What it is
Upper and lower airways, connected
Sinus and respiratory symptoms can involve allergy, asthma, infection, reflux, structural problems, or irritation. More than one factor can be present.

Sinus &
respiratory.
Congestion, cough, wheeze, and irritation deserve attention to both the airways and the air around you. Explore the patterns to notice, the assessments to discuss, and practical ways to find support.

Why it’s missed
Treatment and source assessment can work together
Symptoms may fluctuate with season, room, sleep, activity, or infection. Their timing can help direct questions, but no one pattern proves an indoor source.
Commonly reported symptoms
What people notice.
These symptoms and concerns can overlap with other conditions. A pattern supports a conversation with a clinician; it does not establish a diagnosis.

The body & environment
Follow the breath.
Notice the setting.
Six connections to bring into the conversation. Use these clues to guide the questions you ask.
01
Dampness & mold
Report leaks, visible growth, and musty odors. Moisture inspection and source correction matter; a dust score is not a diagnosis of illness.
02
Plumbing gases
Hydrogen sulfide can irritate the airways. A suspected gas problem needs professional assessment, not a smell-based safety check.
03
VOCs & fragrances
Some compounds and aerosols can irritate the airways. Record product use and repeated symptom changes without intentionally testing a trigger.
04
Smoke & combustion
Smoke particles and nitrogen dioxide can worsen airway symptoms. Carbon monoxide has a different, potentially life-threatening mechanism and may provide no irritation warning.
05
HVAC & airflow
Ask about filters, damp components, ventilation, and actual inspection findings. Symptoms during operation do not automatically mean contaminated ductwork.
06
Humidity & allergens
Moisture control can help limit mold and dust mites. Monitor conditions and address the source of excessive humidity rather than relying only on air cleaning.
What to observe & assess
Small observations.
A fuller picture.
Clinical care and source assessment work together. Bring symptom patterns, treatment use, lung-function findings, and credible exposure observations into the conversation.
01
Daily symptom timing
Record when breathing and congestion change.
02
Location & outdoor conditions
Compare settings with context.
03
Treatment & action-plan record
Document what helps and what does not.
04
Airway testing
Assess lung function when appropriate.
05
Building & exposure review
Connect observations with qualified inspection.
What to do next
Start small.
Take the next step.
Choose what feels manageable. Use these steps to organize observations, care, and practical support. Address urgent symptoms first.
- Severe breathing difficulty, blue/gray lips, or inability to speak normally needs emergency help.
- Follow your prescribed rescue plan; do not stay to investigate an exposure.
- Describe symptom duration, nighttime waking, and activity limits.
- Bring medication use and any prior lung-function or allergy results.
- Ask about inhaler technique and when to seek further help.
- Do not stop controller treatment because you are investigating the building.
- Use appropriate building professionals for persistent concerns.
- Correct verified leaks or hazards without disturbing suspected contamination yourself.
- Limit smoke and products that repeatedly cause problems.
- Filtration can supplement source control; it does not remove every gas or hazard.
- Track a few symptoms and treatment needs after interventions.
- Discuss persistent sinus or lung symptoms with the relevant clinician.

A grounded first step
Care for the airways.
Look at the air, too.
Bring clinical findings and credible exposure observations together. Both can help shape a practical plan.
