When we are about to start on important occasions such as speech and singing, many people may perform the action of "clearing their throat" many times, in order to make the voice more crisp and avoid sputum and other situations.
However, some people also frequently clear their throats in their daily lives, which may actually cause damage to the vocal cords, because clearing the throat is an obvious hard breath sound.
The so-called hard air sound, is to increase the air pressure under the glottis, violently from the bottom of the vocal cords to open the vocal cords, as if pushing open a hidden door, in this case, the impact on the vocal cords is relatively large, it is possible to cause damage to the vocal cords.
In fact, in daily life, many people's pronunciation methods are also not good for the vocal cords, such as when speaking, the habit of speaking with a hard tone, the tone is very intense, the pronunciation in this case, but also a strong impact on the vocal cords, for a long time, will cause damage to the vocal cords, resulting in hoarseness and so on.
In addition to frequent throat clearing and long-term use of hard breath sounds, long-term cough also has an adverse effect on vocal cords, and the principle is similar to clearing the throat. When we want to clear our throats, we can use the method of drinking water to moisten the throat instead of better protecting the vocal cords.
