Social Health Trends & Predictions: Connection is the New Frontier

In this SXSW 2026 keynote, social health expert Kasley Killam returns after her 2025 opening keynote to present the latest breakthroughs, trends, and predictions shaping the growing social health movement. She opens by defining social health as the third essential pillar of overall well-being alongside physical and mental health — a dimension grounded in connection, relationships, and community. Killam argues that for too long, the profound impact of relationships on health outcomes has been subsumed under the mental health umbrella, when in fact the evidence base is far broader: people with strong social relationships enjoy fewer depressive symptoms, stronger immune responses, better cognitive function, lower risk of heart disease, and longer lifespans. The OECD estimated in 2024 that loneliness and lack of regular social interaction account for up to 871,000 premature deaths per year, and people lacking strong family ties are up to 53% more likely to die from any cause.

Killam presents multiple signals that social health is crossing from niche to mainstream. Google searches for 'social health' reached an all-time high globally, academic publications on the topic continue to multiply, and in June 2025 the World Health Organization published a landmark report declaring social health the 'missing pillar' — formally validating the framework Killam has championed for years. The VML Future 100 report, drawing on 15,000+ survey respondents and 60+ expert interviews, declared social health one of the top global trends shaping industries and culture in 2026, stating: 'The next trillion dollar wellness economy is built on connection.' Using the diffusion-of-innovation curve, Killam argues the field is right at the tipping point where innovators and early adopters give way to the early majority.

The data picture on actual social health outcomes is mixed. In the US, 16% of Americans feel isolated or lonely all or most of the time; 67% never participate in clubs or organizations; and a striking 20% spend in-person time with people they care about (outside their household) only zero, one, or two times per year. Over the past 20 years, time spent hosting or attending social events has declined by 50%, and the share of people who saw family and friends daily worldwide has also dropped. Generationally, the share of people who ate daily meals with their families has fallen from 84% among the Silent Generation to just 38% among Gen Z. On the positive side, one in two US adults say they hardly ever feel lonely, 72% feel a sense of belonging in their community, and 90% of people globally say they have someone to rely on. Meanwhile, Google searches in early 2026 for 'how to make friends,' 'friend app,' 'social clubs,' and 'community events' are all at all-time highs — signaling hunger for connection.

Killam identifies four priority arenas for social health innovation: schools (mandating social health skills alongside physical education), the workplace (every team needs an internal social health strategy — only one audience member had one), the online world (AI companions are being embraced by 49% of Gen Z, with 37% open to falling in love with AI; she proposes a traffic-light framework — green if AI supports human relationships, yellow if it supplements, red if it substitutes), and local communities (grassroots and hyperlocal initiatives like the Super Neighbors in Paris are often more effective than tech solutions). She closes with a call to action: as social health makes the same transition that mental health made over the past two decades — from stigma to mainstream industry — leaders must steward that transformation with integrity and compassion, grounding the emerging market in evidence and ethics rather than exploiting the need for profit.
