How to breathe healthily? What are the benefits of abdominal breathing?

There are two main ways of breathing: chest breathing and abdominal breathing. The way of breathing, which is mainly based on the expansion and contraction of the chest, belongs to chest breathing and is mainly used by women in general. If the way of breathing is mainly based on the contraction and relaxation of abdominal muscles, it belongs to abdominal breathing, which is generally adopted by men. When people are exercising or have a fever, the respiratory movement increases, usually accompanied by mixed breathing. In addition, some patients with lung diseases need to do prone breathing, which is helpful to improve hypoxia.
