The first thing to do is to understand what factors affect reaction time, which will help answer the basic question of how to improve reaction time. Our reactions depend on the coordinated work of two types of neurons: sensory and motor neurons. Visual, sound, olfactory, tactile, or sensory stimuli are sensed by sensory nerve cells. In response, motor neurons signal the body to perform some action. For more info cehck video and our aticle raisetwice.com/improvement/reaction-time-exercises/. The time interval between the stimulus and the response to the stimulus depends on many factors.
