Hit 100 cups of afternoon coffee this year and my sleep tracker shows it
I marked my 100th after-2pm cup on a little index card last Wednesday, and the number surprised me since I started counting back in January. My usual is a medium roast from the shop two blocks over, nothing fancy, just one cup around 3pm while I get paperwork done. What got me was digging into my sleep app and seeing my deep sleep drop from 90 minutes a night to 68 on the days I drink it. Has anyone else tracked what afternoon coffee does to their sleep numbers, or is that just me being nosy with the app?
Wait, 22 minutes gone from your deep sleep? That's a huge drop for one 3pm cup, and it's not like you're chugging espresso at 8pm either. Caffeine hangs around in your body for hours, so a medium roast at 3 could still be half in your system by 9 or 10. That index card idea is oddly brilliant though, kind of makes me want to count my own cups.
