Researchers from German institutions have published findings indicating that conscious manipulation of breathing patterns can influence decision-making by affecting both cardiac and neural activity. The study, conducted by Prof. Soyoung Q Park and colleagues at the German Institute of Human Nutrition Potsdam-Rehbruecke and Charité — Universitätsmedizin Berlin, examined how extended exhalations alter the brain’s processing of potential outcomes and risks.
The investigation involved 41 healthy participants who performed decision-making tasks while following controlled breathing instructions. Participants either maintained their normal breathing pace or adopted a slower pattern with extended exhalation phases using a 2:8 inhale-exhale ratio. Researchers simultaneously monitored brain activity through functional magnetic resonance imaging while tracking breathing patterns, heart rate, skin conductance, and pupillary responses to create a comprehensive physiological profile.
Results demonstrated that extended exhalation reduced heart rate and was associated with riskier choices. The findings suggest this shift emerged from increased sensitivity to potential rewards rather than decreased concern about potential losses. Brain imaging revealed heightened activity in regions associated with reward processing and heart rate regulation, including the ventromedial prefrontal cortex and precuneus.
The research contributes to growing evidence supporting neurovisceral models, which propose that physical states substantially influence cognitive processes. Given that controlled breathing is simple, accessible, and inexpensive, researchers suggest it could serve as a practical self-regulation tool. Potential clinical applications include use as a non-pharmacological intervention for conditions like anxiety disorders and depression that involve disrupted autonomic regulation.
Future investigations will explore whether these effects extend to clinical populations and specific behavioral contexts. Researchers express particular interest in whether breathing techniques could influence food-related decisions, since eating behavior involves both reward assessment and physical state regulation. Such applications could help individuals more consciously manage dietary choices and behaviors.
