Study Overview
Brief Summary
The purpose of this study is to determine if drinking a hot cup of coffee immediately before taking a 20-minute nap (the "Caffeine Nap") reduces the standard "grumpiness index" upon waking compared to drinking decaffeinated bean-water.
Detailed Description
Participants will be randomized 1:1 to either the intervention group (active caffeine) or the control group (decaf). Participants will be forced to consume 8 ounces of the assigned beverage at a temperature of exactly 140°F (60°C) within a 2-minute window, and then immediately instructed to "go to sleep" in a room filled with aggressive ticking clocks.
Upon sudden waking via a loud air horn at minute 20, participants will immediately complete the validated "Am I Mad at the World?" Visual Analog Scale (VAS).
