How is the brain affected from sleeping less?

ANSWER

Skimping on sleep sets your brain up to make bad decisions. It dulls activity in the brain’s frontal lobe, the locus of decision-making and impulse control.

So it’s a little like being drunk. You don’t have the mental clarity to make good decisions.

Plus, when you’re overtired, your brain's reward centers rev up, looking for something that feels good. So while you might be able to squash comfort food cravings when you’re well-rested, your sleep-deprived brain may have trouble saying no to a second slice of cake.
