WHY DOES MY THROAT GET
DRY AND MY VOICE GET HOARSE?
We all have occasions
when we develop a dry, sore scratchy throat and a hoarse, tired
voice - we call it laryngitis. This is not always a correct
diagnostic term, but it is descriptive - possibly because
tissues in the larynx or vocal apparatus are inflammed- sound is
distorted. Often it's caused by excessive vocalizing: too
much speaking, singing, cheering at games or concerts, shouting,
etc. 
Inhaled air almost always is drier than
the body would prefer because heating in cold weather as well as
conditioning in hot weather removes moisture. When this dry
air flows through the throat's passageways, its mucosal cover loses
moisture via evaporation. As a consequence, this coating or
lining becomes too viscous to flow properly and it cannot keep the
underlying sensitive membranes moist. These surfaces can
become dehydrated even if one is not doing an unusual amount of
talking or singing or yelling.
Other reasons: maybe the dry irritated
throat is due to an unfavorable atmosphere like smoke or dust, or
maybe it's an after-effect from a cold or cough or the result of
surgery or therapy. Allergies can cause the mucus to form
a thick and congested mass. Whatever the cause, the throat
feels uncomfortable and, because a dry vocal fold does not vibrate
like a moist one, vocal quality is impaired.
WHY DO ANYTHING ABOUT IT?
A
dry throat is uncomfortable and a persistently dry throat is more
susceptible to inflammation and infection - problems which nobody
needs. A hoarse voice handicaps our ability to perform our
job or participate in a favorite activity. It is annoying
to the person doing the vocalizing and equally irritating and distracting
to the listener.
A few of us, radio announcers and opera
singers, for example, have jobs that absolutely demand one's very
best voice all the time. However, a far greater number of
us are involved in everyday activities that require a degree of
vocal quality, e.g. conversing, explaining, teaching, presenting,
or selling - if we want to optimize our opportunity to communicate.
A scratchy hoarse voice is frustrating to both parties. The audience,
whether it is one person or an auditorium full, is short-changed,
receiving less than the speaker or singer is capable of delivering.
WHY NOT JUST DRINK WATER?
Drinking
lots of water is good, a healthy and a smart idea for many reasons.
Before extended periods of vocalizing one should drink a lot of
water. But the water passes through the esophagus into the
digestive system and must get into the circulatory system before
it can be delivered to specific dehydrated areas such as the throat
or larynx. Very little ingested water comes into direct contact
with these dehydrated surfaces. Frequent, often inconvenient
bathroom breaks become necessary. Moreover,
even with copious fluid intake to achieve systemic hydration,
the body's mucous-secreting glands often just can't produce
enough replacement moisturizing materials quickly enough to keep
up with the increased need.
WHAT ABOUT OTHER BEVERAGES?
Some
people find fruit juices and other water-based fluids a better tasting
alternative, but many drinks are counter- productive. For
example, alcohol and caffeine both exert a drying effect; paradoxically,
the more one drinks the dryer the local membranes and total system
becomes. Even sugar or acid (e.g. carbonation or citric acid)
in drinks reduces the effectiveness of these beverages as
humidifiers and makes them less efficient than plain water.
