DON’T overuse your voice. Most damage to the speaking and singing voice is caused by overuse. NEVER push your voice to the point of hoarseness.
DON’T dry out your mucous membranes. Dry membranes are more susceptible to injury as well as infections.
DO drink at least 8 glasses of water per day to stay hydrated.
DO get plenty of rest to keep your voice and body healthy.
DON’T sing if you are sick. If a cold or flu is having any negative effect on your voice, don’t sing! Singing with inflamed or irritated vocal cords can delay recovery and even cause serious vocal injury.
DON’T speak or sing in the wrong tessitura (range). Know which pitches are comfortable for your voice, and don’t push the extremes of your range.
DON’T speak too loudly. Screaming, laughing too loudly, or talking over loud noises are hard on the voice. Whispering is also problematic, as it can cause tightening in the throat.
DON’T take certain drugs before singing.
Aspirin – makes capillaries more fragile and can increase the chances of hemorrhaging in the vocal folds. Ibuprofen (Advil) can have the same effect, but acetaminophen (Tylenol) is safe for singers.
Antihistamines and Decongestants – dry out the mucous membranes. If antihistamines are absolutely necessary, counteract the drying effect by drinking lots of liquids and inhaling steam.
Hormones – including some oral contraceptives, can have side effects including the thickening of the vocal folds. This can result in a deepening of the voice, hoarseness, or difficulty singing higher pitches.
DO find a good laryngologist or ENT who specializes in working with singers. It’s a good idea to schedule an appointment while you are healthy to establish a baseline. This makes it easier to detect and diagnose changes and problems when they occur.
DO see a doctor if you experience any prolonged vocal difficulty or unexplained changes in your voice. Continuing hoarseness, loss of range, difficulty producing sound, and persistent breathiness are some of the warning signs that should be investigated by a doctor.
DO be honest with your voice teacher and doctor about how you are using your voice, and follow their recommendations carefully.
DO pay attention to your voice and how it feels. Some singers can’t have dairy or chocolate before singing because it increases phlegm production. Some singers feel better after drinking certain herbal teas. Pay attention to what works and doesn’t work for you.
