AI cracks the sleep code: one night predicts 130 diseases

As of May 2026: Co-senior author of SleepFM study published in Nature Medicine

Stanford researchers trained an AI on 600,000 hours of people sleeping. SleepFM analyzes brain waves, heartbeats, and breathing from a single night and predicts your risk for 130 diseases—dementia, heart attacks, cancer, mental disorders—with over 80% accuracy. The breakthrough turns a night of sleep into a comprehensive disease-screening tool.
