Take a Nap

Before there was electrical lighting, people actually slept on average, ten hours a night. These days we barely average seven hours and, as a result, we are a sleep-deprived nation. Sleep-deprived brains make mistakes. Studies show that if you shortchange your night's sleep by an hour and a half, you can lose as much as one third of your alertness the next day. And contrary to popular belief, lost sleep cannot be "made up for". A nap can improve your mood and your mental sharpness.
