The Power of Nasal Breathing: Boost Your Health

I recently finished a book by Patrick McKweon titled “The Oxygen Advantage“. He makes a strong argument in favor of nasal breathing, explaining that in order for oxygen to be released from red blood cells it must exchange with carbon dioxide, a principle called the Bohr Effect.

In nasal breathing, the balance between oxygen and carbon dioxide is more optimal than mouth breathing.
It also supports balance in the sympathetic and parasympathetic nervous systems, often referred to as fight or flight (SNS) and rest and digestion (PNS). This is in part due to utilization of the diaphragm.
This combination, optimal oxygen levels and nervous system response, has various benefits. Listed are just a few:

Enhanced cardiovascular function and blood flow, leading to nutrient delivery and toxin removal from cells. Part of this has to do with nitric oxide being produced in the sinuses.

Respiratory health, with stronger lungs and more responsive airways, and may also reduce asthma symptoms.

More efficient mitochondria and metabolism, in part due to better oxygen utilization.

Improve athletic performance, for both elite and more “casual” exercisers.

Focusing on the way one breathes also promotes mindfulness, which is wonderful topic for discussion.
