Mouth Breathing or Nasal Breathing-Why does it matter?

As we all know, breathing provides our bodies with oxygen which is critical for survival. Most people don’t give much thought to how that oxygen enters their body. Are you breathing through your nose or your mouth or a combination of both?

Well, studies suggest that close to 80% of the population breathe wrong and that can have a detrimental effect to your overall health.

Breathing with our nose is how the body was designed. And when we use the body the way it is designed it functions better.

Nasal breathing filters the air as it passes into the body and creates the optimal oxygen-carbon dioxide exchange resulting in a balanced PH. Another benefit to nasal breathing is the production of nitric oxide.

Our sinuses produce nitric oxide which is known to fight harmful bacteria and viruses (like COVID-19), it regulates blood pressure and improves the body’s immune system.
