A new study reveals that consciously altering breathing rhythms can significantly influence decision-making by impacting both heart and brain activity. Researchers from the German Institute of Human Nutrition Potsdam-Rehbruecke (DIfE) and Charité -- Universitätsmedizin Berlin discovered that extending exhalations increased heart rate variability and enhanced the brain's responsiveness to rewards, correlating with a tendency towards bolder choices. This research challenges the traditional perspective that decision-making is exclusively a brain-centric process, proposing instead that signals from other bodily parts actively shape brain activity and subsequent choices. The study involved 41 healthy participants making risky decisions under controlled breathing conditions, either at their normal pace or with extended exhalations. Scientists meticulously measured brain activity using fMRI, alongside heart rate, breathing patterns, and other physiological responses. The results demonstrated that longer exhalations not only slowed heart rate but also promoted riskier choices, primarily by increasing focus on potential rewards rather than reducing concern over losses. Specific brain regions, including the ventromedial prefrontal cortex and precuneus, showed heightened activity. These findings underscore the transformative potential of breath-based interventions, suggesting that the interplay between breathing and cardiac dynamics makes the brain more receptive to positive outcomes. Researchers believe controlled breathing, being simple and inexpensive, could serve as an effective tool for everyday self-regulation. It also holds promise as a supportive, non-pharmacological strategy in clinical settings for conditions like anxiety or depression, and may even influence food-related decisions in the future.
