Allergic reactions and asthma both run on the same inflammatory signalling — with important limits on what lifestyle tracking can tell you.
This page is general education, not a diagnosis. If you're dealing with persistent or severe symptoms, please see a doctor — lifestyle tracking can be a useful complement to medical care, never a substitute for it. Asthma in particular can be a serious, sometimes life-threatening condition — always follow your prescribed action plan.
Allergic reactions and asthma both involve the immune system's inflammatory machinery — histamine release, cytokine signalling — triggered by a substance (pollen, dust, an allergen) that isn't actually dangerous, rather than by injury or infection.
Research has explored links between chronic low-grade systemic inflammation and the severity or frequency of allergic and asthmatic symptoms, though individual triggers (specific allergens, air quality, exercise, weather) usually matter more day to day than general dietary inflammation.
THE FAD does not track specific allergens and isn't a substitute for an asthma action plan, allergy testing, or prescribed medication. Its general lifestyle signals are a different, much broader category of information.
If you have asthma, always carry and use your prescribed medication as directed — this page is background reading, not symptom management guidance.
