The human body is a miracle. But that doesn't mean we shouldn't always be finding ways to game the system to gain a little bit more of an advantage. We've previously shown you how to hack your brain into overdrive and pointed out that your body hides all sorts of secret powers from you . You just have to know how to make it give up its secrets.

5 Drink a Cup of Coffee Before a Nap -- You'll Feel Better

Imagine you're pulling an all-nighter trying to meet a deadline, or driving all night trying to figure out which warehouse the Joker stashed Harvey Dent in -- whatever the case, you're incredibly tired and sleep is not an option. Traditionally you'd either take a nap or have some coffee (or a urine-staining energy drink), but it's one or the other -- either try to get a quick nap, or power through on a chemical high.

Or "highs."

But science, true to form, took these two seemingly contradictory options and decided to merge them together, like when WCW invaded the World Wrestling Federation. And it worked, and not in the order you'd expect.

Researchers found that a cup of coffee followed by an immediate 15-minute nap is a notably more effective method of staying awake and alert for longer than either coffee or a nap alone. Which is a bit odd when you think about it, since you'd expect the caffeine to keep you awake, leaving you teetering on the edge of falling asleep but not quite going over (this is known in the scientific community as the Edward Norton-Brad Pitt boundary). But the trick to the "caffeine nap" is that caffeine doesn't act immediately -- it takes about 45 minutes to be completely ingested, but the effect of the drug kicks in after only 15 minutes.

Which is why we recommend injecting grizzly bear adrenaline into your first cup of the morning.

See, what caffeine actually does is block your brain's ability to respond to adenosine, a chemical that builds up in your bloodstream the longer you're awake. The more adenosine you have in your body, the more your brain tries to get you to sleep. So by drinking coffee (or soda or a nice can of BAWLS) and then diving directly into bed, you can sleep for 15 minutes and get the regular restorative effects of a nap. By the time you wake up, the caffeine you've ingested is swimming in your bloodstream and dulling the effects of adenosine, stabbing your tiredness in the face.
