Cold shower / cold-water exposure protocol audit + progression — Minneapolis.

Minneapolis carries a real, documented contrast-therapy culture, not an imported trend: the 612 Sauna Cooperative, founded by John Pederson in 2016 as America's first member-owned sauna co-op (over 150 members), grew from a backyard wood-fired sauna into 'the Forge,' the country's first community-owned mobile sauna, funded by a 2016 Kickstarter that raised nearly $34,000 from 233 backers. Cold plunges in the city's own lakes (Silver Lake, Lake Nokomis, Cedar Lake) have been part of the practice from the start, following the traditional Finnish pairing of sauna heat with a cold-water dip. This tile pairs directly with this library's own Minneapolis sauna def on the same city, the same way the practice is actually done — heat then cold, not one without the other — while keeping the RCT's real, narrower finding (less sickness absence, not fewer illness days) as the honest claim.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash — recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof

Contraindication screen + current cold-exposure pattern log (method, temperature/duration, frequency) + a conservative progression plan (short/warm before long/cold) + explicit statement that the practice targets sickness-absence/tolerance, never illness frequency, with any symptom routed to a clinician

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

• cold-exposure access log (method, water temperature, duration, sessions/week)
• a thermometer if precise water temperature is tracked (optional but recommended)
• a contraindication screen (PAR-Q+ or clinician clearance note)
• clock/timer
• a warm space and towel nearby for immediate re-warming

Steps

1. 1. Screen for contraindications FIRST: uncontrolled hypertension, arrhythmia history, recent cardiac event, Raynaud's phenomenon, cold urticaria, uncontrolled asthma, or pregnancy. Anyone flagged is routed to a clinician for clearance before any progression — do not proceed.
2. 2. Record the current pattern: method (cold shower tail-end vs. dedicated cold-water immersion), water temperature (if known), duration, and sessions per week.
3. 3. Compare to the trial protocol (Buijze 2016: hot-to-cold shower, building to 30-90 seconds of cold, daily) and note the gap as a coached goal, not a prescription.
4. 4. Set a conservative progression: start with a brief cold finish to a warm shower (10-15 seconds), extend duration gradually before increasing frequency; never start with full cold-water immersion or an unsupervised open-water plunge.
5. 5. State the honest claim explicitly in the record: the evidence supports reduced sickness ABSENCE from work, not reduced illness frequency — the person will still get sick as often; frame the goal as tolerance/resilience, never immune enhancement.
6. 6. If a session is observed, watch for the cold shock response (involuntary gasp, hyperventilation, panic) and stop immediately if it occurs; never leave a first-time cold-water-immersion attempt unsupervised.
7. 7. Record the log, the progression plan, and the contraindication-screen result; sign. Route any red flag to a clinician.

What counts as done

• Completed contraindication screen (cleared, or routed to a clinician)
• Current pattern logged: method (cold shower vs. cold-water immersion, including open-lake plunges), water temperature, duration, frequency per week
• A conservative progression plan (shorter/warmer before longer/colder) with an explicit no-cannonball-on-day-one rule and a clear exit plan for cold-shock symptoms
• Any open-water/lake plunge confirmed done with a companion present, never solo, per the cold-shock drowning risk
• The claim framed honestly: reduced sickness absence/symptom tolerance per the RCT evidence, NEVER framed as reducing how often the person gets sick

Proof is measured against these, not judged by taste.
