A Good Night's Sleep Makes for Better Food Choices
Sleepless nights mean less-healthy breakfasts. German researchers took blood samples, observed activities, and scanned the brains of 32 healthy young men, once after a normal night’s sleep at home and a week later, after a sleepless night in the lab. Though they reported being equally hungry on both mornings, their brains and behavior told a different story. During a brain scan, the men were offered chocolate and other snacks for sale. Not only were they willing to pay more after a sleepless night, but brain regions tied to food cravings—the amygdala and hypothalamus—showed a boost in activity when participants were tired. Want to stick to healthy eating habits? Get a good night’s sleep.
