Method guide
What should you actually log in a symptom journal?
Three things, every day: how the symptom felt (1–5), what changed in your day, and one context note. Anything more and most people quit by day five.
The three-field rule
Most symptom journals fail because they ask for too much. A daily entry that takes more than sixty seconds will get skipped within a week. Limit yourself to three fields and you'll still surface meaningful patterns over [a 14-day tracking window](resource:how-long-to-track-symptoms-to-find-a-pattern).
What each field is actually doing
Each field plays a different role: a number gives you something to compare across days, a context note captures what was different, and a free-form line gives future-you the story behind the data.
- Symptom intensity (1–5): a single number you can scan across two weeks.
- What changed today: sleep, stress, schedule, environment — anything out of the ordinary.
- One free-form note: the sentence you'd want to read back on day 14.
What to deliberately leave out
Resist the urge to log everything. Skip vitals, detailed meal breakdowns, and anything you can't recall reliably. The goal is a sustainable signal, not a perfect record.
When to add a fourth or fifth field
Only add a new field once a candidate pattern has emerged. If you suspect a specific trigger by day 7, add a yes/no field for it — but never start with more than three. The full method for confirming a candidate is in [how to find your personal triggers](resource:how-to-find-your-personal-triggers).
Key takeaways
- Three fields beats ten — consistency is the whole game.
- A 1–5 number is the single most useful field over time.
- Add fields only after a candidate pattern shows up.
- Missed days log as 'skipped' — not as failure.
Frequently asked questions
Should I track at the same time every day?
Yes. Tying the entry to a fixed moment (after coffee, before bed) is the strongest predictor of whether you'll finish 14 days.
What if I have more than one symptom?
Pick one or two as your primary signal. You can note others in the free-form line, but rating more than two each day usually breaks the habit.
Is paper or an app better?
Whichever you'll do for 14 straight days. An app makes pattern review easier at the end; paper is sometimes easier to sustain.
Does Your Body Signal replace a doctor's notes?
No. It helps you observe patterns in your own data — it does not diagnose or replace medical care.
