Allergen Trigger Sensitivity Correlation
Based on your saved symptom records and local allergen levels, your strongest correlation is with Tree Pollen (Birch/Oak). Days with high tree counts correlate with peak ocular (itchy eye) flare-ups.

Clinical Allergy Mitigation Protocol
Evidence-Based Guidelines
1. Home Ventilation & Filtration
Keep bedroom and home windows sealed tightly between 5:00 AM and 10:00 AM, when airborne pollen concentrations peak.
Operate a True HEPA air purifier in the bedroom continuously on medium or high setting.
Avoid drying laundry or bed linens outside on clotheslines, which trap millions of microscopic spores.
2. Personal Decontamination Routine
Shower and wash hair immediately upon returning from extended outdoor activities to prevent transferring pollen to pillows.
Change outdoor clothing upon entering the home and store jackets away from sleeping areas.
Wear wraparound sunglasses outdoors to physically shield the ocular conjunctiva from drifting airborne particles.
3. Medical Timing & Nasal Rinses
Perform isotonic saline nasal irrigation (using distilled or boiled water) in the evening to mechanically flush allergens from the nasal mucosa.
Take non-sedating oral second-generation antihistamines (e.g. Cetirizine, Fexofenadine, Loratadine) 1 to 2 hours before peak exposure.
Intranasal corticosteroid sprays require 5 to 7 days of continuous daily usage to establish full anti-inflammatory protection.
About this tool
How to use it
Select your city or region from the popular location presets, or search by city name.
Inspect the current pollen severity index across Tree, Grass, Weed, and Mold spore categories.
View the 5-day allergen forecast and tailored medical action advisory (HEPA filtering, window ventilation timing, and outdoor exposure windows).
Use the Daily Symptom Tracker to record sneezing, eye irritation, and congestion to correlate your symptoms with specific allergen peaks.
Why it matters
Seasonal allergic rhinitis affects over 400 million people globally. Accurate pollen forecasting combined with personal symptom journaling allows allergy sufferers to proactively take antihistamines before mast cell activation rather than treating symptoms reactively.
When to use it
Consult this tracker daily during spring, summer, and autumn pollen surges, or when planning outdoor exercise, gardening, or doctor allergy consultations.
Common questions
How is the Pollen Severity Index calculated?
The index standardizes aeroallergen concentrations on a 0 to 12 scale based on grains per cubic meter (grains/m3). Scores 0-2.4 are Low, 2.5-4.8 are Moderate, 4.9-7.2 are High, and 7.3-12.0 are Very High.
What times of day have the highest pollen counts?
Tree and grass pollen generally peak between 5:00 AM and 10:00 AM and again in late afternoon as cooling air lowers suspended spores to ground level. Windy, dry, and warm days produce the highest counts, whereas rain washes pollen out of the atmosphere.
