The full answer
Yes, in specific situations — most often active baking with flour
Airborne wheat flour, especially during active baking or bread-making where flour is being tossed, sifted, or kneaded, can be inhaled or settle on nearby surfaces and food, creating a real (if less obvious) exposure risk for sensitive individuals.
When this is worth being cautious about
This is generally more relevant in active baking environments than everyday household situations — if you’re highly sensitive, it’s reasonable to step out of the kitchen during heavy flour use or ask others to bake in a separate space.
