The teacher said that running in the morning and shouting slogans are conducive to the discharge of waste gas in the body. Is it true?/You don't say.
I don't know what education your teacher has. The only waste gas produced by human body is carbon dioxide, which circulates with normal breathing. The circulation of gas when shouting slogans is only the normal work of the human respiratory system. There is no exhaust gas discharged from the body. Of course, toxins in the human body will not be excreted with the respiratory system.
