You are feeling tired and you wonder if you should take a nap or drink coffee?

Here comes the “coffee nap” (drinking coffee followed immediately by a short nap) and, according to a few, new, brain studies, it may be the best solution to beating fatigue.

The reason? Effectively timing the interplay of caffeine molecules with adenosine receptors in the brain and sleep causes the caffeine to work better at keeping you alert once you wake up.

It’s important that the nap be short: only 15-20 minutes max. It’s OK if you don’t fall asleep: just resting in a calm, tranquil, quiet environment has the same effects. But you have to drink the coffee relatively quickly, or it will mess up the timing of the reaction.
