Wherever I'm walking and my hand collided with my gf arms or my friends it will happen until I can hear the electrostatic collision (it sounds like electric buzz) between my hands and others. Anyone had this? They can feel the itchy of the situation .

How can I reduce this? Any things suitable to use to discharge the electrostatic?
Is it will affect me from the weather surrounding, example the Lighting storm .     

not sure if it's quite true or not....they say lack of sleep contributes to that.
but when i have enough sleeps still i got zapped touching metal stuffs....
wear disposable plastic gloves for me at the end.....
