First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether drinking a cup of coffee right before a 20-minute nap can reduce irritability and mental fog after waking. Researchers will compare real coffee to decaf in 50 overworked adults who tend to feel grumpy after naps. The goal is to see if the 'caffeine nap' improves mood and clarity.
