Our research, surveying over 2,000 American adults, reveals that nearly one in three often or always feel lonely. This emotional isolation is linked to a surge in fatigue, insomnia, and pain seen in primary care, yet stigma and poor access to mental health support remain major barriers to care.

The data shows that living with others does not guarantee protection from loneliness; instead, meaningful emotional connection is the crucial factor. These findings highlight the need for integrated care approaches that address loneliness as a core health measure, bridging mind and body for better outcomes.
