Breathing through the Nose Aids Memory Storage

Respiration modulates olfactory memory consolidation in humans. The Journal of Neuroscience, 2018; 3360-17 DOI: 10.1523/JNEUROSCI.3360-17.2018

The way we breathe may affect how well our memories are consolidated (i.e. reinforced and stabilised). If we breathe through the nose rather than the mouth after trying to learn a set of smells, we remember them better, researchers at Karolinska Institutet in Sweden report in The Journal of Neuroscience.

Research into how breathing affects the brain has become an ever-more popular field in recent years and new methodologies have enabled more studies, many of which have concentrated on the memory. Researchers from Karolinska Institutet now show that participants who breathe through the nose consolidate their memories better.

“Our study shows that we ...
