According to some data, foreign scientists compare 20 old singers with their peers who don't sing often, and find that singers have developed chest muscles, good cardiopulmonary function and slow heart rate, so they come to the conclusion that singing is an "aerobic fitness method".

Experts from Frankfurt University have also studied professional singers and found that singing can really increase the concentration of protein, that is, immunoglobulin A, in the human immune system, thus improving human immunity. It has also been counted that singing a song in the right way consumes nearly 20 calories, which is equivalent to running 100 meters.

In the opinion of professional doctors, the effect of singing and aerobic exercise is because singing uses abdominal breathing. Abdominal breathing is a simple and efficient breathing exercise method, which is very helpful for the treatment of respiratory diseases.

JUNG WOO, a vocal music teacher of the Art Troupe, said that the general way of breathing is chest breathing, because the micropores in the diaphragm are blocked, which affects the circulation of qi, and usually inhalation can only reach the lungs; When you sing, you must have enough breath to make the sound continue to sound and form a singing method. The chest will be extremely inflated and the diaphragm will have a chance to drop. So the effect of singing is just like exercise.
