Drinking too much coffee will make your voice worse.

Many people like to drink coffee and tea, but if they drink too much coffee and tea, it may affect the sound quality.

Coffee and tea all contain caffeine. If you consume too much caffeine, it will easily cause vocal cord dehydration, and the vocal cords will also be stimulated, so the sound quality will naturally become worse. In addition, eating too much caffeine can also lead to acid reflux, which can easily affect the vocal cords.

In addition, the factors affecting sound quality include long-term use of vocal cords, long-time roar, nasal reflux, gastroesophageal reflux, often eating spicy food and so on. However, if the voice suddenly becomes hoarse and lasts for 10 days to two weeks, or if there are symptoms such as pain near the throat, dyspnea, dysphagia, etc., it is suspected that it may be caused by a tumor. It is best to see a doctor as soon as possible and undergo detailed examination.

Not only the whole body needs to have a health check-up, but also the vocal cords need a health check-up, so that abnormalities can be detected early and treatment can be carried out as soon as possible. The functional examination of the vocal cords is different from that of the general otorhinolaryngology. When speaking, the vocal cords vibrate 200 to 300 times per second. Generally, the otorhinolaryngology examination can only see the static structure of the vocal cords, but not the subtle vibration of the vocal cords. If you want to observe the vibration of the vocal cords, you have to use "laryngeal flash endoscopy", which uses flash frequency to record the movement of the vocal cords, which is somewhat similar to the principle of visual temporary animation. In this way, subtle structural changes of the vocal cords can be further observed.
