1) Drinking Alcohol And Excessive Caffeine

This seems obvious, yet its one of the things i observe in the voice community the most. I’ve observed vocal teachers and musicians who believe their skills  protect them from harm, even while they smoke and drink frequently. Even while it might lessen some of the consequences,the struggle is still uphill. you’re not doing justice to your voice. Your body voice will appreciate you for breaking these negative behaviors

2)Using an improper vocal technique

Using improper technique can have lasting effects on your voice long term. It can cause you to constantly strain or consistently using shallow breaths and having tension when you sing. In the long term, that can damage your voice and make you lose clarity and limit your vocal range as well as cause your voice to be unreliable. It goes in and out. Sometimes you have a voice — sometimes you don’t. You never know what you’re going to get.

3. Chronic dehydration

There are people I’ve met who claim they dislike water. You are 50–75% water in your body, which astounds me. A well-hydrated body has many health benefits. You run a higher chance of suffering from problems including straining, raspiness, and voice loss when your vocal chords become dry.

5. Clearing your throat

Drink some water if you have a scratchy throat. To clear your throat, don’t cough! Every time you clear your throat, you injure your voice cords a little bit more, and your throat doesn’t get any better. In addition to taking expectorants during the day and cough suppressants at night, minimize the strain on your throat by taking throat lozenges and calming herbal teas along with your medication. Drink plenty of water to help break up the phlegm and keep your vocal cords hydrated.

5. Ignoring your body

Singing when unwell is NOT advised. Singing during your convalescence may result in polyps or cysts on your vocal cords, ruptures in the lining of your vocal cords, nodules that produce calluses on your cords, and fibrosis (thickening of the vocal fold lining). If left unchecked, all of this can result in irreversible harm, including persistent hoarseness, trouble with agility (the ability to switch between notes and registers without breaking), and in the worst situations, total loss of vocal range.

6. Not warming up

Never enter without warming up. You have to warm up your voice if you haven’t talked or sung all day. Without a warm-up, pushing your voice through difficult parts can cause damage and irregularities in your range and performance. Never neglect to warm up!

7) Untreated acid reflux

If left untreated, excessive stomach acid can seriously harm your throat’s lining and esophagus, which can ultimately harm your vocal chords. It’s time to treat your acid reflux if you start to burp a lot or get heartburn. Antacids, a lighter, more alkaline diet, and lots of water consumption can help with this.
