Daniel Pink has been a wise futurist time and time again, from the motivation-focused Drive to the gig-economy-predicting Free Agent Nation. In his new bestseller, When: The Scientific Secrets of Perfect Timing, he has a new innovation called the nappacino, which could innovate the coffee industry. Here he is explaining it on the Success Talks podcast:

The ideal length of a replenishing nap... is 10-20 minutes. To turbo charge it, you can take a performance enhancing drug: Have a cup of coffee, then take a 20-minute nap. It is a nappacino. It takes about 20-25 minutes for that caffeine to get through your blood stream, so when you're waking up from that ideal 20 minute stretch, you get a double boost. Nappacino! I'm guessing Starbucks is going to have little napping station soon.

Yes, it really works

Nearly two years ago, the hotel chain Swissotel shared a great infographic on napping. One of the biggest highlights? The so-called coffee nap. Here's what I said at the time:

Do coffee to ease heavy napping: Called a coffee nap, drink caffeine right before you lay down to help limit how long you sleep. Late day coffee is recommended, anyway.

I've been a dedicated napper since grad school and, more recently, coffee has become part of my routine (especially after becoming a stay-at-home dad). Pink's term nappacino is the perfect description - and it has been backed by both personal experience as well as science.

What's next for Starbucks

Coffee nap rooms are already happening: Siesta and Go recently opened in Madrid, Spain, and there are other smaller, less notable coffee houses that have ad hoc cots and couches for sleepy customers.

Remember that extra roasted (too much for some tastes) Starbucks coffee was inspired when visionary and twice-over CEO Howard Schultz got inspired in Milan, Italy.

Starbucks is relentlessly looking to innovate, from changing the coffee formula to, most recently, opening up a cashless store in Seattle (a trend you see at smaller coffee chains in San Francisco) . Don't be surprised if you see little airport-style napping pods at your favorite Starbucks - and you'll likely have Daniel Pink to thank for it.
