Acute sleep loss in preschool-age children prompts increased eating and could lead to childhood obesity and a lifetime of adverse habits, according to a study led by University of Colorado Boulder researchers. The study found young children consumed 21 percent more kilocalories, 25 percent more sugar and 26 percent more carbohydrates on a day of sleep restriction. On days where children recovered their lost sleep, they ate 14 percent more kilocalories and 23 percent more fat. “Our findings suggest that sleep restriction in early childhood may promote risk for weight gain and, thus over time, the development of childhood overweight and obesity,” the study published in the Journal of Sleep Research found.
