Breathing like this improves memory and focus

Practicing mindful breathing (by focusing on the depth and timing of breaths) can have powerful effects on cognition, say investigators in the journal Psychophysiology. In the study, participants tackled a tough mental task while researchers studied their breathing patterns and brain scans. The finding: Levels of brain chemicals that improve memory and focus rose when subjects were mindful of their breath. A one-minute breathing pattern that’s proven to sharpen focus: Breathe in for four counts, then exhale for six; repeat six times.
