Afternoon Coffee and Sleep Latency
Afternoon coffee and sleep latency stay coupled through long caffeine half-life—late cups stretch time to fall asleep before total hours look bad on trackers.
Afternoon coffee and sleep latency are linked through caffeine's six-hour half-life—3 p. m.
drip can still blunt deep sleep at 11 p. m.
even when you feel sleepy on cue. Latency stretches before total sleep time drops, so wearables catch the hit before you do.
Shift hard thinking coffee earlier and use a walk or protein snack for the 3 p. m.
slump instead of a second espresso.
Common questions

Why can you fall asleep after afternoon coffee but still feel tired?
You may lose deep sleep and REM efficiency while total hours look okay. Compare latency and recovery scores, not only time in bed, when judging afternoon cups.
