Be the Person Your Vocal Cords Deserve

The voice is a strong instrument, but if you’re reckless, singing can endanger your body.
Vocal cords are part of the larynx, a tube-shaped organ in your neck that acts as the body’s voice box in addition to blocking food and drink from entering your lungs through the trachea. When the cords vibrate, they control the amount of air your lungs release while you speak—they also produce the sound, or pitch, of your voice.
When you’re singing, vocal cords vibrate for longer increments of time while your lungs exert more pressure. You’re going harder, which means there’s a higher risk of damage.
What Goes Wrong
The most common (and preventable) cause of vocal cord damage is overworking your throat. Singing without warming up can make you feel raw or scratchy sooner, and persisting too far hurts your body and your pitch. Certain styles of singing—belting, screaming, anything harsh or unnatural—are more likely to strain your vocal folds. Straining to hit a note that’s out of your range—too low is just as bad as too high—can also cause damage. Other self-destructive behaviors such as smoking or excessive drinking (alcohol dries out the throat) can jeopardize your voice in addition to other parts of the body.
Alternately, a strained voice can be a symptom of another malady such as an upper respiratory (that includes the bronchial tubes, larynx, nose, throat and pharynx) infection, acid reflux, larynx cancer or even psychological trauma.
The bottom line is that if something feels or sounds wrong, then it’s probably hurt.
Effects of Strained Vocal Cords
As with the rest of the body, ignoring strained vocal cords can lead to farther damage. You’ll also sound much worse. Damaged vocal cords often restrict one’s singing range, lower the speaking voice or even cause squeaking during singing.
Because of their proximity to the ears, nose and throat, damaged or strained vocal cords can affect the surrounding organs. If only one side of your throat hurts, it’s because you’ve hurt the corresponding lymph node. Voice box pain can easily spread and infect the throat and middle ears. Of course, overexertion can also paralyze vocal cords.
