Constantly touch metal things anytime you pass one like door knobs or railings or anything you see to discharge you before enough static electricity builds up to shock you. Ive made quite a habit of going around touch metal things when ever i pass them.

Also when you think you're already charged up like when you get up and havent touched something in a while, just grab your bedframe with your entire hand so the shocking pressure isnt centralised on your finger.
Same with the car, dont just touch it, palm it.

But these are just theories, and things i have made up myself and possibly deluded myself into believing. however i have been shocked alot less since i started believing these things, coincidence or not?

Alternatively you could just wear gloves or migrate south for the winter
