T MAY BE kind of gross to think
about, but your nose is continually
making mucus—and that’s a good
thing. This sticky secretion traps and
neutralizes dust, pollution and germs,
which helps protect you against infec-
tions and airway irritation. It also
humidifies the air you breathe and
moisturizes your nose, preventing its
lining from drying out and cracking.
Under normal, healthy circum-
stances, nasal mucus simply gets swal-
lowed without causing discomfort. But
when it’s especially thick or copious,
you can become conscious of it drain-
ing from your nose into your throat.
You can also experience coughing,
soreness, tickling, a raspy voice or a
frequent need to clear your throat.
Known as postnasal drip, this annoy-
ing symptom can be caused by a wide
variety of conditions. Common trig-
gers include hay fever, colds and flus,
all of which prompt the body to prod-
uce more mucus or make changes to
the usual texture in an effort to rid
itself of pathogens (or what it mistakes
for pathogens, in the case of allergies).
