Time-restricted feeding can alleviate excessive dark-phase sleepiness, scientists discover

by Zhejiang University  Sleep-wake transition-related firing in the PVT is disrupted by AL HFD feeding. Credit: Zhejiang University Obesity induced by a high-fat diet (HFD) is a growing epidemic and major health concern. While excessive daytime sleepiness (EDS) is a pervasive symptom of HFD-induced obesity, research findings suggest that reduced wakefulness could be improved by...
