Overview

• In PLOS Biology, researchers used Human Connectome Project data to define five reproducible sleep‑biopsychosocial patterns tied to behavior and health.
• Profiles linked poor self‑reported sleep to higher depression and anxiety, while short sleep duration correlated with slower reactions and weaker cognitive performance.
• The team found a profile marked by sleep‑aid use associated with worse visual memory and emotion recognition despite higher reported satisfaction with social relationships.
• Each profile showed a unique neural signature at rest, indicating that variability in sleep relates to differences in brain network organization.
• Participants scored across all profiles rather than fitting into a single type, and the young, primarily white sample and cross‑sectional design limit generalizability and causal claims.
