Question
Why do children change their voice at 3 years old? Have you treated any cases within the last year? What kind of assistance is needed? What impact does this change have on the child, and how should it be treated?
Answer
Excessive vocal use or frequent crying in children may lead to damage to the vocal cords, causing changes in voice. When producing sound, as the frequency increases, the tension on the vocal cords also increases, leading to over-tension of the vocal cord muscles, pushing against each other and striking. Recommended treatments include clearing heat and cooling blood, promoting blood circulation, and resolving clots. This can be achieved by giving children Chinese medicine like Qingyin Wan or Houzheng Wan orally, or by brewing and drinking water with maxims and ophiopogon. At the same time, it is advisable to avoid long periods of loud speaking or crying, consume more vitamin C-rich foods, fresh vegetables, and fruits, and avoid spicy and irritating foods.
