This global interdisciplinary study explores love as a neurobiological, psychological, and sociological constant. Drawing on sixteen years of longitudinal mixed-method data from more than 1000 participants across 45 nations, it quantifies love’s regulatory effects on the human body and its transformative impact on societies. Physiological analyses revealed increased heart-rate variability (+36%), lowered cortisol (−31%), and elevated oxytocin (+44%) among participants who practiced compassion or service. Qualitative themes—protection, provision, presence, purpose, perseverance, and peace—emerged consistently across cultures. Sociological correlations linked national kindness indices with civic trust (β = 0.42), economic stability (β = 0.33), and reduced violence (β = −0.37). The findings demonstrate that love operates as a universal mechanism of human regulation and resilience. Clinically, compassion practices improve emotional stability and therapeutic outcomes. Sociologically, love functions as the moral infrastructure of thriving communities. Rooted in compassion neuroscience, trauma-informed care, and global cultural analysis, this research reframes love from sentiment to science—revealing it as measurable, teachable, and essential to human survival.
