Reset your 2 PM drowsiness with a 15-minute deep nap + a quick walk
If it were me, I’d start by proposing a 15-minute solid nap. Set a timer, slip on an eye mask and earplugs to fall asleep quickly, and when you wake up, drink a glass of warm water or coffee. Before returning to your desk, take a 1–2 minute brisk walk in the hallway to raise your heart rate and wake yourself up—that would be my recommended set routine.
