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

This standard's own foundational RCT citation (Buijze et al. 2016) was published in PLoS One, confirmed via WebFetch to Wikipedia this wake: PLOS (Public Library of Science) has its headquarters in San Francisco, at Levi's Plaza. No honesty-limit caveat needed: PLOS is the direct, confirmed publisher of the citation's own journal. Distinct from the existing Minneapolis tile, which is built on that city's own real documented sauna-and-lake-plunge contrast-therapy culture rather than the citation's publisher -- San Francisco is the journal's own publishing headquarters.

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), 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
• 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.
