If it is adolescence, don't eat too spicy food. Excessive spicy eating habits, smoking, drinking, excessive use of sound, etc. Will lead to abnormal vocal cord development in adolescence, leading to fatigue, fragility, poor sound quality, air leakage and even vocal nodules in future life. You know, these problems will accompany you all your life!
If it is after puberty, we should know that after the age of 28, the functions of human vocal cords and other aspects of the body are slowly declining, so we should protect ourselves with a healthy lifestyle. Fry less, avoid spicy food, and don't do strenuous exercise in places with poor air environment. In addition, the ear canal and the throat are connected, which effectively protects yourself from ear canal diseases such as otitis media and is also good for the throat.
If you like spicy and fried food very much, I advise you to eat as little as possible, which is very harmful to the vocal cords and the bottom of the throat. Many people think that screaming will wear the vocal cords, and only half of this view is correct. First of all, if your vocal cords are unhealthy, there are nodules, air leakage, pharyngitis and other problems, you can't scream. If you can scream, it proves that your vocal cords are sub-healthy at least so far and should be well protected. In addition: to some extent, screaming will not damage the vocal cords, but you often practice or improve the singing range, so this problem should be viewed from two aspects.
I hope these can help you, welcome to ask questions! Pure hand tour, hope to adopt!
