"Sleep eaters" binge on sugary, high-calorie snacks, sometimes 5 times a night

Consequences of nighttime eating can include injuries like black eyes from walking into a wall or hand cuts from a prep knife, or dental problems from gnawing on frozen food.

Upwards of 10 percent of adults suffer from some sort of parasomnia, or sleep disorder, like sleepwalking or night terrors. Some have driven cars or performed inappropriate sexual acts — all while in a sleep-induced fog. About 1 percent, mostly women, raid the refrigerator.
