Average Reaction Time
The average human visual reaction time is around 200–250ms. Trained athletes often react in 150–180ms, while some gamers achieve under 150ms.
🧠
What Affects Reaction?
Fatigue, age, caffeine, and practice all influence reaction time. Younger adults tend to react faster, and sleep-deprived people can be 10–15% slower.
📊
Improve Your Speed
Regular practice, reaction-based games, proper sleep, and physical exercise all help improve your reaction time over weeks and months.
