Acute sleep deprivation leads to increased food intake leads
Acute shortening of sleep duration in an increase in hunger in the morning and evening. In a crossover study of 12 normal-weight men, the sleep duration for a night of 8 hours reduced to 4 hours, while the recovery time was two hours earlier (ie, 6 instead of 8 clock clock). The total energy intake on the day after 4 hours of sleep was higher by 22% than under normal sleep duration and was significantly higher than the small additional increase in energy expenditure caused by the prolonged period of wakefulness. Contrary to previous study results of sleep deprivation increased but also the physical activity of the subjects, the associated energy expenditure is not compensated, however, the increased energy intake.
Repeated sleep deprivation could lead to long-term data indicated an increase in weight and thus represents a risk for the development of obesity dar.
