Nasal breathing is associated with improved memory recall and overall cognitive function compared to mouth breathing.

“bet I'm a big proponent of nasal not mouth breathing whenever possible for um many health related Reasons”

“that nose breathing is great for your health relative to mouth so I think it's also good for your cognition not only for your your dental health”

“I'm struck by how convincing the data are about nasal breathing improving brain function there were a couple studies that showed that if people either mouth breathe or nasal breathe in a laboratory study um the nasal breathers have better memory recall”

“focus on nasal breathing while doing any kind of focused work that doesn't require that you speak or eat or ingest something. There is a separate paper published in the journal of neuroscience that showed that indeed if subjects human subjects are restricted to breathing through their nose, they learn better than if they have the option of breathing through their mouth or a combination of their nose and mouth.”

“As people get older and their cognitive function goes, they tend to become mouth breathers. >> That's interesting. >> They're having trouble oxygenating their brain.”
