Most serious talkers and singers have already heard that it’s important to drink a lot of water. This water does not directly “wet” the vocal folds. Swallowing water sends it down the other tube, the esophagus, into your stomach. Drinking plenty of water does make sure that the cells inside the voice box are nourished and resilient. If the body as a whole is dehydrated, the vocal folds get tired faster, and they recover more slowly from heavy use.
Recommendations on the right amount of water intake range from two quarts or two liters per day to “whatever it takes to pee pale.” A general rule of thumb is to divide your weight in pounds by 2 and drink that number of ounces (see Figure 1). Sipping your water throughout the day and evening is much more beneficial than trying to drink a lot all at once.
