How to Improve Reaction Time?
Improving your reaction time is possible with practice and proper habits. Train with reflex games and sports that require speed (like tennis or boxing). Getting good sleep is key, as fatigue slows down your response. Additionally, meditation and controlled breathing improve concentration, allowing you to react faster to unexpected stimuli.
Visual vs Auditory Reaction Times
Auditory reaction time (140-160 ms) is faster than visual reaction time (200-250 ms) because sound requires less brain processing. Although light travels faster than sound, the brain takes longer to interpret images than to detect an auditory stimulus. That's why we react sooner to an unexpected noise than to a change in light.
