The number one health practice in the world, you guessed it, is sleep. In a study of army sharpshooters, if someone requires seven hours of sleep and they instead get six, their accuracy in the range goes down from 90% to approximately 50%. Even an hour loss of sleep can take down your brain's ability to think, to analyze, to process data. So if you force yourself to wake up earlier than you need because you need to rush into work, know that your work that day is going to be significantly lower quality than if you simply gave yourself a good night's sleep. Never, ever compromise sleep. Your brain needs it.
