Allergy Trigger Diary

Each time symptoms flare, or at the end of each day, tick the possible triggers and symptoms and rate severity. Over time the diary ranks triggers by how much worse your symptoms are when they are present.

Track treatment

See if antihistamines or changes at home reduce severity.

Common allergy triggers

Seasonal triggers include tree, grass and weed pollen, which peak at different times of year. Year-round triggers include dust mites, pet dander, mould and cockroaches. Food triggers can cause hives, swelling or digestive symptoms.

Severity is subjective, so try to rate it the same way each time: 0 for none, 3 for mild, 6 for moderate that affects your day, and 9-10 for severe. Seek urgent care for breathing difficulty or facial swelling.

Seasonal

Tree, grass and weed pollen, outdoor mould spores.

Indoor

Dust mites, pet dander, indoor mould.

Other

Foods, fragrances, smoke and medicines.

Allergy diary FAQ

How does the trigger ranking work?

For each trigger it averages severity on entries where the trigger was ticked and on entries where it was not. A big positive difference suggests the trigger is linked with worse symptoms.

Does a high ranking prove an allergy?

No. It shows a pattern in your notes, not a cause. Triggers often occur together, such as pollen and outdoor exercise. Share the diary with an allergist who can test properly.

Should I log days without symptoms?

Yes. Logging calm days with severity 0 gives the comparison much more power.

How many entries do I need?

Patterns become meaningful after two to three weeks of daily entries. Triggers with fewer than three entries are marked as low data.

Is my diary private?

Yes. Entries are stored only in this browser. Export a CSV to back up or share.
