What is a Nappuccino?

A "Nappuccino" refers to a practice that involves drinking a cup of coffee or a double espresso, followed by taking a nap, typically in the afternoon. The concept behind it is that the caffeine will hit your system as you wake up from the nap, thereby enhancing focus and exercise performance. However, Andrew Huberman expresses concerns about the Nappuccino trend because it usually involves ingesting caffeine in the afternoon, which can disturb sleep patterns. He recommends instead using non-sleep deep rest protocols (NSDR) for benefits like mood, focus, and alertness without the need for caffeine, as caffeine intake prior to rest can reduce the effectiveness of both a nap and NSDR in restoring natural levels of alertness and focus 1.
