Question 1

Why are my allergies worse today?

Accepted Answer

High humidity, elevated PM2.5, and rapid barometric pressure changes are the three biggest triggers. The Achoo Score combines all three into a single daily number.

Question 2

What time of day are allergies worst?

Accepted Answer

Peak heat and humidity in the afternoon are usually the worst window. Go out when the Achoo Score is low and the Air Feel is Crisp.

Question 3

How does humidity affect sinuses?

Accepted Answer

High humidity — measured by dew point — causes nasal tissue to swell and slows mucus clearance, leading to congestion and pressure buildup.

Question 4

What does the Achoo Score mean?

Accepted Answer

0–30 means conditions are good and no pill is needed. 30–60 means be aware if you are sensitive. 60+ means protect yourself — take medication before symptoms start.

Question 5

How do I reduce sinus symptoms today?

Accepted Answer

Hydrate early, avoid going out during peak heat and humidity, and take medication before symptoms hit rather than reacting to them.
