How much sleep did you get last night? If the answer is “not enough” you’re hardly alone. According to Gallup’s estimates, almost half the people you’ll run into today are suffering from some level of sleep deprivation.
We often dismiss a little morning fatigue as an inconvenience, but here’s the reality. Missing sleep worsens your mood, weakens your memory, and harms your decision-making all day long. It scatters your focus, prevents you from thinking flexibly, and makes you more susceptible to anxiety. (Ever wonder why problems seem so much more overwhelming at 1:00am than in the first light of day? It’s because our brains amplify fear when we’re tired.) When we arrive at work sleepy, everything feels harder and takes longer. According to one study, we are no more effective working sleep-deprived than we are when we’re legally drunk.
