Consuming 200mg at 17:00 leaves approximately 90.8mg in your bloodstream at your 23:30 bedtime. This is equivalent to drinking a full cup of coffee right as you climb into bed. It will significantly reduce Stage 3 Deep Slow-Wave sleep, causing elevated heart rate throughout the night.

Frequently Asked Questions
What is the biological half-life of caffeine?
In healthy adults, caffeine has an average biological half-life of approximately 5.0 to 5.7 hours. If you chug a 200mg energy drink (like Ghost or Celsius) at 6:00 PM, you will still have 100mg of active caffeine in your bloodstream at 11:45 PM, and 50mg remaining at 5:30 AM.
How does late caffeine destroy next-day aim and reaction time?
Caffeine works by binding to and antagonizing adenosine receptors in your brain. While you may fall asleep exhausted, residual caffeine (>25mg) fragments your sleep architecture, suppressing slow-wave deep sleep (Stage 3 NREM) and REM sleep. This leads to brain fog, jittery hands, and 30ms-50ms slower visual reaction time the following day.
What is the ideal 'Caffeine Cutoff Time' for competitive gamers?
Sleep neurologists and sports scientists recommend consuming zero caffeine at least 9 to 10 hours before your target bedtime. If you sleep at midnight, your last sip of coffee or energy drink should be finished before 2:00 PM.
