Want to Stay Up? Stay Hungry!
Food will just make you tired.
If you’ve ever had to stay late (or very late) at work to finish a project, those repeat trips to the vending machines aren’t doing you much good –in more ways than one.
Contrary to what a lot of us might think, sugary snacks don’t give us a burst of energy. Instead, they actually slow us down by making us sleepier.
“From an evolutionary perspective, this makes sense,” study co-author Matt Thimgan, a Washington University postdoctoral researcher, told LiveScience. “If you’re starving, you want to make sure you’re on the top of your game cognitively, to improve your chances of finding food rather than becoming food for someone else.”
Researchers reached their t conclusion after studying fruit flies that had been genetically programmed to be “sensitive to sleep deprivation,” according to LiveScience. One group, deprived of food, stayed awake longer, while the other insects that ate fell asleep sooner. The flies who didn’t get food also lived three times as long as the insects in the other group, according to the website.
But the researchers also cautioned that this doesn’t mean you should skip dinner and try to stay up all night: No research on humans has been done yet. In other studies, lack of sleep has been linked to obesity, diabetes and heart disease. (LiveScience)
