Researchers agree that sleeping for a little bit after drinking caffeine is more effective than just drinking caffeine or a quick nap by itself.

Adenosine is a byproduct of brain activity that makes you feel tired, but caffeine is a substance that can block sleep receptors. It takes around 20 minutes for the caffeine to get through your digestive system and into your bloodstream. If you nap for 20 minutes after quickly drinking caffeine, you’ll reduce your levels of adenosine just in time for the caffeine to kick in.

Here’s how to take a coffee nap. First, prepare a cup of coffee and set up your alarm for 20 minutes in order to make sure you wake up on time. Next, when your coffee is not too hot, drink it as quickly as possible.

Then, immediately try to go to sleep. If you cannot sleep, just make sure that you are lying down with your eyes are closed for the whole 20 minutes.
