So, if you regularly get 6 hours – listen up. Researchers found people who slept 6 hours a night for 2 weeks functioned as poorly as people who stayed awake for two days straight. And the sleep-deprived people had NO IDEA they weren’t functioning properly. They thought they were perfectly fine. Basically, our sleepy brain is in denial! But that lack of sleep makes us eat more, act more emotionally, worry more, drive poorly, make more mistakes at work, and makes us 400% more likely to get sick! So don’t trust yourself to know whether you’re sleep-deprived, trust the clock. And if you’re getting only 6 hours, find a way to get more.
