Yes! Science-approved: Coffee naps

Here’s one that we cannot not pass on: the power of the coffee nap. Via Vox:

If you’re feeling sleepy and want to wake yourself up — and have 20 minutes or so to spare before you need to be fully alert — there’s something you should try. It’s more effective than drinking a cup of coffee or taking a quick nap.

It’s drinking a cup of coffee and then taking a quick nap. This is called a coffee nap.

To understand a coffee nap, you have to understand how caffeine affects you. After it’s absorbed through your small intestine and passes into your bloodstream, it crosses into your brain. There, it fits into receptors that are normally filled by a similarly-shaped molecule, called adenosine.

But here’s the trick of the coffee nap: sleeping naturally clears adenosine from the brain. If you nap for longer than 15 or 20 minutes, your brain is more likely to enter deeper stages of sleep that take some time to recover from. But shorter naps generally don’t lead to this so-called “sleep inertia” — and it takes around 20 minutes for the caffeine to get through your gastrointestinal tract and bloodstream anyway.

So if you nap for those 20 minutes, you’ll reduce your levels of adenosine just in time for the caffeine to kick in. The caffeine will have less adenosine to compete with, and will thereby be even more effective in making you alert.

Then it’s off to your best Ashtanga practice ever.
