Static shocks in apartment

[New2hkg]

I constantly get static shocks whenever I touch my kitchen/bathroom tap handle.
Sometimes I don't get a shock from the tap handle but I do get a shock from the water stream.

What could be causing this? Especially since I'm (sometimes) getting shocked from the water stream?

This happens most frequently after sitting on my office chair (fabric chair from Pricerite).

Is there any way to earth my chair? Or to find out what's the source of the static?

I have tiled floors.

I have a voltage testing screwdriver but not exactly sure if it could be useful for investigation, or how to best use it.

I have an ESD anti-static wrist strap and connected the alligator clip to a metal kitchen trolley next to my desk, but that does not work either.

Could it be caused by the power strip attached to the under side of my desk?

I didn't have any static shocks with the same office chair in my previous apartment (wood plank floors)

Here is a photo of my chair:

It's a synthetic woven fabric rubbing against other presumably synthetic fabrics. Obvs.

Really low humidity makes it worse, which is why it happens in winter more than summer. Is your air-con/dehumdifier keeping humidity really low in your place? Open some windows, let more fresh (and more humid) air through your house, it'll help.

Wear more cotton and natural fibers, less polyester and synthetics. If you're hairy it can exacerbate it from hairs rubbing against your clothing material (think like rubbing a balloon on your head to make it stand up).

Immediate term fix, if you wear a ring use it to ground yourself regularly as you walk around. I used to do that back home because I get bad static shocks in winter. It just became a habit to touch my ring on taps, door handles, the side of my laptop, anything. Same as pretty much any office because of cheap carpets + work shoes.

You can buy anti-static ground mats to put under your chair, which may/may not help. It might only help if you had bare feet on the mat to stay earthed. Plastic doesn't conduct so maybe you have to run a wire strap to the mat as well like some cars you see haha

does it happen if when touch other metallic objects in the room, door handles, metal table leg, fridge, etc. if yes that is most probably caused by the build up of static electricity. if it is old building and only happens at the presumably metal sink, it could be stay neutral current from a shitty electrical installation.
