this is a very interesting question. thank you for asking! i can think of one very good reason why you might experience these symptoms while engaging in a competitive gaming situation: the fight-or-flight response. when you are competing you probably feel stressed. you want to win! and you are very highly focused on performing well. this combination of factors could stimulate your sympathetic nervous system (sns) to respond. the sns responds to acute stress by producing a series of changes within your body often call the "fight or flight response. " during fight-or-flight your pupils dilate to better allow light into the eye and assess escape routes (or in your case see the video field better); your breathing accelerates; your heart rate increases; your blood pressure rises; your digestive processes slow way down; and your bladder sphincter may suddenly relax (oops! ). important to our discussion though is the fact the sns stress response diverts blood flow from the extremities to the muscles. this is probably the reason your hands and feet become cold -- your sns is diverting that blood to your core and to the large muscles of your body in case you must jump up and run away from whatever danger your brain has perceived. fight-or-flight is a primal reaction so the "threat" your sns is responding to could be the competition or the action occurring in the video game itself. when the sns kicks in you usually feel an adrenalin rush. the sns causes your body to be flooded with other hormones too including testosterone and cortisol. if you feel that an sns response is in fact responsible for your cold hands and feet while gaming you can take steps to address the problem. try meditating for several minutes before a competition. focus on your breathing and keep it slow and regulated. if possible focus on your breathing during the competition too. you may be surprised to discover how much you can control your body's response to stress. wishing you well!
when playing competitive video games my hands and feet become very cold. when the game is over it's back to normal y? . it's just when i play a competitive match. if i play a casual/relaxed game i do not get this effect.
