I wouldn't turn off heat in that room but turn radiator right down so a little heat is in there. We recently tried the turn radiators off in not used rooms and found the house was colder and took longer to heat up. Even with doors closed.
When I was at uni, my mum turned the radiator off in my room and didn’t heat it for about a month. When I came home there were mushrooms growing through the carpet we had to rip it up and get laminate so I’d heat it occasionally
