Lack of sleep makes your brain hungry
Date: 24.1.2012
New research from Uppsala University, Sweden, shows that a specific brain region that contributes to a person's appetite sensation is more activated in response to food images after one night of sleep loss than after one night of normal sleep. Poor sleep habits can therefore affect people's risk of becoming overweight in the long run.
In a new study, Christian Benedict, together with Samantha Brooks, Helgi Schiöth and Elna-Marie Larsson from Uppsala University and researchers from other European universities, have now systematically examined which regions in the brain, involved in appetite sensation, are influenced by acute sleep loss. By means of magnetic imaging (fMRI) the researchers studied the brains of 12 normal-weight males while they viewed images of foods. The researchers compared the results after a night with normal sleep with those obtained after one night without sleep.
