Inhale through nose to enhance memory: Study
A recent study reveals that inhaling
through nose heightens memory and response to fearful stimuli, whereas the
effects disappear while mouth breathing.
The study was published in the Journal of Neuroscience.
According to Northwestern Medicine, the rhythm of breathing creates electrical activity in the human brain that enhances emotional judgments and memory recall. They found that individuals were able to identify a fearful face more quickly, if they encountered the face when breathing in compared to breathing out.
Individuals were also more likely to remember an object if they encountered it on the inhaled breath than the exhaled one. The effect disappeared if breathing was through the mouth.
"One of the major findings in this study is that there is a dramatic difference in brain activity in the amygdala and hippocampus during inhalation compared with exhalation," said lead study author Christina Zelano at Northwestern University Feinberg School of Medicine.
"When you breathe in, we discovered you are stimulating neurons in the olfactory cortex, amygdala and hippocampus, all across the limbic system," Zelano added.
They suggested that the amygdale- a roughly almond-shaped mass of grey matter inside each cerebral hemisphere, involved with the experiencing of emotion - is strongly linked to emotional processing, in particular fear-related emotions.
"When you inhale, you are in a sense synchronizing brain oscillations across the limbic network," Zelano noted.
