* Drink plenty of water. Staying hydrated helps to keep your vocal cords healthy and lubricated, which can prevent hoarseness and other vocal problems.
* Avoid caffeine and alcohol before singing. Caffeine and alcohol can both dehydrate you, which can have a negative impact on your voice.
* Get enough sleep. When you're tired, your vocal cords are more likely to be strained or injured.
* Practice good vocal hygiene. This means avoiding things that can damage your vocal cords, such as yelling, smoking, and clearing your throat too often.
* See a doctor if you have any vocal problems. If you experience persistent hoarseness, pain, or other vocal problems, it's important to see a doctor to rule out any underlying medical conditions.
