Every trainer, bike, rider and manner of use creates its own situation. I
used one to rehab a leg before I could walk or ride for real.
I found the stench from the rear tire friction on the resistance roller
contributed to shortening my sessions. I was nothing near a board track
pursuit rider making my frame seem liquid in response to the waves of input
from my physical awesomeness, but I did pour sweat which I addressed with
rags and towels to keep off the hardware and floor.
I took it outside in cooler weather to mitigate the sweat and reduce the
irritation of others at home since that thing with its fan resistance was
loud.
I wouldn't go so far as to attach the demise of that bike frame ('86
RockHopper) with my use in that trainer, but it tore a chain stay with a
crack emanating from the margin of the bridge weld that progressed its way
in a spiral around the stay. No phase of my riding on that bike before
failure was anything near what would have been challenging to its
construction.
Late (after I could walk and ride again) I got some Tacx 4" rollers for my
indoor sessions. I found the response of the bike to my pedaling input more
realistic and mentally engaging. After a while I upgraded to an early
NiteRider headlight and red blinkie tail light. Much happier for my
situation.
Hope all the input helps you reach the best outcome for your situation
