In a first-of-its-kind study, the researchers at the Karolinska Institute in Sweden have found that breathing through nose rather than the mouth boosts memory consolidation, the stage in which memories are reinforced and stabilized for subsequent retrieval.

As part of the experiment, 24 participants were presented with 12 different fragrances in the first session and then asked to relax for an hour, which is the memory consolidation period, breathing either through nose or mouth, notes Science Daily.

In the second session, the participants were exposed to a different set of 12 fragrances and asked to recall if the scent was new or old. The participants, who had mouth tapes strapped, could remember correctly almost twice as many times as those who didn’t inhale through nose, reports Mail Online. The results lay credence to the notion that respiratory cycles modulate cognitive function and have direct impact on consolidation of episodic events.
