The idea is that you drink a coffee, then take a quick 20-minute nap and by the time you wake up, your caffeine has kicked in and you’ve got all the energy.
Coffee naps like this make sense because it takes about 20 to 25 minutes for caffeine to work its way through the bloodstream. So if you knock back a latte and take a 20-minute snooze, you’ll get a double boost.
