The rule treats tracking as temporary instrumentation rather than a permanent lifestyle. Begin with a specific health question instead of searching indiscriminately for problems. Collect a bounded set of relevant data for a defined period, and interpret those numbers alongside how you actually feel. Use the combination to choose concrete protocol or behavior changes. Once feedback has become intuitive and the original question is answered, simplify and drop the tracker. Continued measurement remains reasonable for someone who genuinely enjoys it and experiences no stress or shame, or when a clinician requires it. The decision criterion is therefore functional: keep measuring while the information changes useful decisions; stop when it mainly consumes attention, creates anxiety or repeats what you already know.
Origin
Dr. Will Cole explained how his clinic uses wearables and other health data for specific periods rather than indefinitely.
Core principles
- 01Tracking needs a specific question
- 02Data must be interpreted with lived experience
- 03Measurements should lead to action
- 04Optimization should simplify life
- 05Enthusiasm can justify ongoing tracking; shame cannot
How to run it
- 1
Name the question
State the health or behavior question the data should answer. Avoid tracking merely to discover more things to optimize.
Pro tip Phrase the question so a result could change a decision.
Watch out A vague goal such as “be healthier” invites endless measurement.
- 2
Bound the measurement
Choose the minimum metrics and a specific collection period. Keep the burden proportionate to the question.
Pro tip Decide the review date before collecting the first data point.
Watch out Do not turn tracking itself into the intervention.
- 3
Add lived context
Compare measurements with energy, mood, sleep and other relevant experience. Numbers without context can mislead.
Pro tip Use one short subjective note beside each day's data.
Watch out Do not dismiss concerning symptoms because a device score looks good.
- 4
Make an action step
Use the interpreted pattern to choose a concrete protocol or behavior change. If the data cannot affect action, reconsider collecting it.
Pro tip Change one or two variables first so the feedback remains legible.
Watch out Clinical decisions should be made with qualified guidance.
- 5
Drop or deliberately keep
Stop tracking once it has answered the question and the feedback is intuitive. Continue only when it remains useful, required or genuinely enjoyable without stress.
Pro tip Archive the conclusion so you do not restart the same investigation unnecessarily.
Watch out Do not stop monitoring that a clinician has told you is medically necessary.
In the wild
A person uses a wearable for three weeks to compare sleep scores with morning energy and a consistent bedtime change. Once the pattern is clear and the routine becomes intuitive, they stop checking the score every morning. They retain the behavior without retaining the daily anxiety-producing dashboard.
→ A bounded measurement produces a useful routine and then gives attention back.
Common mistakes
Looking for problems without a question
Open-ended optimization can create anxiety while producing little decision value.
Keeping the dashboard after learning
When the data no longer changes action, continued tracking can become noise or shame.
Is it for you?
Best for
It is best for people using wearables or logs to investigate a specific health issue or behavior.
Not ideal for
It is not ideal when continuous monitoring is medically required or genuinely enjoyable and harmless.
From the transcript
“we have them do it for specific periods of time”
“let's learn and get some data points for you and put it in context with how you're feeling and can we make action steps”
“and then drop it if you're truly like a biohacker and some people just really get excited about it and it's not a source of…”
