Why we can’t resist that doughnut when we’re sleep deprived
A poor night’s sleep leaves you far more vulnerable to temptation, researchers say.
Those who fail to get enough shut-eye are more likely to opt for sweet treats like doughnuts and also gain more pleasure from them as well.
A team from Columbia University in New York found the brain’s reward centre was more likely to light up in a study participant who was looking at unhealthy food if they were sleep deprived.
Study leader Dr Marie-Pierre St-Onge said: ‘The same brain regions activated when unhealthy foods were presented were not involved when we presented healthy foods.
‘The unhealthy food response was a neuronal pattern specific to restricted sleep. This may suggest greater propensity to succumb to unhealthy foods when one is sleep restricted.’
