“Tonight, while you watch this, 164 million Americans will not get enough sleep.” Sin Dormir is a 6-minute, 16-second documentary that examines the hidden toll of chronic sleep deprivation. Through a neurologist, an endocrinologist, and a neuropsychologist from the University of Miami Miller School of Medicine, the film connects insufficient sleep to cognitive decline, hormonal disruption, and deteriorating mental health. It closes not with a dramatic lifestyle overhaul, but with one simple, accessible ask: turn off the light an hour earlier.
