Combine the restorative power of a short rest with the stimulating effects of caffeine for a powerful boost. This counterintuitive method works by taking advantage of your brain's natural chemistry. A short nap clears out adenosine, the chemical that makes you feel sleepy. By drinking coffee right before you lie down, the caffeine arrives in your brain just as you wake up, ready to block the remaining sleep-inducing receptors more effectively. The result is a sharper, more alert you.
