Track the transition in both directions
If you only noticed once you were halfway to the station, write “noticed about five minutes into the walk”. If you don’t remember the exact time it settled, write “clear by the time I reached my desk”. The record still shows the order.
| Moment | What to write |
|---|---|
| Before leaving | Whether your nose was already running or blocked and where you were |
| Going outside | When the runny nose first appeared and what you were doing |
| Going back inside | What you noticed on return and when it eased, if you remember |
| Similar trip | A comparable trip when symptoms were different or absent |

Compare two trips you already made
Tuesday fits the pattern that made the writer curious. Friday gives a counterexample. On Sunday the symptom was there before they stepped outside. You can keep all three without assigning a cause to each one.
A change in humidity or another exposure can happen around the same time. The NHS also lists smoke, perfume and exercise among possible non-allergic rhinitis triggers. If something obvious changed, record it. There is no need to create a test or deliberately repeat a situation that made you uncomfortable. NHS non-allergic rhinitis
| Fictional trip | Going out | Coming back in |
|---|---|---|
| Tuesday to the shops | Nose felt clear indoors. Started running within a few minutes outside. | Still running when I got in. Clear by the end of breakfast. |
| Friday on the same route | Cool morning, slower walk. Nose felt clear throughout. | No change noticed indoors. |
| Sunday after a visit | Nose was already running in the hallway. | Not checked after getting home. |

If it happens after coming back indoors
Write the first place you noticed the change. “Clear outside, started running once I got into the station” captures an indoor onset. Record any obvious difference such as a warm platform or strong smell. If it continued while you were at home later, add that as a separate observation rather than extending the first time estimate.
Bring examples if it keeps happening
If a runny or blocked nose keeps returning, affects daily life or you’re unsure what is behind it, speak to a pharmacist or GP. Mention if symptoms also happen when the temperature stays about the same. For a room-specific pattern, use the indoor conditions diary. If the main symptom is facial pressure on days the weather changes, see the weather and facial pressure guide. NHS non-allergic rhinitis
AirBloom is being built to show symptom entries alongside available local weather. A quick note about the moment you stepped outside or got back indoors adds the part a weather reading can’t capture.
