Here in the office we suffer a lot with static shocks, all day long when people touch each other, open a door or grab a coffee. It's really a pain.
We have A/C on. Air humidity ranges between 40% to 50%. Outside temperature is around 28ºC and indoor temperature is around 23ºC. I don't know if it matters, but the floor is some sort of fake wood layer. I don't know the material.
I don't know what else to say. We have a lot of computers, no-breaks on the floor and electronics devices.
What can be causing these shocks, and how can it be prevented?
