Caffeine Timing Cognitive Performance
Caffeine timing cognitive performance schedules coffee for alertness without stealing sleep—often delaying the first cup and ending by early afternoon.
Caffeine timing cognitive performance balances alertness benefits against jitters, anxiety, and sleep erosion. Effects peak roughly thirty to ninety minutes after intake; half-life stretches afternoon cups into night insomnia.
Delaying the first dose ninety minutes after waking can reduce afternoon stacking for some people. Pair with food to blunt gastric upset.
Genetic slow metabolizers need earlier cutoffs. Count all sources—tea, cola, pre-workout—not coffee alone.
