quality is inconsistent, and many wellness claims go further than the data warrant. Here is an honest read of where the science stands.

Longevity & IV Therapy
Preliminary evidence
NAD+ and IV Vitamin Therapy: What the Science Actually Shows (and Doesn't)
The marketing is enormous — clinics promise restored energy, cellular rejuvenation, and longevity. The human evidence, read carefully, is thin. Here is what is genuinely known, what remains uncertain, and which specific claims have no credible scientific support.

Moderate evidence
Red Light Therapy (Photobiomodulation): What the Evidence Actually Shows
A 2025 umbrella review of 204 randomised trials found real — if modest — benefits for specific pain conditions and skin texture, but zero high-certainty evidence for any application. Here is an honest tour of what the research confirms, what it only suggests, and what remains unproven.

Preliminary evidence
Sauna & Longevity: What the Finnish Data Shows (and What It Doesn't)
A 20-year Finnish observational study found a striking association between frequent sauna use and lower cardiovascular mortality. But this is observational data — not a controlled trial. Here is what we can and cannot conclude, and what remains unanswered.

Sleep Optimization: Evidence-Based Fundamentals (and What the Marketing Gets Wrong)
CBT-I has strong RCT evidence for insomnia. Consistent sleep timing and adequate duration have solid observational backing. Many marketed sleep gadgets and supplements do not. Here is what the research actually supports — and where the honest gaps remain.

Mind-Body Practice
Moderate evidence
Yoga for Stress and Flexibility: What the Evidence Actually Shows
Multiple systematic reviews confirm yoga produces modest, statistically significant reductions in self-reported stress and anxiety compared to doing nothing — and Cochrane data supports it for chronic low back pain. But evidence quality is rated 'low' for most outcomes, and claimed benefits are more modest than popular accounts suggest.
