Are you a nose or a mouth breather?
According to a study published in the Journal of Neuroscience in 2018, those of us who breathe through our noses may remember things better. After sampling a dozen different smells, researchers asked half of the study’s participants to breathe for one hour through their noses. The other half, of course, breathed through their mouths. Their results exhibited that those who breathed through their noses were able to recall the initial smells better than their mouth-breathing counterparts.
“This demonstrates, first, that nasal respiration is important during the critical period where memories are reactivated and strengthened,” write the study’s authors. “Second, it suggests that the neural mechanisms responsible may emerge from nasal respiration.”
Its better to inhale through your nose as this faculty is closer linked to our brain’s memory function than our mouth
