Cardiorespiratory resonance — warmth in love and pride; aching constriction in grief and anxiety
Across 101 countries (Nummenmaa et al., 2014 PNAS; Volynets et al., 2020), the anterior chest and sternal wall show the highest statistical convergence of any human body region — expanding with warmth during love, joy, and pride, while constricting sharply during grief, heartbreak, panic, and social rejection.
