Across the US and UK, research consistently links loneliness to higher service use, and during COVID-19 Google searches for “loneliness” rose measurably while a UK study found people were 1.4 times more likely to seek primary care, with meta-analysis showing that social connection interventions can reduce loneliness and potentially lower health service demand.
