Practice reciting how to protect your voice.

1 First of all, we should pay attention to outdoor activities.

Enhance the body's defense ability against diseases and avoid pharyngitis and laryngitis. The second is to develop the habit of throat hygiene. Rinse your mouth with clear water before and after meals, drink more tea at ordinary times and keep your throat clean. Smoking and drinking should be moderate, otherwise it will stimulate the throat and produce chronic inflammation.

2. Avoid excessive use of sound.

Don't scream, don't talk loudly in noisy places. If you feel dry or hoarse, stop talking. Keep your voice normal, neither too high nor too low, and whispering is not good for protecting your voice.

3. Don't clear your throat too much.

Because when doing so, the air will violently vibrate the vocal cords, thus damaging the vocal cords. If you feel a sore throat, you can drink saliva or swallow it. But if you have to clear your throat all the time, go and see a doctor. It may be reflux disease, allergies and other diseases.

4. Drink plenty of water and avoid drinking alcohol and coffee. Keeping the water balance in the body can fully moisturize the vocal cords.

Don't smoke, even passive smoking should be avoided. Smoking can significantly increase the risk of laryngeal cancer.
