Frequently Asked Questions
Average reaction time?
Visual stimulus: 250ms (20s), 285ms (40s), 310ms (60s). Auditory faster (~170ms). F1 drivers ~150ms. Slowest reflex = 800ms+ (chronic sleep deprivation, alcohol).
Why does reaction time slow with age?
Neural transmission speed drops ~1ms per year after 25. Combined with reduced visual processing speed. Sleep + exercise can mitigate ~40%.
How to improve?
Sleep 7-9h. Cardiovascular exercise. Reduce alcohol. Reaction-time training games. Caffeine helps short-term (-15%).
