Social connection is a fundamental, biological human survival imperative akin to hunger, thirst, or physical shelter. Differentiating Social Isolation<\/strong> (an objective, measurable lack of contact and relationships) from Loneliness<\/strong> (the subjective, painful psychological discrepancy between one’s desired and actual level of interpersonal connection). Pioneered by John Cacioppo in the Evolutionary Theory of Loneliness<\/strong> and Julianne Holt-Lunstad’s epidemiological meta-analyses, chronic loneliness is a severe biological hazard: carrying a mortality risk equivalent to smoking 15 cigarettes daily, driven by chronic sympathetic hyperarousal, systemic neuroinflammation, and hypervigilance. The Loneliness, Social Isolation and Belonging Psychoeducation Module<\/strong> provides 8 structured video lessons on evolutionary loneliness signals, cognitive hypervigilance, and authentic social connection.<\/p>\n
