The ‘nap a latte’ technique: How espresso and a fast nap might recharge you for 4 hours
A cup of espresso adopted instantly by a brief nap might sound counterintuitive. However sleep skilled Dr. Michael Breus says the mix can restore alertness for hours when used appropriately.

Breus mentioned one key issue behind that feeling is adenosine, a compound that builds up within the mind over time. As adenosine accumulates, he mentioned, “you get sleepier and sleepier and sleepier.”
That’s the place caffeine enters the equation. Based on Breus, caffeine is structurally related sufficient to adenosine that it might probably bind to the identical receptor websites and block additional buildup.
His advisable technique is straightforward: drink a cup of drip black espresso rapidly, then take a 25-minute nap instantly.
“The adenosine that is constructed up in your mind will burn by whilst you’re napping,” Breus mentioned. “Caffeine, since it is so shut in molecular construction, can match into that receptor website. It blocks any new adenosine. You are good for 4 hours, assured.”
He mentioned he makes use of the method, which he calls a “nap-a-latte,” with executives who must get better rapidly after poor sleep earlier than an necessary assembly or presentation.
Breus additionally addressed why espresso doesn’t intervene with the nap itself. Many individuals assume caffeine works immediately, he mentioned, however that isn’t the way it operates within the physique.
“It has to go down, has to get absorbed, needs to be digested,” he mentioned, including that the method normally takes about 25 to half-hour. That window permits time for a brief nap earlier than the stimulant impact begins.
He gave an instance of somebody who slept solely 4 hours and feels exhausted at 2 p.m. In that case, the temporary nap might scale back sleep strain, whereas caffeine helps forestall extra adenosine from binding afterward.
The end result, he mentioned, is a pointy elevate in power ranges with no lengthy sleep break.
Dr. Breus is a medical psychologist, a Diplomate of the American Board of Sleep Medication, and the creator of books together with Sleep Drink Breathe.
