A cold exposure protocol is a tracking template for a planned series of cold showers, cold-water immersion sessions, or ice baths inside a defined review window. It is not a treatment plan and it is not a longevity guarantee; it is a way to log dose, timing, and recovery so the user can tell whether the practice changes their proxies in a readable way.
Why a protocol is needed
Cold exposure varies in temperature, duration, frequency, and timing relative to training and sleep. Without a written plan, every session is a slightly different stressor, and the readiness score or mood reading after each session is hard to compare. A protocol fixes the variables that can be fixed.
The pillar understanding dose windows and cycles is the closest match here, because cold exposure depends on the same logic of dose, window, and review block that a supplement cycle uses.
Proxy pair
The primary proxy is usually a subjective rating after the session and the next morning, such as perceived alertness, mood, or readiness. A secondary proxy might be an hrv baseline trend, resting heart rate trend, or sleep onset over the block.
The review does not require every proxy to improve. It asks whether the chosen markers moved together in a way the user finds worth the cost.
Limits of the claim
A cold exposure protocol does not claim to extend life, prevent disease, or replace medical care. Some users may log better perceived alertness after sessions; others may find that the stress cost is not worth the return. Both outcomes are valid results of a tracked block.
If cold exposure is added on top of heavy training, low sleep, or a new supplement, the review may not be able to attribute the change to cold alone.
How this appears in Unfair
In Unfair, a cold exposure protocol would prefill session logging, a same-day proxy, a next-morning proxy, and a fixed review date. Optional supplements added during the block would be flagged so the review does not credit cold for a stack change.
Clinical safety note
Cold immersion has safety considerations for people with heart conditions, uncontrolled hypertension, Raynaud's phenomenon, pregnancy, or certain medications. This glossary entry defines the logging concept and does not evaluate acute symptoms or protocol suitability.
