'Coffee Naps' Just Might Change Your Life

Here's Why Having caffeine just before a short snooze is the ultimate energy hack.

The words "coffee" and "nap" don't usually go together. But a strategy that pairs the two actually makes sense—and could be the energy boost you need to make it through a crazy day.

A coffee nap is exactly what it sounds like: You drink a cup of joe, then immediately take a snooze. While this may seem counterintuitive, the caffeine in coffee doesn’t kick in for about 30 minutes, so dozing off just after you drink your java is very possible. And that short sleep will provide its own energy punch: Power naps have been shown to improve alertness and performance.
The ideal coffee nap is 30 minutes long, which means you're waking up just as the caffeine starts to work its magic.

The result: You feel both rested and stimulated.
