If you’re exhausted, and someone asks how you’re doing, lie and say, “I’m great!” Researchers at the Cleveland Clinic found that can actually trick your brain into thinking you DO feel great and rested. It’s called “placebo sleep”… and – just like taking a fake placebo pill fools us into feeling better – pretending you slept well is so effective, it can help you power through the day even when you’re short on sleep.
