A Bad Night’s Sleep May Explain Overeating

Researchers evaluated how disrupted sleep and excess food intake are correlated, placing both adults and children at risk for long-term health conditions. Study authors reported that, after a bad night’s sleep, the appetite-controlling hormone is impacted, emotional stress is higher, and more food is desired to compensate for the lack of energy and increased impulsivity, which affects the amount of food consumed in a day. Some studies have also showed that after limited sleep, neural activation in the orbitofrontal cortex was higher in response to food images vs. non-food images. Also, people with disrupted sleep patterns had higher response levels to the rewarding values of food. Journal of Health Psychology May 2015
