SA视讯   Fading fast and need a jolt of energy? Sure, a cup of coffee can be great for that, and studies have shown that midday naps at work are awesome for your health, but what's even better than coffees or naps? Drinking a coffee and then taking a nap.


SA视讯   It sounds really counterintuitive, because we all know caffeine messes with your ability to sleep (that's the whole point), but the trick here is that the caffeine in coffee doesn't kick in straight away.

SA视讯   这听起来真的有悖常理,(重点是)我们都知道咖啡因会影响你的睡眠,但这里的秘诀是,咖啡中的咖啡因并不会马上起作用。

  If you can strategically time your coffee and your nap, you can be unconscious for those rough few minutes that the body spends digesting the coffee, says the video from Vox above.


  And how long is that? It takes about 20 minutes for the coffee to reach your small intestine, pass into your bloodstream, and then make it to your brain.


SA视讯   So if you can time your nap to be just 20 minutes from the moment you've had your coffee, you should wake up feeling pretty great.

SA视讯   所以如果你能把午睡时间设定在喝完咖啡后的20分钟内,醒来之后你会感觉很好。

  How does this work? The reason you were feeling crappy in the first place is a molecule called adenosine in your brain that's responsible for making you feel tired.


  We produce different amounts of adenosine throughout the day - it's a by-product of brain activity, so at the end of the workday you're likely to experience a build-up of adenosine, which slows down your neurons and makes you feel tired.


  What caffeine does is block off the adenosine from binding with receptors in the brain. And this is where a nap can really help. "The great thing about coffee naps is that sleep naturally clears out adenosine from the brain. So the caffeine doesn't even need to compete with the adenosine to fit into those receptors," says the Vox video team.
