How can I improve my reaction time?

Running 5 minutes of simple RT tests before a real test session reduces variability by ~15% and lowers mean scores. Motor systems need activation like muscles do.

20–30 minutes of deliberate practice daily drives neural adaptation. Studies show 15–20ms improvements over 4–6 weeks. Use the Reaction Time test as your baseline.

100–200mg of caffeine reduces simple RT by ~10ms on average. Peak effect occurs 45–60 minutes post-consumption. Effect disappears with tolerance; works best on non-daily users.

A single night of poor sleep adds ~50ms to mean reaction time. Consistent 7–9 hours is more impactful than any supplement or training hack.

Playing fast-paced FPS or battle royale games for 20+ hours has been shown in controlled studies to improve RT by 10–15ms. The improvement transfers to lab tasks.

Learning to recognize cues that precede a stimulus reduces effective RT significantly — this is legal in all real-world contexts (driving, sports) and what top athletes train.
