Separation between our shoes and floor create electrostatic charges on our bodies then discharge to doorknob because of different electrostatic potentials.
We always create electrostatic charges onto our body, while we are walking, getting off car's seat, pushing the trolley in the supermarket and etc, then there is always discharge thru metal object near by you. The different electrostatic potentials cause the discharge thru very small air gap between your body to those objects.
Most of the time we can't feel static shock because it is not high enough to the level that we can feel. Human being can feel the electrostatic discharge (ESD) at about 2,000-3,000 Volts. It is depended on individual sensitivity.
ESD from our body can be a nuisance but are not generally health risk. Attention!!! It may cause fire and explosion risk if there is a spark near by flammable atmospheres.
There was a tip that I tried during wintertime to avoid static shock or reduce severe of shock. I took car’s key or coin touch the doorknob or metal object before you touching it by your hand.
