The mechanisms by which relaxation techniques may improve reaction time are not yet fully understood. However, there are several possible explanations. One is that relaxation techniques may improve attentional control, which is crucial for effective processing of incoming stimuli. By reducing stress and anxiety, relaxation techniques may help to increase focus and concentration, leading to faster reaction times. In addition, relaxation techniques may also help to improve working memory capacity, which is important for processing and storing information in the brain. By improving working memory, individuals may be able to process and respond to stimuli more efficiently, leading to faster reaction times.
