A recent study shows that a lack of nutrition variety may affect sleep schedules.
According to Today.com, the study shows those who slept the least lacked protein, carbohydrates and nutrients such as iron, zinc and selenium.
"People have talked about the relationship between diet and sleep for ages, but there's very little data on these connections," said Michael Grandner, PhD, a member of the Center for Sleep and Circadian Neurobiology at the University of Pennsylvania. They both touch every system in the body, and the body depends on both of them to keep working. That they interact isn't surprising--but how they interact might be."
Though correlations were found during the study, there is no certainty to the idea that nutrition and sleep affects sleep in such a manner.
"It's simple: A healthy diet helps your body work better, and as a result, sleep better too," Grander said.
