MOUTH BREATHING
Healthy breathing occurs through the nose, with right amount of Oxygen intake while breathing in and release of Carbon-dioxide while breathing out. When you stop breathing from the nose, your mouth tends to open and you start breathing through your mouth instead. This leads to deficiencies in O2 (Oxygen), CO2 (Carbon-dioxide), and NO (Nitric Oxide) in body cells due to hyperventilation – a condition in which you start to breathe very fast.
Our nose acts as a natural filter for all the particulate material suspended in the air and warms it when the air passes through the nasal passage. In this manner, the air which goes inside our lungs is much cleaner than what we breathe directly through the mouth. When we breathe through our mouth, the air dries up the saliva which is a natural lubricant of the mouth as well as for all the food we eat. Due to this dryness, bacteria tends to grow faster in the oral cavity,
