1 Allow children who are 6 and older to hold poses and do exercises for up to 1-1/2 minutes, or 90 seconds. 2  Older kids can often endure yoga sessions up to 25 minutes.. Teach kids how to breathe. Relaxed and deep breathing is essential to the practice of yoga. 1  Explain that proper breathing produces calm, allows focus and increases energy. 2  Kids often need to understand why they are asked to do something.
Respiration is the sequence of events that results in the exchange of oxygen and carbon dioxide between the atmosphere and the body's cells. Every three to five seconds, nerve impulses stimulate the breathing process, or ventilation, which moves air through a series of passages into and out of the lungs.
Cells use the oxygen and produce another gas, called carbon dioxide, as a waste product. It is very dangerous if carbon dioxide builds up in your body, so your blood carries the carbon dioxide to your lungs where it is released into the air when you breathe out or exhale.his module will help you understand how gas exchange occurs in the body and why it is so important. After completing this lesson, each student should be able to: 1  Diagram and label the anatomy of the lungs and the circulatory system. 2  Explain how the processes of gas exchange occurs and what purpose it serves.
