• Lungs
• Glottis
• Oral cavity and nasal passages.

All of these parts are surrounded by muscles that contract and expand, as well as ligaments and cartilage that adapt to the flow of air and, consequently, to the voice.

And it is in the larynx—which is situated between cartilages—that the vocal cords are located and where the voice originates.

But sometimes, due to stress, muscle tension affects these muscles, leading to loss of voice and even blocking the pharynx—a condition known as a hysterical globus.

And it is breathing that plays a very important role in the changes to these structures and, of course, in the change of voice.

If we disrupt our breathing rhythm, we not only experience an anxiety attack, but we also tense our lips, pharynx, larynx, and vocal cords excessively… creating more tension, pain, and a reduction in sound production.

In addition, it increases dry mouth, palpitations, and thus physiological stress.

Practicing deep breathing not only alleviates and reduces stress, but also restores muscle flexibility in the areas involved in voice production.

It also restores energy and flexibility to these muscles.
