Why the 38 million Americans who live alone need a 'buddy system'

Public health experts and social scientists are urging the 38 million Americans who live alone to establish a daily 'buddy system' check-in protocol, a recommendation emerging from recent studies on social isolation and its health impacts. This call to action, gaining traction across the United States, is driven by growing concerns over the mental and physical risks associated with chronic loneliness, which have been exacerbated by modern living patterns and the lingering effects of pandemic-era social distancing. The recommendation is simple yet profound: individuals residing solo should commit to contacting the same trusted person—a friend, family member, neighbor, or fellow solo dweller—every single day. This contact, whether a phone call, text message, or brief visit, serves as a vital lifeline and wellness check. The consistency of the 'same someone' is crucial, as it builds routine, accountability, and a deeper mutual understanding that allows either party to notice subtle changes in mood or behavior that might signal distress. This advice is grounded in substantial research linking social isolation to increased risks of depression, anxiety, cognitive decline, heart disease, and even premature mortality. For the solo-living population, which spans all age groups but is growing particularly among older adults and young professionals, such a system acts as a preventative public health measure. It transforms casual social connection into a structured, reliable form of mutual aid, ensuring that no one falls through the cracks during personal crises, health emergencies, or simply on difficult days. While not a substitute for professional care, this daily ritual fosters community resilience and provides a foundational layer of security for millions.
