People should be guarded by old age
When people reach old age, the functions of various organs of the body will be degraded. The best organ is the same as the throat. If you don’t pay attention to protect the scorpion, if it is too much, it will be hoarse and dull.
銆€銆€The larynx is the most important organ of importance.
At the time of attention, the vocal cords are displaced to the midline, the glottis is closed, the airflow exhales the impact vocal cords from the lungs, and the sound is emitted. Then, through the resonance of the larynx, pharynx, nasal cavity and chest cavity, and the coordination of the lips and teeth, it is issued.Different sounds.
The length, thickness, tension and elasticity of the vocal cords play a decisive role in the best.
The laryngeal mucosa of the elderly is atrophy, the nervous system control ability of the larynx is reduced, and the vocal cords are aging. The reduction of the vocal cords and the number of fibers reduces the elasticity of the vocal cord muscles and the exercise capacity is poor. Therefore, the volume becomes small, the appropriateness is weak, the sound quality is degraded, and the lack of sound is suppressed.
銆€銆€Hoarseness is a common symptom of vocal diseases. In general, it is caused by acute annihilation of the larynx, laryngeal tuberculosis, vocal cord masses such as polyps, nodules, benign and malignant tumors of the throat, and mental and neurological factors.
It is worth noting that hoarseness sometimes becomes an early sign of tumors in the lungs, esophagus and mediastinum.
Because the tumors in these parts oppress the recurrent laryngeal nerve, and the recurrent laryngeal nerve is the motor nerve, the oppressed will cause hoarseness. Therefore, those who are over 50 years old and continue to have hoarseness for more than one month should be vigilant and timely check.
銆€銆€To delay the aging of the voice, we must first prevent respiratory diseases.
To avoid talking loudly at both ends, you should drink plenty of water, eat less spicy and irritating food, eat lighter, cool food and eat vitamin C, E food, pay attention to indoor environment and hygiene, and prevent indoor dryness.
