Jiang Honghua, Professor of Oriental Medicine Disclose to the world how humans can extend their lifespan First, remove all toxins from the muscle cells in our bodies and blood from the small pores. Second, we usually breathe through the lungs. Sometimes there is not enough oxygen in the body, and we need to add diaphragmatic breathing (that is, abdominal breathing) to transport all the air to the internal organs and to the whole body. When practicing, first gently press your hands on your belly button, then contract your belly and then start to inhale slowly until your belly is full and bulges out. You need to inhale to a certain depth so that the breath can enter the internal organs and the whole body.
