What Is Reaction Time? A Guide to Speed and Performance

In sports, driving, or even daily life, your ability to respond quickly to a stimulus can make a huge difference. 

This ability is called reaction time. But what is reaction time, what’s considered average, and how can you improve it? Let’s break it down.

Reaction time is the period between the presentation of a stimulus (something you see, hear, or feel) and your body’s response to it. 

For example:

• A sprinter hearing the starting gun and beginning to run.

• A driver pressing the brakes after seeing a red light.

• A goalkeeper diving to save a shot.
  
  

When people ask what is time reaction, they’re referring to the same concept—how long it takes your brain and body to process and respond.

Reaction time involves three main stages:

1. Detection – Your senses pick up a stimulus (sight, sound, or touch).

2. Processing – Your brain interprets the signal and decides how to respond.

3. Response – Your muscles carry out the action, such as moving your hand or legs.
   
   

This entire process usually happens in fractions of a second, but small differences can have a big impact on performance.

The average reaction time for a healthy adult is usually around 200–250 milliseconds (ms), or about a quarter of a second.

• Visual stimuli (reacting to something you see) take slightly longer, averaging around 250 ms.

• Auditory stimuli (reacting to sound) are faster, averaging around 170 ms.

• Tactile stimuli (reacting to touch) can be even quicker.
  
  

When people ask what is the average reaction time, these are the typical ranges scientists and trainers refer to.

So, what reaction time is good? Generally, anything under 200 ms is considered very good. 

Elite athletes often train to improve their reaction time, and competitive gamers can sometimes achieve reaction times around 150 ms or less.

However, “good” depends on the context:

• Everyday life – A reaction time of 200–250 ms is more than sufficient.

• Athletics – Anything under 200 ms provides a competitive edge.

• Driving – Consistently quick responses improve road safety.
  
  

Your age, health, and level of training can all influence what’s achievable.

Improving reaction time takes consistency and focus. Some effective methods include:

• Sports drills – Activities like sprint starts, ball-catching drills, or agility ladders.

• Video games – Fast-paced games can sharpen hand-eye coordination.

• Reflex training apps – Digital tools that track and challenge your reaction speed.

• Mindfulness and focus exercises – Reducing distractions helps your brain process signals faster.

• Fitness training – Stronger muscles respond more efficiently when activated.
