Does Your Nose Run Your Brain?

Every breath through your nose is quietly setting the rhythm of your brain — tuning memory, fear and focus. The hidden link between breathing and the brain. You breathe about 20,000 times a day and never notice. But each nasal inhale synchronizes electrical waves across your memory and emotion centers — and breathing through your nose instead of your mouth measurably changes how well you remember and how fast you react to fear. Here's the strange science of the nose-brain connection, and how you can grab the wheel. SOURCES • Zelano et al. (2016).
