Reaction time is the time between a stimulus appearing (like a green light) and your response (pressing a button). It's measured in milliseconds (ms). A reaction time of 200ms means 0.2 seconds — which feels instant but actually involves a complex chain: your eyes detect the signal → optic nerve fires → visual cortex processes it → motor cortex sends a command → your muscles contract.
This entire process is what reaction time tests measure. Faster times mean faster neural processing — a direct indicator of cognitive alertness.
| Age Group | Average Reaction Time | Rating |
|---|---|---|
| 10–14 years | 270–350ms | Average |
| 15–24 years | 200–260ms | Best Years |
| 25–34 years | 210–270ms | Fast |
| 35–44 years | 230–290ms | Average |
| 45–54 years | 250–320ms | Slowing |
| 55–64 years | 280–360ms | Slower |
| 65+ years | 320–420ms | Slowest |
Research consistently shows men have slightly faster average reaction times than women — approximately 20–30ms faster on visual reaction tests. However, this difference narrows significantly with training. Trained women outperform untrained men in every study.
The gender gap in reaction time is largely explained by differences in sport participation and physical training history, not biological neural speed. A woman who regularly trains attention and reaction speed will comfortably outperform an untrained man.
Makes it faster: regular exercise, adequate sleep, caffeine (moderate amounts), warm-up/practice, regular cognitive training
Makes it slower: sleep deprivation, alcohol, aging, sedentary lifestyle, stress, illness, hunger
Sleep deprivation is the single biggest reaction time killer. A person who has been awake for 24 hours has reaction times equivalent to a person with 0.10% blood alcohol — legally drunk in most countries.

Under 200ms is fast. Under 150ms is exceptional. Professional esports players average 150–180ms. The world record is approximately 101ms.
Yes — it peaks around age 24 then gradually increases. By age 60, average reaction time is 25–50ms slower. Regular training significantly offsets this decline.
Daily reaction time practice, adequate sleep, physical exercise, and avoiding alcohol all help. Consistent training can improve your score by 20–50ms over 4–6 weeks.
