A new study from the German Institute of Human Nutrition Potsdam–Rehbruecke (DIfE) and Charité – Universitätsmedizin Berlin shows for the first time that targeted control of human breathing rhythm can influence decision behavior by modulating heart and brain function. The research team led by Prof. Soyoung Q Park was able to demonstrate that prolonged exhalation increases heartrate variability and brain’s reward sensitivity, thus enabling us to make bolder decisions. The study was published in the journal Neuron.
