● According to the Spanish newspaper El Mundo, humans breathe between 20,000 and 25,000 times a day, but experts say many people use less than one-third of their breathing capacity. Experts point out that better breathing means breathing slowly, gently, and correctly, and not over-tiring the body. Incorrect breathing methods, such as breathing through the mouth, over-ventilating, and not using the diaphragm, will have a negative impact on physical health. (Source: Reference News)
