Not enough shuteye is linked with several health disadvantages. The latest among them, is the craving for junk food. That’s right, a study has recently revealed that sleep deprivation can make us desire junk food more than healthy food. Researchers at UC Berkeley scanned the brains of 23 healthy young adults, first after a normal night’s sleep and next, after a sleepless night by using Functional Magnetic Resonance Imaging (fMRI). The researchers measured brain activity as participants viewed a series of 80 food images and rated their desire for each of the items. Matthew Walker, the senior author of the study, found that highcalorie foods became significantly more desirable when participants were sleep-deprived.
