透过鼻子来进行呼吸有多重要呢？练习一下看英文：
The Buteyko Method teaches you how to bring your breathing volume back toward normal or, in other words, to reverse what’s called chronic hyperventilation（慢性换气过度） or chronic overbreathing（慢性过度换气）.
One of the most important aspects of proper breathing is breathing through your nose. Part of the benefits of nose breathing is related to the fact that there is nitric oxide（一氧化氮） in your nose, and when you breathe through your nose, you carry a small amount of this beneficial gas into your lungs.
Nitric oxide not only helps maintain homeostasis（体内平衡）, or balance, within your body, it’s also a bronchodilator（支气管扩张剂）and vasodilator（血管舒张）, and has antibacterial（抗菌） properties that helps neutralize germs（微生物) and bacteria（细菌）.
Nose breathing also helps normalize your breath volume. This is important because when you chronically overbreathe, the heavier breathing volume that’s coming into your lungs can cause a disturbance of blood gasses, including the loss of carbon dioxide (CO2).
