Nasal breathing vs. mouth breathing-does one help better with memory?

A new article reported in the Journal of Neuroscience concluded that breathing through the nose results in improved memorization abilities versus breathing through the mouth.  The study was conducted at the Karolinska Institute in Stockholm, Sweden which is world-renowned in the area of neuroscience and neurology.

Breathing through the nose is also healthier because it eliminates respiratory irritants such as dust and other pollutants from retracting the lungs.
