Back in the 1980s when we lived in Calgary, Alberta winter
temperatures could dip to close on -40C on a "cold" day [exclusive of
any wind chill factor] along with 10% relative humidity or less. One
learned very quickly to wear gloves, or shoes with rubber soles, in the
house when holding or turning door handles ....... otherwise a static
spark could be a real wake up moment !
A friend from South Africa visited one winter. He got the shock of a
lifetime with our door handles but was a quicker learner and invested in
gloves.

I did my a spell repairing CRT's during my apprenticeship but the
thing that I was wary of was the + and -80V telex busbars even the
telephone 50V ones would melt a spanner very quickly.
I had a few shocks from 160v DC and a few from 240 AC - I wonder if
thats why I can feel the static on freshly printed output from a laser
printer and hate wifi ;-)

I used to fix TVs with flyback transformers, too. Keep one hand in a
pocket. Bleed the caps, multiple times. Have someone nearby with
???911??? on speed-dial. :-)
...and discharge the CRT, a very large capacitor that seemingly
recharges itself :)
