India, Jan. 7 -- A poor night's sleep may lead to a groggy morning-but it could also reveal much more about your long-term health. Researchers at Stanford Medicine have developed an artificial intelligence model capable of predicting a person's risk of developing more than 100 health conditions from just one night of sleep.

The model, named SleepFM, was trained on nearly 600,000 hours of polysomnography data from 65,000 participants. Polysomnography, the gold standard in sleep studies, records a wide range of physiological signals-including brain activity, heart rate, breathing patterns, eye and leg movements-while participants sleep in a lab.

"Sleep studies capture an extraordinary amount of physiological data over eight hours," said E...
