The Nappuccino method is a popular productivity technique that combines a short nap with caffeine intake to improve alertness and mental performance. Often associated with sleep expert Dr. Cheri Mah, the Nappuccino technique typically involves drinking coffee quickly before taking a 30-minute nap, allowing the caffeine to kick in around the time you wake up. She talks about it here on Think Fast Talk Smart Podcast, where Matt Abrahams explores high-performance habits and mental clarity techniques with her. The idea behind a Nappuccino is to combine the restorative effects of a power nap with caffeine for a sharper, more energized state afterward.
