Why does screaming hurt my voice?

When we speak or sing, our vocal folds vibrate against each other and the air from lungs passes through the vocal folds to produce sound. Speech is further formed with the help of articulators such as tongue, teeth, nose and sinuses. The rate at which the vocal folds vibrates is called the pitch which differs between men and women. In men it is approximately 120-140 hz and in women it is much higher of about 180-220 hz. The loudness generally depends upon the force with which the sound is produced.

When we scream, the collision of vocal folds causes injury to the lining epithelium along with tear in the blood vessels lined in the vocal fold causing bleeding within the vocal fold along with swelling. This change in the texture of the vocal fold causes excess strain in producing sound and further pain while talking.

The damaged tissue over time can cause permanent changes in the voice. When you encounter such a situation it is best for you to take good voice rest. Take adequate amount of water to keep your voice box hydrated. Avoid excessive throat clearing or coughing.

If you experience hoarseness for more than 1-2 weeks, then it is probably best for you to schedule your appointment with the nearest laryngologist and voice doctor.
