They’re a Good Kind of Cavity

Sinuses are pockets in the skull and facial bones. Thanks to their hollow nature, we’ve got a little less weight on our shoulders. NICE!

They Keep Things Damp

Sinuses are lined with a layer of mucus that helps moisten the air we breathe in so our noses don’t dry up like a desert floor.

They Bring on the Pressure

When allergies cause mucus membranes to swell, they block your sinuses. This makes it hard for sinuses to drain and it makes your head feel full of pressure.

When they’re healthy and clear, sinuses are empty spaces, giving your voice more resonance. When filled with mucus, they make your voice more muddled.

Sinuses help trap the bad stuff we breathe in, like dust and germs. Then, that bad stuff drains into the nasal passage, and BAM! You’ve got snot.
