Overview
- Researchers delineated five sleep-biopsychosocial profiles — poor sleep and mental health, sleep resilience, sleep aids and sociability, short sleep with cognitive impact, and disturbances with mental‑health ties.
- The study drew on Human Connectome Project data from 770 healthy adults, combining sleep questionnaires and 118 biopsychosocial measures with resting‑state fMRI, and found profile‑specific brain network organization.
- The poor‑sleep profile reported the worst subjective sleep along with higher stress, anxiety, depression, anger and fear.
- People sleeping fewer than six to seven hours performed worse on tasks involving problem‑solving and emotional processing and showed higher aggression and irritability.
- A medication‑using group reported better daytime functioning and social support but showed weaker emotion recognition and memory, and experts say clinical use of these profiles awaits replication and longitudinal validation.
