Kids will be heading back to school in a few weeks and that’s exactly when asthma and allergies can flare up.

As parents prepare for the new school year, you may want to schedule an appointment with your child’s allergist. Because right after Labor Day, the “September Spike” begins.

It’s a term hospitals use to describe the influx of children experiencing allergy and asthma flare-ups. This happens because during the summer, a lot of kids go off their medications. And once they return to school, they get exposed to more allergens in all kinds of places, like the classroom, the cafeteria, the playground and in the school field.

The more common triggers found at schools are dust mites, chalk dust and mold. On top of that, ragweed season kicks off in late summer. And this pollen can cause hay fever leaving sufferers with irritated eyes, runny nose, nasal congestion and sneezing.
