You probably learned when you were young that your voice comes from your voice box, also called your larynx. The larynx contains muscles called “vocal folds” that are covered by a mucous membrane. For your vocal folds to vibrate properly and produce a clear voice, you must keep the mucous membrane hydrated. Systemic hydration means maintaining healthy hydration levels throughout the tissues of the body.  Long-term hydration is far more important than short-term hydration, so chugging water the day before a performance will not help you Drink, at minimum, 8 glasses of pure water — not tea, not soft drinks — every day. Avoid dehydrating drink that contain alcohol and caffeine. Drink extra water to compensate for alcohol or caffeine if you drink them. Avoid all carbonated drinks, even uncaffeinated ones, if they give you reflux. Besides keeping your tissues internally hydrated, you can also keep your vocal cords moist and healthy through external means.  Sip your 8 glasses of water throughout the day instead large amounts at once. This will ensure consistent external hydration. Chew gum and suck on hard candies to keep our salivary glands engaged. Swallow saliva from time to time to clean out your throat without clearing it, which is bad for your vocal cords. Maintain a humid environment. If you live in a dry climate, you can purchase a personal steam inhaler at a pharmacy or hold a hot wet towel over your mouth and nose for a few minutes. You may love singing, but if you want to do it well, you need to take breaks from time to time. Just as athletes rest muscle groups for a day before working them out again, you need to rest the muscles that produce your voice to avoid injuring them through overwork.  If you practice or perform three days in a row, take one day off. If you practice or perform five days in a row, take two days off. Avoid speaking unnecessarily on a day-to-day basis if you have a rigorous singing schedule. Inhaling any kind of smoke, whether first or second-hand, dries out the vocal folds. Smoking can also decrease saliva production, which is important for topical hydration, and increase acid reflux, which can irritate throat tissues. The most important effects, though, are decreased lung capacity and function and increased coughing. Your instrument is your body, so you have to take care of it. Obesity is correlated with poor breath control, which is one of the most important skills a singer must master, so keep your weight down through a healthy diet and lifestyle.  Avoid dairy products that create excess mucous that causes you to clear your throat. Avoid excessive caffeine or alcohol, both of which dehydrate the body Eat enough protein to handle the workout your vocal muscles are wearing out through regular use.  Exercise regularly, both to keep your weight down and to improve your lung capacity and breath control.
