Past studies have suggested that eating just before you crawl into your double bed isn't good for your body, but a new study has claimed to shed more light on the relationship between our appetite for food and quality of sleep. A study conducted by researchers from the Department of Neuroscience at Uppsala University in Sweden (published January 18th) found that not getting enough sleep can actually increase an individual's appetite and, as a result, their risk of obesity down the line. The researchers examined the brains of 12 normal-weight males, using a magnetic imaging technique. They showed them pictures of various foods after a normal night of sleep and once again after a sleepless night. The regions of the brain which alert us to feeling hungry were found to be influenced by acute sleep loss - with more activity taking place in these areas when respondents were tired. Christian Benedict, a lead researcher of the study, urged individuals "to sleep about eight hours every night to maintain a stable and healthy body weight".
