Breathing through the nose may improve the transfer of experience to long-term memory, finds a study of human adults published in JNeurosci. The findings add to growing evidence for the influence of respiration on human perception and cognition.
Building on previous research in animals and humans, Artin Arshamian and colleagues compared the effects of nose breathing and mouse breathing during a one-hour consolidation period after participants were exposed to various odors. Nose breathers, whose mouths were taped over during the consolidation period, showed increased odor recognition compared to mouth breathers, whose noses were clipped during consolidation.
Although this study did not measure brain activity, the researchers suggest that nose breathing may facilitate communication between sensory and memory networks as memories are replayed and strengthened during consolidation. The study provides evidence that, in addition to its effects on memory encoding and retrieval, nasal respiration also supports memory consolidation.

JNeurosci, the Society for Neuroscience's first journal, was launched in 1981 as a means to communicate the findings of the highest quality neuroscience research to the growing field. Today, the journal remains committed to publishing cutting-edge neuroscience that will have an immediate and lasting scientific impact, while responding to authors' changing publishing needs, representing breadth of the field and diversity in authorship.
